Treatment of NC Pins Note: Do not connect anything to the NC pins. The NC (not connected) pins are either not connected to any of the internal circuitry or are used as test pins or to reduce noise. If something is connected to the NC pins, the operation of the LSI is not guaranteed. 2. Treatment of Unused Input Pins Note: Fix all unused input pins to high or low level. Generally, the input pins of CMOS products are high-impedance input pins. If unused pins are in their open states, intermediate levels are induced by noise in the vicinity, a passthrough current flows internally, and a malfunction may occur. 3. Processing before Initialization Note: When power is first supplied, the product's state is undefined. The states of internal circuits are undefined until full power is supplied throughout the chip and a low level is input on the reset pin. During the period where the states are undefined, the register settings and the output state of each pin are also undefined. Design your system so that it does not malfunction because of processing while it is in this undefined state. For those products which have a reset function, reset the LSI immediately after the power supply has been turned on. 4. Prohibition of Access to Undefined or Reserved Addresses Note: Access to undefined or reserved addresses is prohibited. The undefined or reserved addresses may be used to expand functions, or test registers may have been be allocated to these addresses. Do not access these registers; the system's operation is not guaranteed if they are accessed. Page iv of xcviii Configuration of This Manual This manual comprises the following items: 1.

Main Revisions and Additions in this Edition (only for revised versions) The list of revisions is a summary of points that have been revised or added to earlier versions. This does not include all of the revised contents. For details, see the actual locations in this manual. 12. Index Page v of xcviii Preface This LSI is an RISC (Reduced Instruction Set Computer) microcomputer which includes a Renesas-original RISC CPU as its core, and the peripheral functions required to configure a system. Target Users: This manual was written for users who will be using this LSI in the design of application systems. Target users are expected to understand the fundamentals of electrical circuits, logical circuits, and microcomputers. Objective: This manual was written to explain the hardware functions and electrical characteristics of this LSI to the target users. Refer to the SH-2A, SH2A-FPU Software Manual for a detailed description of the instruction set. Notes on reading this manual: * In order to understand the overall functions of the chip Read the manual according to the contents. This manual can be roughly categorized into parts on the CPU, system control functions, peripheral functions and electrical characteristics. * In order to understand the details of the CPU's functions Read the SH-2A, SH2A-FPU Software Manual. * In order to understand the details of a register when its name is known Read the index that is the final part of the manual to find the page number of the entry on the register. The addresses, bits, and initial values of the registers are summarized in section 51, List of Registers. Page vi of xcviii * Description of Numbers and Symbols Aspects of the notations for register names, bit names, numbers, and symbolic names in this manual are explained below. (1) Overall notation In descriptions involving the names of bits and bit fields within this manual, the modules and registers to which the bits belong may be clarified by giving the names in the forms "module name"."register name"."bit name" or "register name"."bit name". (2) Register notation The style "register name"_"instance number" is used in cases where there is more than one instance of the same function or similar functions. [Example] CMCSR_0: Indicates the CMCSR register for the compare-match timer of channel 0. (3) Number notation Binary numbers are given as B'nnnn (B' may be omitted if the number is obviously binary), hexadecimal numbers are given as H'nnnn or 0xnnnn, and decimal numbers are given as nnnn. [Examples] Binary: B'11 or 11 Hexadecimal: H'EFA0 or 0xEFA0 Decimal: 1234 (4) Notation for active-low An overbar on the name indicates that a signal or pin is active-low. [Example] WDTOVF (4) (2) 14.2.2 Compare Match Control/Status Register_0, _1 (CMCSR_0, CMCSR_1) CMCSR indicates compare match generation, enables or disables interrupts, and selects the counter input clock. Generation of a WDTOVF signal or interrupt initializes the TCNT value to 0. 14.3 Operation 14.3.1 Interval Count Operation When an internal clock is selected with the CKS1 and CKS0 bits in CMCSR and the STR bit in CMSTR is set to 1, CMCNT starts incrementing using the selected clock. When the values in CMCNT and the compare match constant register (CMCOR) match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1. When the CKS1 and CKS0 bits are set to B'01 at this time, a f/4 clock is selected.

(1) Bit Indicates the bit number or numbers. In the case of a 32-bit register, the bits are arranged in order from 31 to 0. In the case of a 16-bit register, the bits are arranged in order from 15 to 0. (2) Bit name Indicates the name of the bit or bit field. When the number of bits has to be clearly indicated in the field, appropriate notation is included (e.g., ASID[3:0]). A reserved bit is indicated by "-". Certain kinds of bits, such as those of timer counters, are not assigned bit names. In such cases, the entry under Bit Name is blank. (3) Initial value Indicates the value of each bit immediately after a power-on reset, i.e., the initial value. 0: The initial value is 0 1: The initial value is 1 -: The initial value is undefined (4) R/W For each bit and bit field, this entry indicates whether the bit or field is readable or writable, or both writing to and reading from the bit or field are impossible. The notation is as follows: R/W: The bit or field is readable and writable. R/(W): The bit or field is readable and writable. However, writing is only performed to flag clearing. R: The bit or field is readable. "R" is indicated for all reserved bits. When writing to the register, write the value under Initial Value in the bit chart to reserved bits or fields. W: The bit or field is writable. (5) Description Describes the function of the bit or field and specifies the values for writing.

To make this transition, the SLEEP instruction must be performed after setting the STBY bit in the STBCR1 register to 1. However a dummy read of the STBCR1 register is required before executing the SLEEP instruction. If a dummy read is omitted, the CPU executes the SLEEP instruction before the STBY bit is set to 1, thus the system enters sleep mode not software standby mode. A dummy read of the STBCR1 register is indispensable to complete writing to the STBY bit. 11.3.9 DMA Extension Resource 447 Selectors 0 to 7 (DMARS0 to DMARS7) Table amended Table 11.3 DMARS Settings Peripheral Module Setting Value for One Channel ({MID, RID}) MID SD H'A9 B'101010 interface 1 H'AA 12.3.16 Timer Output Master Enable Register (TOER) Page xiv of xcviii 530 Description amended TOER is an 8-bit readable/writable register that enables/disables output settings for output pins TIOC4D, TIOC4C, TIOC3D, TIOC4B, TIOC4A, and TIOC3B. These pins do not output correctly if the TOER bits have not been set. Set TOER of CH3 and CH4 prior to setting TIOR of CH3 and CH4. Set TOER when count operation of TCNT channels 3 and 4 is halted.

See table 12.28. 0 OLSP 0 R/W Output Level Select P* 2 This bit selects the positive phase output level in resetsynchronized PWM mode/complementary PWM mode. See table 12.29. Notes: 1. Setting the TOCL bit to 1 prevents accidental modification when the CPU goes out of control. 2. Clearing the TOCS0 bit to 0 makes this bit setting valid. 3. After power-on reset, 1 can be written only once. After 1 has been written, 0 cannot be written. 4. If there is no dead time, the reverse phase output is the inversion of the forward phase. Set OLSP and OLSN to the same value. 12.3.18 Timer Output Control Register 2 (TOCR2) 536 12.4.2 Synchronous Operation 557 Table note amended Note: * Setting the TOCS bit in TOCR1 to 1 makes this bit setting valid. If there is no dead time, the reverse phase output is the inversion of the forward phase. Set OLSiP and OLSiN to the same value (i = 1, 2, or 3). Description amended Channels 0 to 4 can all be designated for synchronous operation. 12.4.4 Cascaded Operation 563 Description amended For simultaneous input capture of TCNT_1 and TCNT_2 during cascaded operation, additional input capture input pins can be specified by the input capture control register (TICCR). The edge detection that is the condition for input capture uses a signal representing the logical OR of the original input pin and the added input pins.

Page xv of xcviii Item Page Revision (See Manual for Details) 12.4.5 PWM Modes 568 Description amended * PWM output is generated using one TGR as the cycle register and the others as duty registers. The output specified in TIOR is performed by means of compare matches. Upon counter clearing by a cycle register compare match, the output value of each pin is the initial value set in TIOR. If the set values of the cycle and duty registers are identical, the output value does not change when a compare match occurs.

When no dead time generation is selected, set 1 in TDDR and 1/2 the carrier cycle + 1 in TGRA_3 and TGRC_3. Description amended A PWM waveform is generated by output of the output level selected in the timer output control register in the event of a compare-match between a counter and compare register. While TCNTS is counting, compare register and temporary register values are simultaneously compared to create consecutive PWM pulses from 0 to 100%. ...

The waveform in this case has a positive phase with a 100% on-state. 0% duty output is performed when the compare register value is set to the same value as TGRA_3. The waveform in this case has a positive phase with a 100% off-state.

The sixteen 32-bit general registers are numbered R0 to R15. General registers are used for data processing and address calculation. R0 is also used as an index register. Several instructions have R0 fixed as their only usable register. R15 is used as the hardware stack pointer (SP). Saving and restoring the status register (SR) and program counter (PC) in exception handling is accomplished by referencing the stack using R15. 31 0 R0*1 R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 R12 R13 R14 R15, SP (hardware stack pointer)*2 Notes: 1. R0 functions as an index register in the indexed register indirect addressing mode and indexed GBR indirect addressing mode. In some instructions, R0 functions as a fixed source register or destination register. 2. R15 functions as a hardware stack pointer (SP) during exception processing.

The status register indicates instruction processing states. The global base register functions as a base address for the GBR indirect addressing mode to transfer data to the registers of on-chip peripheral modules. The vector base register functions as the base address of the exception handling vector area (including interrupts). The jump table base register functions as the base address of the function table area. 31 14 13 9 8 7 6 5 4 3 2 1 0 BO CS M Q I[3:0] S T 31 Status register (SR) 0 GBR Global base register (GBR) 31 0 VBR Vector base register (VBR) 31 0 TBR Jump table base register (TBR) Figure 2.2 Control Registers (1) Status Register (SR) Bit: 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 - - - - - - - - - - - - - - - - Initial value: R/W: 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 - BO CS - - - M Q - - S T 0 R 0 R/W 0 R/W 0 R 0 R 0 R R/W R/W 0 R 0 R R/W R/W Initial value: R/W: Page 58 of 3088 I[3:0] 1 R/W 1 R/W 1 R/W 1 R/W R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Bit Bit Name Initial Value 31 to 15 All 0 Section 2 CPU R/W Description R Reserved These bits are always read as 0.

MACH and MACL store the results of multiply or multiply and accumulate operations. PR stores the return address from a subroutine procedure. PC points four bytes ahead of the current instruction and controls the flow of the processing. 31 0 Multiply and accumulate register high (MACH) and multiply and accumulate register low (MACL): Store the results of multiply or multiply and accumulate operations. 0 Procedure register (PR): Stores the return address from a subroutine procedure. 0 Program counter (PC): Indicates the four bytes ahead of the current instruction. MACH MACL 31 PR 31 PC Figure 2.3 System Registers (1) Multiply and Accumulate Register High (MACH) and Multiply and Accumulate Register Low (MACL) MACH and MACL are used as the addition value in a MAC instruction, and store the result of a MAC or MUL instruction. (2) Procedure Register (PR) PR stores the return address of a subroutine call using a BSR, BSRF, or JSR instruction, and is referenced by a subroutine return instruction (RTS). (3) Program Counter (PC) PC points four bytes ahead of the instruction being executed. Page 60 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 2.1.4 Section 2 CPU Register Banks For the nineteen 32-bit registers comprising general registers R0 to R14, control register GBR, and system registers MACH, MACL, and PR, high-speed register saving and restoration can be carried out using a register bank. The register contents are automatically saved in the bank after the CPU accepts an interrupt that uses a register bank. Restoration from the bank is executed by issuing a RESBANK instruction in an interrupt processing routine. This LSI has 15 banks. For details, see the SH-2A, SH2A-FPU Software Manual and section 7.8, Register Banks. 2.1.5 Initial Values of Registers Table 2.1 lists the values of the registers after a reset.

If the size of memory operand is a byte (8 bits) or a word (16 bits), it is changed into a longword by expanding the sign-part when loaded into a register. 31 0 Longword Figure 2.4 Data Format in Registers 2.2.2 Data Formats in Memory Memory data formats are classified into bytes, words, and longwords. Memory can be accessed in 8-bit bytes, 16-bit words, or 32-bit longwords. A memory operand of fewer than 32 bits is stored in a register in sign-extended or zero-extended form. A word operand should be accessed at a word boundary (an even address of multiple of two bytes: address 2n), and a longword operand at a longword boundary (an even address of multiple of four bytes: address 4n). Otherwise, an address error will occur. A byte operand can be accessed at any address. Only big-endian byte order can be selected for the data format. Data formats in memory are shown in figure 2.5. Address m + 3 Address m + 1 Address m 31 Address m + 2 23 Byte Address 2n Address 4n 15 Byte 7 Byte Word 0 Byte Word Longword Big endian Figure 2.5 Data Formats in Memory Page 62 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 2.2.3 Section 2 CPU Immediate Data Format Byte (8-bit) immediate data is located in an instruction code. Immediate data accessed by the MOV, ADD, and CMP/EQ instructions is sign-extended and handled in registers as longword data. Immediate data accessed by the TST, AND, OR, and XOR instructions is zero-extended and handled as longword data. Consequently, AND instructions with immediate data always clear the upper 24 bits of the destination register. 20-bit immediate data is located in the code of a MOVI20 or MOVI20S 32-bit transfer instruction. The MOVI20 instruction stores immediate data in the destination register in sign-extended form. The MOVI20S instruction shifts immediate data by eight bits in the upper direction, and stores it in the destination register in sign-extended form. Word or longword immediate data is not located in the instruction code, but rather is stored in a memory table. The memory table is accessed by an immediate data transfer instruction (MOV) using the PC relative addressing mode with displacement. See examples given in section 2.3.1 (10), Immediate Data. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 63 of 3088 SH7268 Group, SH7269 Group Section 2 CPU 2.3 Instruction Features 2.3.1 RISC-Type Instruction Set Instructions are RISC type. This section details their functions. (1) 16-Bit Fixed-Length Instructions Basic instructions have a fixed length of 16 bits, improving program code efficiency. (2) 32-Bit Fixed-Length Instructions The SH-2A additionally features 32-bit fixed-length instructions, improving performance and ease of use. (3) One Instruction per State Each basic instruction can be executed in one cycle using the pipeline system. (4) Data Length Longword is the standard data length for all operations. Memory can be accessed in bytes, words, or longwords. Byte or word data in memory is sign-extended and handled as longword data. Immediate data is sign-extended for arithmetic operations or zero-extended for logic operations. It is also handled as longword data. Table 2.2 Sign Extension of Word Data SH2-A CPU MOV.W ADD .DATA.W Description @(disp,PC),R1 Data is sign-extended to 32 bits, and R1 becomes R1,R0 H'00001234. It is next ......... operated upon by an ADD H'1234 instruction. Example of Other CPU ADD.W #H'1234,R0 Note: @(disp, PC) accesses the immediate data. (5) Load-Store Architecture Basic operations are executed between registers. For operations that involve memory access, data is loaded to the registers and executed (load-store architecture). Instructions such as AND that manipulate bits, however, are executed directly in memory. Page 64 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (6) Section 2 CPU Delayed Branch Instructions With the exception of some instructions, unconditional branch instructions, etc., are executed as delayed branch instructions. With a delayed branch instruction, the branch is taken after execution of the instruction immediately following the delayed branch instruction. This reduces disturbance of the pipeline control when a branch is taken. In a delayed branch, the actual branch operation occurs after execution of the slot instruction. However, instruction execution such as register updating excluding the actual branch operation, is performed in the order of delayed branch instruction delay slot instruction. For example, even though the contents of the register holding the branch destination address are changed in the delay slot, the branch destination address remains as the register contents prior to the change. Table 2.3 Delayed Branch Instructions SH-2A CPU Description Example of Other CPU BRA TRGET R1,R0 R1,R0 Executes the ADD before branching to TRGET. ADD.W ADD BRA TRGET (7) Unconditional Branch Instructions with No Delay Slot The SH-2A additionally features unconditional branch instructions in which a delay slot instruction is not executed. This eliminates unnecessary NOP instructions, and so reduces the code size. (8) Multiply/Multiply-and-Accumulate Operations 16-bit x 16-bit 32-bit multiply operations are executed in one to two cycles. 16-bit x 16-bit + 64-bit 64-bit multiply-and-accumulate operations are executed in two to three cycles. 32-bit x 32-bit 64-bit multiply and 32-bit x 32-bit + 64-bit 64-bit multiply-and-accumulate operations are executed in two to four cycles. (9) T Bit The T bit in the status register (SR) changes according to the result of the comparison. Whether a conditional branch is taken or not taken depends upon the T bit condition (true/false). The number of instructions that change the T bit is kept to a minimum to improve the processing speed. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 65 of 3088 SH7268 Group, SH7269 Group Section 2 CPU Table 2.4 T Bit SH-2A CPU Description Example of Other CPU CMP/GE R1,R0 T bit is set when R0 R1. CMP.W R1,R0 BT TRGET0 BGE TRGET0 BF TRGET1 The program branches to TRGET0 when R0 R1 and to TRGET1 when R0 < R1. BLT TRGET1 ADD #-1,R0 T bit is not changed by ADD. SUB.W #1,R0 CMP/EQ #0,R0 T bit is set when R0 = 0. BEQ TRGET BT TRGET The program branches if R0 = 0. (10) Immediate Data Byte immediate data is located in an instruction code. Word or longword immediate data is not located in instruction codes but in a memory table. The memory table is accessed by an immediate data transfer instruction (MOV) using the PC relative addressing mode with displacement. With the SH-2A, 17- to 28-bit immediate data can be located in an instruction code. However, for 21- to 28-bit immediate data, an OR instruction must be executed after the data is transferred to a register.

That value is transferred to the register by loading the immediate data during the execution of the instruction, and the data is accessed in register indirect addressing mode. With the SH-2A, when data is referenced using an absolute address not exceeding 28 bits, it is also possible to transfer immediate data located in the instruction code to a register and to reference the data in register indirect addressing mode. However, when referencing data using an absolute address of 21 to 28 bits, an OR instruction must be used after the data is transferred to a register.

Figure 2.6 shows the transitions between the states. Manual reset from any state Power-on reset from any state Manual reset state Power-on reset state Reset state NMI interrupt, realtime clock alarm interrupt, change in the level of a pin that initiates release, and power-on reset Reset canceled Interrupt source or DMA address error occurs Exception handling state Bus request cleared Exception handling Bus request source generated occurs Bus-released state Bus request generated Bus request generated Bus request cleared Sleep mode NMI interrupt or IRQ interrupt occurs Exception handling ends Bus request cleared Program execution state STBY bit cleared for SLEEP instruction STBY bit set and DEEP bit cleared for SLEEP instruction Software standby mode STBY and DEEP bits set for SLEEP instruction Deep standby mode Power-down state Figure 2.6 Transitions between Processing States R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 99 of 3088 Section 2 CPU (1) SH7268 Group, SH7269 Group Reset State In the reset state, the CPU is reset. There are two kinds of reset, power-on reset and manual reset. (2) Exception Handling State The exception handling state is a transient state that occurs when exception handling sources such as resets or interrupts alter the CPU's processing state flow. For a reset, the initial values of the program counter (PC) (execution start address) and stack pointer (SP) are fetched from the exception handling vector table and stored; the CPU then branches to the execution start address and execution of the program begins. For an interrupt, the stack pointer (SP) is accessed and the program counter (PC) and status register (SR) are saved to the stack area. The exception service routine start address is fetched from the exception handling vector table; the CPU then branches to that address and the program starts executing, thereby entering the program execution state. (3) Program Execution State In the program execution state, the CPU sequentially executes the program. (4) Power-Down State In the power-down state, the CPU stops operating to reduce power consumption. The SLEEP instruction places the CPU in sleep mode, software standby mode, or deep standby mode. (5) Bus-Released State In the bus-released state, the CPU releases bus to a device that has requested it.

A value is NaN in the following case: * Sign bit: Don't care * Exponent field: All bits are 1 * Fraction field: At least one bit is 1 The NaN is a signaling NaN (sNaN) if the MSB of the fraction field is 1, and a quiet NaN (qNaN) if the MSB is 0. 31 30 x 23 22 11111111 0 Nxxxxxxxxxxxxxxxxxxxxxx N = 1: sNaN N = 0: qNaN Figure 3.3 Single-Precision NaN Bit Pattern An sNaN is input in an operation, except copy, FABS, and FNEG, that generates a floating-point value. * When the EN.V bit in FPSCR is 0, the operation result (output) is a qNaN. * When the EN.V bit in FPSCR is 1, an invalid operation exception will generate FPU exception processing. In this case, the contents of the operation destination register are unchanged. If a qNaN is input in an operation that generates a floating-point value, and an sNaN has not been input in that operation, the output will always be a qNaN irrespective of the setting of the EN.V bit in FPSCR. An exception will not be generated in this case.

In the SH2A-FPU, the DN bit in the status register FPSCR is always set to 1, therefore a denormalized number (source operand or operation result) is always flushed to 0 in a floatingpoint operation that generates a value (an operation other than copy, FNEG, or FABS). When the DN bit in FPSCR is 0, a denormalized number (source operand or operation result) is processed as it is. See the individual instruction descriptions for details of floating-point operations when a denormalized number is input.

FPUL is a 32-bit system register that is accessed from the CPU side by means of LDS and STS instructions. For example, to convert the integer stored in general register R1 to a single-precision floating-point number, the processing flow is as follows: R1 (LDS instruction) FPUL (single-precision FLOAT instruction) FR1 Page 110 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 3.4 Section 3 Floating-Point Unit (FPU) Rounding In a floating-point instruction, rounding is performed when generating the final operation result from the intermediate result. Therefore, the result of combination instructions such as FMAC will differ from the result when using a basic instruction such as FADD, FSUB, or FMUL. Rounding is performed once in FMAC, but twice in FADD, FSUB, and FMUL. Which of the two rounding methods is to be used is determined by the RM bits in FPSCR. FPSCR.RM[1:0] = 00: Round to Nearest FPSCR.RM[1:0] = 01: Round to Zero (1) Round to Nearest The operation result is rounded to the nearest expressible value. If there are two nearest expressible values, the one with an LSB of 0 is selected. Emax -P If the unrounded value is 2 (2 - 2 ) or more, the result will be infinity with the same sign as the unrounded value. The values of Emax and P, respectively, are 127 and 24 for single-precision, and 1023 and 53 for double-precision. (2) Round to Zero The digits below the round bit of the unrounded value are discarded. If the unrounded value is larger than the maximum expressible absolute value, the value will become the maximum expressible absolute value. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 111 of 3088 Section 3 Floating-Point Unit (FPU) 3.5 FPU Exceptions 3.5.1 FPU Exception Sources SH7268 Group, SH7269 Group FPU exceptions may occur on floating-point operation instruction and the exception sources are as follows: * FPU error (E): When FPSCR.DN = 0 and a denormalized number is input (No error occurs in the SH2A-FPU) * Invalid operation (V): In case of an invalid operation, such as NaN input * Division by zero (Z): Division with a zero divisor * Overflow (O): When the operation result overflows * Underflow (U): When the operation result underflows * Inexact exception (I): When overflow, underflow, or rounding occurs The FPU exception cause field in FPSCR contains bits corresponding to all of above sources E, V, Z, O, U, and I, and the FPU exception flag and enable fields in FPSCR contain bits corresponding to sources V, Z, O, U, and I, but not E. Thus, FPU errors cannot be disabled. When an FPU exception occurs, the corresponding bit in the FPU exception cause field is set to 1, and 1 is added to the corresponding bit in the FPU exception flag field. When an FPU exception does not occur, the corresponding bit in the FPU exception cause field is cleared to 0, but the corresponding bit in the FPU exception flag field remains unchanged. 3.5.2 FPU Exception Handling FPU exception handling is initiated in the following cases: * FPU error (E): FPSCR.DN = 0 and a denormalized number is input (No error occurs in the SH2A-FPU) * Invalid operation (V): FPSCR.Enable.V = 1 and invalid operation * Division by zero (Z): FPSCR.Enable.Z = 1 and division with a zero divisor * Overflow (O): FPSCR.Enable.O = 1 and instruction with possibility of operation result overflow * Underflow (U): FPSCR.Enable.U = 1 and instruction with possibility of operation result underflow * Inexact exception (I): FPSCR.Enable.I = 1 and instruction with possibility of inexact operation result Page 112 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 3 Floating-Point Unit (FPU) These possibilities of each exceptional handling on floating-point operation are shown in the individual instruction descriptions. All exception events that originate in the floating-point operation are assigned as the same FPU exceptional handling event. The meaning of an exception generated by floating-point operation is determined by software by reading from FPSCR and interpreting the information it contains. Also, the destination register is not changed when FPU exception handling operation occurs. Except for the above, the FPU disables exception handling. In every processing, the bit corresponding to source V, Z, O, U, or I is set to 1, and a default value is generated as the operation result. * Invalid operation (V): qNaN is generated as the result. * Division by zero (Z): Infinity with the same sign as the unrounded value is generated. * Overflow (O): When rounding mode = RZ, the maximum normalized number, with the same sign as the unrounded value, is generated. When rounding mode = RN, infinity with the same sign as the unrounded value is generated. * Underflow (U): Zero with the same sign as the unrounded value is generated. * Inexact exception (I): An inexact result is generated.

In this mode, this LSI operates as follows: After the power-on reset is canceled, the initial value (execution start address) of the program counter (PC) and the initial value of the stack pointer (SP) are fetched from the exception handling vector table located in the memory connected to the CS0 space, then program execution is started. 4.3.2 Boot Mode 2 In boot mode 2, booting up is from NAND flash memory, which is connected to the NAND flash memory controller. Suitable NAND flash memory has a large block size (2048 + 64) and takes five-byte addresses (has a capacity of 2 GB or greater). The flow of initiation in boot mode 2 is as described below. (1) Execution from on-Chip ROM of the Program for Boot Initiation After release from the power-on reset state, the CPU executes the boot initiation program that has been stored in on-chip ROM (and is not publicly disclosed). (2) Transfer of the Loader Program The 8-KB loader program is transferred from NAND flash memory, which is connected to the NAND flash memory controller, to the first location of the high-speed on-chip RAM. Transfer and checking by the loader program proceed as follows. (a) A search is conducted to find the block which holds the loader program. Block addresses 0 to 1023 (max.) (b) The 8-KB (16-sector) loader program is read out and transferred to high-speed on-chip RAM. Once transfer of the loader program has been completed, execution by the CPU jumps to highspeed on-chip RAM so that it can start executing the transferred loader program.

The flow of initiation in boot mode 3 is as described below. (1) Execution from on-Chip ROM of the Program for Boot Initiation After release from the power-on reset state, the CPU executes the boot initiation program that has been stored in on-chip ROM (and is not publicly disclosed).

The clock pulse generator consists of a crystal oscillator, PLL circuits, and divider circuits. 5.1 Features * Four clocks generated independently A CPU clock (I) for the CPU and cache; an internal bus clock (B) for the I-Bus; peripheral clock 0 (P0) for the on-chip peripheral modules; peripheral clock 1 (P1 = CKIO) for the external bus interface * Frequency change function CPU and internal bus clock frequencies can be changed independently using the PLL (phase locked loop) circuits and divider circuits within this module. Frequencies are changed by software using frequency control register (FRQCR) settings. * Power-down mode control The clock can be stopped in sleep mode, software standby mode, and deep standby mode, and specific modules can be stopped using the module standby function. For details on clock control in the power-down modes, see section 49, Power-Down Modes. * SSCG function The CPU's internal PLL (phase locked loop) circuit includes an SSCG (spread spectrum clock generator). The SSCG can be used to decrease the peak value of EMI (electromagnetic interference) noise by frequency modulation, that is, by slightly modulating the output frequency. The specification of the SSCG for this LSI is as follows.

(2) PLL Circuit The PLL circuit is capable of multiplying the frequency of the input clock signal from the crystal oscillator or EXTAL pin by 20. (3) Divider 1 Divider 1 generates a clock signal whose operating frequency can be used for the CPU clock, internal bus clock, peripheral clock 0, and peripheral clock 1. The division ratio of the CPU clock and the internal bus clock is set by the frequency control register. The division ratios for peripheral clocks 1 and 0 are fixed to 1/4 and 1/8, respectively. (4) Clock Frequency Control Circuit The clock frequency control circuit controls the clock frequency using the frequency control register (FRQCR). (5) Standby Control Circuit The standby control circuit controls the states of the on-chip oscillation circuit and other modules during clock switching, or sleep, software standby or deep standby mode. In addition, the standby control register is provided to control the power-down mode of other modules. For details on the standby control register, see section 49, Power-Down Modes. (6) Frequency Control Register (FRQCR) The frequency control register (FRQCR) has control bits assigned for the following functions: clock output/non-output from the CKIO pin during software standby mode and the frequency division ratio of the CPU clock (I) and the internal bus clock (B).

The division rate can be changed by software through the frequency control register (FRQCR). 5.5.1 Changing the Division Ratio The division rate of divider can be changed by the following operation. 1.

After the register bits (IFC[1:0] and BFC[1:0]) have been set, the clock is supplied of the new division ratio. Note: When executing the SLEEP instruction after the frequency has been changed, be sure to read the frequency control register (FRQCR) three times before executing the SLEEP instruction.

Place the crystal resonator and capacitors (CL1 and CL2) as close to pins Xin and Xout as possible. Furthermore, to avoid inductance so that oscillation is correct, use the points where the capacitors are connected to the crystal resonator in common and do not place wiring patterns close to these components. Since the design of the user board is closely connected with the effective characteristics of the crystal resonator, refer to the example of connection of the crystal resonator that is introduced in this section and perform thorough evaluation on the user side as well. The rated value of the crystal resonator will vary with the floating capacitances and so on of the crystal resonator and mounted circuit, so proceed with decisions on the basis of full discussions with the maker of the crystal resonator. Ensure that voltages applied to the clock pins do not exceed the maximum rated values. Although the feedback resistor is included in this LSI, an external feedback resistor may be required in some cases. This depends on the characteristics of the crystal resonator. Set the parameters (of resistors and capacitors) with thorough evaluation on the user side.

Since the analog power supply pins of the PLL are sensitive to the noise, the system may malfunction due to inductive interference at the other power supply pins. To prevent such malfunction, the analog power supply pins and the digital power supply pins Vcc and PVcc should not supply the same resources on the board if at all possible. Ensure that PLLVcc has the same electric potential as PVcc.

Slot illegal instructions Starts from the decoding of undefined code placed directly after a delayed branch instruction (delay slot) (including FPU instructions and FPU-related CPU instructions in FPU module standby state), of instructions that rewrite the PC, of 32-bit instructions, of the RESBANK instruction, of the DIVS instruction, or of the DIVU instruction. Integer division exceptions Starts when detecting division-by-zero exception or overflow exception caused by division of the negative maximum value (H'80000000) by -1. FPU exceptions Starts when detecting invalid floating point operation exception defined by IEEE standard 754, division-by-zero exception, overflow, underflow, or inexact exception. Instructions Also starts when qNaN or is input to the source for a floating point operation instruction when the QIS bit in FPSCR is set. When exception handling starts, the CPU operates as follows: (1) Exception Handling Triggered by Reset The initial values of the program counter (PC) and stack pointer (SP) are fetched from the exception handling vector table (PC and SP are respectively the H'00000000 and H'00000004 addresses for power-on resets and the H'00000008 and H'0000000C addresses for manual resets). See section 6.1.3, Exception Handling Vector Table, for more information. The vector base register (VBR) is then initialized to H'00000000, the interrupt mask level bits (I3 to I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized to 0. The BN bit in IBNR of the interrupt controller is also initialized to 0. The floating point status/control register (FPSCR) is initialized to H'00040001 by a power-on reset. The program begins running from the PC address fetched from the exception handling vector table. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 143 of 3088 Section 6 Exception Handling (2) SH7268 Group, SH7269 Group Exception Handling Triggered by Address Errors, Register Bank Errors, Interrupts, and Instructions SR and PC are saved to the stack indicated by R15. In the case of interrupt exception handling other than NMI and user break with usage of the register banks enabled, general registers R0 to R14, control register GBR, system registers MACH, MACL, and PR, and the vector table address offset of the interrupt exception handling to be executed are saved to the register banks. In the case of exception handling due to address errors, register bank errors, NMI interrupts, user break interrupts, or instructions, saving to a register bank is not performed. When saving is performed to all register banks, automatic saving to the stack is performed instead of register bank saving. In this case, an interrupt controller setting must have been made so that register bank overflow exceptions are not accepted (the BOVE bit in IBNR of the interrupt controller is 0). If a setting to accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the interrupt controller is 1), register bank overflow exception will be generated. In the case of interrupt exception handling, the interrupt priority level is written to the I3 to I0 bits in SR. In the case of exception handling due to an address error or instruction, the I3 to I0 bits are not affected. The exception service routine start address is then fetched from the exception handling vector table and the program begins running from that address. 6.1.3 Exception Handling Vector Table Before exception handling begins running, the exception handling vector table must be set in memory. The exception handling vector table stores the start addresses of exception service routines. (The reset exception handling table holds the initial values of PC and SP.) All exception sources are given different vector numbers and vector table address offsets, from which the vector table addresses are calculated. During exception handling, the start addresses of the exception service routines are fetched from the exception handling vector table, which is indicated by this vector table address.

There are two kinds of reset, power-on and manual. As shown in table 6.6, the CPU state is initialized in both a power-on reset and a manual reset. The FPU state is initialized by a power-on reset, but not by a manual reset. On-chip peripheral module registers except a few registers are also initialized by a power-on reset, but not by a manual reset.

To reliably reset this LSI, the RES pin should be kept at the low level for the duration of the oscillation settling time at power-on or when in software standby mode (when the clock is halted), or at least 20-tcyc when the clock is running. In the power-on reset state, the internal state of the CPU and all the on-chip peripheral module registers are initialized. See section 53.1, Pin States, for the status of individual pins during the power-on reset state. In the power-on reset state, power-on reset exception handling starts when the RES pin is first driven low for a fixed period and then returned to high. The CPU operates as follows: 1. The initial value (execution start address) of the program counter (PC) is fetched from the exception handling vector table. 2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table. 3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized to 0. The BN bit in IBNR of the interrupt controller is also initialized to 0. FPSCR is initialized to H'00040001 4. The values fetched from the exception handling vector table are set in the PC and SP, and the program begins executing. Be certain to always perform power-on reset processing when turning the system power on. (2) Power-On Reset by Means of User Debugging Interface Reset Assert Command When the user debugging interface reset assert command is set, this LSI enters the power-on reset state. Power-on reset by means of the user debugging interface reset assert command is equivalent to power-on reset by means of the RES pin. Setting the user debugging interface reset negate command cancels the power-on reset state. The time required between the user debugging interface reset assert command and the user debugging interface reset negate command is the same as the time to keep the RES pin low to initiate a power-on reset. In the power-on reset state generated by the user debugging interface reset assert command, setting the user debugging interface reset negate command starts power-on reset exception handling. The CPU operates in the same way as when a power-on reset was caused by the RES pin. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 149 of 3088 Section 6 Exception Handling (3) SH7268 Group, SH7269 Group Power-On Reset Initiated by Watchdog Timer When a setting is made for a power-on reset to be generated in watchdog timer mode of the watchdog timer, and WTCNT of the watchdog timer overflows, this LSI enters the power-on reset state. In this case, WRCSR of the watchdog timer and FRQCR of the clock pulse generator are not initialized by the reset signal generated by the watchdog timer. If a reset caused by the RES pin or the user debugging interface reset assert command occurs simultaneously with a reset caused by watchdog timer overflow, the reset caused by the RES pin or the user debugging interface reset assert command has priority, and the WOVF bit in WRCSR is cleared to 0. When power-on reset exception processing is started by the watchdog timer, the CPU operates in the same way as when a power-on reset was caused by the RES pin. 6.2.4 (1) Manual Reset Manual Reset Initiated by Watchdog Timer When a setting is made for a manual reset to be generated in watchdog timer mode of the watchdog timer, and WTCNT of the watchdog timer overflows, this LSI enters the manual reset state. When manual reset exception processing is started by the watchdog timer, the CPU operates as follows: 1. The initial value (execution start address) of the program counter (PC) is fetched from the exception handling vector table. 2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table. 3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized to 0. The BN bit in IBNR of interrupt controller is also initialized to 0. 4. The values fetched from the exception handling vector table are set in the PC and SP, and the program begins executing.

The CPU and the BN bit in IBNR of the interrupt controller are initialized by a manual reset. The FPU and other modules are not initialized.

When the executing instruction then finishes, address error exception handling starts. The CPU operates as follows: 1. The exception service routine start address which corresponds to the address error that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the last executed instruction. 4. After jumping to the exception service routine start address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. 6.4 Register Bank Errors 6.4.1 Register Bank Error Sources (1) Bank Overflow In the state where saving has already been performed to all register bank areas, bank overflow occurs when acceptance of register bank overflow exception has been set by the interrupt controller (the BOVE bit in IBNR of the interrupt controller is set to 1) and an interrupt that uses a register bank has occurred and been accepted by the CPU. (2) Bank Underflow Bank underflow occurs when an attempt is made to execute a RESBANK instruction while saving has not been performed to register banks. 6.4.2 Register Bank Error Exception Handling When a register bank error occurs, register bank error exception handling starts. The CPU operates as follows: 1. The exception service routine start address which corresponds to the register bank error that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the last executed instruction for a bank overflow, and the start address of the executed RESBANK instruction for a bank underflow. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 153 of 3088 Section 6 Exception Handling SH7268 Group, SH7269 Group To prevent multiple interrupts from occurring at a bank overflow, the priority level of the interrupt that caused the bank overflow is written to the interrupt mask level bits (I3 to I0) of the status register (SR). 4. After jumping to the exception service routine start address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. 6.5 Interrupts 6.5.1 Interrupt Sources The sources that start interrupt exception handling are divided into NMI, user break, user debugging interface, IRQ, PINT, and on-chip peripheral modules. Each interrupt source is allocated a different vector number and vector table offset. See table 7.4 in section 7, Interrupt Controller, for more information on vector numbers and vector table address offsets. Page 154 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 6.5.2 Section 6 Exception Handling Interrupt Priority Level The interrupt priority order is predetermined. When multiple interrupts occur simultaneously (overlap), the interrupt controller determines their relative priorities and starts exception handling according to the results. The priority order of interrupts is expressed as priority levels 0 to 16, with priority 0 the lowest and priority 16 the highest. The NMI interrupt has priority 16 and cannot be masked, so it is always accepted. The priority level of user break and user debugging interface interrupts is 15. Priority levels of IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts can be set freely using the interrupt priority registers 01, 02, and 05 to 26 (IPR01, IPR02, and IPR05 to IPR26) of the interrupt controller as shown in table 6.8. The priority levels that can be set are 0 to 15. Level 16 cannot be set. See section 7.3.1, Interrupt Priority Registers 01, 02, 05 to 26 (IPR01, IPR02, IPR05 to IPR26), for details of IPR01, IPR02, and IPR05 to IPR26. Table 6.8 Interrupt Priority Order Type Priority Level Comment NMI 16 Fixed priority level. Cannot be masked. User break 15 Fixed priority level. User debugging interface 15 Fixed priority level. IRQ 0 to 15 Set with interrupt priority registers 01, 02, and 05 to 26 (IPR01, IPR02, and IPR05 to IPR26). PINT On-chip peripheral module R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 155 of 3088 Section 6 Exception Handling 6.5.3 SH7268 Group, SH7269 Group Interrupt Exception Handling When an interrupt occurs, its priority level is ascertained by the interrupt controller. NMI is always accepted, but other interrupts are only accepted if they have a priority level higher than the priority level set in the interrupt mask level bits (I3 to I0) of the status register (SR). When an interrupt is accepted, interrupt exception handling begins. In interrupt exception handling, the CPU fetches the exception service routine start address which corresponds to the accepted interrupt from the exception handling vector table, and saves SR and the program counter (PC) to the stack. In the case of interrupt exception handling other than NMI and user break with usage of the register banks enabled, general registers R0 to R14, control register GBR, system registers MACH, MACL, and PR, and the vector table address offset of the interrupt exception handling to be executed are saved in the register banks. In the case of exception handling due to address errors, NMI interrupts, user break interrupts, or instructions, saving is not performed to the register banks. If saving has been performed to all register banks (0 to 14), automatic saving to the stack is performed instead of register bank saving. In this case, an interrupt controller setting must have been made so that register bank overflow exceptions are not accepted (the BOVE bit in IBNR of the interrupt controller is 0). If a setting to accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the interrupt controller is 1), register bank overflow exception occurs. Next, the priority level value of the accepted interrupt is written to the I3 to I0 bits in SR. For NMI, however, the priority level is 16, but the value set in the I3 to I0 bits is H'F (level 15). Then, after jumping to the start address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. See section 7.6, Operation, for further details of interrupt exception handling.

Table 6.9 Types of Exceptions Triggered by Instructions Type Source Instruction Trap instruction TRAPA Slot illegal instructions Undefined code placed immediately after a delayed branch instruction (delay slot) (including FPU instructions and FPU-related CPU instructions in FPU module standby state), instructions that rewrite the PC, 32-bit instructions, RESBANK instruction, DIVS instruction, and DIVU instruction Comment Delayed branch instructions: JMP, JSR, BRA, BSR, RTS, RTE, BF/S, BT/S, BSRF, BRAF Instructions that rewrite the PC: JMP, JSR, BRA, BSR, RTS, RTE, BT, BF, TRAPA, BF/S, BT/S, BSRF, BRAF, JSR/N, RTV/N 32-bit instructions: BAND.B, BANDNOT.B, BCLR.B, BLD.B, BLDNOT.B, BOR.B, BORNOT.B, BSET.B, BST.B, BXOR.B, MOV.B@disp12, MOV.W@disp12, MOV.L@disp12, MOVI20, MOVI20S, MOVU.B, MOVU.W. General illegal instructions Undefined code anywhere besides in a delay slot (including FPU instructions and FPU-related CPU instructions in FPU module standby state) Integer division exceptions Division by zero DIVU, DIVS Negative maximum value / (-1) DIVS FPU exceptions Starts when detecting invalid FADD, FSUB, FMUL, FDIV, FMAC, operation exception defined by FCMP/EQ, FCMP/GT, FLOAT, FTRC, IEEE754, division-by-zero FCNVDS, FCNVSD, FSQRT exception, overflow, underflow, or inexact exception. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 157 of 3088 Section 6 Exception Handling 6.6.2 SH7268 Group, SH7269 Group Trap Instructions When a TRAPA instruction is executed, trap instruction exception handling starts. The CPU operates as follows: 1. The exception service routine start address which corresponds to the vector number specified in the TRAPA instruction is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the TRAPA instruction. 4. After jumping to the exception service routine start address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. 6.6.3 Slot Illegal Instructions An instruction placed immediately after a delayed branch instruction is called the "instruction placed in a delay slot". When the instruction placed in the delay slot is undefined code (including FPU instructions and FPU-related CPU instructions in FPU module standby state), an instruction that rewrites the PC, a 32-bit instruction, an RESBANK instruction, a DIVS instruction, or a DIVU instruction, slot illegal exception handling starts when such kind of instruction is decoded. When the FPU has entered a module standby state, the floating point operation instruction and FPU-related CPU instructions are handled as undefined codes. If these instructions are placed in a delay slot and then decoded, a slot illegal instruction exception handling starts. The CPU operates as follows: 1. The exception service routine start address is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the jump address of the delayed branch instruction immediately before the undefined code, the instruction that rewrites the PC, the 32-bit instruction, the RESBANK instruction, the DIVS instruction, or the DIVU instruction. 4. After jumping to the exception service routine start address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. Page 158 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 6.6.4 Section 6 Exception Handling General Illegal Instructions When an undefined code, including FPU instructions and FPU-related CPU instructions in FPU module standby state, placed anywhere other than immediately after a delayed branch instruction, i.e., in a delay slot, is decoded, general illegal instruction exception handling starts. When the FPU has entered a module standby state, the floating point instruction and FPU-related CPU instructions are handled as undefined codes. If these instructions are placed anywhere other than immediately after a delayed branch instruction (i.e., in a delay slot) and then decoded, general illegal instruction exception handling starts. In general illegal instruction exception handling, the CPU handles general illegal instructions in the same way as slot illegal instructions. Unlike processing of slot illegal instructions, however, the program counter value stored is the start address of the undefined code. 6.6.5 Integer Division Exceptions When an integer division instruction performs division by zero or the result of integer division overflows, integer division instruction exception handling starts. The instructions that may become the source of division-by-zero exception are DIVU and DIVS. The only source instruction of overflow exception is DIVS, and overflow exception occurs only when the negative maximum value is divided by -1. The CPU operates as follows: 1. The exception service routine start address which corresponds to the integer division exception that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the integer division instruction at which the exception occurred. 4. After jumping to the exception service routine start address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 159 of 3088 Section 6 Exception Handling 6.6.6 SH7268 Group, SH7269 Group FPU Exceptions An FPU exception handling is generated when the V, Z, O, U or I bit in the FPU exception enable field (Enable) of the floating point status/control register (FPSCR) is set. This indicates the occurrence of an invalid operation exception defined by the IEEE standard 754, a division-by-zero exception, overflow (in the case of an instruction for which this is possible), underflow (in the case of an instruction for which this is possible), or inexact exception (in the case of an instruction for which this is possible). The floating point operation instructions that may cause an FPU exception handling are FADD, FSUB, FMUL, FDIV, FMAC, FCMP/EQ, FCMP/GT, FLOAT, FTRC, FCNVDS, FCNVSD, and FSQRT. An FPU exception handling is generated only when the corresponding FPU exception enable bit (Enable) is set. When the FPU detects an exception source in floating point operation, FPU operation is halted and generation of an FPU exception handling is reported to the CPU. When exception handling is started, the CPU operations are as follows. 1. The start address of the exception service routine which corresponds to the FPU exception handling that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the last executed instruction. 4. After jumping to the exception service routine start address fetched from the exception handling vector table, program execution starts. This jump is not a delayed branch. The FPU exception flag field (Flag) of FPSCR is always updated regardless of whether or not an FPU exception handling has been accepted, and remains set until explicitly cleared by the user through an instruction. The FPU exception source field (Cause) of FPSCR changes each time a floating point operation instruction is executed. When the V bit in the FPU exception enable field (Enable) of FPSCR is set and the QIS bit in FPSCR is also set, FPU exception handling is generated when qNAN or is input to a floating point operation instruction source.

When this happens, it will be accepted when an instruction that can accept the exception is decoded.

If it is not, an address error will occur when the stack is accessed during exception handling. 6.9.2 Value of Vector Base Register (VBR) The value of the vector base register must always be a multiple of four. If it is not, an address error will occur when the stack is accessed during exception handling. 6.9.3 Address Errors Caused by Stacking of Address Error Exception Handling When the stack pointer is not a multiple of four, an address error will occur during stacking of the exception handling (interrupts, etc.) and address error exception handling will start up as soon as the first exception handling is ended. Address errors will then also occur in the stacking for this address error exception handling. To ensure that address error exception handling does not go into an endless loop, no address errors are accepted at that point. This allows program control to be shifted to the address error exception service routine and enables error processing. When an address error occurs during exception handling stacking, the stacking bus cycle (write) is executed. During stacking of the status register (SR) and program counter (PC), the SP is decremented by 4 for both, so the value of SP will not be a multiple of four after the stacking either. The address value output during stacking is the SP value, so the address where the error occurred is itself output. This means the write data stacked will be undefined. 6.9.4 Interrupt Control via Modification of Interrupt Mask Bits When enabling interrupts by changing the interrupt mask bits (I3 to I0) of the status register (SR) using the LDC or LDC.L instructions, interrupts might not be accepted during the execution of the 5 instructions immediately after the LDC/LDC.L instruction. Therefore, when enabling/disabling interrupts by changing the interrupt mask bits (I3 to I0) of the status register (SR) using LDC/LDC.L instructions, please place at least 5 instructions between the interrupt-enable instruction and the interrupt-disable instruction.

So, if the exception handling is generated * Ex. 1: when the exception handling vector table is stored in an external address space, but the settings of bus state controller and general I/O ports to access the external address space have been not completed yet, or * Ex. 2: when the exception handling vector table is stored in the on-chip RAM, but the vector base register (VBR) has been not changed to the on-chip RAM address yet, the CPU fetches an unintended value as the execution start address, and starts executing programs from unintended address. (1) Manual Reset Before the settings necessary to access the external CS0 space are completed, the manual reset should not be generated. When a manual reset is generated, the CPU fetches the execution start address from the location at the offset for the manual reset (H'00000008) in the vector table, that is, always from the external CS0 space. Additionally, in the case that no memory is connected to the external CS0 space in boot modes 2 to 5, the manual reset should not be generated. (2) NMI Interrupt Before the exception handling vector table is stored in a memory and the settings necessary to access the memory are completed, the settings to permit the interrupts should not be done. Specially in boot modes 2 to 5, the VBR is kept as the initial value H'00000000 in the period of the boot operation (before the transfer of the loader program is completed and the CPU jumps to the on-chip high-speed RAM). Before the VBR is changed or the settings necessary to access the external address space are completed in the loader program, the settings to permit the interrupts should not be done. (3) Interrupts Other Than NMI Before the exception handling vector table is stored in a memory and the settings necessary to access the memory are completed, the settings to permit the interrupts should not be done.

The interrupt controller registers set the order of priority of each interrupt, allowing the user to process interrupt requests according to the user-set priority. 7.1 Features * 16 levels of interrupt priority can be set. By setting the 24 interrupt priority registers, the priorities of IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts can be selected from 16 levels for request sources. * NMI noise canceler function An NMI input-level bit indicates the NMI pin state. By reading this bit in the interrupt exception service routine, the pin state can be checked, enabling it to be used as the noise canceler function. * Register banks This LSI has register banks that enable register saving and restoration required in the interrupt processing to be performed at high speed.

R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 183 of 3088 Section 7 Interrupt Controller 7.4 SH7268 Group, SH7269 Group Interrupt Sources There are six types of interrupt sources: NMI, user break, user debugging interface, IRQ, PINT, and on-chip peripheral modules. Each interrupt has a priority level (0 to 16), with 0 the lowest and 16 the highest. When set to level 0, that interrupt is masked at all times. 7.4.1 NMI Interrupt The NMI interrupt has a priority level of 16 and is accepted at all times when the NMI mask bit (NMIM) in interrupt control register 0 (ICR0) is enabled. NMI interrupt requests are edgedetected, and the NMI edge select bit (NMIE) in ICR0 selects whether the rising edge or falling edge is detected. Though the priority level of the NMI interrupt is 16, the NMI interrupt exception handling sets the interrupt mask level bits (I3 to I0) in the status register (SR) to level 15. When the NMIM bit in ICR0 is set to 1 (NMI interrupt request is masked), the NMI interrupt is not generated, however the NMI edge corresponding to NMIE bit of ICR0 is detected and the NMI interrupt request is retained until the interrupt request is accepted. The status of the interrupt request can be checked by reading the NMI interrupt request bit (NMIF) in the ICR0. If 0 is written to the NMIM bit (NMI interrupt request is enabled) when the NMIF bit is set to 1, the NMI interrupt request that is retained is accepted. Once the NMIM bit is set to 0 (NMI interrupt request is enabled), the NMIM bit cannot be set to 1 again, because only 0 can be written to the NMIM bit. When the NME bit is changed, the NMI interrupt request that is retained is cleared. When canceling software standby mode by the NMI interrupt, set the NMIM bit to 0 to enable the NMI interrupt request after confirming that the NMI interrupt request has been cleared in the NMIF. If software standby mode is entered when the NMIM bit is 1 (NMI interrupt request is masked), the NMI interrupt cannot cancel software standby mode. In this case, the NMI edge cannot be detected in software standby mode and the NMI interrupt is not generated even if software standby mode is canceled by cancel source other than NMI. When the NMI pin keeps level (low level after the falling edge or high level after the rising edge) in software standby mode until software standby mode is canceled by cancel source other than NMI (until the clock is initiated after the oscillation settling), that edge of the NMI in software standby mode can be detected. When deep standby mode is entered, deep standby mode is canceled by the NMI interrupt regardless of the NMI mask bit setting. NMIM bit is initialized by a power-on reset after canceling deep standby mode. When a sleep instruction is to be executed after 0 has been written to the NMIM bit (enabling the NMI), read the value of the NMIM bit before executing the sleep instruction. Page 184 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 7.4.2 Section 7 Interrupt Controller User Break Interrupt A user break interrupt which occurs when a break condition set in the user break controller matches has a priority level of 15. The user break interrupt exception handling sets the I3 to I0 bits in SR to level 15. For user break interrupts, see section 8, User Break Controller. 7.4.3 User Debugging Interface Interrupt The user debugging interface interrupt has a priority level of 15, and occurs at serial input of a user debugging interface interrupt instruction. User debugging interface interrupt requests are edge-detected and retained until they are accepted. The user debugging interface interrupt exception handling sets the I3 to I0 bits in SR to level 15. For user debugging interface interrupts, see section 50, User Debugging Interface. 7.4.4 IRQ Interrupts IRQ interrupts are input from pins IRQ7 to IRQ0. For the IRQ interrupts, low-level, falling-edge, rising-edge, or both-edge detection can be selected individually for each pin by the IRQ sense select bits (IRQ71S to IRQ01S and IRQ70S to IRQ00S) in interrupt control register 1 (ICR1). The priority level can be set individually in a range from 0 to 15 for each pin by interrupt priority registers 01 and 02 (IPR01 and IPR02). When using low-level sensing for IRQ interrupts, an interrupt request signal is sent to the interrupt controller while the IRQ7 to IRQ0 pins are low. An interrupt request signal is stopped being sent to the interrupt controller when the IRQ7 to IRQ0 pins are driven high. The status of the interrupt requests can be checked by reading the IRQ interrupt request bits (IRQ7F to IRQ0F) in the IRQ interrupt request register (IRQRR). When using edge-sensing for IRQ interrupts, an interrupt request is detected due to change of the IRQ7 to IRQ0 pin states, and an interrupt request signal is sent to the interrupt controller. The result of IRQ interrupt request detection is retained until that interrupt request is accepted. Whether IRQ interrupt requests have been detected or not can be checked by reading the IRQ7F to IRQ0F bits in IRQRR. Writing 0 to these bits after reading them as 1 clears the result of IRQ interrupt request detection. The IRQ interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the accepted IRQ interrupt. When returning from IRQ interrupt exception service routine, execute the RTE instruction after confirming that the interrupt request has been cleared by the IRQ interrupt request register (IRQRR) so as not to accidentally receive the interrupt request again. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 185 of 3088 Section 7 Interrupt Controller 7.4.5 SH7268 Group, SH7269 Group PINT Interrupts PINT interrupts are input from pins PINT7 to PINT0. Input of the interrupt requests is enabled by the PINT enable bits (PINT7E to PINT0E) in the PINT interrupt enable register (PINTER). For the PINT7 to PINT0 interrupts, low-level or high-level detection can be selected individually for each pin by the PINT sense select bits (PINT7S to PINT0S) in interrupt control register 2 (ICR2). A single priority level in a range from 0 to 15 can be set for all PINT7 to PINT0 interrupts by bits 15 to 12 in interrupt priority register 05 (IPR05). When using low-level sensing for the PINT7 to PINT0 interrupts, an interrupt request signal is sent to the interrupt controller while the PINT7 to PINT0 pins are low. An interrupt request signal is stopped being sent to the interrupt controller when the PINT7 to PINT0 pins are driven high. The status of the interrupt requests can be checked by reading the PINT interrupt request bits (PINT7R to PINT0R) in the PINT interrupt request register (PIRR). The above description also applies to when using high-level sensing, except for the polarity being reversed. The PINT interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the PINT interrupt. When returning from IRQ interrupt exception service routine, execute the RTE instruction after confirming that the interrupt request has been cleared by the PINT interrupt request register (PIRR) so as not to accidentally receive the interrupt request again.

A priority level in a range from 0 to 15 can be set for each module by interrupt priority registers 05 to 26 (IPR05 to IPR26). The on-chip peripheral module interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the accepted on-chip peripheral module interrupt. Page 188 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 7.5 Section 7 Interrupt Controller Interrupt Exception Handling Vector Table and Priority Table 7.4 lists interrupt sources and their vector numbers, vector table address offsets, and interrupt priorities. Each interrupt source is allocated a different vector number and vector table address offset. Vector table addresses are calculated from the vector numbers and vector table address offsets. In interrupt exception handling, the interrupt exception service routine start address is fetched from the vector table indicated by the vector table address. For details of calculation of the vector table address, see table 6.4 in section 6, Exception Handling. The priorities of IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts can be set freely between 0 and 15 for each pin or module by setting interrupt priority registers 01, 02, and 05 to 26 (IPR01, IPR02, and IPR05 to IPR26). However, if two or more interrupts specified by the same IPR among IPR05 to IPR26 occur, the priorities are defined as shown in the IPR setting unit internal priority of table 7.4, and the priorities cannot be changed. A power-on reset assigns priority level 0 to IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts. If the same priority level is assigned to two or more interrupt sources and interrupts from those sources occur simultaneously, they are processed by the default priorities indicated in table 7.4.

operations is described below. Figure 7.2 shows the operation flow. 1. The interrupt request sources send interrupt request signals to the interrupt controller. 2. The interrupt controller selects the highest-priority interrupt from the interrupt requests sent, following the priority levels set in interrupt priority registers 01, 02, and 05 to 26 (IPR01, IPR02, and IPR05 to IPR26). Lower priority interrupts are ignored*. If two of these interrupts have the same priority level or if multiple interrupts occur within a single IPR, the interrupt with the highest priority is selected, according to the default priority and IPR setting unit internal priority shown in table 7.4. 3. The priority level of the interrupt selected by the interrupt controller is compared with the interrupt level mask bits (I3 to I0) in the status register (SR) of the CPU. If the interrupt request priority level is equal to or less than the level set in bits I3 to I0, the interrupt request is ignored. If the interrupt request priority level is higher than the level in bits I3 to I0, the interrupt controller accepts the interrupt and sends an interrupt request signal to the CPU. 4. The CPU detects the interrupt request sent from the interrupt controller when the CPU decodes the instruction to be executed. Instead of executing the decoded instruction, the CPU starts interrupt exception handling (figure 7.4). 5. The interrupt exception service routine start address is fetched from the exception handling vector table corresponding to the accepted interrupt. 6. The status register (SR) is saved onto the stack, and the priority level of the accepted interrupt is copied to bits I3 to I0 in SR. 7. The program counter (PC) is saved onto the stack. 8. The CPU jumps to the fetched interrupt exception service routine start address and starts executing the program. The jump that occurs is not a delayed branch. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 205 of 3088 Section 7 Interrupt Controller SH7268 Group, SH7269 Group Notes: The interrupt source flag should be cleared in the interrupt handler. After clearing the interrupt source flag, "time from occurrence of interrupt request until interrupt controller identifies priority, compares it with mask bits in SR, and sends interrupt request signal to CPU" shown in table 7.5 is required before the interrupt source sent to the CPU is actually cancelled. To ensure that an interrupt request that should have been cleared is not inadvertently accepted again, read the interrupt source flag after it has been cleared, and then execute an RTE instruction. * Interrupt requests that are designated as edge-sensing are held pending until the interrupt requests are accepted. IRQ interrupts, however, can be cancelled by accessing the IRQ interrupt request register (IRQRR). For details, see section 7.4.4, IRQ Interrupts.

The interrupt processing operations differ in the cases when banking is disabled, when banking is enabled without register bank overflow, and when banking is enabled with register bank overflow. Figures 7.4 and 7.5 show examples of pipeline operation when banking is disabled. Figures 7.6 and 7.7 show examples of pipeline operation when banking is enabled without register bank overflow.

(2) Input/Output of Banks This LSI has fifteen register banks, bank 0 to bank 14. Register banks are stacked in first-in lastout (FILO) sequence. Saving takes place in order, beginning from bank 0, and restoration takes place in the reverse order, beginning from the last bank saved to. 7.8.2 (1) Bank Save and Restore Operations Saving to Bank Figure 7.11 shows register bank save operations. The following operations are performed when an interrupt for which usage of register banks is allowed is accepted by the CPU: a. Assume that the bank number bit value in the bank number register (IBNR), BN, is i before the interrupt is generated. b. The contents of registers R0 to R14, GBR, MACH, MACL, and PR, and the interrupt vector table address offset (VTO) of the accepted interrupt are saved in the bank indicated by BN, bank i. c.

After restoring data from the register banks with the RESBANK instruction at the end of the interrupt exception service routine, execute the RTE instruction to return from interrupt exception service routine. Page 218 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 7.8.3 Section 7 Interrupt Controller Save and Restore Operations after Saving to All Banks If an interrupt occurs and usage of the register banks is enabled for the interrupt accepted by the CPU in a state where saving has been performed to all register banks, automatic saving to the stack is performed instead of register bank saving if the BOVE bit in the bank number register (IBNR) is cleared to 0. If the BOVE bit in IBNR is set to 1, register bank overflow exception occurs and data is not saved to the stack. Save and restore operations when using the stack are as follows: (1) Saving to Stack 1. The status register (SR) and program counter (PC) are saved to the stack during interrupt exception handling. 2. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are saved to the stack. The registers are saved to the stack in the order of MACL, MACH, GBR, PR, R14, R13, ..., R1, and R0. 3. The register bank overflow bit (BO) in SR is set to 1. 4. The bank number bit (BN) value in the bank number register (IBNR) remains set to the maximum value of 15. (2) Restoration from Stack When the RESBANK (restore from register bank) instruction is executed with the register bank overflow bit (BO) in SR set to 1, the CPU operates as follows: 1. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are restored from the stack. The registers are restored from the stack in the order of R0, R1, ..., R13, R14, PR, GBR, MACH, and MACL. 2. The bank number bit (BN) value in the bank number register (IBNR) remains set to the maximum value of 15. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 219 of 3088 Section 7 Interrupt Controller 7.8.4 SH7268 Group, SH7269 Group Register Bank Exception There are two register bank exceptions (register bank errors): register bank overflow and register bank underflow. (1) Register Bank Overflow This exception occurs if, after data has been saved to all of the register banks, an interrupt for which register bank use is allowed is accepted by the CPU, and the BOVE bit in the bank number register (IBNR) is set to 1. In this case, the bank number bit (BN) value in the bank number register (IBNR) remains set to the bank count of 15 and saving is not performed to the register bank. (2) Register Bank Underflow This exception occurs if the RESBANK (restore from register bank) instruction is executed when no data has been saved to the register banks. In this case, the values of R0 to R14, GBR, MACH, MACL, and PR do not change. In addition, the bank number bit (BN) value in the bank number register (IBNR) remains set to 0. 7.8.5 Register Bank Error Exception Handling When a register bank error occurs, register bank error exception handling starts. When this happens, the CPU operates as follows: 1. The exception service routine start address which corresponds to the register bank error that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the last executed instruction for a register bank overflow, and the start address of the executed RESBANK instruction for a register bank underflow. To prevent multiple interrupts from occurring at a register bank overflow, the interrupt priority level that caused the register bank overflow is written to the interrupt mask level bits (I3 to I0) of the status register (SR). 4. Program execution starts from the exception service routine start address.

Interrupt sources that are designated to activate the direct memory access controller are masked without being input to the interrupt controller. The mask condition is as follows: Mask condition = DME * (DE0 * interrupt source select 0 + DE1 * interrupt source select 1 + DE2 * interrupt source select 2 + DE3 * interrupt source select 3 + DE4 * interrupt source select 4 + DE5 * interrupt source select 5 + DE6 * interrupt source select 6 + DE7 * interrupt source select 7 + DE8 * interrupt source select 8 + DE9 * interrupt source select 9 + DE10 * interrupt source select 10 + DE11 * interrupt source select 11 + DE12 * interrupt source select 12 + DE13 * interrupt source select 13 + DE14 * interrupt source select 14 + DE15 * interrupt source select 15) Figure 7.13 shows a block diagram of interrupt control. Here, DME is bit 0 in DMAOR of the direct memory access controller, and DEn (n = 0 to 15) is bit 0 in CHCR_0 to CHCR_15 of the direct memory access controller. For details, see section 11, Direct Memory Access Controller.

If, direct memory access controller activating sources are selected, clear the DE bit to 0 for the relevant channel of the direct memory access controller. 2. When interrupts occur, interrupt requests are sent to the CPU. 3. The CPU clears the interrupt source and performs the necessary processing in the interrupt exception service routine. 7.9.2 Handling Interrupt Request Signals as Sources for Activating Direct Memory Access Controller but Not CPU Interrupt 1. Select direct memory access controller activating sources and set both the DE and DME bits to 1. This masks CPU interrupt sources regardless of the interrupt priority register settings. 2. Activating sources are applied to the direct memory access controller when interrupts occur. 3. The direct memory access controller clears the interrupt sources when starting transfer. Page 222 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 7.10 Usage Note 7.10.1 Timing to Clear an Interrupt Source Section 7 Interrupt Controller The interrupt source flags should be cleared in the interrupt exception service routine. After clearing the interrupt source flag, "time from occurrence of interrupt request until interrupt controller identifies priority, compares it with mask bits in SR, and sends interrupt request signal to CPU" shown in table 7.5 is required before the interrupt source sent to the CPU is actually cancelled. To ensure that an interrupt request that should have been cleared is not inadvertently accepted again, read* the interrupt source flag after it has been cleared, and then execute an RTE instruction. Note: * When clearing the USB 2.0 host/function module interrupt source flag, read the flag three times after clearing it.

These functions make it easy to design an effective self-monitoring debugger, enabling the chip to debug programs without using an in-circuit emulator. Instruction fetch or data read/write (bus cycle (CPU or direct memory access controller) selection in the case of data read/write), data size, data contents, address value, and stop timing in the case of instruction fetch are break conditions that can be set in this module. Since this LSI uses a Harvard architecture, instruction fetch on the CPU bus (C bus) is performed by issuing bus cycles on the instruction fetch bus (F bus), and data access on the C bus is performed by issuing bus cycles on the memory access bus (M bus). The internal bus (I bus) consists of the internal CPU bus, on which the CPU issues bus cycles, and the internal DMA bus, on which the direct memory access controller issues bus cycles. This module monitors the C bus and I bus. 8.1 Features 1. The following break comparison conditions can be set. Number of break channels: two channels (channels 0 and 1) User break can be requested as the independent condition on channels 0 and 1. Address Comparison of the 32-bit address is maskable in 1-bit units. One of the four address buses (F address bus (FAB), M address bus (MAB), internal CPU address bus (ICAB), and internal DMA address bus (IDAB)) can be selected. Data Comparison of the 32-bit data is maskable in 1-bit units. One of the three data buses (M data bus (MDB), internal CPU data bus (ICDB), and internal DMA data bus (IDDB)) can be selected. Bus selection when I bus is selected Internal CPU bus or internal DMA bus Bus cycle Instruction fetch (only when C bus is selected) or data access Read/write Operand size Byte, word, and longword 2. In an instruction fetch cycle, it can be selected whether the start of user break interrupt exception processing is set before or after an instruction is executed. 3. When a break condition is satisfied, a trigger signal is output from the UBCTRG pin.

Page 238 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 8.4 Operation 8.4.1 Flow of the User Break Operation Section 8 User Break Controller The flow from setting of break conditions to user break interrupt exception handling is described below: 1. The break address is set in a break address register (BAR). The masked address bits are set in a break address mask register (BAMR). The break data is set in the break data register (BDR). The masked data bits are set in the break data mask register (BDMR). The bus break conditions are set in the break bus cycle register (BBR). Three control bit groups of BBR (C bus cycle/I bus cycle select, instruction fetch/data access select, and read/write select) are each set. No user break will be generated if even one of these groups is set to 00. The relevant break control conditions are set in the bits of the break control register (BRCR). Make sure to set all registers related to breaks before setting BBR, and branch after reading from the last written register. The newly written register values become valid from the instruction at the branch destination. 2. In the case where the break conditions are satisfied and the user break interrupt request is enabled, this module sends a user break interrupt request to the interrupt controller sets the C bus condition match flag (SCMFC) or I bus condition match flag (SCMFD) for the appropriate channel, and outputs a pulse to the UBCTRG pin with the width set by the CKS[1:0] bits. Setting the UBID bit in BBR to 1 enables external monitoring of the trigger output without requesting user break interrupts. 3. On receiving a user break interrupt request signal, the interrupt controller determines its priority. Since the user break interrupt has a priority level of 15, it is accepted when the priority level set in the interrupt mask level bits (I3 to I0) of the status register (SR) is 14 or lower. If the I3 to I0 bits are set to a priority level of 15, the user break interrupt is not accepted, but the conditions are checked, and condition match flags are set if the conditions match. For details on ascertaining the priority, see section 7, Interrupt Controller. 4. Condition match flags (SCMFC and SCMFD) can be used to check which condition has been satisfied. Clear the condition match flags during the user break interrupt exception processing routine. The interrupt occurs again if this operation is not performed. 5. There is a chance that the break set in channel 0 and the break set in channel 1 occur around the same time. In this case, there will be only one user break request to the interrupt controller but these two break channel match flags may both be set. 6. When selecting the I bus as the break condition, note as follows: Whether or not an access issued on the C bus by the CPU is issued on the internal CPU bus depends on the cache settings. Regarding the I bus operation under cache conditions, see table 9.8 in section 9, Cache. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 239 of 3088 Section 8 User Break Controller SH7268 Group, SH7269 Group When a break condition is specified for the I bus, only the data access cycle is monitored. The instruction fetch cycle (including the cache renewal cycle) is not monitored. Only data access cycles are issued for the internal DMA bus cycles. If a break condition is specified for the I bus, even when the condition matches in an internal CPU bus cycle resulting from an instruction executed by the CPU, at which instruction the user break interrupt request is to be accepted cannot be clearly defined. 8.4.2 Break on Instruction Fetch Cycle 1. When C bus/instruction fetch/read/word or longword is set in the break bus cycle register (BBR), the break condition is the FAB bus instruction fetch cycle. Whether a start of user break interrupt exception processing is set before or after the execution of the instruction can then be selected with the PCB0 or PCB1 bit of the break control register (BRCR) for the appropriate channel. If an instruction fetch cycle is set as a break condition, clear BA0 bit in the break address register (BAR) to 0. A break cannot be generated as long as this bit is set to 1. 2. A break for instruction fetch which is set as a break before instruction execution occurs when it is confirmed that the instruction has been fetched and will be executed. This means a break does not occur for instructions fetched by overrun (instructions fetched at a branch or during an interrupt transition, but not to be executed). When this kind of break is set for the delay slot of a delayed branch instruction, the user break interrupt request is not received until the execution of the first instruction at the branch destination. Note: If a branch does not occur at a delayed branch instruction, the subsequent instruction is not recognized as a delay slot. 3. When setting a break condition for break after instruction execution, the instruction set with the break condition is executed and then the break is generated prior to execution of the next instruction. As with pre-execution breaks, a break does not occur with overrun fetch instructions. When this kind of break is set for a delayed branch instruction and its delay slot, the user break interrupt request is not received until the first instruction at the branch destination. 4. When an instruction fetch cycle is set, the break data register (BDR) is ignored. Therefore, break data cannot be set for the break of the instruction fetch cycle. 5. If the I bus is set for a break of an instruction fetch cycle, the setting is invalidated. Page 240 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 8.4.3 Section 8 User Break Controller Break on Data Access Cycle 1. If the C bus is specified as a break condition for data access break, condition comparison is performed for the addresses (and data) accessed by the executed instructions, and a break occurs if the condition is satisfied. If the I bus is specified as a break condition, condition comparison is performed for the addresses (and data) of the data access cycles on the bus specified by the I bus select bits, and a break occurs if the condition is satisfied. For details on the CPU bus cycles issued on the internal CPU bus, see 6 in section 8.4.1, Flow of the User Break Operation. 2. The relationship between the data access cycle address and the comparison condition for each operand size is listed in table 8.3. Table 8.3 Data Access Cycle Addresses and Operand Size Comparison Conditions Access Size Address Compared Longword Compares break address register bits 31 to 2 to address bus bits 31 to 2 Word Compares break address register bits 31 to 1 to address bus bits 31 to 1 Byte Compares break address register bits 31 to 0 to address bus bits 31 to 0 This means that when address H'00001003 is set in the break address register (BAR), for example, the bus cycle in which the break condition is satisfied is as follows (where other conditions are met). Longword access at H'00001000 Word access at H'00001002 Byte access at H'00001003 3. When the data value is included in the break conditions: When the data value is included in the break conditions, either longword, word, or byte is specified as the operand size in the break bus cycle register (BBR). When data values are included in break conditions, a break is generated when the address conditions and data conditions both match. To specify byte data for this case, set the same data in the four bytes at bits 31 to 24, 23 to 16, 15 to 8, and 7 to 0 of the break data register (BDR) and break data mask register (BDMR). To specify word data for this case, set the same data in the two words at bits 31 to 16 and 15 to 0. 4. Access by a PREF instruction is handled as read access in longword units without access data. Therefore, if including the value of the data bus when a PREF instruction is specified as a break condition, a break will not occur. 5. If the data access cycle is selected, the instruction at which the break will occur cannot be determined.

If the C bus (FAB)/instruction fetch cycle is specified as a break condition, the instruction at which the break should occur can be uniquely determined. If the C bus/data access cycle or I bus/data access cycle is specified as a break condition, the instruction at which the break should occur cannot be uniquely determined. 1. When C bus (FAB)/instruction fetch (before instruction execution) is specified as a break condition: The address of the instruction that matched the break condition is saved to the stack. The instruction that matched the condition is not executed, and the break occurs before it. However when a delay slot instruction matches the condition, the instruction is executed, and the branch destination address is saved to the stack. 2. When C bus (FAB)/instruction fetch (after instruction execution) is specified as a break condition: The address of the instruction following the instruction that matched the break condition is saved to the stack. The instruction that matches the condition is executed, and the break occurs before the next instruction is executed. However when a delayed branch instruction or delay slot matches the condition, the instruction is executed, and the branch destination address is saved to the stack. 3.

The CPU can read from or write to this module registers via the internal CPU bus. Accordingly, during the period from executing an instruction to rewrite this module register till the new value is actually rewritten, the desired break may not occur. In order to know the timing when this module register is changed, read from the last written register. Instructions after then are valid for the newly written register value. 2. This module cannot monitor the C bus, internal CPU, and internal DMA bus cycles in the same channel. 3. When a user break interrupt request and another exception source occur at the same instruction, which has higher priority is determined according to the priority levels defined in table 6.1 in section 6, Exception Handling. If an exception source with higher priority occurs, the user break interrupt request is not received. 4. Note the following when a break occurs in a delay slot. If a pre-execution break is set at a delay slot instruction, the user break interrupt request is not received immediately before execution of the branch destination. 5. User breaks are disabled during module standby mode. Do not read from or write to this module registers during module standby mode; the values are not guaranteed. 6. Do not set an address within an interrupt exception handling routine whose interrupt priority level is at least 15 (including user break interrupts) as a break address. 7. Do not set break after instruction execution for the SLEEP instruction or for the delayed branch instruction where the SLEEP instruction is placed at its delay slot. 8. When setting a break for a 32-bit instruction, set the address where the upper 16 bits are placed. If the address of the lower 16 bits is set and a break before instruction execution is set as a break condition, the break is handled as a break after instruction execution. 9. Do not set a user break before instruction execution for the instruction following the DIVU or DIVS instruction. If a user break before instruction execution is set for the instruction following the DIVU or DIVS instruction and an exception or interrupt occurs during execution of the DIVU or DIVS instruction, a user break occurs before instruction execution even though execution of the DIVU or DIVS instruction is halted.

It is composed of four ways (banks), each of which is divided into an address section and a data section. In each way, each of the address and data sections is divided into 128 entries. The data section of the entry is called a line. Each line consists of 16 bytes (4 bytes x 4). The data capacity per way is 2 Kbytes (16 bytes x 128 entries), with a total of 8 Kbytes in the cache as a whole (4 ways). Figure 9.1 shows the operand cache structure. The instruction cache structure is the same as the operand cache structure except for not having the U bit.

When the V bit is 1, data is valid; when 0, data is not valid. The U bit (only for operand cache) indicates whether the entry has been written to in write-back mode. When the U bit is 1, the entry has been written to; when 0, it has not. The tag address holds the physical address used in the access to external memory or large-capacity on-chip RAM. It consists of 21 bits (address bits 31 to 11) used for comparison during cache searches. In this LSI, the addresses of the cache-enabled space are H'00000000 to H'1FFFFFFF (see section 10, Bus State Controller), and therefore the upper three bits of the tag address are cleared to 0. The V and U bits are initialized to 0 by a power-on reset but not initialized by a manual reset or in software standby mode. The tag address is not initialized by a power-on reset or manual reset or in software standby mode. (2) Data Array Holds a 16-byte instruction or data. Entries are registered in the cache in line units (16 bytes). The data array is not initialized by a power-on reset or manual reset or in software standby mode. Page 248 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (3) Section 9 Cache LRU With the 4-way set associative system, up to four instructions or data with the same entry address can be registered in the cache. When an entry is registered, LRU shows which of the four ways it is recorded in. There are six LRU bits, controlled by hardware. A least-recently-used (LRU) algorithm is used to select the way that has been least recently accessed. Six LRU bits indicate the way to be replaced in case of a cache miss. The relationship between LRU and way replacement is shown in table 9.1 when the cache lock function (only for operand cache) is not used (concerning the case where the cache lock function is used, see section 9.2.2, Cache Control Register 2 (CCR2)). If a bit pattern other than those listed in table 9.1 is set in the LRU bits by software, the cache will not function correctly. When modifying the LRU bits by software, set one of the patterns listed in table 9.1. The LRU bits are initialized to B'000000 by a power-on reset but not initialized by a manual reset or in software standby mode.

In cache locking mode, the lock enable bit (the LE bit) in CCR2 is set to 1. In non-cache-locking mode, the cache locking function is invalid. When a cache miss occurs in cache locking mode by executing the prefetch instruction (PREF @Rn), the line of data pointed to by Rn is loaded into the cache according to bits 9 and 8 (the W3LOAD and W3LOCK bits) and bits 1 and 0 (the W2LOAD and W2LOCK bits) in CCR2. The relationship between the setting of each bit and a way, to be replaced when the prefetch instruction is executed, are listed in table 9.3. On the other hand, when the prefetch instruction is executed and a cache hit occurs, new data is not fetched and the entry which is already enabled is held. For example, when the prefetch instruction is executed with W3LOAD = 1 and W3LOCK = 1 specified in cache locking mode while one-line data already exists in way 0 which is specified by Rn, a cache hit occurs and data is not fetched to way 3. In the cache access other than the prefetch instruction in cache locking mode, ways to be replaced by bits W3LOCK and W2LOCK are restricted. The relationship between the setting of each bit in CCR2 and ways to be replaced are listed in table 9.4. Programs that change the contents of CCR2 should be placed in a cache-disabled space, and a cache-enabled space should be accessed after reading the contents of CCR2.

Operations for the instruction cache are similar to those for the operand cache except for the address array not having the U bit, and there being no prefetch operation or write operation, or a write-back buffer. 9.3.1 Searching Cache If the operand cache is enabled (OCE bit in CCR1 is 1), whenever data in a cache-enabled area is accessed, the cache will be searched to see if the desired data is in the cache. Figure 9.2 illustrates the method by which the cache is searched. Entries are selected using bits 10 to 4 of the address used to access memory and the tag address of that entry is read. At this time, the upper three bits of the tag address are always cleared to 0. Bits 31 to 11 of the address used to access memory are compared with the read tag address. The address comparison uses all four ways. When the comparison shows a match and the selected entry is valid (V = 1), a cache hit occurs. When the comparison does not show a match or the selected entry is not valid (V = 0), a cache miss occurs. Figure 9.2 shows a hit on way 1.

LRU is updated so that the hit way is the latest. (2) Read Miss An internal bus cycle starts and the entry is updated. The way replaced follows table 9.4. Entries are updated in 16-byte units. When the desired data that caused the miss is loaded from the external memory or the large-capacity on-chip RAM to the cache, the data is transferred to the CPU in parallel with being loaded to the cache. When it is loaded in the cache, the V bit is set to 1, and LRU is updated so that the replaced way becomes the latest. In operand cache, the U bit is additionally cleared to 0. When the U bit of the entry to be replaced by updating the entry in writeback mode is 1, the cache update cycle starts after the entry is transferred to the write-back buffer. After the cache completes its update cycle, the write-back buffer writes the entry back to the memory. The write-back unit is 16 bytes. Cache update operation and write-back operation to the memory are performed in wrap-around mode. When the lower four bits of the address of readmiss data are H'4, for example, cache update operation and write-back operation to the memory are performed in the following order of the lower 4-bit value of address: H'4 H'8 H'C H'0. 9.3.3 (1) Prefetch Operation (Only for Operand Cache) Prefetch Hit LRU is updated so that the hit way becomes the latest. The contents in other caches are not modified. No data is transferred to the CPU. (2) Prefetch Miss No data is transferred to the CPU. The way to be replaced follows table 9.3. Other operations are the same as those in the case of read miss. Page 258 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 9.3.4 (1) Section 9 Cache Write Operation (Only for Operand Cache) Write Hit In a write access in write-back mode, the data is written to the cache and no write cycle to the external memory or the large-capacity on-chip RAM is issued. The U bit of the entry written is set to 1 and LRU is updated so that the hit way becomes the latest. In write-through mode, the data is written to the cache and a write cycle to the external memory or the large-capacity on-chip RAM is issued. The U bit of the written entry is not updated and LRU is updated so that the replaced way becomes the latest. (2) Write Miss In write-back mode, an internal bus cycle starts when a write miss occurs, and the entry is updated. The way to be replaced follows table 9.4. When the U bit of the entry to be replaced is 1, the cache update cycle starts after the entry is transferred to the write-back buffer. Data is written to the cache, the U bit is set to 1, and the V bit is set to 1. LRU is updated so that the replaced way becomes the latest. After the cache completes its update cycle, the write-back buffer writes the entry back to the memory. The write-back unit is 16 bytes. Cache update operation and write-back operation to the memory are performed in wrap-around mode. When the lower four bits of the address of write-miss data are H'4, for example, cache update operation and write-back operation to the memory are performed in the following order of the lower 4-bit value of address: H'4 H'8 H'C H'0. In write-through mode, no write to cache occurs in a write miss; the write is only to the external memory or the large-capacity on-chip RAM. 9.3.5 Write-Back Buffer (Only for Operand Cache) When the U bit of the entry to be replaced in the write-back mode is 1, it must be written back to the external memory or the large-capacity on-chip RAM. To increase performance, the entry to be replaced is first transferred to the write-back buffer and fetching of new entries to the cache takes priority over writing back to the external memory. After the cache completes to fetch the new entry, the write-back buffer writes the entry back to the external memory or the large-capacity onchip RAM. During the write-back cycles, the cache can be accessed. The write-back buffer can hold one line of cache data (16 bytes) and its physical address. Figure 9.3 shows the configuration of the write-back buffer.

When memory shared by this LSI and another device is mapped in the cache-enabled space, operate the memory-mapped cache to invalidate and write back as required. The same operation should be performed for the memory shared by the CPU and the direct memory access controller in this LSI. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 261 of 3088 Section 9 Cache 9.4 SH7268 Group, SH7269 Group Memory-Mapped Cache To allow software management of the cache, cache contents can be read and written by means of MOV instructions. The instruction cache address array is mapped onto addresses H'F0000000 to H'F07FFFFF, and the data array onto addresses H'F1000000 to H'F17FFFFF. The operand cache address array is mapped onto addresses H'F0800000 to H'F0FFFFFF, and the data array onto addresses H'F1800000 to H'F1FFFFFF. Only longword can be used as the access size for the address array and data array, and instruction fetches cannot be performed. 9.4.1 Address Array To access an address array, the 32-bit address field (for read/write accesses) and 32-bit data field (for write accesses) must be specified. In the address field, specify the entry address for selecting the entry, the W bit for selecting the way, and the A bit for specifying the existence of associative operation. In the W bit, B'00 is way 0, B'01 is way 1, B'10 is way 2, and B'11 is way 3. Since the access size of the address array is fixed at longword, specify B'00 for bits 1 and 0 of the address. The tag address, LRU bits, U bit (only for operand cache), and V bit are specified as data. Always specify 0 for the upper three bits (bits 31 to 29) of the tag address. For the address and data formats, see figure 9.4. The following three operations are possible for the address array. (1) Address Array Read The tag address, LRU bits, U bit (only for operand cache), and V bit are read from the entry address specified by the address and the entry corresponding to the way. For the read operation, associative operation is not performed regardless of whether the associative bit (A bit) specified by the address is 1 or 0. (2) Address-Array Write (Non-Associative Operation) When the associative bit (A bit) in the address field is cleared to 0, write the tag address, LRU bits, U bit (only for operand cache), and V bit, specified by the data field, to the entry address specified by the address and the entry corresponding to the way. When writing to a cache line for which the U bit = 1 and the V bit = 1 in the operand cache address array, write the contents of the cache line back to memory, then write the tag address, LRU bits, U bit, and V bit specified by the data field. When 0 is written to the V bit, 0 must also be written to the U bit of that entry. Page 262 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 9 Cache Write-back operation to the memory is performed in the following order of the lower 4-bit value of address: H'0 H'4 H'8 H'C. (3) Address-Array Write (Associative Operation) When writing with the associative bit (A bit) of the address field set to 1, the addresses in the four ways for the entry specified by the address field are compared with the tag address that is specified by the data field. Write the U bit (only for operand cache) and the V bit specified by the data field to the entry of the way that has a hit. However, the tag address and LRU bits remain unchanged. When there is no way that has a hit, nothing is written and there is no operation. This function is used to invalidate a specific entry in the cache. When the U bit of the entry that has had a hit is 1 in the operand cache, writing back should be performed. However, when 0 is written to the V bit, 0 must also be written to the U bit of that entry. Write-back operation to the memory is performed in the following order of the lower 4-bit value of address: H'0 H'4 H'8 H'C. 9.4.2 Data Array To access a data array, the 32-bit address field (for read/write accesses) and 32-bit data field (for write accesses) must be specified. The address field specifies information for selecting the entry to be accessed; the data field specifies the longword data to be written to the data array. Specify the entry address for selecting the entry, the L bit indicating the longword position within the (16-byte) line, and the W bit for selecting the way. In the L bit, B'00 is longword 0, B'01 is longword 1, B'10 is longword 2, and B'11 is longword 3. In the W bit, B'00 is way 0, B'01 is way 1, B'10 is way 2, and B'11 is way 3. Since the access size of the data array is fixed at longword, specify B'00 for bits 1 and 0 of the address. For the address and data formats, see figure 9.4. The following two operations are possible for the data array. Information in the address array is not modified by this operation. (1) Data Array Read The data specified by the L bit in the address is read from the entry address specified by the address and the entry corresponding to the way.

When the A bit is 1, the tag address specified by the write data is compared to the tag address within the cache selected by the entry address, and data is written to the bits V and U specified by the write data when a match is found. If no match is found, there is no operation. When the V bit of an entry in the address array is set to 0, the entry is written back if the entry's U bit is 1. An example when a write data is specified in R0 and an address is specified in R1 is shown below. ; R0=H'0110 0010; tag address(28-11)=B'0 0001 0001 0000 0000 0, U=0, V=0 ; R1=H'F080 0088; operand cache address array access, entry=B'000 1000, A=1 ; MOV.L R0,@R1 (2) Reading the Data of a Specific Entry The data section of a specific cache entry can be read by the memory mapping cache access. The longword indicated in the data field of the data array in figure 9.4 is read into the register. An example when an address is specified in R0 and data is read in R1 is shown below. ; R0=H'F100 004C; instruction cache data array access, entry=B'000 0100, ; Way=0, longword address=3 ; MOV.L @R0,R1 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 265 of 3088 Section 9 Cache 9.4.4 SH7268 Group, SH7269 Group Usage Notes 1. Programs that access memory-mapped cache of the operand cache should be placed in a cachedisabled space. Programs that access memory-mapped cache of the instruction cache should be placed in a cache-disabled space, and in each of the beginning and the end of that, two or more read accesses to on-chip peripheral modules or external address space (cache-disabled address) should be executed. 2. Rewriting the address array contents so that two or more ways are hit simultaneously is prohibited. Operation is not guaranteed if the address array contents are changed so that two or more ways are hit simultaneously. 3. Registers and memory-mapped cache can be accessed only by the CPU and not by the direct memory access controller.

External address spaces CS0 to CS5 are cache-enabled when internal address A29 = 0 or cachedisabled when A29 = 1. The kind of memory to be connected and the data bus width are specified in each partial space. The address map for the external address space is listed below.

For the on-chip peripheral module space, access the addresses shown in section 51, List of Registers. Do not access addresses which are not described in these sections. Otherwise, the correct operation cannot be guaranteed. Data Bus Width, Endian Specification, and Related Pin Setting for Each Area Depending on Boot Mode The initial state of data bus width, endian specification, and settings of the pins related to this module depends on boot mode. For boot mode, refer to section 4, Boot Mode. In boot modes 0 and 1, the state of area 0 is fixed to the state with bus width of 16 or 32 bits and big endian, because this LSI is started up by the program stored in the ROM connected to area 0. The initial states of areas 1 to 5 are the same as that of area 0, but can be changed by the program. Immediately after a power-on reset in these modes, some of the address and data-bus signals and the CS0 and RD signals are automatically selected by default as the functions of the corresponding pins, since these signals are required to read ROM data from area 0. With the exception of these pins, the general purpose pin function is selected by default, and other required pin functions must be specified by the program. Read access to area 0 is only permitted before the pin settings are completed. In boot modes 2 to 5, the state of areas 0 to 5 can be changed from the initial state by the program, because the LSI is started by the program stored in the NAND flash memory, the serial flash memory, the NAND flash memory with the SD controller, or the NAND flash memory with the MMC controller. Since pin functions related to this module are not set automatically, they need to be set by the program. Do not access external address spaces before the pin settings are completed. Table 10.3 shows the initial state by areas 0 to 5 in boot modes 0, 1, and 2 to 5. The sample access waveforms shown in this section include the pins such as BS, RD/WR, and WEn. They are the waveforms when pin functions are assigned to the general I/O ports. For example, when 16-bit bus width is used in boot mode 1, setting for pin A1 is needed. When 8-bit bus width is used, setting for pins A1 and A0 is also needed. For details on pin function settings, see section 48, General Purpose I/O Ports.

In boot mode 0 or 1, if a boot ROM that uses higher-order address lines than A21 is connected, the circuit board must include pull-down resistors for those address lines. 2. The data-bus width may be limited by the type of memory in use. For details, section 10.4.2, CSn Space Bus Control Register (CSnBCR) (n = 0 to 5). 3. Since the CS4 and A22 pin functions are assigned to the same pin, area 4 and modules requiring A22 and higher-order address lines cannot be used at the same time.

When RTCOR matches RTCNT, the CMF bit in RTCSR is set to 1 and RTCNT is cleared to 0. When the RFSH bit in SDCR is 1, a memory refresh request is issued by this matching signal. This request is maintained until the refresh operation is performed. If the request is not processed when the next matching occurs, the previous request is ignored. When the CMIE bit in RTCSR is set to 1, an interrupt request is issued by this matching signal. The request continues to be output until the CMF bit in RTCSR is cleared. Clearing the CMF bit only affects the interrupt request and does not clear the refresh request. Therefore, a combination of refresh request and interval timer interrupt can be specified so that the number of refresh requests are counted by using timer interrupts while refresh is performed periodically. When RTCOR is written, the upper 16 bits of the write data must be H'A55A to cancel write protection.

In the initial state after a power-on reset, all areas will be in big endian mode. Endian mode can be changed by setting the CSnBCR register as long as the target space is not being accessed. Data bus width can be selected from 8 bits, 16 bits, and 32 bits for the normal memory and SRAM with byte selection. Data bus width can be selected from 16 bits and 32 bits for SDRAM. Two data bus widths (8 bits and 16 bits) are available for the PCMCIA interface. For MPX-I/O, the data bus width is fixed to either 8 or 16 bits, or made selectable as 8 bits or 16 bits by one of the address lines. Endian specification and data bus width varies depending on boot mode. For details, refer to section 10.3.2, Data Bus Width, Endian Specification, and Related Pin Setting for Each Area Depending on Boot Mode. Data alignment is performed in accordance with the data bus width selected for the device. This also means that four read operations are required to read longword data from a byte-width device. In this LSI, data alignment and conversion of data length is performed automatically between the respective interfaces. Tables 10.5 to 10.10 show the relationship between device data width and access unit. Note that the correspondence between addresses and strobe signals for the 32-bit bus width and 16-bit bus width depends on the endian setting. For example, with big endian and a 16-bit bus width, WE1 corresponds to the 0th address, which is represented by WE0 when little endian has been selected. Since instructions are fetched with both 32- and 16-bit accesses, their alignment in the little-endian area is difficult. Execute instructions from big-endian area.

When writing, only the WEn signal for the byte to be written is asserted. It is necessary to output the data that has been read using RD when a buffer is established in the data bus. The RD/WR signal is in a read state (high output) when no access has been carried out. Therefore, care must be taken when controlling the external data buffer with this signal, to avoid output collision. Figures 10.3 and 10.4 show the basic timings in continuous access to normal space. If the WM bit in CSnWCR is cleared to 0, a Tnop cycle is inserted after the CSn space access to evaluate the external wait (figure 10.3). If the WM bit in CSnWCR is set to 1, external waits are ignored and no Tnop cycle is inserted (figure 10.4).

It is possible for areas 1, 4, and 5 to insert wait cycles independently in read access and in write access. Areas 0, 2, and 3 have common access wait for read cycle and write cycle.

The number of cycles from RD, WEn negation to CSn negation can be specified by setting bits HW1 and HW0. Therefore, a flexible interface to an external device can be obtained. Figure 10.10 shows an example. A Th cycle and a Tf cycle are added before and after an ordinary cycle, respectively. In these cycles, RD and WEn are not asserted, while other signals are asserted. The data output is prolonged to the Tf cycle, and this prolongation is useful for devices with slow writing operations.

In the MPX space, CS5, AH, RD, and WEn signals control the accessing. The basic access for the MPX space consists of 2 cycles of address output followed by an access to a normal space. The bus width for the address output cycle or the data input/output cycle is fixed to 8 bits or 16 bits. Alternatively, it can be 8 bits or 16 bits depending on the address to be accessed. Output of the addresses D15 to D0 or D7 to D0 is performed from cycle Ta2 to cycle Ta3. Because cycle Ta1 has a high-impedance state, collisions of addresses and data can be avoided without inserting idle cycles, even in continuous access cycles. Address output is increased to 3 cycles by setting the MPXW bit in CS5WCR to 1. The RD/WR signal is output at the same time as the CS5 signal; it is high in the read cycle and low in the write cycle. The data cycle is the same as that in a normal space access. The delay cycles specified by SW[1:0] are inserted between the Ta3 and T1 cycles. The delay cycles specified by HW[1:0] are added after the T2 cycle. Timing charts are shown in figures 10.11 to 10.13.

The control signals for direct connection of SDRAM are RAS, CAS, RD/WR, DQMUU, DQMUL, DQMLU, DQMLL, CKE, CS2, and CS3. All the signals other than CS2 and CS3 are common to all areas, and signals other than CKE are valid only when CS2 or CS3 is asserted. SDRAM can be connected to up to 2 spaces. The data bus width of the area that is connected to SDRAM is 16 bits or 32 bits. Burst read/single write (burst length 1) and burst read/burst write (burst length 1) are supported as the SDRAM operating mode. Commands for SDRAM can be specified by RAS, CAS, RD/WR, and specific address signals. These commands supports: * NOP * Auto-refresh (REF) * Self-refresh (SELF) * All banks pre-charge (PALL) * Specified bank pre-charge (PRE) * Bank active (ACTV) * Read (READ) * Read with pre-charge (READA) * Write (WRIT) * Write with pre-charge (WRITA) * Write mode register (MRS, EMRS) The byte to be accessed is specified by DQMUU, DQMUL, DQMLU, and DQMLL. Reading or writing is performed for a byte whose corresponding DQMxx is low. For details on the relationship between DQMxx and the byte to be accessed, see section 10.5.1, Endian/Access Size and Data Alignment.

Tables 10.11 to 10.16 show the relationship between the settings of bits BSZ[1:0], A2ROW[1:0], A2COL[1:0], A3ROW[1:0], and A3COL[1:0] and the bits output at the address pins. Do not specify those bits in the manner other than this table, otherwise the operation of this LSI is not guaranteed. A25 to A18 are not multiplexed and the original values of address are always output at these pins. When the data bus width is 16 bits (BSZ1 and BSZ0 = B'10), A0 of SDRAM specifies a word address. Therefore, connect this A0 pin of SDRAM to the A1 pin of the LSI; the A1 pin of SDRAM to the A2 pin of the LSI, and so on. When the data bus width is 32 bits (BSZ1 and BSZ0 = B'11), A0 of SDRAM specifies a longword address. Therefore, connect this A0 pin of SDRAM to the A2 pin of the LSI; the A1 pin of SDRAM to the A3 pin of the LSI, and so on.

For example, read access of burst length 1 is performed consecutively 8 times to read 16-byte continuous data from the SDRAM that is connected to a 16-bit data bus. This access is called the burst read with the burst number 8. Table 10.17 shows the relationship between the access size and the number of bursts. Table 10.17 Relationship between Access Size and Number of Bursts Bus Width Access Size Number of Bursts 16 bits 8 bits 1 16 bits 1 32 bits 2 16 bytes 8 32 bytes 16 128 bytes 64 8 bits 1 16 bits 1 32 bits 1 16 bytes 4 32 bytes 8 128 bytes 32 32 bits Page 358 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 10 Bus State Controller Figures 10.16 and 10.17 show timing charts in burst read. In burst read, an ACTV command is output in the Tr cycle, the READ command is issued in the Tc1, Tc2, and Tc3 cycles, the READA command is issued in the Tc4 cycle, and the read data is received at the rising edge of the external clock (CKIO) in the Td1 to Td4 cycles. The Tap cycle is used to wait for the completion of an auto-precharge induced by the READA command in the SDRAM. In the Tap cycle, a new command will not be issued to the same bank. However, access to another CS space or another bank in the same SDRAM space is enabled. The number of Tap cycles is specified by the WTRP1 and WTRP0 bits in CS3WCR. In this LSI, wait cycles can be inserted by specifying each bit in CS3WCR to connect the SDRAM in variable frequencies. Figure 10.17 shows an example in which wait cycles are inserted. The number of cycles from the Tr cycle where the ACTV command is output to the Tc1 cycle where the READ command is output can be specified using the WTRCD1 and WTRCD0 bits in CS3WCR. If the WTRCD1 and WTRCD0 bits specify one cycles or more, a Trw cycle where the NOP command is issued is inserted between the Tr cycle and Tc1 cycle. The number of cycles from the Tc1 cycle where the READ command is output to the Td1 cycle where the read data is latched can be specified for the CS2 and CS3 spaces independently, using the A2CL1 and A2CL0 bits in CS2WCR or the A3CL1 and A3CL0 bits in CS3WCR. The number of cycles from Tc1 to Td1 corresponds to the SDRAM CAS latency. The CAS latency for the SDRAM is normally defined as up to three cycles. However, the CAS latency in this LSI can be specified as 1 to 4 cycles. This CAS latency can be achieved by connecting a latch circuit between this LSI and the SDRAM. A Tde cycle is an idle cycle required to transfer the read data into this LSI and occurs once for every burst read or every single read.

For example, write access of burst length 1 is performed continuously 8 times to write 16-byte continuous data to the SDRAM that is connected to a 16-bit data bus. This access is called burst write with the burst number 8. The relationship between the access size and the number of bursts is shown in table 10.17. Figure 10.19 shows a timing chart for burst writes. In burst write, an ACTV command is output in the Tr cycle, the WRIT command is issued in the Tc1, Tc2, and Tc3 cycles, and the WRITA command is issued to execute an auto-precharge in the Tc4 cycle. In the write cycle, the write data is output simultaneously with the write command. After the write command with the auto-precharge is output, the Trw1 cycle that waits for the auto-precharge initiation is followed by the Tap cycle that waits for completion of the auto-precharge induced by the WRITA command in the SDRAM. Between the Trwl and the Tap cycle, a new command will not be issued to the same bank. However, access to another CS space or another bank in the same SDRAM space is enabled. The number of Trw1 cycles is specified by the TRWL1 and TRWL0 bits in CS3WCR. The number of Tap cycles is specified by the WTRP1 and WTRP0 bits in CS3WCR.

When the BACTV bit in SDCR is 1, access is performed using commands without auto-precharge (READ or WRIT). This function is called bank-active function. This function is valid only for area 3. When area 3 is set to bank-active mode, area 2 should be set to normal space or SRAM with byte selection. When areas 2 and 3 are both set to SDRAM, auto precharge mode must be set. When the bank-active function is used, precharging is not performed when the access ends. When accessing the same row address in the same bank, it is possible to issue the READ or WRIT command immediately, without issuing an ACTV command. As SDRAM is internally divided into several banks, it is possible to activate one row address in each bank. If the next access is to a different row address, a PRE command is first issued to precharge the relevant bank, then when precharging is completed, the access is performed by issuing an ACTV command followed by a READ or WRIT command. If this is followed by an access to a different row address, the access time will be longer because of the precharging performed after the access request is issued. The number of cycles between issuance of the PRE command and the ACTV command is determined by the WTRP1 and WTPR0 bits in CS3WCR. In a write, when an auto-precharge is performed, a command cannot be issued to the same bank for a period of Trwl + Tap cycles after issuance of the WRITA command. When bank active mode is used, READ or WRIT commands can be issued successively if the row address is the same. The number of cycles can thus be reduced by Trwl + Tap cycles for each write. There is a limit on tRAS, the time for placing each bank in the active state. If there is no guarantee that there will not be a cache hit and another row address will be accessed within the period in which this value is maintained by program execution, it is necessary to set auto-refresh and set the refresh cycle to no more than the maximum value of tRAS. A burst read cycle without auto-precharge is shown in figure 10.21, a burst read cycle for the same row address in figure 10.22, and a burst read cycle for different row addresses in figure 10.23. Similarly, a single write cycle without auto-precharge is shown in figure 10.24, a single write cycle for the same row address in figure 10.25, and a single write cycle for different row addresses in figure 10.26. In figure 10.22, a Tnop cycle in which no operation is performed is inserted before the Tc cycle that issues the READ command. The Tnop cycle is inserted to acquire two cycles of CAS latency for the DQMxx signal that specifies the read byte in the data read from the SDRAM. If the CAS latency is specified as two cycles or more, the Tnop cycle is not inserted because the two cycles of latency can be acquired even if the DQMxx signal is asserted after the Tc cycle. Page 366 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 10 Bus State Controller When bank active mode is set, if only access cycles to the respective banks in the area 3 space are considered, as long as access cycles to the same row address continue, the operation starts with the cycle in figure 10.21 or 10.24, followed by repetition of the cycle in figure 10.22 or 10.25. An access to a different area during this time has no effect. If there is an access to a different row address in the bank active state, the bus cycle in figure 10.23 or 10.26 is executed instead of that in figure 10.22 or 10.25. In bank active mode, too, all banks become inactive after a refresh cycle or after the bus is released as the result of bus arbitration.

Figure 10.26 Single Write Timing (Bank Active, Different Row Addresses in the Same Bank) (8) Refreshing This module has a function for controlling SDRAM refreshing. Auto-refreshing can be performed by clearing the RMODE bit to 0 and setting the RFSH bit to 1 in SDCR. A continuous refreshing can be performed by setting the RRC2 to RRC0 bits in RTCSR. If SDRAM is not accessed for a long period, self-refresh mode, in which the power consumption for data retention is low, can be activated by setting both the RMODE bit and the RFSH bit to 1. Page 372 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (a) Section 10 Bus State Controller Auto-refreshing Refreshing is performed at intervals determined by the input clock selected by bits CKS2 to CKS0 in RTCSR, and the value set by in RTCOR. The value of bits CKS2 to CKS0 in RTCOR should be set so as to satisfy the refresh interval stipulation for the SDRAM used. First make the settings for RTCOR, RTCNT, and the RMODE and RFSH bits in SDCR, and then make the CKS2 to CKS0 and RRC2 to RRC0 settings. When the clock is selected by bits CKS2 to CKS0, RTCNT starts counting up from the value at that time. The RTCNT value is constantly compared with the RTCOR value, and if the two values are the same, a refresh request is generated and an autorefresh is performed for the number of times specified by the RRC2 to RRC0. At the same time, RTCNT is cleared to zero and the count-up is restarted. Figure 10.27 shows the auto-refresh cycle timing. After starting the auto refreshing, PALL command is issued in the Tp cycle to make all the banks to pre-charged state from active state when some bank is being pre-charged. Then REF command is issued in the Trr cycle after inserting idle cycles of which number is specified by the WTRP1 and WTRP0 bits in CS3WCR. A new command is not issued for the duration of the number of cycles specified by the WTRC1 and WTRC0 bits in CS3WCR after the Trr cycle. The WTRC1 and WTRC0 bits must be set so as to satisfy the SDRAM refreshing cycle time stipulation (tRC). An idle cycle is inserted between the Tp cycle and Trr cycle when the setting value of the WTRP1 and WTRP0 bits in CS3WCR is longer than or equal to 1 cycle.

Self-refreshing is activated by setting both the RMODE bit and the RFSH bit in SDCR to 1. After starting the self-refreshing, PALL command is issued in Tp cycle after the completion of the pre-charging bank. A SELF command is then issued after inserting idle cycles of which number is specified by the WTRP1 and WTRP0 bits in CS3WSR. SDRAM cannot be accessed while in the self-refresh state. Self-refresh mode is cleared by clearing the RMODE bit to 0. After self-refresh mode has been cleared, command issuance is disabled for the number of cycles specified by the WTRC1 and WTRC0 bits in CS3WCR. Self-refresh timing is shown in figure 10.28. Settings must be made so that self-refresh clearing and data retention are performed correctly, and auto-refreshing is performed at the correct intervals. When self-refreshing is activated from the state in which auto-refreshing is set, autorefreshing is restarted if the RFSH bit is set to 1 and the RMODE bit is cleared to 0 when selfrefresh mode is cleared. If the transition from clearing of self-refresh mode to the start of autorefreshing takes time, this time should be taken into consideration when setting the initial value of RTCNT. Making the RTCNT value 1 less than the RTCOR value will enable refreshing to be started immediately. After self-refreshing has been set, the self-refresh state continues even if the chip standby state is entered using the LSI standby function, and is maintained even after recovery from standby mode due to an interrupt. Note that the necessary signals such as CKE must be driven even in standby state by setting the HIZCNT bit in CMNCR to 1. When the multiplication rate for the PLL circuit is changed, the CKIO output will become unstable or will be fixed low. For details on the CKIO output, see section 5, Clock Pulse Generator. The contents of SDRAM can be retained by placing the SDRAM in the self-refresh state before changing the multiplication rate. The self-refresh state is not cleared by a manual reset. In case of a power-on reset, the bus state controller's registers are initialized, and therefore the self-refresh state is cleared.

If a refresh request occurs while the bus is released by the bus arbitration function, the refresh will not be executed until the bus mastership is acquired. If the external bus does not return the bus for a period longer than the specified refresh interval, refresh cannot be executed and the SDRAM contents may be lost. If a new refresh request occurs while waiting for the previous refresh request, the previous refresh request is deleted. To refresh correctly, a bus cycle longer than the refresh interval or the bus mastership occupation must be prevented from occurring. If a bus mastership is requested during self-refresh, the bus will not be released until the refresh is completed.

This power-down mode can effectively lower the power consumption in the non-access cycle. However, please note that if an access occurs in power-down mode, a cycle of overhead occurs because a cycle is needed to assert the CKE in order to cancel the power-down mode.

The pose interval should be obtained by a power-on reset generating circuit or software. To perform SDRAM initialization correctly, the registers of this module must first be set, followed by a write to the SDRAM mode register. In SDRAM mode register setting, the address signal value at that time is latched by a combination of the CSn, RAS, CAS, and RD/WR signals. If the value to be set is X, the bus state controller provides for value X to be written to the SDRAM mode register by performing a word write to address H'FFFC4000 + X for area 2 SDRAM, and to address H'FFFC5000 + X for area 3 SDRAM. In this operation the data is ignored, but the mode write is performed as a byte-size access. To set burst read/single write or burst read/burst write (CAS latency 2 to 3, wrap type = sequential, and burst length 1) supported by the LSI, arbitrary data is written in a byte-size access to the addresses shown in table 10.18. In this time 0 is output at the external address pins of A12 or later.

A PALL command (all bank pre-charge command) is firstly issued. A REF command (auto refresh command) is then issued 8 times. An MRS command (mode register write command) is finally issued. Idle cycles, of which number is specified by the WTRP1 and WTRP0 bits in CS3WCR, are inserted between the PALL and the first REF. Idle cycles, of which number is specified by the WTRC1 and WTRC0 bits in CS3WCR, are inserted between REF and REF, and between the 8th REF and MRS. One or more idle cycles are inserted between the MRS and a command to be issued next. It is necessary to keep idle time of certain cycles for SDRAM before issuing PALL command after power-on. Refer to the manual of the SDRAM for the idle time to be needed. When the pulse width of the reset signal is longer than the idle time, mode register setting can be started immediately after the reset, but care should be taken when the pulse width of the reset signal is shorter than the idle time.

The differences between the low-power SDRAM and normal SDRAM are that partial refresh takes place that puts only a part of the SDRAM in the self-refresh state during the self-refresh function, and that power consumption is low during refresh under user conditions such as the operating temperature. The partial refresh is effective in systems in which the data in a work area other than the specific area can be lost without severe repercussions. For details, please refer to the Data Sheet for the low-power SDRAM to be used. The low-power SDRAM supports the extension mode register in addition to the mode registers as the normal SDRAM. This LSI supports issuing of the extension mode register write command (EMRS). The EMRS command is issued according to the conditions specified in table below. For example, if data H'0YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued to the CS3 space in the following sequence: PALL -> REF x 8 -> MRS -> EMRS. In this case, the MRS and EMRS issue addresses are H'0000XX0 and H'YYYYYYY, respectively. If data H'1YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued to the CS3 space in the following sequence: PALL -> MRS -> EMRS.

In the partial self-refresh function, self-refresh is performed on a specific area. In the deep power-down mode, self-refresh will not be performed on any memory area. This mode is effective in systems where all of the system memory areas are used as work areas. If the RMODE bit in the SDCR is set to 1 while the DEEP and RFSH bits in the SDCR are set to 1, the low-power SDRAM enters the deep power-down mode. If the RMODE bit is cleared to 0, the CKE signal is pulled high to cancel the deep power-down mode. Before executing an access after returning from the deep power-down mode, the power-up sequence must be re-executed.

In a burst ROM (clocked asynchronous) interface, basically the same access as the normal space is performed, but the 2nd and subsequent access cycles are performed only by changing the address, without negating the RD signal at the end of the 1st cycle. In the 2nd and subsequent access cycles, addresses are changed at the falling edge of the CKIO. For the 1st access cycle, the number of wait cycles specified by the W3 to W0 bits in CSnWCR is inserted. For the 2nd and subsequent access cycles, the number of wait cycles specified by the BW1 and BW0 bits in CSnWCR is inserted. In the access to the burst ROM (clocked asynchronous), the BS signal is asserted only to the first access cycle. An external wait input is valid only to the first access cycle. In the single access or write access that does not perform the burst operation in the burst ROM (clocked asynchronous) interface, access timing is same as a normal space. Table 10.20 lists a relationship between bus width, access size, and the number of bursts. Figure 10.33 shows a timing chart.

This interface has 16-bit data pins and accesses SRAMs having upper and lower byte selection pins, such as UB and LB. When the BAS bit in CSnWCR is cleared to 0 (initial value), the write access timing of the SRAM interface with byte selection is the same as that for the normal space interface. While in read access of a byte-selection SRAM interface, the byte-selection signal is output from the WEn pin, which is different from that for the normal space interface. The basic access timing is shown in figure 10.34. In write access, data is written to the memory according to the timing of the byteselection pin (WEn). For details, please refer to the Data Sheet for the corresponding memory. If the BAS bit in CSnWCR is set to 1, the WEn pin and RD/WR pin timings change. Figure 10.35 shows the basic access timing. In write access, data is written to the memory according to the timing of the write enable pin (RD/WR). The data hold timing from RD/WR negation to data write must be acquired by setting the HW1 and HW0 bits in CSnWCR. Figure 10.36 shows the access timing when a software wait is specified.

In addition, the bits SA[1:0] in CS5WCR assign the upper or lower 32 Mbytes of area 5 to IC memory card or I/O card interface. For example, if the bits SA1 and SA0 in CS5WCR are set to 1 and cleared to 0, respectively, the upper 32 Mbytes of area 5 are used for IC memory card interface and the lower 32 Mbytes are used for I/O card interface. When the PCMCIA interface is used, the bus size must be specified as 8 bits or 16 bits using the bits BSZ[1:0] in CS5BCR. Figure 10.39 shows an example of connection between this LSI and a PCMCIA card. To enable hot swapping (insertion and removal of the PCMCIA card with the system power turned on), tristate buffers must be connected between the bus interface of this LSI and the PCMCIA card. In the JEIDA and PCMCIA standards, operation in big endian mode is not clearly defined. Consequently, the provided PCMCIA interface in big endian mode is available only for this LSI.

When area 5 is specified as the PCMCIA interface, the bus is accessed with the IC memory card interface according to the SA[1:0] bit settings in CS5WCR. If the external bus frequency (CKIO) increases, the setup times and hold times for the address pins (A25 to A0), card enable signals (CE1A, CE2A), and write data (D15 to D0) to the RD and WE signals become insufficient. To prevent this error, this LSI enables the setup times and hold times for area 5 to be specified independently, using CS5WCR. In the PCMCIA interface, as in the normal space interface, a software wait or hardware wait using the WAIT pin can be inserted. Figure 10.41 shows the PCMCIA memory bus wait timing.

As shown in the example in figure 10.42, when the total memory space necessary for the common memory and attribute memory is 32 Mbytes or less, pin A24 can be used as the REG signal to allocate a 16-Mbyte common memory space and a 16-Mbyte attribute memory space.

When accessing an I/O card through the PCMCIA interface, be sure to access the space as cachedisabled. Switching between I/O card and IC memory card interfaces in the respective address spaces is accomplished by the SA[1:0] bit settings in CS5WCR. The IOIS16 pin can be used for dynamic adjustment of the width of the I/O bus in access to an I/O card via the PCMCIA interface when little endian mode has been selected. When the bus width of area 5 is set to 16 bits and the IOIS16 signal is driven high during a cycle of word-unit access to the I/O card bus, the bus width will be recognized as 8 bits and only 8 bits of data will be accessed during the current cycle of the I/O card bus. Operation will automatically continue with access to the remaining 8 bits of data. The IOIS16 signal is sampled on falling edges of the CKIO in Tpci0 as well as all Tpci0w cycles for which the TED3 to TED0 bits are set to 1.5 cycles or more, and the CE2A signal is updated after 1.5 cycles of the CKIO signal from the sampling point of Tpci0. Ensure that the IOIS16 signal is defined at all sampling points and does not change along the way. Set the TED3 to TED0 bits to satisfy the requirement of the PC card in use with regard to setup timing from ICIORD or ICIOWR to CE1. The basic waveforms for dynamic bus-size adjustment are shown in figure 10.44. Since the IOIS16 signal is not supported in big endian mode, the IOIS16 signal should be fixed to the low level when big endian mode has been selected.

The burst ROM interface accesses the burst ROM in the same way as a normal space. This interface is valid only for area 0. In the first access cycle, wait cycles are inserted. In this case, the number of wait cycles to be inserted is specified by the W3 to W0 bits in CS0WCR. In the second and subsequent cycles, the number of wait cycles to be inserted is specified by the BW1 and BW0 bits in CS0WCR. While the burst ROM (clocked synchronous) is accessed, the BS signal is asserted only for the first access cycle and an external wait input is also valid for the first access cycle. When the bus width is 16 bits, the burst length must be specified as 8. When the bus width is 32 bits, the burst length must be specified as 4. The burst ROM interface does not support the 8-bit bus width for the burst ROM. The burst ROM interface performs burst operations for all read access. For example, in a longword access over a 16-bit bus, valid 16-bit data is read two times and invalid 16-bit data is read six times. These invalid data read cycles increase the memory access time and degrade the program execution speed and DMA transfer speed. To prevent this problem, it is recommended using a 16-byte read by cache fill in the cache-enabled spaces or 16-byte read by the DMA. The burst ROM interface performs write access in the same way as normal space access.

As a result of these collisions, the reliability of the device is low and malfunctions may occur. A function that avoids data collisions by inserting idle (wait) cycles between continuous access cycles has been newly added. The number of wait cycles between access cycles can be set by the WM bit in CSnWCR, bits IWW2 to IWW0, IWRWD2 to IWRWD0, IWRWS2 to IWRWS0, IWRRD2 to IWRRD0, and IWRRS2 to IWRRS 0 in CSnBCR, and bits DMAIW2 to DMAIW0 and DMAIWA in CMNCR. The conditions for setting the idle cycles between access cycles are shown below. 1. Continuous access cycles are write-read or write-write 2. Continuous access cycles are read-write for different spaces 3. Continuous access cycles are read-write for the same space 4. Continuous access cycles are read-read for different spaces 5. Continuous access cycles are read-read for the same space 6. Data output from an external device caused by DMA single address transfer is followed by data output from another device that includes this LSI (DMAIWA = 0) 7. Data output from an external device caused by DMA single address transfer is followed by any type of access (DMAIWA = 1) For the specification of the number of idle cycles between access cycles described above, refer to the description of each register. Besides the idle cycles between access cycles specified by the registers, idle cycles must be inserted to interface with the internal bus or to obtain the minimum pulse width for a multiplexed pin (WEn). The following gives detailed information about the idle cycles and describes how to estimate the number of idle cycles. The number of idle cycles on the external bus from CSn negation to CSn or CSm assertion is described below. Here, CSn and CSm also include CE2A for PCMCIA. There are eight conditions that determine the number of idle cycles on the external bus as shown in table 10.21. The effects of these conditions are shown in figure 10.46. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 399 of 3088 SH7268 Group, SH7269 Group Section 10 Bus State Controller Table 10.21 Conditions for Determining Number of Idle Cycles No. Condition Description [1] DMAIW[2:0] in CMNCR These bits specify the number of 0 to 12 idle cycles for DMA single address transfer. This condition is effective only for single address transfer and generates idle cycles after the access is completed. When 0 is specified for the number of idle cycles, the DACK signal may be asserted continuously. This causes a discrepancy between the number of cycles detected by the device with DACK and the direct memory access controller transfer count, resulting in a malfunction. [2] IW***[2:0] in CSnBCR These bits specify the number of 0 to 12 idle cycles for access other than single address transfer. The number of idle cycles can be specified independently for each combination of the previous and next cycles. For example, in the case where reading CS1 space followed by reading other CS space, the bits IWRRD[2:0] in CS1BCR should be set to B'100 to specify six or more idle cycles. This condition is effective only for access cycles other than single address transfer and generates idle cycles after the access is completed. Do not set 0 for the number of idle cycles between memory types which are not allowed to be accessed successively. [3] SDRAM-related These bits specify precharge 0 to 3 bits in completion and startup wait cycles CSnWCR and idle cycles between commands for SDRAM access. This condition is effective only for SDRAM access and generates idle cycles after the access is completed Page 400 of 3088 Range Note Specify these bits in accordance with the specification of the target SDRAM. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 10 Bus State Controller No. Condition Description [4] WM in CSnWCR This bit enables or disables external 0 or 1 WAIT pin input for the memory types other than SDRAM. When this bit is cleared to 0 (external WAIT enabled), one idle cycle is inserted to check the external WAIT pin input after the access is completed. When this bit is set to 1 (disabled), no idle cycle is generated. [5] Read data transfer cycle One idle cycle is inserted after a 0 or 1 read access is completed. This idle cycle is not generated for the first or middle cycles in divided access cycles. This is neither generated when the HW[1:0] bits in CSnWCR are not B'00. One idle cycle is always generated after a read cycle with SDRAM or PCMCIA interface. [6] Internal bus External bus access requests from 0 or idle cycles, etc. the CPU or the direct memory larger access controller and their results are passed through the internal bus. The external bus enters idle state during internal bus idle cycles or while a bus other than the external bus is being accessed. This condition is not effective for divided access cycles, which are generated by the bus state controller when the access size is larger than the external data bus width. The number of internal bus idle cycles may not become 0 depending on the I:B:CKIO clock ratio. Tables 10.22 and 10.23 show the relationship between the clock ratio and the minimum number of internal bus idle cycles. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Range Note Page 401 of 3088 SH7268 Group, SH7269 Group Section 10 Bus State Controller No. Condition Description Range Note [7] Write data wait During write access, a write cycle is 0 or 1 cycles executed on the external bus only after the write data becomes ready. This write data wait period generates idle cycles before the write cycle. Note that when the previous cycle is a write cycle and the internal bus idle cycles are shorter than the previous write cycle, write data can be prepared in parallel with the previous write cycle and therefore, no idle cycle is generated (write buffer effect). For write write or write read access cycles, successive access cycles without idle cycles are frequently available due to the write buffer effect described in the left column. If successive access cycles without idle cycles are not allowed, specify the minimum number of idle cycles between access cycles through CSnBCR. [8] Idle cycles between different memory types The number of idle cycles depends on the target memory types. See table 10.24. To ensure the minimum pulse width 0 to 2 on the signal-multiplexed pins, idle cycles may be inserted before access after memory types are switched. For some memory types, idle cycles are inserted even when memory types are not switched. In the above conditions, a total of four conditions, that is, condition [1] or [2] (either one is effective), condition [3] or [4] (either one is effective), a set of conditions [5] to [7] (these are generated successively, and therefore the sum of them should be taken as one set of idle cycles), and condition [8] are generated at the same time. The maximum number of idle cycles among these four conditions become the number of idle cycles on the external bus. To ensure the minimum idle cycles, be sure to make register settings for condition [1] or [2].

In the actual operation, the idle cycles may become shorter than the estimated value due to the write buffer effect or may become longer due to internal bus idle cycles caused by stalling in the pipeline due to CPU instruction execution or CPU register conflicts. Please consider these errors when estimating the idle cycles. Sample Estimation of Idle Cycles between Access Cycles This example estimates the idle cycles for data transfer from the CS1 space to CS2 space by CPU access. Transfer is repeated in the following order: CS1 read CS1 read CS2 write CS2 write CS1 read ... * Conditions The bits for setting the idle cycles between access cycles in CS1BCR and CS2BCR are all set to 0. In CS1WCR and CS2WCR, the WM bit is set to 1 (external WAIT pin disabled) and the HW[1:0] bits are set to 00 (CS negation is not extended). I:B:CKIO is set to 4:1:1, and no other processing is done during transfer. For both the CS1 and CS2 spaces, normal SRAM devices are connected, the bus width is 32 bits, and access size is also 32 bits. The idle cycles generated under each condition are estimated for each pair of access cycles. In the following table, R indicates a read cycle and W indicates a write cycle. RR RW WW WR [1] or [2] 0 0 0 0 CSnBCR is set to 0. [3] or [4] 0 0 0 0 The WM bit is set to 1. [5] 1 1 0 0 Generated after a read cycle. [6] 0 2 2 0 See the I:B:CKIO = 4:1:1 columns in table 10.22.

Condition Note Figure 10.47 Comparison between Estimated Idle Cycles and Actual Value R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 405 of 3088 Section 10 Bus State Controller SH7268 Group, SH7269 Group 10.5.12 Bus Arbitration The bus arbitration of this LSI has the bus mastership in the normal state and releases the bus mastership after receiving a bus request from another device. Bus mastership is transferred at the boundary of bus cycles. Namely, bus mastership is released immediately after receiving a bus request when a bus cycle is not being performed. The release of bus mastership is delayed until the bus cycle is complete when a bus cycle is in progress. Even when from outside the LSI it looks like a bus cycle is not being performed, a bus cycle may be performing internally, started by inserting wait cycles between access cycles. Therefore, it cannot be immediately determined whether or not bus mastership has been released by looking at the CSn signal or other bus control signals. The states that do not allow bus mastership release are shown below. 1. 16-byte transfer because of a cache miss 2. During write-back operation for the cache 3. Between the read and write cycles of a TAS instruction 4. Multiple bus cycles generated when the data bus width is smaller than the access size (for example, between bus cycles when longword access is made to a memory with a data bus width of 8 bits) 5. 16-byte transfer by the direct memory access controller 6. 32-byte transfer by the OpenVGTM-compliant Renesas graphics processor, image renderer, and video display controller 4 7. 128-byte transfer by the video display controller 4 8. Setting the BLOCK bit in CMNCR to 1 9. During access to the external flash memory by the NAND flash memory controller Moreover, by using DPRTY bit in CMNCR, whether the bus mastership request is received or not can be selected during burst transfer by the direct memory access controller. The LSI has the bus mastership until a bus request is received from another device. Upon acknowledging the assertion (low level) of the external bus request signal BREQ, the LSI releases the bus at the completion of the current bus cycle and asserts the BACK signal. After the LSI acknowledges the negation (high level) of the BREQ signal that indicates the external device has released the bus, it negates the BACK signal and resumes the bus usage. With the SDRAM interface, all bank pre-charge commands (PALLs) are issued when active banks exist and the bus is released after completion of a PALL command. Page 406 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 10 Bus State Controller The bus sequence is as follows. The address bus and data bus are placed in a high-impedance state synchronized with the rising edge of CKIO. The bus mastership enable signal is asserted 0.5 cycles after the above timing, synchronized with the falling edge of CKIO. The bus control signals (BS, CSn, RAS, CAS, CKE, DQMxx, WEn, RD, and RD/WR) are placed in the high-impedance state at subsequent rising edges of CKIO. These bus control signals are driven high one or more cycles before they are placed in the high-impedance state. Bus request signals are sampled at the falling edge of CKIO. Note that CKE, RAS, and CAS can be continued to be driven at the previous value even in the bus-released state by setting the HIZCNT bit in CMNCR. The sequence for reclaiming the bus mastership from an external device is described below. 1.5 cycles after the negation of BREQ is detected at the falling edge of CKIO, the bus control signals are driven high. The bus acknowledge signal is negated at the next falling edge of the clock. The fastest timing at which actual bus cycles can be resumed after bus control signal assertion is at the rising edge of the CKIO where address and data signals are driven. Figure 10.48 shows the bus arbitration timing. When it is necessary to refresh SDRAM while releasing the bus mastership, the bus mastership should be returned. If the bus mastership is not returned for a specified refreshing period or longer, the contents of SDRAM cannot be guaranteed because a refreshing cannot be executed. While releasing the bus mastership, the SLEEP instruction (to enter sleep mode, deep standby mode, or software standby mode), as well as a manual reset, cannot be executed until the LSI obtains the bus mastership. The BREQ input signal is ignored in software standby mode or deep standby mode and the BACK output signal is placed in the high impedance state. If the bus mastership request is required in this state, the bus mastership must be released by pulling down the BACK pin to enter software standby mode or deep standby mode. The bus mastership release (BREQ signal for high level negation) after the bus mastership request (BREQ signal for low level assertion) must be performed after the bus usage permission (BACK signal for low level assertion). If the BREQ signal is negated before the BACK signal is asserted, only one cycle of the BACK signal is asserted depending on the timing of the BREQ signal to be negated and this may cause a bus contention between the external device and the LSI.

At power-on reset, all signals are negated and data output buffers are turned off regardless of the bus cycle state after the internal reset is synchronized with the internal clock. All control registers are initialized. In software standby, sleep, and manual reset, control registers of the bus state controller are not initialized. At manual reset, only the current bus cycle being executed is completed. Since the RTCNT continues counting up during manual reset signal assertion, a refresh request occurs to initiate the refresh cycle. (2) Access from the Side of the LSI Internal Bus Master There are three types of LSI internal buses: a CPU bus, internal bus, and peripheral bus. The CPU and cache memory are connected to the CPU bus. The bus state controller and internal bus masters other than the CPU are connected to the internal bus. Low-speed peripheral modules are connected to the peripheral bus. Internal memories other than the cache memory are connected bidirectionally to the CPU bus and internal bus. Access from the CPU bus to the internal bus is enabled but access from the internal bus to the CPU bus is disabled. This gives rise to the following problems. On-chip bus masters such as the direct memory access controller other than the CPU can access internal memory other than the cache memory but cannot access the cache memory. If an on-chip bus master other than the CPU writes data to an external memory other than the cache, the contents of the external memory may differ from that of the cache memory. To prevent this problem, if the external memory whose contents is cached is written by an on-chip bus master other than the CPU, the corresponding cache memory should be purged by software. In a cache-enabled space, if the CPU initiates read access, the cache is searched. If the cache stores data, the CPU latches the data and completes the read access. If the cache does not store data, the CPU performs four contiguous longword read cycles to perform cache fill operations via the internal bus. If a cache miss occurs in byte or word operand access or at a branch to an odd word boundary (4n + 2), the CPU performs four contiguous longword access cycles to perform a cache fill operation on the external interface. For a cache-disabled space, the CPU performs access according to the actual access addresses. For an instruction fetch to an even word boundary (4n), the CPU performs longword access. For an instruction fetch to an odd word boundary (4n + 2), the CPU performs word access. For a read cycle of an on-chip peripheral module, the cycle is initiated through the internal bus and peripheral bus. The read data is sent to the CPU via the peripheral bus, internal bus, and CPU bus. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 409 of 3088 Section 10 Bus State Controller SH7268 Group, SH7269 Group In a write cycle for the cache-enabled space, the write cycle operation differs according to the cache write methods. In write-back mode, the cache is first searched. If data is detected at the address corresponding to the cache, the data is then re-written to the cache. In the actual memory, data will not be re-written until data in the corresponding address is re-written. If data is not detected at the address corresponding to the cache, the cache is modified. In this case, data to be modified is first saved to the internal buffer, 16-byte data including the data corresponding to the address is then read, and data in the corresponding access of the cache is finally modified. Following these operations, a write-back cycle for the saved 16-byte data is executed. In write-through mode, the cache is first searched. If data is detected at the address corresponding to the cache, the data is re-written to the cache simultaneously with the actual write via the internal bus. If data is not detected at the address corresponding to the cache, the cache is not modified but an actual write is performed via the internal bus. Since the bus state controller incorporates a one-stage write buffer, it can execute an access via the internal bus before the previous external bus cycle is completed in a write cycle. If the on-chip module is read or written after the external low-speed memory is written, the on-chip module can be accessed before the completion of the external low-speed memory write cycle. In read cycles, the CPU is placed in the wait state until read operation has been completed. To continue the process after the data write to the device has been completed, perform a dummy read to the same address to check for completion of the write before the next process to be executed. The write buffer of the bus state controller functions in the same way for an access by a bus master other than the CPU such as the direct memory access controller. Accordingly, to perform dual address DMA transfers, the next read cycle is initiated before the previous write cycle is completed. Note, however, that if both the DMA source and destination addresses exist in external memory space, the next read cycle will not be initiated until the previous write cycle is completed. Changing the registers in this module while the write buffer is operating may disrupt correct write access. Therefore, do not change the registers in this module immediately after a write access. If this change becomes necessary, do it after executing a dummy read of the write data. Page 410 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (3) Section 10 Bus State Controller On-Chip Peripheral Module Access To access an on-chip module register, two or more peripheral module clock (P0 or P1) cycles are required. Care must be taken in system design. When the CPU writes data to the internal peripheral registers, the CPU performs the succeeding instructions without waiting for the completion of writing to registers. For example, a case is described here in which the system is transferring to the software standby mode for power savings. To make this transition, the SLEEP instruction must be performed after setting the STBY bit in the STBCR1 register to 1. However a dummy read of the STBCR1 register is required before executing the SLEEP instruction. If a dummy read is omitted, the CPU executes the SLEEP instruction before the STBY bit is set to 1, thus the system enters sleep mode not software standby mode. A dummy read of the STBCR1 register is indispensable to complete writing to the STBY bit. To reflect the change by internal peripheral registers while performing the succeeding instructions, execute a dummy read of registers to which write instruction is given and then perform the succeeding instructions. (4) External Flash Memory Access by NAND Flash Memory Controller In this product, a part of the external data bus is used also as data bus for the NAND flash memory controller. The use of the data bus is controlled by the NAND flash memory controller. Memory access by the NAND flash memory controller is started after the preceding access to the external device by this module is completed. If an access to the external device by this module occurs during the access by the NAND flash memory controller, it must wait until the completion of the access by the NAND flash memory controller. When a memory access request by the NAND flash memory controller and an external bus release request conflict with each other, the request accepted first has higher priority. When the two requests occur at the same time, the access by the NAND flash memory controller has higher priority. Auto-refresh operation and self-refresh operation are executed even during a memory access by the NAND flash memory controller.

The transfer count is 1 when the setting is H'00000001, 16,777,215 when H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. During a DMA transfer, these registers indicate the remaining transfer count. The upper eight bits of DMATCR are always read as 0, and the write value should always be 0. To transfer data in 16 bytes, one 16-byte transfer (128 bits) counts one.

Setting this bit to 1 generates an interrupt request (DEI) to the CPU when TE bit is set to 1. 0: Disables an interrupt request 1: Enables an interrupt request 1 TE 0 R/(W)* Transfer End Flag This bit is set to 1 when DMATCR becomes 0 and DMA transfer ends. The TE bit is not set to 1 in the following cases. * DMA transfer ends due to an NMI interrupt or DMA address error before DMATCR becomes 0. * DMA transfer is ended by clearing the DE bit and DME bit in DMA operation register (DMAOR). To clear the TE bit, write 0 after reading TE = 1.

In auto request mode, DMA transfer starts by setting the DE bit and DME bit in DMAOR to 1. In this case, all of the bits TE, NMIF in DMAOR, and AE must be 0. In an external request or peripheral module request, DMA transfer starts if DMA transfer request is generated by the devices or peripheral modules after setting the bits DE and DME to 1. If the DREQ signal is detected by low/high level in external request mode, or in peripheral module request mode, the NMIF bit and the AE bit must be 0 if the TEMASK bit is 1. If the TEMASK bit is 0, the TE bit must also be 0. If the DREQ signal is detected by a rising/falling edge in external request mode, all of the bits TE, NMIF, and AE must be 0 as in the case of auto request mode. Clearing the DE bit to 0 can terminate the DMA transfer. 0: DMA transfer disabled 1: DMA transfer enabled Note: * Only 0 can be written to clear the flag after 1 is read.

When the SAR reload function is enabled, the RSAR value is written to the source address register (SAR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer can be preset in RSAR during the current DMA transfer. When the SAR reload function is disabled, RSAR is ignored. To transfer data in word (2-byte), longword (4-byte), or 16-byte unit, specify the address with 2byte, 4-byte, or16-byte address boundary respectively.

When the DAR reload function is enabled, the RDAR value is written to the destination address register (DAR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer can be preset in RDAR during the current DMA transfer. When the DAR reload function is disabled, RDAR is ignored. To transfer data in word (2-byte), longword (4-byte), or 16-byte unit, specify the address with 2byte, 4-byte, or16-byte address boundary respectively.

When the SAR/DAR reload function is enabled, the RDMATCR value is written to the transfer count register (DMATCR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer can be preset in RDMATCR during the current DMA transfer. When the SAR/DAR reload function is disabled, RDMATCR is ignored. The upper eight bits of RDMATCR are always read as 0, and the write value should always be 0. As in DMATCR, the transfer count is 1 when the setting is H'00000001, 16,777,215 when H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. To transfer data in 16 bytes, one 16-byte transfer (128 bits) counts one.

The transfer request from DMARS is valid only when the resource select bits (RS3 to RS0) in CHCR0 to CHCR15 have been set to B'1000. Otherwise, even if DMARS has been set, the transfer request source is not accepted. Page 450 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 11.4 Section 11 Direct Memory Access Controller Operation When there is a DMA transfer request, this module starts the transfer according to the predetermined channel priority order; when the transfer end conditions are satisfied, it ends the transfer. Transfers can be requested in three modes: auto request, external request, and on-chip peripheral module request. In bus mode, the burst mode or the cycle steal mode can be selected. 11.4.1 Transfer Flow After the DMA source address registers (SAR), DMA destination address registers (DAR), DMA transfer count registers (DMATCR), DMA channel control registers (CHCR), DMA operation register (DMAOR), three reload registers (RSAR, RDAR, RDMATCR) and DMA extension resource selector (DMARS) are set for the target transfer conditions, this module transfers data according to the following procedure: 1. Checks to see if transfer is enabled (DE = 1, DME = 1, TEMASK = 0 or 1 (TE = 0 when TEMASK = 0), AE = 0, NMIF = 0). 2. When a transfer request comes and transfer is enabled, this module transfers one transfer unit of data (depending on the settings of the TS1 and TS0 bits). For an auto request, the transfer begins automatically when the DE bit and DME bit are set to 1. The DMATCR value will be decremented by 1 for each transfer. The actual transfer flows vary by address mode and bus mode. 3. When half of the specified transfer count is exceeded (when DMATCR reaches half of the initial value), an HEI interrupt is sent to the CPU if the HIE bit in CHCR is set to 1. 4. When transfer has been completed for the specified count (when DMATCR reaches 0) while the TEMASK bit is 0, the transfer ends normally. If the IE bit in CHCR is set to 1 at this time, a DEI interrupt is sent to the CPU. When DMATCR reaches 0 while the TEMASK bit is 1, the TE bit is set to 1 and then the values set in RSAR, RDAR and RDMATCR are reloaded in SAR, DAR and DMATCR, respectively to continue transfer operation until the DMA transfer request is cancelled. 5. When an address error in this module or an NMI interrupt is generated, the transfer is terminated. Transfers are also terminated when the DE bit in CHCR or the DME bit in DMAOR is cleared to 0.

Transfers can be requested in three modes: auto request, external request, and on-chip peripheral module request. The request mode is selected by the RS[3:0] bits in CHCR_0 to CHCR_15 and DMARS0 to DMARS7. (1) Auto-Request Mode When there is no transfer request signal from an external source, as in a memory-to-memory transfer or a transfer between memory and an on-chip peripheral module unable to request a transfer, the auto-request mode allows this module to automatically generate a transfer request signal internally. When the DE bits in CHCR_0 to CHCR_15 and the DME bit in DMAOR are set to 1, the transfer begins so long as the TE bits in CHCR_0 to CHCR_15, and the AE and NMIF bits in DMAOR are 0. (2) External Request Mode In this mode a transfer is performed at the request signal (DREQ0) of an external device. Choose one of the modes shown in table 11.4 according to the application system. When the DMA transfer is enabled (DE = 1, DME = 1, TEMASK = 0 or 1 (TE = 0 when TEMASK = 0), AE = 0, NMIF = 0 for level detection; DE = 1, DME = 1, TE = 0, AE = 0, NMIF = 0 for edge detection), DMA transfer is performed upon a request at the DREQ input. Table 11.4 Selecting External Request Modes with the RS Bits RS[3] RS[2] RS[1] RS[0] Address Mode Transfer Source Transfer Destination 0 0 0 0 Dual address mode Any Any 0 0 1 0 Single address mode External memory, memory-mapped external device 1 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 External device with DACK External device with DACK External memory, memory-mapped external device Page 453 of 3088 Section 11 Direct Memory Access Controller SH7268 Group, SH7269 Group Choose to detect DREQ by either the edge or level of the signal input with the DL and DS bits in CHCR_0 as shown in table 11.5. The source of the transfer request does not have to be the data transfer source or destination. When DREQ is detected by a rising/falling edge and DMA transfer is performed in burst mode, the transfer continues until DMATCR reaches 0 by one DMA transfer request. In cycle steal mode, one DMA transfer is performed by one request. Table 11.5 Selecting External Request Detection with DL and DS Bits CHCR DL Bit DS Bit Detection of External Request 0 0 Low-level detection 1 Falling-edge detection 0 High-level detection 1 Rising-edge detection 1 When DREQ is accepted, the DREQ pin enters the request accept disabled state (non-sensitive period). After issuing acknowledge DACK signal for the accepted DREQ, the DREQ pin again enters the request accept enabled state. When DREQ is used by level detection, there are following two cases by the timing to detect the next DREQ after outputting DACK. * Overrun 0: Transfer is terminated after the same number of transfer has been performed as requests. * Overrun 1: Transfer is terminated after transfers have been performed for (the number of requests plus 1) times. The DO bit in CHCR selects this overrun 0 or overrun 1.

Table 11.7 lists the DMA transfer request signals sent from on-chip peripheral modules to this module. If DMA transfer is enabled (DE = 1, DME = 1, TEMASK = 0 or 1 (TE = 0 when TEMASK = 0), AE = 0, and NMIF = 0) in on-chip peripheral module request mode, DMA transfer is started by a transfer request signal. In on-chip peripheral module request mode, there are cases where transfer source or destination is fixed. For details, see table 11.7.

more channels, it selects a channel according to a predetermined priority order. Two modes (fixed mode 1 and fixed mode 2) are selected. In these mode, the priority levels among the channels are as follows: Fixed mode 1: CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 > CH8 > CH9 > CH10 > CH11> CH12> CH13 > CH14 > CH15 Fixed mode 2: CH0 > CH8 > CH1 > CH9 > CH2 > CH10 > CH3 > CH11> CH4 > CH12 > CH5 > CH13 > CH6> CH14 > CH7 > CH15 These are selected by the PR1 and PR0 bits in the DMA operation register (DMAOR). 11.4.4 DMA Transfer Types DMA transfer has two types; single address mode transfer and dual address mode transfer. They depend on the number of bus cycles of access to the transfer source and destination. A data transfer timing depends on the bus mode, which is the cycle steal mode or burst mode. This module supports the transfers shown in table 11.8.

The transfer source and destination can be located externally or internally. SAR Data bus DAR Memory Address bus Direct memory access controller DMA transfer requires two bus cycles because data is read from the transfer source in a data read cycle and written to the transfer destination in a data write cycle. At this time, transfer data is temporarily stored in this module. In the transfer between external memories as shown in figure 11.3, data is read to this module from one external memory in a data read cycle, and then that data is written to the other external memory in a data write cycle. Transfer source module Transfer destination module Data buffer The SAR value is an address, data is read from the transfer source module, and the data is temporarily stored in the direct memory access controller. SAR Data bus DAR Memory Address bus Direct memory access controller First bus cycle Transfer source module Transfer destination module Data buffer The DAR value is an address and the value stored in the data buffer in the direct memory access controller is written to the transfer destination module.

DACK can be output in read cycle or write cycle in dual address mode. The AM bit in the channel control register (CHCR) can specify whether the DACK is output in read cycle or write cycle. Figure 11.4 shows an example of DMA transfer timing in dual address mode.

In this mode, this module performs one DMA transfer in one bus cycle, accessing one of the external devices by outputting the DACK transfer request acknowledge signal to it, and at the same time outputting an address to the other device involved in the transfer. For example, in the case of transfer between external memory and an external device with DACK shown in figure 11.5, when the external device outputs data to the data bus, that data is written to the external memory in the same bus cycle.

In both cases, only the external request signal (DREQ) is used for transfer requests.

Select the mode by the TB bits in the channel control registers (CHCR). (a) Cycle Steal Mode * Normal mode In normal mode of cycle steal, the bus mastership is given to another bus master after a onetransfer-unit (byte, word, longword, or 16-byte unit) DMA transfer. When another transfer request occurs, the bus mastership is obtained from another bus master and a transfer is performed for one transfer unit. When that transfer ends, the bus mastership is passed to another bus master. This is repeated until the transfer end conditions are satisfied. The cycle-steal normal mode can be used for any transfer section; transfer request source, transfer source, and transfer destination. Figure 11.7 shows an example of DMA transfer timing in cycle-steal normal mode. Transfer conditions shown in the figure are; Dual address mode DREQ low level detection DREQ Bus mastership returned to CPU once Bus cycle CPU CPU CPU DMA DMA Read/Write CPU DMA DMA CPU Read/Write Figure 11.7 DMA Transfer Example in Cycle-Steal Normal Mode (Dual Address, DREQ Low Level Detection) * Intermittent Mode 16 and Intermittent Mode 64 In intermittent mode of cycle steal, this module returns the bus mastership to other bus master whenever a unit of transfer (byte, word, longword, or 16 bytes) is completed. If the next transfer request occurs after that, this module obtains the bus mastership from other bus master after waiting for 16 or 64 cycles of B clock. This module then transfers data of one unit and returns the bus mastership to other bus master. These operations are repeated until the transfer end condition is satisfied. It is thus possible to make lower the ratio of bus occupation by DMA transfer than the normal mode of cycle steal. When this module obtains again the bus mastership, DMA transfer may be postponed in case of entry updating due to cache miss. Page 466 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 11 Direct Memory Access Controller The cycle-steal intermittent mode can be used for any transfer section; transfer request source, transfer source, and transfer destination. The bus modes, however, must be cycle steal mode in all channels. Figure 11.8 shows an example of DMA transfer timing in cycle-steal intermittent mode. Transfer conditions shown in the figure are; Dual address mode DREQ low level detection DREQ More than 16 or 64 B clock cycles (depending on the state of bus used by bus master such as CPU) Bus cycle CPU CPU CPU DMA DMA CPU CPU Read/Write DMA DMA CPU Read/Write Figure 11.8 Example of DMA Transfer in Cycle-Steal Intermittent Mode (Dual Address, DREQ Low Level Detection) (b) Burst Mode In burst mode, once this module obtains the bus mastership, it does not release the bus mastership and continues to perform transfer until the transfer end condition is satisfied. In external request mode with low-level detection of the DREQ pin, however, when the DREQ pin is driven high, the bus mastership is passed to another bus master after the DMA transfer request that has already been accepted ends, even if the transfer end conditions have not been satisfied.

External requests, auto requests, and on-chip peripheral module requests are all available. However, in the case of internal module request, along with the exception of the multi-function timer pulse unit 2 and the compare match timer as the transfer request source, the requesting module must be designated as the transfer source or the transfer destination.

Access size permitted for the on-chip peripheral module register functioning as the transfer source or transfer destination. 3. If the transfer request is an external request, channel 0 is only available. 4. External requests, auto requests, and on-chip peripheral module requests are all available. In the case of on-chip peripheral module requests, however, the compare match timer and the multi-function timer pulse unit 2 are only available. 5. In the case of on-chip peripheral module request, only cycle steal except for the CD-ROM decoder, the multi-function timer pulse unit 2, and the compare match timer as the transfer request source. (4) Bus Mode and Channel Priority In priority fixed mode (CH0 > CH1), when channel 1 is transferring data in burst mode and a request arrives for transfer on channel 0, which has higher-priority, the data transfer on channel 0 will begin immediately. In this case, if the transfer on channel 0 is also in burst mode, the transfer on channel 1 will only resume on completion of the transfer on channel 0. When channel 0 is in cycle steal mode, one transfer-unit of data on this channel, which has the higher priority, is transferred. Data is then transferred continuously to channel 1 without releasing the bus. The bus mastership will then switch between the two in this order: channel 0, channel 1, channel 0, channel 1, etc. That is, the CPU cycle after the data transfer in cycle steal mode is replaced with a burst-mode transfer cycle (priority execution of burst-mode cycle). An example of this is shown in figure 11.10. When multiple channels are in burst mode, data transfer on the channel that has the highest priority is given precedence. When DMA transfer is being performed on multiple channels, the bus mastership is not released to another bus-master device until all of the competing burst-mode transfers have been completed.

When a setting is made so that the DMA transfer size is divided into multiple bus cycles and the CS signal is negated between bus cycles, note that DACK and TEND are divided like the CS signal for data alignment as shown in figure 11.16.

When the memory is other than the MPX-I/O, the DACK output is asserted with the same timing as the corresponding CS signal. The TEND output does not depend on the type of memory and is always asserted with the same timing as the corresponding CS signal.

When the input clock is counted using both edges, the input clock period is halved (e.g. P0/4 both edges = P0/2 rising edge). If phase counting mode is used on channels 1 and 2, this setting is ignored and the phase counting mode setting has priority. Internal clock edge selection is valid when the input clock is P0/4 or slower. When P0/1, or the overflow/underflow of another channel is selected for the input clock, although values can be written, counter operation compiles with the initial value. 00: Count at rising edge 01: Count at falling edge 1x: Count at both edges 2 to 0 TPSC[2:0] 000 R/W Time Prescaler 0 to 2 These bits select the TCNT counter clock.

When TGRD is used as a buffer register, TGRD input capture/output compare is not generated in a mode other than complementary PWM. In channels 1 and 2, which have no TGRD, bit 5 is reserved. It is always read as 0 and cannot be modified. 0: TGRB and TGRD operate normally 1: TGRB and TGRD used together for buffer operation 4 BFA 0 R/W Buffer Operation A Specifies whether TGRA is to operate in the normal way, or TGRA and TGRC are to be used together for buffer operation. When TGRC is used as a buffer register, TGRC input capture/output compare is not generated in a mode other than complementary PWM. TGRC compare match is generated when in complementary PWM mode. When compare match for channel 4 occurs during the Tb period in complementary PWM mode, TGFC is set. Therefore, set the TGIEC bit in the timer interrupt enable register 4 (TIER_4) to 0.

When channel 3 is set to reset synchronous PWM mode or complementary PWM mode, the channel 4 settings become ineffective and automatically conform to the channel 3 settings. However, do not set channel 4 to reset synchronous PWM mode or complementary PWM mode. Reset synchronous PWM mode and complementary PWM mode cannot be set for channels 0, 1, and 2.

This module has a total of eight TIOR registers, two each for channels 0, 3, and 4, one each for channels 1 and 2. TIOR should be set while TMDR is set in normal operation, PWM mode, or phase counting mode. The initial output specified by TIOR is valid when the counter is stopped (the CST bit in TSTR is cleared to 0). Note also that, in PWM mode 2, the output at the point at which the counter is cleared to 0 is specified. When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register operates as a buffer register. * TIORH_0, TIOR_1, TIOR_2, TIORH_3, TIORH_4 Bit: 7 6 5 4 3 IOB[3:0] Initial value: 0 R/W: R/W 0 R/W 0 R/W 2 0 1 IOA[3:0] 0 R/W 0 R/W 0 R/W Bit Bit Name Initial Value R/W Description 7 to 4 IOB[3:0] 0000 R/W I/O Control B0 to B3 0 R/W 0 R/W Specify the function of TGRB.

A 16-bit data bus to the bus master enables 16-bit read/writes. 8bit read/write is not possible. Always access in 16-bit units. All registers other than the above registers are 8-bit registers. These are connected to the CPU by a 16-bit data bus, so 16-bit read/writes and 8-bit read/writes are both possible.

TCNT performs up-counting, and is also capable of free-running operation, cycle counting, and external event counting. Each TGR can be used as an input capture register or output compare register. Always select functions for external pins of this module using the general I/O ports. (1) Counter Operation When one of bits CST0 to CST4 in TSTR is set to 1, the TCNT counter for the corresponding channel begins counting. TCNT can operate as a free-running counter, periodic counter, for example. (a) Example of Count Operation Setting Procedure Figure 12.4 shows an example of the count operation setting procedure.

When the relevant bit in TSTR is set to 1 the corresponding TCNT counter starts upcount operation as a free-running counter. When TCNT overflows (from H'FFFF to H'0000), the TCFV bit in TSR is set to 1. If the value of the corresponding TCIEV bit in TIER is 1 at this point, this module requests an interrupt. After overflow, TCNT starts counting up again from H'0000. Figure 12.5 illustrates free-running counter operation. TCNT value H'FFFF H'0000 Time CST bit TCFV Figure 12.5 Free-Running Counter Operation When compare match is selected as the TCNT clearing source, the TCNT counter for the relevant channel performs periodic count operation. The TGR register for setting the period is designated as an output compare register, and counter clearing by compare match is selected by means of bits CCLR0 to CCLR2 in TCR. After the settings have been made, TCNT starts up-count operation as a periodic counter when the corresponding bit in TSTR is set to 1. When the count value matches the value in TGR, the TGF bit in TSR is set to 1 and TCNT is cleared to H'0000. If the value of the corresponding TGIE bit in TIER is 1 at this point, this module requests an interrupt. After a compare match, TCNT starts counting up again from H'0000.

Rising edge, falling edge, or both edges can be selected as the detected edge. For channels 0 and 1, it is also possible to specify another channel's counter input clock or compare match signal as the input capture source. Note: When another channel's counter input clock is used as the input capture input for channels 0 and 1, P0/1 should not be selected as the counter input clock used for input capture input. Input capture will not be generated if P0/1 is selected. (a) Example of Input Capture Operation Setting Procedure Figure 12.10 shows an example of the input capture operation setting procedure. Input selection Select input capture input [1] [1] Designate TGR as an input capture register by means of TIOR, and select rising edge, falling edge, or both edges as the input capture source and input signal edge.

Also, a number of TCNT counters can be cleared simultaneously by making the appropriate setting in TCR (synchronous clearing). Synchronous operation enables TGR to be incremented with respect to a single time base. Channels 0 to 4 can all be designated for synchronous operation. (1) Example of Synchronous Operation Setting Procedure Figure 12.12 shows an example of the synchronous operation setting procedure.

In this example, synchronous operation and PWM mode 1 have been designated for channels 0 to 2, TGRB_0 compare match has been set as the channel 0 counter clearing source, and synchronous clearing has been set for the channel 1 and 2 counter clearing source. Three-phase PWM waveforms are output from pins TIOC0A, TIOC1A, and TIOC2A. At this time, synchronous presetting, and synchronous clearing by TGRB_0 compare match, are performed for channel 0 to 2 TCNT counters, and the data set in TGRB_0 is used as the PWM cycle. For details of PWM modes, see section 12.4.5, PWM Modes.

In channel 0, TGRF can also be used as a buffer register. Buffer operation differs depending on whether TGR has been designated as an input capture register or as a compare match register. Note: TGRE_0 cannot be designated as an input capture register and can only operate as a compare match register. Table 12.41 shows the register combinations used in buffer operation.

The settings used in this example are TCNT clearing by compare match B, 1 output at compare match A, and 0 output at compare match B. In this example, the TTSA bit in TBTM is cleared to 0. As buffer operation has been set, when compare match A occurs the output changes and the value in buffer register TGRC is simultaneously transferred to timer general register TGRA. This operation is repeated each time that compare match A occurs. For details of PWM modes, see section 12.4.5, PWM Modes.

Counter clearing by TGRA input capture has been set for TCNT, and both rising and falling edges have been selected as the TIOCA pin input capture input edge. As buffer operation has been set, when the TCNT value is stored in TGRA upon the occurrence of input capture A, the value previously stored in TGRA is simultaneously transferred to TGRC.

Either compare match (initial setting) or TCNT clearing can be selected for the transfer timing. TCNT clearing as transfer timing is one of the following cases. * When TCNT overflows (H'FFFF to H'0000) * When H'0000 is written to TCNT during counting * When TCNT is cleared to H'0000 under the condition specified in the CCLR2 to CCLR0 bits in TCR Note: TBTM must be modified only while TCNT stops. Figure 12.19 shows an operation example in which PWM mode 1 is designated for channel 0 and buffer operation is designated for TGRA_0 and TGRC_0. The settings used in this example are TCNT_0 clearing by compare match B, 1 output at compare match A, and 0 output at compare match B. The TTSA bit in TBTM_0 is set to 1.

This function works by counting the channel 1 counter clock upon overflow/underflow of TCNT_2 as set in bits TPSC0 to TPSC2 in TCR. Underflow occurs only when the lower 16-bit TCNT is in phase-counting mode. Table 12.42 shows the register combinations used in cascaded operation. Note: When phase counting mode is set for channel 1, the counter clock setting is invalid and the counters operates independently in phase counting mode. Table 12.42 Cascaded Combinations Combination Upper 16 Bits Lower 16 Bits Channels 1 and 2 TCNT_1 TCNT_2 For simultaneous input capture of TCNT_1 and TCNT_2 during cascaded operation, additional input capture input pins can be specified by the input capture control register (TICCR). The edge detection that is the condition for input capture uses a signal representing the logical OR of the original input pin and the added input pins. For details, see (4) Cascaded Operation Example (c).

The output level can be selected as 0, 1, or toggle output in response to a compare match of each TGR. TGR registers settings can be used to output a PWM waveform in the range of 0% to 100% duty. Designating TGR compare match as the counter clearing source enables the period to be set in that register. All channels can be designated for PWM mode independently. Synchronous operation is also possible. There are two PWM modes, as described below. * PWM mode 1 PWM output is generated from the TIOCA and TIOCC pins by pairing TGRA with TGRB and TGRC with TGRD. The output specified by bits IOA0 to IOA3 and IOC0 to IOC3 in TIOR is output from the TIOCA and TIOCC pins at compare matches A and C, and the output specified by bits IOB0 to IOB3 and IOD0 to IOD3 in TIOR is output at compare matches B and D. The initial output value is the value set in TGRA or TGRC. If the set values of paired TGRs are identical, the output value does not change when a compare match occurs. In PWM mode 1, a maximum 8-phase PWM output is possible. * PWM mode 2 PWM output is generated using one TGR as the cycle register and the others as duty registers. The output specified in TIOR is performed by means of compare matches. Upon counter clearing by a cycle register compare match, the output value of each pin is the initial value set in TIOR. If the set values of the cycle and duty registers are identical, the output value does not change when a compare match occurs. In PWM mode 2, a maximum 8-phase PWM output is possible in combination use with synchronous operation. The correspondence between PWM output pins and registers is shown in table 12.44.

This mode can be set for channels 1 and 2. When phase counting mode is set, an external clock is selected as the counter input clock and TCNT operates as an up/down-counter regardless of the setting of bits TPSC0 to TPSC2 and bits CKEG0 and CKEG1 in TCR. However, the functions of bits CCLR0 and CCLR1 in TCR, and of TIOR, TIER, and TGR, are valid, and input capture/compare match and interrupt functions can be used. This can be used for two-phase encoder pulse input. If overflow occurs when TCNT is counting up, the TCFV flag in TSR is set; if underflow occurs when TCNT is counting down, the TCFU flag is set. The TCFD bit in TSR is the count direction flag. Reading the TCFD flag reveals whether TCNT is counting up or down. Table 12.45 shows the correspondence between external clock pins and channels.

Channel 1 is set to phase counting mode 1, and the encoder pulse A-phase and B-phase are input to TCLKA and TCLKB. Channel 0 operates with TCNT counter clearing by TGRC_0 compare match; TGRA_0 and TGRC_0 are used for the compare match function and are set with the speed control period and position control period. TGRB_0 is used for input capture, with TGRB_0 and TGRD_0 operating in buffer mode. The channel 1 counter input clock is designated as the TGRB_0 input capture source, and the pulse widths of 2-phase encoder 4-multiplication pulses are detected. TGRA_1 and TGRB_1 for channel 1 are designated for input capture, and channel 0 TGRA_0 and TGRC_0 compare matches are selected as the input capture source and store the up/down-counter values for the control periods. This procedure enables the accurate detection of position and speed.

Figure 12.39 illustrates counter operation in complementary PWM mode, and figure 12.40 shows an example of complementary PWM mode operation. (a) Counter Operation In complementary PWM mode, three counters--TCNT_3, TCNT_4, and TCNTS--perform up/down-count operations. TCNT_3 is automatically initialized to the value set in TDDR when complementary PWM mode is selected and the CST bit in TSTR is 0. When the CST bit is set to 1, TCNT_3 counts up to the value set in TGRA_3, then switches to down-counting when it matches TGRA_3. When the TCNT3 value matches TDDR, the counter switches to up-counting, and the operation is repeated in this way. TCNT_4 is initialized to H'0000. When the CST bit is set to 1, TCNT4 counts up in synchronization with TCNT_3, and switches to down-counting when it matches TCDR. On reaching H'0000, TCNT4 switches to up-counting, and the operation is repeated in this way. TCNTS is a read-only counter. It need not be initialized. When TCNT_3 matches TCDR during TCNT_3 and TCNT_4 up/down-counting, down-counting is started, and when TCNTS matches TCDR, the operation switches to up-counting. When TCNTS matches TGRA_3, it is cleared to H'0000. When TCNT_4 matches TDDR during TCNT_3 and TCNT_4 down-counting, up-counting is started, and when TCNTS matches TDDR, the operation switches to down-counting. When TCNTS reaches H'0000, it is set with the value in TGRA_3. TCNTS is compared with the compare register and temporary register in which the PWM duty is set during the count operation only.

Figure 12.40 shows an example of complementary PWM mode operation. The registers which are constantly compared with the counters to perform PWM output are TGRB_3, TGRA_4, and TGRB_4. When these registers match the counter, the value set in bits OLSN and OLSP in the timer output control register (TOCR) is output. The buffer registers for these compare registers are TGRD_3, TGRC_4, and TGRD_4. Between a buffer register and compare register there is a temporary register. The temporary registers cannot be accessed by the CPU. Data in a compare register is changed by writing the new data to the corresponding buffer register. The buffer registers can be read or written at any time. The data written to a buffer register is constantly transferred to the temporary register in the Ta interval. Data is not transferred to the temporary register in the Tb interval. Data written to a buffer register in this interval is transferred to the temporary register at the end of the Tb interval. The value transferred to a temporary register is transferred to the compare register when TCNTS for which the Tb interval ends matches TGRA_3 when counting up, or H'0000 when counting down. The timing for transfer from the temporary register to the compare register can be selected with bits MD3 to MD0 in the timer mode register (TMDR). Figure 12.40 shows an example in which the mode is selected in which the change is made in the trough.

In this interval, therefore, there are two compare match registers for one-phase output, with the compare register containing the pre-change data, and the temporary register containing the new data. In this interval, the three counters--TCNT_3, TCNT_4, and TCNTS-- and two registers--compare register and temporary register--are compared, and PWM output controlled accordingly.

In addition, there is a register that specifies whether to generate dead time (it should be used only when dead time generation should be disabled). Before setting complementary PWM mode with bits MD3 to MD0 in the timer mode register (TMDR), the following initial register values must be set. TGRC_3 operates as the buffer register for TGRA_3, and should be set with 1/2 the PWM carrier cycle + dead time Td. The timer cycle buffer register (TCBR) operates as the buffer register for the timer cycle data register (TCDR), and should be set with 1/2 the PWM carrier cycle. Set dead time Td in the timer dead time data register (TDDR). When dead time is not needed, the TDER bit in the timer dead time enable register (TDER) should be cleared to 0, TGRC_3 and TGRA_3 should be set to 1/2 the PWM carrier cycle + 1, and TDDR should be set to 1. Set the respective initial PWM duty values in buffer registers TGRD_3, TGRC_4, and TGRD_4. The values set in the five buffer registers excluding TDDR are transferred simultaneously to the corresponding compare registers when complementary PWM mode is set. Set TCNT_4 to H'0000 before setting complementary PWM mode.

The output level can be set for each of the three positive phases and three negative phases of 6phase output. Complementary PWM mode should be cleared before setting or changing output levels. (e) Dead Time Setting In complementary PWM mode, PWM pulses are output with a non-overlapping relationship between the positive and negative phases. This non-overlap time is called the dead time. The non-overlap time is set in the timer dead time data register (TDDR). The value set in TDDR is used as the TCNT_3 counter start value, and creates non-overlap between TCNT_3 and TCNT_4. Complementary PWM mode should be cleared before changing the contents of TDDR. (f) Dead Time Suppressing Dead time generation is suppressed by clearing the TDER bit in the timer dead time enable register (TDER) to 0. TDER can be cleared to 0 only when 0 is written to it after reading TDER = 1. TGRA_3 and TGRC_3 should be set to 1/2 PWM carrier cycle + 1 and the timer dead time data register (TDDR) should be set to 1. By the above settings, PWM waveforms without dead time can be obtained. Figure 12.41 shows an example of operation without dead time.

The settings should be made so as to achieve the following relationship between these two registers: With dead time: TGRA_3 set value = TCDR set value + TDDR set value Without dead time: TGRA_3 set value = TCDR set value + 1 The TGRA_3 and TCDR settings are made by setting the values in buffer registers TGRC_3 and TCBR. The values set in TGRC_3 and TCBR are transferred simultaneously to TGRA_3 and TCDR in accordance with the transfer timing selected with bits MD3 to MD0 in the timer mode register (TMDR). The updated PWM cycle is reflected from the next cycle when the data update is performed at the crest, and from the current cycle when performed in the trough. Figure 12.42 illustrates the operation when the PWM cycle is updated at the crest. See (h) Register Data Updating, for the method of updating the data in each buffer register.

The update data can be written to the buffer register at any time. There are five PWM duty and carrier cycle registers that have buffer registers and can be updated during operation. There is a temporary register between each of these registers and its buffer register. When subcounter TCNTS is not counting, if buffer register data is updated, the temporary register value is also rewritten. Transfer is not performed from buffer registers to temporary registers when TCNTS is counting; in this case, the value written to a buffer register is transferred after TCNTS halts. The temporary register value is transferred to the compare register at the data update timing set with bits MD3 to MD0 in the timer mode register (TMDR). Figure 12.43 shows an example of data updating in complementary PWM mode. This example shows the mode in which data updating is performed at both the counter crest and trough. When rewriting buffer register data, a write to TGRD_4 must be performed at the end of the update. Data transfer from the buffer registers to the temporary registers is performed simultaneously for all five registers after the write to TGRD_4. A write to TGRD_4 must be performed after writing data to the registers to be updated, even when not updating all five registers, or when updating the TGRD_4 data. In this case, the data written to TGRD_4 should be the same as the data prior to the write operation.

This initial output is the PWM pulse non-active level, and is output from when complementary PWM mode is set with the timer mode register (TMDR) until TCNT_4 exceeds the value set in the dead time register (TDDR). Figure 12.44 shows an example of the initial output in complementary PWM mode. An example of the waveform when the initial PWM duty value is smaller than the TDDR value is shown in figure 12.45.

This non-overlap time is called the dead time. A PWM waveform is generated by output of the output level selected in the timer output control register in the event of a compare-match between a counter and compare register. While TCNTS is counting, compare register and temporary register values are simultaneously compared to create consecutive PWM pulses from 0 to 100%. The relative timing of on and off compare-match occurrence may vary, but the compare-match that turns off each phase takes precedence to secure the dead time and ensure that the positive phase and negative phase on times do not overlap. Figures 12.46 to 12.48 show examples of waveform generation in complementary PWM mode. The positive phase/negative phase off timing is generated by a compare-match with the solid-line counter, and the on timing by a compare-match with the dotted-line counter operating with a delay of the dead time behind the solid-line counter. In the T1 period, compare-match a that turns off the negative phase has the highest priority, and compare-matches occurring prior to a are ignored. In the T2 period, compare-match c that turns off the positive phase has the highest priority, and compare-matches occurring prior to c are ignored. In normal cases, compare-matches occur in the order a b c d (or c d a' b'), as shown in figure 12.46. If compare-matches deviate from the a b c d order, since the time for which the negative phase is off is less than twice the dead time, the figure shows the positive phase is not being turned on. If compare-matches deviate from the c d a' b' order, since the time for which the positive phase is off is less than twice the dead time, the figure shows the negative phase is not being turned on. If compare-match c occurs first following compare-match a, as shown in figure 12.47, comparematch b is ignored, and the negative phase is turned off by compare-match d. This is because turning off of the positive phase has priority due to the occurrence of compare-match c (positive phase off timing) before compare-match b (positive phase on timing) (consequently, the waveform does not change since the positive phase goes from off to off). Similarly, in the example in figure 12.48, compare-match a' with the new data in the temporary register occurs before compare-match c, but other compare-matches occurring up to c, which turns off the positive phase, are ignored. As a result, the negative phase is not turned on. Thus, in complementary PWM mode, compare-matches at turn-off timings take precedence, and turn-on timing compare-matches that occur before a turn-off timing compare-match are ignored.

Figures 12.49 to 12.53 show output examples. 100% duty output is performed when the compare register value is set to H'0000. The waveform in this case has a positive phase with a 100% on-state. 0% duty output is performed when the compare register value is set to the same value as TGRA_3. The waveform in this case has a positive phase with a 100% off-state. On and off compare-matches occur simultaneously, but if a turn-on compare-match and turn-off compare-match for the same phase occur simultaneously, both compare-matches are ignored and the waveform does not change. (l) Toggle Output Synchronized with PWM Cycle In complementary PWM mode, toggle output can be performed in synchronization with the PWM carrier cycle by setting the PSYE bit to 1 in the timer output control register (TOCR). An example of a toggle output waveform is shown in figure 12.54. This output is toggled by a compare-match between TCNT_3 and TGRA_3 and a compare-match between TCNT4 and H'0000. The output pin for this toggle output is the TIOC3A pin. The initial output is 1.

Figure 12.55 illustrates the operation. Use of this function enables counter clearing and restarting to be performed by means of an external signal.

Initial output suppression is applicable only when synchronous clearing occurs in the Tb interval at the trough as indicated by (10) or (11) in figure 12.56. When synchronous clearing occurs outside that interval, the initial value specified by the OLS bits in TOCR is output. Even in the Tb interval at the trough, if synchronous clearing occurs in the initial value output period (indicated by (1) in figure 12.56) immediately after the counters start operation, initial value output is not suppressed. When using the initial output suppression function, make sure to set compare registers TGRB_3, TGRA_4, and TGRB_4 to a value twice or more the setting of dead time data register TDDR. If synchronous clearing occurs with the compare registers set to a value less than twice the setting of TDDR, the PWM output dead time may be too short (or nonexistent) or illegal active-level PWM negative-phase output may occur during the initial output suppression interval. For details, see section 12.7.23, Notes on Output Waveform Control During Synchronous Counter Clearing in Complementary PWM Mode.

Figures 12.63 to 12.66 show examples of brushless DC motor drive waveforms created using TGCR. When output phase switching for a 3-phase brushless DC motor is performed by means of external signals detected with a Hall element, etc., clear the FB bit in TGCR to 0. In this case, the external signals indicating the polarity position are input to channel 0 timer input pins TIOC0A, TIOC0B, and TIOC0C (set with the general I/O ports). When an edge is detected at pin TIOC0A, TIOC0B, or TIOC0C, the output on/off state is switched automatically. When the FB bit is 1, the output on/off state is switched when the UF, VF, or WF bit in TGCR is cleared to 0 or set to 1. The drive waveforms are output from the complementary PWM mode 6-phase output pins. With this 6-phase output, in the case of on output, it is possible to use complementary PWM mode output and perform chopping output by setting the N bit or P bit to 1. When the N bit or P bit is 0, level output is selected. The 6-phase output active level (on output level) can be set with the OLSN and OLSP bits in the timer output control register (TOCR) regardless of the setting of the N and P bits.

When start requests using a TGRA_3 compare-match are specified, A/D conversion can be started at the crest of the TCNT_3 count. A/D converter start requests can be set by setting the TTGE bit to 1 in the timer interrupt enable register (TIER). To issue an A/D converter start request at a TCNT_4 underflow (trough), set the TTGE2 bit in TIER_4 to 1.

Transfers from a buffer register to a temporary register or a compare register can be skipped in coordination with interrupt skipping by making settings in the timer buffer transfer register (TBTER). For the linkage with buffer registers, refer to description (c), Buffer Transfer Control Linked with Interrupt Skipping, below. A/D converter start requests generated by the A/D converter start request delaying function can also be skipped in coordination with interrupt skipping by making settings in the timer A/D converter request control register (TADCR). For the linkage with the A/D converter start request delaying function, refer to section 12.4.9, A/D Converter Start Request Delaying Function. The setting of the timer interrupt skipping setting register (TITCR) must be done while the TGIA_3 and TCIV_4 interrupt requests are disabled by the settings of TIER_3 and TIER_4 along with under the conditions in which TGFA_3 and TCFV_4 flag settings by compare match never occur. Before changing the skipping count, be sure to clear the T3AEN and T4VEN bits to 0 to clear the skipping counter. (a) Example of Interrupt Skipping Operation Setting Procedure Figure 12.67 shows an example of the interrupt skipping operation setting procedure. Figure 12.68 shows the periods during which interrupt skipping count can be changed. [1] Set bits T3AEN and T4VEN in the timer interrupt skipping set register (TITCR) to 0 to clear the skipping counter.

Note: The setting of TITCR must be done while the TGIA_3 and TCIV_4 interrupt requests are disabled by the settings of TIER_3 and TIER_4 along with under the conditions in which TGFA_3 and TCFV_4 flag settings by compare match never occur. Before changing the skipping count, be sure to clear the T3AEN and T4VEN bits to 0 to clear the skipping counter.

Figure 12.70 shows an example of operation when buffer transfer is suppressed (BTE1 = 0 and BTE0 = 1). While this setting is valid, data is not transferred from the buffer register to the temporary register. Figure 12.71 shows an example of operation when buffer transfer is linked with interrupt skipping (BTE1 = 1 and BET0 = 0). While this setting is valid, data is not transferred from the buffer register to the temporary register outside the buffer transfer-enabled period. Depending on the rewrite timing from the interrupt generation to the buffer register, there are two types of the transfer timing such as from the buffer register to the temporary register and from the temporary register to the general register. Note that the buffer transfer-enabled period depends on the T3AEN and T4VEN bit settings in the timer interrupt skipping set register (TITCR). Figure 12.72 shows the relationship between the T3AEN and T4VEN bit settings in TITCR and buffer transfer-enabled period. Note: This function must always be used in combination with interrupt skipping. When interrupt skipping is disabled (the T3AEN and T4VEN bits in the timer interrupt skipping set register (TITCR) are cleared to 0 or the skipping count set bits (3ACOR and 4VCOR) in TITCR are cleared to 0), make sure that buffer transfer is not linked with interrupt skipping (clear the BTE1 bit in the timer buffer transfer set register (TBTER) to 0). If buffer transfer is linked with interrupt skipping while interrupt skipping is disabled, buffer transfer is never performed.

(a) Register and counter miswrite prevention function With the exception of the buffer registers, which can be rewritten at any time, access by the CPU can be enabled or disabled for the mode registers, control registers, compare registers, and counters used in complementary PWM mode by means of the RWE bit in the timer read/write enable register (TRWER). The applicable registers are some (21 in total) of the registers in channels 3 and 4 shown in the following: * TCR_3 and TCR_4, TMDR_3 and TMDR_4, TIORH_3 and TIORH_4, TIORL_3 and TIORL_4, TIER_3 and TIER_4, TCNT_3 and TCNT_4, TGRA_3 and TGRA_4, TGRB_3 and TGRB_4, TOER, TOCR, TGCR, TCDR, and TDDR. This function enables miswriting due to CPU runaway to be prevented by disabling CPU access to the mode registers, control registers, and counters. When the applicable registers are read in the access-disabled state, undefined values are returned. Writing to these registers is ignored.

The A/D converter start request delaying function compares TCNT_4 with TADCORA_4 or TADCORB_4, and when their values match, the function issues a respective A/D converter start request (TRG4AN or TRG4BN). A/D converter start requests (TRG4AN and TRG4BN) can be skipped in coordination with interrupt skipping by setting the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in TADCR. * Example of Procedure for Specifying A/D Converter Start Request Delaying Function Figure 12.73 shows an example of procedure for specifying the A/D converter start request delaying function. [1] Set the cycle in the timer A/D converter start request cycle buffer register (TADCOBRA_4 or TADCOBRB_4) and timer A/D converter start request cycle register (TADCORA_4 or TADCORB_4). (The same initial value must be specified in the cycle buffer register and cycle register.)

Notes: 1. Perform TADCR setting while TCNT_4 is stopped. 2. Do not set BF1 to 1 when complementary PWM mode is not selected. 3. Do not set ITA3AE, ITA4VE, ITB3AE, ITB4VE, DT4AE, or DT4BE to 1 when complementary PWM mode is not selected.

Data is transferred from the buffer registers to the respective cycle set registers at the timing selected with the BF1 and BF0 bits in the timer A/D converter start request control register (TADCR_4). * A/D Converter Start Request Delaying Function Linked with Interrupt Skipping A/D converter start requests (TRG4AN and TRG4BN) can be issued in coordination with interrupt skipping by making settings in the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in the timer A/D converter start request control register (TADCR). Figure 12.75 shows an example of A/D converter start request signal (TRG4AN) operation when TRG4AN output is enabled during TCNT_4 up counting and down counting and A/D converter start requests are linked with interrupt skipping. Figure 12.76 shows another example of A/D converter start request signal (TRG4AN) operation when TRG4AN output is enabled during TCNT_4 up counting and A/D converter start requests are linked with interrupt skipping.

Each interrupt source has its own status flag and enable/disabled bit, allowing the generation of interrupt request signals to be enabled or disabled individually. When an interrupt request is generated, the corresponding status flag in TSR is set to 1. If the corresponding enable/disable bit in TIER is set to 1 at this time, an interrupt is requested. The interrupt request is cleared by clearing the status flag to 0. Relative channel priorities can be changed by the interrupt controller, however the priority order within a channel is fixed. For details, see section 7, Interrupt Controller. Table 12.55 lists the interrupt sources of this module.

The relative channel priorities can be changed by the interrupt controller. (1) Input Capture/Compare Match Interrupt An interrupt is requested if the TGIE bit in TIER is set to 1 when the TGF flag in TSR is set to 1 by the occurrence of a TGR input capture/compare match on a particular channel. The interrupt request is cleared by clearing the TGF flag to 0. This module has eighteen input capture/compare match interrupts, six for channel 0, four each for channels 3 and 4, and two each for channels 1 and 2. The TGFE_0 and TGFF_0 flags in channel 0 are not set by the occurrence of an input capture. (2) Overflow Interrupt An interrupt is requested if the TCIEV bit in TIER is set to 1 when the TCFV flag in TSR is set to 1 by the occurrence of TCNT overflow on a channel. The interrupt request is cleared by clearing the TCFV flag to 0. This module has five overflow interrupts, one for each channel. Page 628 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (3) Section 12 Multi-Function Timer Pulse Unit 2 Underflow Interrupt An interrupt is requested if the TCIEU bit in TIER is set to 1 when the TCFU flag in TSR is set to 1 by the occurrence of TCNT underflow on a channel. The interrupt request is cleared by clearing the TCFU flag to 0. This module has two underflow interrupts, one each for channels 1 and 2. 12.5.2 Activation of Direct Memory Access Controller The direct memory access controller can be activated by the TGRA input capture/compare match interrupt in each channel. For details, see section 11, Direct Memory Access Controller. In this module, a total of five TGRA input capture/compare match interrupts can be used as direct memory access controller activation sources, one each for channels 0 to 4. 12.5.3 A/D Converter Activation The A/D converter can be activated by one of the following three methods in this module. Table 12.56 shows the relationship between interrupt sources and A/D converter start request signals. (1) A/D Converter Activation by TGRA Input Capture/Compare Match or at TCNT_4 Trough in Complementary PWM Mode The A/D converter can be activated by the occurrence of a TGRA input capture/compare match in each channel. In addition, if complementary PWM operation is performed while the TTGE2 bit in TIER_4 is set to 1, the A/D converter can be activated at the trough of TCNT_4 count (TCNT_4 = H'0000). A/D converter start request signal TRGAN is issued to the A/D converter under either one of the following conditions. * When the TGFA flag in TSR is set to 1 by the occurrence of a TGRA input capture/compare match on a particular channel while the TTGE bit in TIER is set to 1 * When the TCNT_4 count reaches the trough (TCNT_4 = H'0000) during complementary PWM operation while the TTGE2 bit in TIER_4 is set to 1 When either condition is satisfied, if A/D converter start signal TRGAN from this module is selected as the trigger in the A/D converter, A/D conversion will start. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 629 of 3088 Section 12 Multi-Function Timer Pulse Unit 2 (2) SH7268 Group, SH7269 Group A/D Converter Activation by Compare Match between TCNT_0 and TGRE_0 The A/D converter can be activated by generating A/D converter start request signal TRG0N when a compare match occurs between TCNT_0 and TGRE_0 in channel 0. When the TGFE flag in TSR2_0 is set to 1 by the occurrence of a compare match between TCNT_0 and TGRE_0 in channel 0 while the TTGE2 bit in TIER2_0 is set to 1, A/D converter start request TGR0N is issued to the A/D converter. If A/D converter start signal TGR0N from this module is selected as the trigger in the A/D converter, A/D conversion will start. (3) A/D Converter Activation by A/D Converter Start Request Delaying Function The A/D converter can be activated by generating A/D converter start request signal TRG4AN or TRG4BN when the TCNT_4 count matches the TADCORA or TADCORB value if the UT4AE, DT4AE, UT4BE, or DT4BE bit in the A/D converter start request control register (TADCR) is set to 1. For details, refer to section 12.4.9, A/D Converter Start Request Delaying Function. A/D conversion will start if A/D converter start signal TRG4AN from this module is selected as the trigger in the A/D converter when TRG4AN is generated or if TRG4BN from this module is selected as the trigger in the A/D converter when TRG4BN is generated.

The initial setting is for the operation to be halted. Register access is enabled by clearing module standby mode. For details, refer to section 49, Power-Down Modes. 12.7.2 Input Clock Restrictions The input clock pulse width must be at least 1.5 states in the case of single-edge detection, and at least 2.5 states in the case of both-edge detection. This module will not operate properly at narrower pulse widths. In phase counting mode, the phase difference and overlap between the two input clocks must be at least 1.5 states, and the pulse width must be at least 2.5 states.

At this point, if there is match with TGRA_1 and the TCNT_1 value, a compare signal is issued. Furthermore, when the TCNT_1 count clock is selected as the input capture source of channel 0, TGRA_0 to D_0 carry out the input capture operation. In addition, when the compare match/input capture is selected as the input capture source of TGRB_1, TGRB_1 carries out input capture operation. The timing is shown in figure 12.107. For cascade connections, be sure to synchronize settings for channels 1 and 2 when setting TCNT clearing.

In complementary PWM mode, channel 3 and channel 4 buffers operate in accordance with bit settings BFA and BFB of TMDR_3. When TMDR_3's BFA bit is set to 1, TGRC_3 functions as a buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer register for TGRA_4, and TCBR functions as the TCDR's buffer register.

The TIOC4C pin will be unable to produce its waveform output if the BFA bit of TMDR_4 is set to 1. In reset sync PWM mode, the channel 3 and channel 4 buffers operate in accordance with the BFA and BFB bit settings of TMDR_3. For example, if the BFA bit of TMDR_3 is set to 1, TGRC_3 functions as the buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer register for TGRA_4. The TGFC bit and TGFD bit of TSR_3 and TSR_4 are not set when TGRC_3 and TGRD_3 are operating as buffer registers. Figure 12.109 shows an example of operations for TGR_3, TGR_4, TIOC3, and TIOC4, with TMDR_3's BFA and BFB bits set to 1, and TMDR_4's BFA and BFB bits set to 0.

At this point, TCNT_4's count clock source and count edge obey the TCR_3 setting. In reset synchronous PWM mode, with cycle register TGRA_3's set value at H'FFFF, when specifying TGR3A compare-match for the counter clear source, TCNT_3 and TCNT_4 count up to H'FFFF, then a compare-match occurs with TGRA_3, and TCNT_3 and TCNT_4 are both cleared. At this point, TSR's overflow flag TCFV bit is not set. Figure 12.110 shows a TCFV bit operation example in reset synchronous PWM mode with a set value for cycle register TGRA_3 of H'FFFF, when a TGRA_3 compare-match has been specified without synchronous setting for the counter clear source.

When making a transition from normal operation to reset-synchronized PWM mode, write H'11 to registers TIORH_3, TIORL_3, TIORH_4, and TIORL_4 to initialize the output pins to low level output, then set an initial register value of H'00 before making the mode transition. When making a transition from PWM mode 1 to reset-synchronized PWM mode, first switch to normal operation, then initialize the output pins to low level output and set an initial register value of H'00 before making the transition to reset-synchronized PWM mode. Page 656 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 12 Multi-Function Timer Pulse Unit 2 12.7.20 Output Level in Complementary PWM Mode and Reset-Synchronized PWM Mode When channels 3 and 4 are in complementary PWM mode or reset-synchronized PWM mode, the PWM waveform output level is set with the OLSP and OLSN bits in the timer output control register (TOCR). In the case of complementary PWM mode or reset-synchronized PWM mode, TIOR should be set to H'00. 12.7.21 Interrupts in Module Standby Mode If module standby mode is entered when an interrupt has been requested, it will not be possible to clear the CPU interrupt source or the direct memory access controller activation source. Interrupts should therefore be disabled before entering module standby mode. 12.7.22 Simultaneous Capture of TCNT_1 and TCNT_2 in Cascade Connection When timer counters 1 and 2 (TCNT_1 and TCNT_2) are operated as a 32-bit counter in cascade connection, the cascade counter value cannot be captured successfully even if input-capture input is simultaneously done to TIOC1A and TIOC2A or to TIOC1B and TIOC2B. This is because the input timing of TIOC1A and TIOC2A or of TIOC1B and TIOC2B may not be the same when external input-capture signals to be input into TCNT_1 and TCNT_2 are taken in synchronization with the internal clock. For example, TCNT_1 (the counter for upper 16 bits) does not capture the count-up value by overflow from TCNT_2 (the counter for lower 16 bits) but captures the count value before the count-up. In this case, the values of TCNT_1 = H'FFF1 and TCNT_2 = H'0000 should be transferred to TGRA_1 and TGRA_2 or to TGRB_1 and TGRB_2, but the values of TCNT_1 = H'FFF0 and TCNT_2 = H'0000 are erroneously transferred.

Waveform output is possible in all of these modes. * Normal mode (channels 0 to 4) * PWM mode 1 (channels 0 to 4) * PWM mode 2 (channels 0 to 2) * Phase counting modes 1 to 4 (channels 1 and 2) * Complementary PWM mode (channels 3 and 4) * Reset-synchronized PWM mode (channels 3 and 4) The output pin initialization method for each of these modes is described in this section. 12.8.2 Reset Start Operation The output pins of this module (TIOC*) are initialized low by a reset and in standby mode. Since the pin functions are selected using the general I/O ports, when the general I/O port is set, the pin states at that point are output to the ports. When this module output is selected by the general I/O port immediately after a reset, the initial output level, low, is output directly at the port. When the active level is low, the system will operate at this point, and therefore the general I/O port setting should be made after the initialization of the output pins is completed. Note: Channel number and port notation are substituted for *.

Cutoff is performed by switching the pin output to port output with the general I/O port and outputting the inverse of the active level. The pin initialization procedures for re-setting due to an error during operation, etc., and the procedures for restarting in a different mode after re-setting, are shown below. This module has six operating modes, as stated above. There are thus 36 mode transition combinations, but some transitions are not available with certain channel and mode combinations. Possible mode transition combinations are shown in table 12.57.

If initialization is required, carry it out in normal mode, then switch to PWM mode 1. * In PWM mode 2, since a waveform is not output to the cycle register pin, setting TIOR will not initialize the pins. If initialization is required, carry it out in normal mode, then switch to PWM mode 2. * In normal mode or PWM mode 2, if TGRC and TGRD operate as buffer registers, setting TIOR will not initialize the buffer register pins. If initialization is required, clear buffer mode, carry out initialization, then set buffer mode again. * In PWM mode 1, if either TGRC or TGRD operates as a buffer register, setting TIOR will not initialize the TGRC pin. To initialize the TGRC pin, clear buffer mode, carry out initialization, then set buffer mode again. * When making a transition to a mode (CPWM, RPWM) in which the pin output level is selected by the timer output control register (TOCR) setting, switch to normal mode and perform initialization with TIOR, then restore TIOR to its initial value, and temporarily disable channel 3 and 4 output with the timer output master enable register (TOER). Then operate the unit in accordance with the mode setting procedure (TOCR setting, TMDR setting, TOER setting). Note: Channel number is substituted for * indicated in this article. Pin initialization procedures are described below for the numbered combinations in table 12.57. The active level is assumed to be low.

When the counter input clock is selected with bits CKS[1:0] in CMCSR, and the STR bit in CMSTR is set to 1, CMCNT starts counting using the selected clock. When the value in CMCNT and the value in compare match constant register (CMCOR) match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1. CMCNT is initialized to H'0000 by clearing any channels of the counter start bit from 1 to 0 in the compare match timer start register (CMSTR).

When the values in CMCNT and CMCOR match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1. When the CMIE bit in CMCSR is set to 1 at this time, a compare match interrupt (CMI) is requested. CMCNT then starts counting up again from H'0000.

When both the compare match flag (CMF) and the interrupt enable bit (CMIE) are set to 1, the corresponding interrupt request is output. When the interrupt is used to activate a CPU interrupt, the priority of channels can be changed by the interrupt controller settings. For details, see section 7, Interrupt Controller. Clear the CMF bit to 0 by the user exception handling routine. If this operation is not carried out, another interrupt will be generated. By setting the interrupt controller, the direct memory access controller can be activated when a compare match interrupt is requested. In this case, an interrupt is not issued to the CPU. If the setting to activate the direct memory access controller has not been made, an interrupt request is sent to the CPU. The CMF bit is automatically cleared to 0 when data is transferred by the direct memory access controller. 13.4.2 Timing of Compare Match Flag Setting When CMCOR and CMCNT match, a compare match signal is generated at the last state in which the values match (the timing when the CMCNT value is updated to H'0000) and the CMF bit in CMCSR is set to 1. That is, after a match between CMCOR and CMCNT, the compare match signal is not generated until the next CMCNT counter clock input. Figure 13.4 shows the timing of CMF bit setting.

This module can simultaneously generate an internal reset signal for the entire LSI. This module is a single channel timer that counts up the clock oscillation settling period when the system leaves software standby mode. It can also be used as a general watchdog timer or interval timer. 14.1 Features * Can be used to ensure the clock oscillation settling time This module is used in leaving software standby mode. * Can switch between watchdog timer mode and interval timer mode. * Outputs WDTOVF signal in watchdog timer mode When the counter overflows in watchdog timer mode, the WDTOVF signal is output externally.

Watchdog Timer Counter (WTCNT) WTCNT is an 8-bit readable/writable register that is incremented by cycles of the selected clock signal. When an overflow occurs, it generates a watchdog timer overflow signal (WDTOVF) in watchdog timer mode and an interrupt in interval timer mode. Use word access to write to WTCNT, writing H'5A in the upper byte. Use byte access to read from WTCNT. Note: The method for writing to WTCNT differs from that for other registers to prevent erroneous writes. See section 14.3.4, Notes on Register Access, for details.

The procedures for reading or writing to these registers are given below. (1) Writing to WTCNT and WTCSR These registers must be written by a word transfer instruction. They cannot be written by a byte or longword transfer instruction. When writing to WTCNT, set the upper byte to H'5A and transfer the lower byte as the write data, as shown in figure 14.2. When writing to WTCSR, set the upper byte to H'A5 and transfer the lower byte as the write data. This transfer procedure writes the lower byte data to WTCNT or WTCSR. WTCNT write 15 WTCSR write 8 15 Address: H'FFFE0000 0 7 H'5A Address: H'FFFE0002 Write data 8 7 H'A5 0 Write data Figure 14.2 Writing to WTCNT and WTCSR Page 712 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (2) Section 14 Watchdog Timer Writing to WRCSR WRCSR must be written by a word access to address H'FFFE0004. It cannot be written by byte transfer or longword transfer instructions. Procedures for writing 0 to WOVF (bit 7) and for writing to RSTE (bit 6) and RSTS (bit 5) are different, as shown in figure 14.3. To write 0 to the WOVF bit, the write data must be H'A5 in the upper byte and H'00 in the lower byte. This clears the WOVF bit to 0. The RSTE and RSTS bits are not affected. To write to the RSTE and RSTS bits, the upper byte must be H'5A and the lower byte must be the write data. The values of bits 6 and 5 of the lower byte are transferred to the RSTE and RSTS bits, respectively. The WOVF bit is not affected.

WTCSR is allocated to address H'FFFE0000, WTCNT to address H'FFFE0002, and WRCSR to address H'FFFE0004. Byte transfer instructions must be used for reading from these registers. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 713 of 3088 Section 14 Watchdog Timer 14.4 Usage 14.4.1 Canceling Software Standby Mode SH7268 Group, SH7269 Group This module can be used to cancel software standby mode with an interrupt such as an NMI interrupt. The procedure is described below. (This module does not operate when resets are used for canceling, so keep the RES or MRES pin low until clock oscillation settles.) 1. Before making a transition to software standby mode, always clear the TME bit in WTCSR to 0. When the TME bit is 1, an erroneous reset or interval timer interrupt may be generated when the count overflows. 2. Set the type of count clock used in the CKS[2:0] bits in WTCSR and the initial value of the counter in WTCNT. These values should ensure that the time till count overflow is longer than the clock oscillation settling time. 3. After setting the STBY and DEEP bits of the standby control register 1 (STBCR1: see section 49, Power-Down Modes) to 1 and 0 respectively, the execution of a SLEEP instruction puts the system in software standby mode and clock operation then stops. 4. This module starts counting by detecting the edge change of the NMI signal. 5. When the module count overflows, the clock pulse generator starts supplying the clock and this LSI resumes operation. The WOVF flag in WRCSR is not set when this happens. 14.4.2 Using Watchdog Timer Mode 1. Set the WT/IT bit in WTCSR to 1, the type of count clock in the CKS[2:0] bits in WTCSR, whether this LSI is to be reset internally or not in the RSTE bit in WRCSR, the reset type if it is generated in the RSTS bit in WRCSR, and the initial value of the counter in WTCNT. 2. Set the TME bit in WTCSR to 1 to start the count in watchdog timer mode. 3. While operating in watchdog timer mode, rewrite the counter periodically to H'00 to prevent the counter from overflowing. 4. When the counter overflows, this module sets the WOVF flag in WRCSR to 1, and the WDTOVF signal is output externally (figure 14.4). The WDTOVF signal can be used to reset the system. The WDTOVF signal is output for 64 x P0 clock cycles. 5. If the RSTE bit in WRCSR is set to 1, a signal to reset the inside of this LSI can be generated simultaneously with the WDTOVF signal. Either power-on reset or manual reset can be selected for this interrupt by the RSTS bit in WRCSR. The internal reset signal is output for 128 x P0 clock cycles. 6. When an overflow reset of this module is generated simultaneously with a reset input on the RES pin, the RES pin reset takes priority, and the WOVF bit in WRCSR is cleared to 0.

This enables interrupts to be generated at set periods. 1. Clear the WT/IT bit in WTCSR to 0, set the type of count clock in the CKS[2:0] bits in WTCSR, and set the initial value of the counter in WTCNT. 2. Set the TME bit in WTCSR to 1 to start the count in interval timer mode. 3. When the counter overflows, this module sets the IOVF bit in WTCSR to 1 and an interval timer interrupt request is sent to the interrupt controller. The counter then resumes counting.

The shortest such time period is thus one cycle of the peripheral clock, P0, while the longest is the result of frequency division according to the value in the CKS[2:0] bits. The timing of subsequent incrementation is in accord with the selected frequency division ratio. Accordingly, this time difference is referred to as timer variation. This also applies to the timing of the first incrementation after WTCNT has been written to during timer operation. 14.5.2 Prohibition against Setting H'FF to WTCNT When the value in WTCNT reaches H'FF, this module assumes that an overflow has occurred. Accordingly, when H'FF is set in WTCNT, an interval timer interrupt or reset will occur immediately, regardless of the current clock selection by the CKS[2:0] bits. 14.5.3 Interval Timer Overflow Flag When the value in WTCNT is H'FF, the IOVF flag in WTCSR cannot be cleared. Only clear the IOVF flag when the value in WTCNT has either become H'00 or been changed to a value other than H'FF.

Avoid input of the WDTOVF signal to the RES pin of this LSI through glue logic circuits. To reset the entire system with the WDTOVF signal, use the circuit shown in figure 14.6. Reset input (Low active) Reset signal to entire system (Low active) RES WDTOVF Figure 14.6 Example of System Reset Circuit Using WDTOVF Signal 14.5.5 Manual Reset in Watchdog Timer Mode When a manual reset occurs in watchdog timer mode, the bus cycle is continued. If a manual reset occurs while the bus is released or during burst transfer by the direct memory access controller, manual reset exception handling will be pended until the CPU acquires the bus mastership. 14.5.6 Internal Reset in Watchdog Timer Mode When an internal reset is generated by an overflow of the watchdog timer counter (WTCNT) in watchdog timer mode, the watchdog reset control/status register (WRCSR) is not initialized and the WOVF bit is set to 1. When the value of the WOVF bit is 1, no internal reset is generated when a WTCNT overflow occurs.

Clock running Disable alarm interrupt Write 0 to AIE in RCR1 to prevent errorneous interrupt Set alarm time Clear alarm flag Enable alarm interrupt Always reset, since the flag may have been set while the alarm time was being set. Write 1 to AIE in RCR1 Monitor alarm time (wait for interrupt or check alarm flag) Figure 15.4 Using Alarm Function Alarms can be generated using seconds, minutes, hours, day of the week, date, month, year, or any combination of these. Set the ENB bit in the register on which the alarm is placed to 1, and then set the alarm time in the lower bits. Clear the ENB bit in the register on which the alarm is not placed to 0. When the clock and alarm times match, 1 is set in the AF bit in RCR1. Alarm detection can be checked by reading this bit, but normally it is done by interrupt. If 1 is set in the AIE bit in RCR1, an interrupt is generated when an alarm occurs. The alarm flag is set when the clock and alarm times match. However, the alarm flag can be cleared by writing 0.

RSECCNT, RMINCNT, RHRCNT, RDAYCNT, RWKCNT, RMONCNT, RYRCONT The count must be stopped before writing to any of the above registers. 15.5.2 Use of Realtime Clock Periodic Interrupts The method of using the periodic interrupt function is shown in figure 15.5. A periodic interrupt can be generated periodically at the interval set by bits PES2 to PES0 in RCR2. When the time set by bits PES2 to PES0 has elapsed, the PEF is set to 1. The PEF is cleared to 0 upon periodic interrupt generation or when bits PES2 to PES0 are set. Periodic interrupt generation can be confirmed by reading this bit, but normally the interrupt function is used. Set PES, clear PEF Set PES2 to PES0 and clear PEF to 0 in RCR2 Elapse of time set by PES Clear PEF Clear PEF to 0 Figure 15.5 Using Periodic Interrupt Function 15.5.3 Transition to Standby Mode after Setting Register When a transition to standby mode is made after registers in this module are set, sometimes counting is not performed correctly. In case the registers are set, be sure to make a transition to standby mode after performing one dummy read of the register. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 749 of 3088 Section 15 Realtime Clock 15.5.4 SH7268 Group, SH7269 Group Usage Notes when Writing to and Reading the Register * When reading a counter register such as the seconds counter and the RCR2 register after having writing to the given register, dummy-read the register twice before reading the actual value. The register contents from before the write are returned by the two dummy reads, and the third read returns the register contents reflecting the write. * Registers other than the above can be read immediately after a write and the written value is reflected. Page 750 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 16 Serial Communication Interface with FIFO Section 16 Serial Communication Interface with FIFO This LSI has an eight-channel serial communication interface with FIFO that supports both asynchronous and clock synchronous serial communication. It also has 16-stage FIFO registers for both transmission and reception independently for each channel that enable this LSI to perform efficient high-speed continuous communication. 16.1 Features * Asynchronous serial communication: Serial data communication is performed by start-stop in character units. This module can communicate with a universal asynchronous receiver/transmitter (UART), an asynchronous communication interface adapter (ACIA), or any other communications chip that employs a standard asynchronous serial system. There are eight selectable serial data communication formats. Data length: 7 or 8 bits Stop bit length: 1 or 2 bits Parity: Even, odd, or none Receive error detection: Parity, framing, and overrun errors Break detection: Break is detected when a framing error is followed by at least one frame at the space 0 level (low level). It is also detected by reading the RxD level directly from the serial port register when a framing error occurs. * Clock synchronous serial communication: Serial data communication is synchronized with a clock signal. This module can communicate with other chips having a clock synchronous communication function. There is one serial data communication format. Data length: 8 bits Receive error detection: Overrun errors * Full duplex communication: The transmitting and receiving sections are independent, so this module can transmit and receive simultaneously. Both sections use 16-stage FIFO buffering, so high-speed continuous data transfer is possible in both the transmit and receive directions. * On-chip baud rate generator with selectable bit rates * Internal or external transmit/receive clock source: From either baud rate generator (internal) or SCK pin (external) R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 751 of 3088 Section 16 Serial Communication Interface with FIFO SH7268 Group, SH7269 Group * Four types of interrupts: Transmit-FIFO-data-empty interrupt, break interrupt, receive-FIFOdata-full interrupt, and receive-error interrupts are requested independently. * When this module is not in use, it can be stopped by halting the clock supplied to it, saving power. * In asynchronous mode, on-chip modem control functions (RTS and CTS) (only channel 1 on SH7268, only channels 1, 5, and 7 on SH7269). * The quantity of data in the transmit and receive FIFO data registers and the number of receive errors of the receive data in the receive FIFO data register can be ascertained. * A time-out error (DR) can be detected when receiving in asynchronous mode. * In asynchronous mode, the base clock frequency can be either 16 or 8 times the bit rate. * When an internal clock is selected as a clock source and the SCK pin is used as an input pin in asynchronous mode, either normal mode or double-speed mode can be selected for the baud rate generator.

Data input at the RxD pin is loaded into SCRSR in the order received, LSB (bit 0) first, converting the data to parallel form. When one byte has been received, it is automatically transferred to the receive FIFO data register (SCFRDR). The CPU cannot read or write to SCRSR directly. 16.3.2 Bit: 7 6 5 4 3 2 1 0 Initial value: R/W: - - - - - - - - Receive FIFO Data Register (SCFRDR) SCFRDR is a 16-byte FIFO register that stores serial receive data. The reception of one byte of serial data is complete when the received data is moved from the receive shift register (SCRSR) to SCFRDR for storage. Continuous reception is possible until 16 bytes are stored. The CPU can read but not write to SCFRDR. If data is read when there is no receive data in the SCFRDR, the value is undefined. When SCFRDR is full of receive data, subsequent serial data is lost.

Transmit data is loaded from the transmit FIFO data register (SCFTDR) into SCTSR, then the data is transmitted serially from the TxD pin, LSB (bit 0) first. After one data byte has been transmitted, the next transmit data is automatically loaded from SCFTDR into SCTSR and transmission is started again. The CPU cannot read from or write to SCTSR directly. 16.3.4 Bit: 7 6 5 4 3 2 1 0 Initial value: R/W: - - - - - - - - Transmit FIFO Data Register (SCFTDR) SCFTDR is a 16-byte FIFO register that stores data for serial transmission. When the transmit shift register (SCTSR) empty is detected, transmit data written in the SCFTDR is moved to SCTSR and serial transmission is started. Continuous serial transmission is performed until there is no transmit data left in SCFTDR. The CPU can write to SCFTDR at all times. When SCFTDR is full of transmit data (16 bytes), no more data can be written. If writing of new data is attempted, the data is ignored.

Receive data parity is checked according to the even/odd (O/E) mode setting. 4 O/E 0 R/W Parity Mode Selects even or odd parity when parity bits are added and checked. The O/E setting is used only in asynchronous mode and only when the parity enable bit (PE) is set to 1 to enable parity addition and checking. The O/E setting is ignored in clock synchronous mode, or in asynchronous mode when parity addition and checking is disabled. 1 0: Even parity* 2 1: Odd parity* Notes: 1. If even parity is selected, the parity bit is added to transmit data to make an even number of 1s in the transmitted character and parity bit combined. Receive data is checked to see if it has an even number of 1s in the received character and parity bit combined. 2. If odd parity is selected, the parity bit is added to transmit data to make an odd number of 1s in the transmitted character and parity bit combined. Receive data is checked to see if it has an odd number of 1s in the received character and parity bit combined.

If the second stop bit is 1, it is treated as a stop bit, but if the second stop bit is 0, it is treated as the start bit of the next incoming character. 0: One stop bit When transmitting, a single 1-bit is added at the end of each transmitted character. 1: Two stop bits When transmitting, two 1 bits are added at the end of each transmitted character. 2 0 R Reserved This bit is always read as 0.

The upper 8 bits indicate the number of receive errors in the receive FIFO data register, and the lower 8 bits indicate the status flag indicating operating state. The CPU can always read and write to SCFSR, but cannot write 1 to the status flags (ER, TEND, TDFE, BRK, RDF, and DR). These flags can be cleared to 0 only if they have first been read (after being set to 1). The PER flag (bits 15 to 12 and bit 2) and the FER flag (bits 11 to 8 and bit 3) are read-only bits that cannot be written.

Clearing the RE bit to 0 in SCSCR does not affect the ER bit, which retains its previous value. Even if a receive error occurs, the receive data is transferred to SCFRDR and the receive operation is continued. Whether or not the data read from SCFRDR includes a receive error can be detected by the FER and PER bits in SCFSR. 2. In two stop bits mode, only the first stop bit is checked; the second stop bit is not checked.

This module has a 16-stage FIFO buffer for both transmission and receptions, reducing the overhead of the CPU, and enabling continuous high-speed communication. Furthermore, channel 1 on the SH7268, and channels 1, 5, and 7 on the SH7269, have RTS and CTS signals for use as modem control signals. The transmission format is selected in the serial mode register (SCSMR), as shown in table 16.9. The clock source is selected by the combination of the CKE1 and CKE0 bits in the serial control register (SCSCR), as shown in table 16.10. (1) Asynchronous Mode * Data length is selectable: 7 or 8 bits * Parity bit is selectable. So is the stop bit length (1 or 2 bits). The combination of the preceding selections constitutes the communication format and character length. * In receiving, it is possible to detect framing errors, parity errors, receive FIFO data full, overrun errors, receive data ready, and breaks. * The number of stored data bytes is indicated for both the transmit and receive FIFO registers. * An internal or external clock can be selected as the clock source. When an internal clock is selected, this module operates using the clock of on-chip baud rate generator. When an external clock is selected, the external clock input must have a frequency 16 or 8 times the bit rate. (The on-chip baud rate generator is not used.) R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 791 of 3088 SH7268 Group, SH7269 Group Section 16 Serial Communication Interface with FIFO (2) Clock Synchronous Mode * The transmission/reception format has a fixed 8-bit data length. * In receiving, it is possible to detect overrun errors (ORER). * An internal or external clock can be selected as the clock source. When an internal clock is selected, this module operates using the clock of the on-chip baud rate generator, and outputs this clock to external devices as the synchronous clock. When an external clock is selected, this module operates on the input external synchronous clock not using the on-chip baud rate generator.

Serial communication is synchronized one character at a time. The transmitting and receiving sections in this module are independent, so full duplex communication is possible. The transmitter and receiver are 16-byte FIFO buffered, so data can be written and read while transmitting and receiving are in progress, enabling continuous transmitting and receiving. Figure 16.2 shows the general format of asynchronous serial communication. In asynchronous serial communication, the communication line is normally held in the mark (high) state. This module monitors the line and starts serial communication when the line goes to the space (low) state, indicating a start bit. One serial character consists of a start bit (low), data (LSB first), parity bit (high or low), and stop bit (high), in that order. When receiving in asynchronous mode, this module synchronizes at the falling edge of the start bit. This module samples each data bit on the eighth or fourth pulse of a clock with a frequency 16 or 8 times the bit rate. Receive data is latched at the center of each bit.

The format is selected by settings in the serial mode register (SCSMR).

The clock source is selected by the C/A bit in the serial mode register (SCSMR) and the CKE1 and CKE0 bits in the serial control register (SCSCR). For clock source selection, refer to table 16.10, SCSMR and SCSCR Settings and Clock Source Selection. When an external clock is input at the SCK pin, it must have a frequency equal to 16 or 8 times the desired bit rate. When this module operates on an internal clock, it can output a clock signal on the SCK pin. The frequency of this output clock is 16 or 8 times the desired bit rate. (3) Transmitting and Receiving Data * Initialization (Asynchronous Mode) Before transmitting or receiving, clear the TE and RE bits to 0 in the serial control register (SCSCR), then initialize this module as follows. When changing the operation mode or the communication format, always clear the TE and RE bits to 0 before following the procedure given below. Clearing TE to 0 initializes the transmit shift register (SCTSR). Clearing TE and RE to 0, however, does not initialize the serial status register (SCFSR), transmit FIFO data register (SCFTDR), or receive FIFO data register (SCFRDR), which retain their previous contents. Clear TE to 0 after all transmit data has been transmitted and the TEND flag in the SCFSR is set. The TE bit can be cleared to 0 during transmission, but the transmit data goes to the Mark state after the bit is cleared to 0. Set the TFRST bit in SCFCR to 1 and reset SCFTDR before TE is set again to start transmission. When an external clock is used, the clock should not be stopped during initialization or subsequent operation. The operation becomes unreliable if the clock is stopped. Page 796 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 16 Serial Communication Interface with FIFO Figure 16.3 shows a sample flowchart for initialization. Start of initialization Clear the TE and RE bits in SCSCR to 0 [1] Set the clock selection in SCSCR. Be sure to clear bits TIE, RIE, TE, and RE to 0. Set the TFRST and RFRST bits in SCFCR to 1 [2] Set the data transfer format in SCSMR. After reading flags ER, DR, and BRK in SCFSR, and each flag in SCLSR, write 0 to clear them Set the CKE1 and CKE0 bits in SCSCR (leaving bits TIE, RIE, TE, and RE cleared to 0) [1] Set data transfer format in SCSMR [2] Set the BGDM and ABCS bits in SCEMR Set value in SCBRR [3] Set the RTRG1, RTRG0, TTRG1, TTRG0, and MCE bits in SCFCR, and clear TFRST and RFRST bits to 0 Set the general I/O port external pins used SCK, TxD, RxD [4] Set the TE and RE bits in SCSCR to 1, and set the TIE, RIE, and REIE bits [5] End of initialization [3] Write a value corresponding to the bit rate into SCBRR. (Not necessary if an external clock is used.) [4] Sets the general I/O port external pins used. Set as RxD input at receiving and TxD at transmission. However, no setting for SCK pin is required when CKE[1:0] is 00. In the case when internal synchronous clock output is set, the SCK pin starts outputting the clock at this stage. [5] Set the TE bit or RE bit in SCSCR to 1. Also set the RIE, REIE, and TIE bits. Setting the TE and RE bits enables the TxD and RxD pins to be used. When transmitting, the SCIF will go to the mark state; when receiving, it will go to the idle state, waiting for a start bit.

Use the following procedure for serial data transmission after enabling transmission. Start of transmission [1] Status check and transmit data write: Read SCFSR and check that the TDFE flag is set to 1, then write transmit data to SCFTDR, and read 1 from the TDFE and TEND flags, then clear to 0. The quantity of transmit data that can be written is 16 - (transmit trigger set number). Read TDFE flag in SCFSR TDFE = 1? No Yes Write transmit data in SCFTDR, and read 1 from TDFE flag and TEND flag in SCFSR, then clear to 0 All data transmitted? [1] No [2] Yes [3] Break output during serial transmission: To output a break in serial transmission, clear the SPB2DT bit to 0 and set the SPB2IO bit to 1 in SCSPTR, then clear the TE bit in SCSCR to 0. Read TEND flag in SCFSR TEND = 1? [2] Serial transmission continuation procedure: To continue serial transmission, read 1 from the TDFE flag to confirm that writing is possible, then write data to SCFTDR, and then clear the TDFE flag to 0. No Yes Break output? No Yes Clear SPB2DT to 0 and set SPB2IO to 1 [3] In [1] and [2], it is possible to ascertain the number of data bytes that can be written from the number of transmit data bytes in SCFTDR indicated by the upper 8 bits of SCFDR. Clear TE bit in SCSCR to 0 End of transmission Figure 16.4 Sample Flowchart for Transmitting Serial Data Page 798 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 16 Serial Communication Interface with FIFO In serial transmission, this module operates as described below. 1. When data is written into the transmit FIFO data register (SCFTDR), the data is transferred from SCFTDR to the transmit shift register (SCTSR). Confirm that the TDFE flag in the serial status register (SCFSR) is set to 1 before writing transmit data to SCFTDR. The number of data bytes that can be written is (16 - transmit trigger setting). 2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive transmit operations are performed until there is no transmit data left in SCFTDR. When the number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register (SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is generated. The serial transmit data is sent from the TxD pin in the following order. A. Start bit: One-bit 0 is output. B. Transmit data: 8-bit or 7-bit data is output in LSB-first order. C. Parity bit: One parity bit (even or odd parity) is output. (A format in which a parity bit is not output can also be selected.) D. Stop bit(s): One or two 1 bits (stop bits) are output. E. Mark state: 1 is output continuously until the start bit that starts the next transmission is sent. 3. The SCFTDR transmit data is checked at the timing for sending the stop bit. If data is present, the data is transferred from SCFTDR to SCTSR, the stop bit is sent, and then serial transmission of the next frame is started.

When modem control is enabled on channel 1 on the SH7268, or on channel 1, 5, or 7 on the SH7269, transmission can be stopped and restarted in accordance with the CTS input value. When CTS is set to 1, if transmission is in progress, the line goes to the mark state after transmission of one frame. When CTS is set to 0, the next transmit data is output starting from the start bit. Figure 16.6 shows an example of the operation when modem control is used.

Use the following procedure for serial data reception after enabling reception. [1] Receive error handling and break detection: Start of reception Read ER, DR, BRK flags in SCFSR and ORER flag in SCLSR ER, DR, BRK or ORER = 1? No Read RDF flag in SCFSR No [1] Yes Error handling [2] Yes Read receive data in SCFRDR, and clear RDF flag in SCFSR to 0 All data received? Yes Clear RE bit in SCSCR to 0 End of reception [2] Status check and receive data read: Read SCFSR and check that RDF flag = 1, then read the receive data in SCFRDR, read 1 from the RDF flag, and then clear the RDF flag to 0. The transition of the RDF flag from 0 to 1 can also be identified by a receive FIFO data full interrupt (RXI). RDF = 1? No Read the DR, ER, and BRK flags in SCFSR, and the ORER flag in SCLSR, to identify any error, perform the appropriate error handling, then clear the DR, ER, BRK, and ORER flags to 0. In the case of a framing error, a break can also be detected by reading the value of the RxD pin. [3] [3] Serial reception continuation procedure: To continue serial reception, read at least the receive trigger set number of receive data bytes from SCFRDR, read 1 from the RDF flag, then clear the RDF flag to 0. The number of receive data bytes in SCFRDR can be ascertained by reading from SCRFDR.

The transmission line is monitored, and if a 0 start bit is detected, internal synchronization is performed and reception is started. 2. The received data is stored in SCRSR in LSB-to-MSB order. 3. The parity bit and stop bit are received. After receiving these bits, this module carries out the following checks. A. Stop bit check: Checks whether the stop bit is 1. If there are two stop bits, only the first is checked. B. Checks whether receive data can be transferred from the receive shift register (SCRSR) to SCFRDR. C. Overrun check: Checks that the ORER flag is 0, indicating that the overrun error has not occurred. D. Break check: Checks that the BRK flag is 0, indicating that the break state is not set. If all the above checks are passed, the receive data is stored in SCFRDR. Note: When a parity error or a framing error occurs, reception is not suspended. 4. If the RIE bit in SCSCR is set to 1 when the RDF or DR flag changes to 1, a receive-FIFOdata-full interrupt (RXI) request is generated. If the RIE bit or the REIE bit in SCSCR is set to 1 when the ER flag changes to 1, a receive-error interrupt (ERI) request is generated. If the RIE bit or the REIE bit in SCSCR is set to 1 when the BRK or ORER flag changes to 1, a break reception interrupt (BRI) request is generated.

This mode is suitable for high-speed serial communication. The transmitter and receiver in this module are independent, so full-duplex communication is possible while sharing the same clock. The transmitter and receiver are also 16-byte FIFO buffered, so continuous transmitting or receiving is possible by reading or writing data while transmitting or receiving is in progress. Figure 16.11 shows the general format in clock synchronous serial communication.

Data is guaranteed valid at the rising edge of the serial clock. In each character, the serial data bits are transmitted in order from the LSB (first) to the MSB (last). After output of the MSB, the communication line remains in the state of the MSB. In clock synchronous mode, data is received in synchronization with the rising edge of the serial clock.

No parity bit can be added. (2) Clock An internal clock generated by the on-chip baud rate generator by the setting of the C/A bit in SCSMR and CKE[1:0] in SCSCR, or an external clock input from the SCK pin can be selected as the transmit/receive clock. When this module operates on an internal clock, it outputs the clock signal at the SCK pin. Eight clock pulses are output per transmitted or received character. When transmission or reception is not performed, the clock signal remains in the high state. When only receiving, the clock signal outputs while the RE bit of SCSCR is 1 and the number of data in receive FIFO is more than the receive FIFO data trigger number. (3) Transmitting and Receiving Data * Initialization (Clock Synchronous Mode) Before transmitting, receiving, or changing the mode or communication format, the software must clear the TE and RE bits to 0 in the serial control register (SCSCR), then initialize this module. Clearing TE to 0 initializes the transmit shift register (SCTSR). Clearing RE to 0, however, does not initialize the RDF, PER, FER, and ORER flags and receive data register (SCRDR), which retain their previous contents.

Also set the TIE, RIE, and REIE bits to enable the TxD, RxD, and SCK pins to be used. When transmitting, the TxD pin will go to the mark state. When receiving in clocked synchronous mode with the synchronization clock output (clock master) selected, a clock starts to be output from the SCK pin at this point.

Use the following procedure for serial data transmission after enabling transmit operation. Start of transmission [1] Status check and transmit data write: Read SCFSR and check that the TDFE flag is set to 1, then write transmit data to SCFTDR.

When data is written into the transmit FIFO data register (SCFTDR), the data is transferred from SCFTDR to the transmit shift register (SCTSR). Confirm that the TDFE flag in the serial status register (SCFSR) is set to 1 before writing transmit data to SCFTDR. The number of data bytes that can be written is (16 - transmit trigger setting). 2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive transmit operations are performed until there is no transmit data left in SCFTDR. When the number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register (SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is generated. If clock output mode is selected, eight synchronous clock pulses are output. If an external clock source is selected, data is output in synchronization with the input clock. Data is output from the TxD pin in order from the LSB (bit 0) to the MSB (bit 7). 3. The SCFTDR transmit data is checked at the timing for sending the MSB (bit 7). If data is present, the data is transferred from SCFTDR to SCTSR, and then serial transmission of the next frame is started. If there is no data, the TxD pin holds the state after the TEND flag in SCFSR is set to 1 and the MSB (bit 7) is sent. 4. After the end of serial transmission, the SCK pin is held in the high state. Figure 16.14 shows an example of transmit operation.

Use the following procedure for serial data reception after enabling receive operation. When switching from asynchronous mode to clock synchronous mode without initialization, make sure that ORER, PER, and FER are cleared to 0. Start of reception [1] Receive error handling: Read the ORER flag in SCLSR to identify any error, perform the appropriate error handling, then clear the ORER flag to 0.

[2] Status check and receive data read: Read SCFSR and check that RDF = 1, then read the receive data in SCFRDR, and clear the RDF flag to 0.

Yes Clear RE bit in SCSCR to 0 End of reception [3] [3] Serial reception continuation procedure: To continue serial reception, read at least the receive trigger set number of receive data bytes from SCFRDR, read 1 from the RDF flag, then clear the RDF flag to 0. The number of receive data bytes in SCFRDR can be ascertained by reading SCFRDR. However, the RDF bit is cleared to 0 automatically when an RXI interrupt activates the direct memory access controller to read the data in Figure 16.15 Sample Flowchart for Receiving Serial Data (1) Page 810 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 16 Serial Communication Interface with FIFO Error handling No ORER = 1? Yes Overrun error handling Clear ORER flag in SCLSR to 0 End Figure 16.16 Sample Flowchart for Receiving Serial Data (2) In serial reception, this module operates as described below. 1. Reception is started in synchronization with serial clock input or output. 2. Receive data is shifted into SCRSR in order from the LSB to the MSB. After the data reception, whether the receive data can be loaded from SCRSR into SCFRDR or not is checked. If this check is passed, the RDF flag is set to 1 and the received data is stored in SCFRDR. If the check is not passed (overrun error is detected), further reception is prevented. 3. After setting RDF to 1, if the receive FIFO data full interrupt enable bit (RIE) is set to 1 in SCSCR, a receive-data-full interrupt (RXI) request is generated. If the ORER bit is set to 1 and the receive-data-full interrupt enable bit (RIE) or the receive error interrupt enable bit (REIE) in SCSCR is also set to 1, a break interrupt (BRI) request is generated.

Use the following procedure for the simultaneous transmission/reception of serial data, after enabling transmit/receive operation.

Similarly, read 1 from the TDFE flag to confirm that writing is possible before transmitting the MSB in the current frame. Then write data to SCFTDR and clear the TDFE flag to 0. All data received? Yes Clear TE and RE bits in SCSCR to 0 [4] Note: When switching from a transmit operation or receive operation to simultaneous transmission and reception operations, clear the TE and RE bits to 0, and then set them simultaneously to 1. End of transmission and reception Figure 16.18 Sample Flowchart for Transmitting/Receiving Serial Data R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 813 of 3088 SH7268 Group, SH7269 Group Section 16 Serial Communication Interface with FIFO 16.5 Interrupts This module has four interrupt sources: transmit-FIFO-data-empty (TXI), receive-error (ERI), receive FIFO data full (RXI), and break (BRI). Table 16.12 shows the interrupt sources and their order of priority. The interrupt sources are enabled or disabled by means of the TIE, RIE, and REIE bits in SCSCR. A separate interrupt request is sent to the interrupt controller for each of these interrupt sources. When a TXI request is enabled by the TIE bit and the TDFE flag in the serial status register (SCFSR) is set to 1, a TXI interrupt request is generated. The direct memory access controller can be activated and data transfer performed by this TXI interrupt request. At this time, an interrupt request is not sent to the CPU. When an RXI request is enabled by the RIE bit and the RDF flag or the DR flag in SCFSR is set to 1, an RXI interrupt request is generated. The direct memory access controller can be activated and data transfer performed by this RXI interrupt request. At this time, an interrupt request is not sent to the CPU. The RXI interrupt request caused by the DR flag is generated only in asynchronous mode. When the RIE bit is set to 0 and the REIE bit is set to 1, this module requests only an ERI or a BRI interrupt without requesting an RXI interrupt. The TXI indicates that transmit data can be written, and the RXI indicates that there is receive data in SCFRDR. Table 16.12 Interrupt Sources Interrupt Source Description Direct Memory Access Controller Priority on Activation Reset Release BRI Interrupt initiated by break (BRK) or overrun error (ORER) Not possible ERI Interrupt initiated by receive error (ER) Not possible RXI Interrupt initiated by receive FIFO data full (RDF) or Possible data ready (DR) TXI Interrupt initiated by transmit FIFO data empty (TDFE) Page 814 of 3088 High Possible Low R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 16.6 Section 16 Serial Communication Interface with FIFO Usage Notes Note the following when using this module. 16.6.1 SCFTDR Writing and TDFE Flag The TDFE flag in the serial status register (SCFSR) is set when the number of transmit data bytes written in the transmit FIFO data register (SCFTDR) has fallen below the transmit trigger number set by bits TTRG[1:0] in the FIFO control register (SCFCR). After the TDFE flag is set, transmit data up to the number of empty bytes in SCFTDR can be written, allowing efficient continuous transmission. However, if the number of data bytes written in SCFTDR is equal to or less than the transmit trigger number, the TDFE flag will be set to 1 again after being read as 1 and cleared to 0. TDFE flag clearing should therefore be carried out when SCFTDR contains more than the transmit trigger number of transmit data bytes. The number of transmit data bytes in SCFTDR can be found from the upper 8 bits of the FIFO data count register (SCFDR). 16.6.2 SCFRDR Reading and RDF Flag The RDF flag in the serial status register (SCFSR) is set when the number of receive data bytes in the receive FIFO data register (SCFRDR) has become equal to or greater than the receive trigger number set by bits RTRG[1:0] in the FIFO control register (SCFCR). After RDF flag is set, receive data equivalent to the trigger number can be read from SCFRDR, allowing efficient continuous reception. However, if the number of data bytes in SCFRDR exceeds the trigger number, the RDF flag will be set to 1 again if it is cleared to 0. The RDF flag should therefore be cleared to 0 after being read as 1 after reading the number of the received data in the receive FIFO data register (SCFRDR) which is less than the trigger number. The number of receive data bytes in SCFRDR can be found from the lower 8 bits of the FIFO data count register (SCFDR). R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 815 of 3088 Section 16 Serial Communication Interface with FIFO 16.6.3 SH7268 Group, SH7269 Group Restriction on Direct Memory Controller Usage When the direct memory access controller writes data to SCFTDR due to a TXI interrupt request, the state of the TEND flag becomes undefined. Therefore, the TEND flag should not be used as the transfer end flag in such a case. 16.6.4 Break Detection and Processing Break signals can be detected by reading the RxD pin directly when a framing error (FER) is detected. In the break state the input from the RxD pin consists of all 0s, so the FER flag is set and the parity error flag (PER) may also be set. Note that, although transfer of receive data to SCFRDR is halted in the break state, the receive operation is continued. 16.6.5 Sending a Break Signal The I/O condition and level of the TxD pin are determined by the SPB2IO and SPB2DT bits in the serial port register (SCSPTR). This feature can be used to send a break signal. Until TE bit is set to 1 (enabling transmission) after initializing, the TxD pin does not work. During the period, mark status is performed by the SPB2DT bit. Therefore, the SPB2IO and SPB2DT bits should be set to 1 (high level output). To send a break signal during serial transmission, clear the SPB2DT bit to 0 (designating low level), then clear the TE bit to 0 (halting transmission). When the TE bit is cleared to 0, the transmitter is initialized regardless of the current transmission state, and 0 is output from the TxD pin. 16.6.6 Receive Data Sampling Timing and Receive Margin (Asynchronous Mode) This module operates on a base clock with a frequency 16 or 8 times the bit rate. In reception, the falling edge of the start bit is sampled at the base clock to perform synchronization internally. Receive data is latched at the rising edge of the eighth or fourth base clock pulse. When this module operates on a base clock with a frequency 16 times the bit rate, the receive data is sampled at the timing shown in figure 16.19.

Equation 1: M = (0.5 - D - 0.5 1 ) - (L - 0.5) F - (1 + F) x 100 % 2N N Where: M: Receive margin (%) N: Ratio of clock frequency to bit rate (N = 16 or 8) D: Clock duty (D = 0 to 1.0) L: Frame length (L = 9 to 12) F: Absolute deviation of clock frequency From equation 1, if F = 0, D = 0.5 and N = 16, the receive margin is 46.875%, as given by equation 2. Equation 2: When D = 0.5 and F = 0: M = (0.5 - 1/(2 x 16)) x 100% = 46.875% This is a theoretical value. A reasonable margin to allow in system designs is 20% to 30%. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 817 of 3088 Section 16 Serial Communication Interface with FIFO 16.6.7 SH7268 Group, SH7269 Group Selection of Base Clock in Asynchronous Mode In this LSI, when asynchronous mode is selected, the base clock frequency within a bit period can be set to the frequency 16 or 8 times the bit rate by setting the ABCS bit in SCEMR. Note that, however, if the base clock frequency 8 times the bit rate is used, receive margin is decreased as calculated using equation 1 in section 16.6.6, Receive Data Sampling Timing and Receive Margin (Asynchronous Mode). If the desired bit rate can be set simply by setting SCBRR and the CKS1and CKS0 bits in SCSMR, it is recommended to use the base clock frequency within a bit period 16 times the bit rate (by setting the ABCS bit in SCEMR to 0). If an internal clock is selected as a clock source and the SCK pin is not used, the bit rate can be increased without decreasing receive margin by selecting double-speed mode for the baud rate generator (setting the BGDM bit in SCEMR to 1).

The transmit buffer (SPTX) and receive buffer (SPRX) are independent and are mapped to SPDR. SPDR should be read or written to in byte, word, or longword units according to the access width specification bit (SPLW) in the data control register (SPDCR). The bit length to be used is determined by the data length specification bits (SPB3 to SPB0) in the command register (SPCMD). When data is written to SPDR, the data will be written to the transmit buffer from SPDR if the transmit buffer has a space equal to or more than the SPDR access width. If there is not enough space, data will not be written to the transmit buffer. Even if an attempt is made to write data to the buffer, the data is ignored. When data is read from SPDR, receive data in the receive buffer will be read. If SPDR is read when there is no receive data in the receive buffer, the read value is undefined. When SPDR is written to with the longword-, word-, or byte-access width, the transmit data should be written to the following bits. If data is written to the other bits, the data is not guaranteed. * Longword: Bits 31 to 0 * Word: Bits 31 to 16 * Byte: Bits 31 to 24 When SPDR is read with the longword-, word-, or byte-access width, the receive data should be read from the following bits. If data is read from the other bits, the data is not guaranteed. * Longword: Bits 31 to 0 * Word: Bits 31 to 16 * Byte: Bits 31 to 24 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 833 of 3088 SH7268 Group, SH7269 Group Section 17 Renesas Serial Peripheral Interface Bit: 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 SPD31 SPD30 SPD29 SPD28 SPD27 SPD26 SPD25 SPD24 SPD23 SPD22 SPD21 SPD20 SPD19 SPD18 SPD17 SPD16 Initial value: Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined R/W: R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W Bit: 15 14 13 12 11 10 9 SPD15 SPD14 SPD13 SPD12 SPD11 SPD10 SPD9 8 7 6 5 4 3 2 1 0 SPD8 SPD7 SPD6 SPD5 SPD4 SPD3 SPD2 SPD1 SPD0 Initial value: Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined Undefined R/W: R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W 17.3.6 Sequence Control Register (SPSCR) SPSCR sets the sequence controlled method when this module operates in master mode.

SPCMD0 to SPCMD3 are used to set a transfer format for master mode operation. Some of the bits in SPCMD0 are used to set a transfer mode for slave mode operation. In master mode, this module sequentially references SPCMD0 to SPCMD3 according to the settings in bits SPSLN1 and SPSLN0 in the sequence control register (SPSCR), and executes the serial transfer that is set in the referenced SPCMD. While bit TEND in the status register (SPSR) indicates that transmission is not completed, correct operation of this module cannot be guaranteed if SPCMD is changed that is referred by this module. SPCMD referenced by this module in master mode can be checked by means of bits SPCP1 and SPCP0 in the sequence status register (SPSSR). When the function of this module in slave mode is enabled, operation cannot be guaranteed if the value set in SPCMD0 is changed.

A bit rate is determined by combinations of bits BRDV1 and BRDV 0 and the settings in the bit rate register (SPBR) (see section 17.3.8, Bit Rate Register (SPBR)). The settings in SPBR determine the base bit rate. The settings in bits BRDV1 and BRDV0 are used to select a bit rate which is obtained by dividing the base bit rate by 1, 2, 4, or 8. In the bits SPCMD0 to SPCMD3, different BRDV1 and BRDV0 settings can be specified. This permits the execution of serial transfers at a different bit rate for each command. 00: Select the base bit rate 01: Select the base bit rate divided by 2 10: Select the base bit rate divided by 4 11: Select the base bit rate divided by 8 Page 846 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 17 Renesas Serial Peripheral Interface Bit Bit Name Initial Value R/W Description 1 CPOL 0 R/W RSPCK Polarity Setting Sets an RSPCK polarity in master or slave mode.

In master/slave configuration, the SSL output of this LSI (master) is not used. The SSL input of the slave is fixed to the low level, and the slave is always maintained in a selected state. In the transfer format corresponding to the case where the CPHA bit in the control register (SPCR) is 0, there are slave devices for which the SSL signal cannot be fixed to the active level. In situations where the SSL signal cannot be fixed, the SSL output of this LSI should be connected to the SSL input of the slave device. This LSI (master) always drives the RSPCK and MOSI. The slave always drives the MISO.

In the slave configuration in which the CPHA bit in the command register (SPCMD) is set to 1, the SSL input of this LSI (slave) is fixed to the 0 level, this LSI (slave) is always maintained in a selected state, and in this manner it is possible to execute serial transfer (figure 17.4).

In the example of figure 17.5, the system is comprised of an master and two LSIs (slave X and slave Y). The RSPCK and MOSI outputs of the master are connected to the RSPCK and MOSI inputs of the LSIs (slave X and slave Y). The MISO outputs of the LSIs (slave X and slave Y) are all connected to the MISO input of the master. SSLX and SSLY outputs of the master are connected to the SSL inputs of the LSIs (slave X and slave Y), respectively. The master always drives RSPCK, MOSI, SSLX, and SSLY.

In figure 17.6, RSPCK (CPOL = 0) indicates the RSPCK signal waveform when the CPOL bit in SPCMD is 0; RSPCK (CPOL = 1) indicates the RSPCK signal waveform when the CPOL bit is 1. The sampling timing represents the timing at which this module fetches serial transfer data into the shift register. The input/output directions of the signals depend on the settings of this module. For details, see section 17.4.2, Pin Control. When the CPHA bit is 0, the driving of valid data to the MOSI and MISO signals commences at an SSL signal assertion timing. The first RSPCK signal change timing that occurs after the SSL signal assertion becomes the first transfer data fetching timing. After this timing, data is sampled at every 1 RSPCK cycle. The change timing for MOSI and MISO signals is always 1/2 RSPCK cycle after the transfer data fetch timing. The settings in the CPOL bit do not affect the RSPCK signal operation timing; they only affect the signal polarity. t1 denotes a period from an SSL signal assertion to RSPCK oscillation (RSPCK delay). t2 denotes a period from the cessation of RSPCK oscillation to an SSL signal negation (SSL negation delay). t3 denotes a period in which SSL signal assertion is suppressed for the next transfer after the end of serial transfer (next-access delay). t1, t2, and t3 are controlled by a master device running on the system. For a description of t1, t2, and t3 when this module is in master mode, see section 17.4.3 (1), Master/Slave (with This LSI Acting as Master).

In figure 17.7, RSPCK (CPOL = 0) indicates the RSPCK signal waveform when the CPOL bit in SPCMD is 0; RSPCK (CPOL = 1) indicates the RSPCK signal waveform when the CPOL bit is 1. The sampling timing represents the timing at which this module fetches serial transfer data into the shift register. The input/output directions of the signals depend on the modes (master or slave). For details, see section 17.4.2, Pin Control. When the CPHA bit is 1, the driving of invalid data to the MOSI and MISO signals commences at an SSL signal assertion timing. The driving of valid data to the MOSI and MISO signals commences at the first RSPCK signal change timing that occurs after the SSL signal assertion. After this timing, data is updated at every 1 RSPCK cycle. The transfer data fetch timing is always 1/2 RSPCK cycle after the data update timing. The settings in the CPOL bit do not affect the RSPCK signal operation timing; they only affect the signal polarity. t1, t2, and t3 are the same as those in the case of CPHA = 0.

Irrespective of MSB/LSB first, this module treats the range from the LSB of the data register (SPDR) to the assigned data length as transfer data. (1) MSB First Transfer (32-Bit Data) Figure 17.8 shows the operation of the transmit buffer (SPTX) and the shift register when this module performs a 32-bit data length MSB-first data transfer. The CPU or direct memory access controller writes T31 to T00 to the transmit buffer of SPDR. If the shift register is empty, this module copies the data in the transmit buffer to the shift register, and fully populates the shift register. When serial transfer starts, this module outputs data from the MSB (bit 31) of the shift register, and shifts in the data from the LSB (bit 0) of the shift register. When the RSPCK cycle required for the serial transfer of 32 bits has passed, data R31 to R00 is stored in the shift register. In this state, this module copies the data from the shift register to the receive buffer, and empties the shift register. If the receive buffer does not have a space for the receive data length after the receive data has been copied from the shift register to the receive buffer, another serial transfer will not be started. In order to start another serial transfer, data for the receive data length should be read from the receive buffer to secure the necessary space in the receive buffer. If another serial transfer is started before the CPU or direct memory access controller writes to the transmit buffer, received data R31 to R00 is shifted out from the shift register.

The CPU or direct memory access controller writes T15 to T00 to the transmit buffer. If the shift register is empty, this module copies the data in the transmit buffer to the shift register, and fully populates the shift register. When serial transfer starts, this module outputs data from bit 15 of the shift register, and shifts in the data from the LSB (bit 0) of the shift register. When the RSPCK cycle required for the serial transfer of 16 bits has passed, received data R15 to R00 is stored in bits 15 to 0 of the shift register. After completion of the serial transfer, data that existed before the transfer is retained in bits 31 to 16 in the shift register. In this state, this module copies the data from the shift register to the receive buffer, and empties the shift register. If the receive buffer does not have a space for the receive data length after receive data has been copied from the shift register to the receive buffer, another serial transfer will not be started. In order to start another serial transfer, data for the receive data length should be read from the receive buffer to secure the necessary space in the receive buffer. If another serial transfer is started before the CPU or direct memory access controller writes to the transmit buffer, received data R15 to R00 is shifted out from the shift register.

If access is made to SPDR, depending on the status of the transmit buffer/receive buffer or the status at the beginning or end of serial transfer, in some cases non-normal transfers can be executed. If a non-normal transfer operation occurs, this module detects the event as an overrun error or a mode fault error. Table 17.7 shows the relationship between non-normal transfer operations and the error detection function.

Whether SPDR can be written to or not can be checked using the T[3:0] bits in the buffer data count setting register (SPBFDR). Likewise, this module does not detect an error on operation B. In a serial transfer that was started before the shift register was updated, this module sends the data that was received in the previous serial transfer, and does not treat the operation indicated in B as an error. Note that the received data from the previous serial transfer is retained in the receive buffer of SPDR, thus it can be correctly read. Similarly, this module does not detect an error on operation C. To prevent extraneous data from being read, the number of receive data units stored in the receive buffer should be read from the R[5:0] bits in the buffer data count setting register (SPBFDR). An overrun error shown in D is described in section 17.4.6 (1), Overrun Error. A mode fault error shown in E is described in section 17.4.6 (2), Mode Fault Error.

When the OVRF bit is 1, this module does not copy data from the shift register to the receive buffer so that the data prior to the occurrence of the error is retained in the receive buffer. To reset the OVRF bit in SPSR to 0, either perform a power-on reset, or write a 0 to the OVRF bit after SPSR has been read with the OVRF bit set to 1. Figure 17.14 shows an example of operation of the SPRF and OVRF bits in SPSR. The SPSR and SPDR accesses shown in figure 17.14 indicates the condition of accesses to SPSR and SPDR, respectively, where I denotes an idle cycle, W a write cycle, and R a read cycle. In the example of figure 17.14, this module performs an 8-bit serial transfer in which the CPHA bit in the command register (SPCMD) is 1, and CPOL is 0.

If a serial transfer terminates when the receive buffer does not have a space for the receive data length, this module detects an overrun error, and sets the OVRF bit to 1. This module does not copy the data in the shift register to the receive buffer. 2. The OVFR bit is not cleared even when SPDR is read and thus the number of data bytes in the receive buffer becomes less than the number of the receive buffer data triggering number specified by the RXTRG bits. 3. If the serial transfer terminates in an overrun error state, this module determines that the shift register is empty; in this manner, data transfer is enabled from the transmit buffer to the shift register. 4. If 0 is written to the OVRF bit after SPSR is read with OVRF = 1, this module clears the OVRF bit. The occurrence of an overrun can be checked either by reading SPSR or by using an error interrupt and reading SPSR. When using an error interrupt, set the SPEIE bit in the control register (SPCR) to 1. When executing a serial transfer without using an error interrupt, measures should be taken to ensure the early detection of overrun errors, such as reading SPSR immediately after SPDR is read. The OVRF bit is cleared to 0 under the following conditions: * After SPSR is read in a condition in which the OVRF bit is set to 1, 0 is written to the OVRF bit. * Power-on reset Note: When the receive buffer has area enough to store receive data with an overrun error, this module receives receive data.

This module detects a mode fault error if the SSL input signal is negated during the serial transfer period (from the time the driving of valid data is started to the time the final valid data is fetched) when the MODFEN bit is 1 in slave mode. Upon detecting a mode fault error, this module stops driving of the output signals and clears the SPE bit in SPCR to 0. When the SPE bit is cleared to 0, the function of this module is disabled and this module stops driving external signals. For details of disabling the function of this module by clearing the SPE bit to 0, see section 17.4.7, Initialization. The occurrence of a mode fault error can be checked either by reading SPSR or by using an error interrupt and reading SPSR. When using an error interrupt, set the SPEIE bit in the control register (SPCR) to 1. To detect a mode fault error without using an error interrupt, it is necessary to poll SPSR. When the MODF bit is 1, writing 1 to the SPE bit is ignored. To enable the function of this module after the detection of a mode fault error, the MODF bit must be set to 0. The MODF bit is cleared to 0 under the following conditions: * After SPSR is read in a condition where the MODF bit has turned 1, 0 is written to the MODF bit. * Power-on reset Page 874 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 17.4.7 Section 17 Renesas Serial Peripheral Interface Initialization If 0 is written to the SPE bit in the control register (SPCR) or this module clears the SPE bit to 0 because of the detection of a mode fault error, this module disables the module function, and initializes a part of the module function. When a power-on reset is generated, this module initializes all of the module function. An explanation of initialization by the clearing of the SPE bit follows. (1) Initialization by Clearing SPE Bit When the SPE bit in SPCR is cleared, this module performs the following initialization: * Suspending any serial transfer that is being executed * Stopping the driving of output signals (Hi-Z) in slave mode * Initializing the internal state * Initializing the TEND bit in SPSR Initialization by the clearing of the SPE bit does not initialize the control bits of this module. For this reason, this module can be started in the same transfer mode as prior to the initialization if the SPE bit is re-set to 1. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 875 of 3088 Section 17 Renesas Serial Peripheral Interface 17.4.8 (1) SH7268 Group, SH7269 Group SPI Operation Multi-Master Mode Operation This section explains the operation in multi-master mode. (a) Starting Serial Transfer A serial transfer is started when transmit data is copied from the transmit buffer to the shift register, the shift register becomes full, and the receive buffer has a space for the receive data length. If transmit data has already been written to the shift register, data is not copied from the transmit buffer to the shift register. For details of the transfer format, see section 17.4.4, Transfer Format. (b) Terminating Serial Transfer Irrespective of the CPHA bit in the command register (SPCMD), this module terminates the serial transfer after transmitting an RSPCK edge corresponding to the final sampling timing. After the serial transfer is completed, receive data is copied from the shift register to the receive buffer. If the receive buffer does not have a space for the receive data length after receive data is copied from the shift register to the receive buffer, another serial transfer will not be performed. In order to perform another serial transfer, data for the receive data length should be read from the receive buffer to secure the space for the receive data. It should be noted that the final sampling timing varies depending on the bit length of transfer data. In master mode, the data length depends on the settings in bits SPB3 to SPB0 in SPCMD. For details on the transfer format, see section 17.4.4, Transfer Format. Page 876 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (c) Section 17 Renesas Serial Peripheral Interface Sequence Control The transfer format that is employed in master mode is determined by the sequence control register (SPSCR), command registers 0 to 3 (SPCMD0 to SPCMD3), the bit rate register (SPBR), the clock delay register (SPCKD), the slave select negation delay register (SSLND), and the nextaccess delay register (SPND). SPSCR is a register used to determine the sequence configuration for serial transfers that are executed by this module in master mode. The following items are set in command registers SPCMD0 to SPCMD3: SSL output signal value, MSB/LSB first, data length, some of the bit rate settings, RSPCK polarity/phase, whether SPCKD is to be referenced, whether SSLND is to be referenced, and whether SPND is to be referenced. SPBR holds some of the bit rate settings; SPCKD, a clock delay value; SSLND, an SSL negation delay; and SPND, a next-access delay value. According to the sequence length that is assigned to SPSCR, this module makes up a sequence comprised of a part or all of SPCMD0 to SPCMD3. This module contains a pointer to the SPCMD that makes up the sequence. The value of this pointer can be checked by reading bits SPCP1 and SPCP0 in the sequence status register (SPSSR). When the SPE bit in the control register (SPCR) is set to 1 and the function of this module is enabled, this module loads the pointer to the commands in SPCMD0, and incorporates the SPCMD0 settings into the transfer format at the beginning of serial transfer. This module increments the pointer each time the next-access delay period for a data transfer ends. Upon completion of the serial transfer that corresponds to the final command comprising the sequence, this module sets the pointer in SPCMD0, and in this manner the sequence is executed repeatedly.

If the SSL signal level for the next serial transfer is the same as the SSL signal level for the current serial transfer, this module can execute continuous serial transfers while keeping the SSL signal assertion status (burst transfer). Figure 17.16 shows an example of an SSL signal operation for the case where a burst transfer is implemented using SPCMD0 and SPCMD1 settings. The text below explains operations (1) to (7) as depicted in figure 17.16. It should be noted that the polarity of the SSL output signal depends on the settings in the slave select polarity register (SSLP). 1. Based on SPCMD0, this module asserts the SSL signal and inserts RSPCK delays. 2. Serial transfers are executed according to SPCMD0. 3. SSL negation delays are inserted. 4. Because the SSLKP bit in SPCMD0 is 1, this module keeps the SSL signal value on SPCMD0. This period is sustained, at the shortest, for a period equal to the next-access delay of SPCMD0. If the shift register is empty after the passage of a minimum period, this period is sustained until such time as the transmit data is stored in the shift register for another transfer. 5. Based on SPCMD1, this module asserts the SSL signal and inserts RSPCK delays. 6. Serial transfers are executed according to SPCMD1. 7. Because the SSLKP bit in SPCMD1 is 0, this module negates the SSL signal. In addition, a next-access delay is inserted according to SPCMD1.

Notice that if such an SSL signal switching occurs, the slaves that drive the MISO signal compete, and the possibility arises of the collision of signal levels. This module in master mode references within the module the SSL signal operation for the case where the SSLKP bit is not used. Even when the CPHA bit in SPCMD is 0, this module can accurately start serial transfers by asserting the SSL signal for the next transfer. For this reason, burst transfers in master mode can be executed irrespective of CPHA bit settings (see section 17.4.8 (2), Slave Mode Operation). (e) RSPCK Delay (t1) The RSPCK delay value in master mode depends on SCKDEN bit settings in the command register (SPCMD) and on clock delay register (SPCKD) settings. This module determines the SPCMD to be referenced during serial transfer by pointer control, and determines an RSPCK delay value during serial transfer by using the SCKDEN bit in the selected SPCMD and SPCKD, as shown in table 17.8. For a definition of RSPCK delay, see section 17.4.4, Transfer Format.

This module determines the SPCMD to be referenced during serial transfer by pointer control, and determines a next-access delay value during serial transfer by using the SPNDEN bit in the selected SPCMD and SPND, as shown in table 17.10.

For this reason, when the CPHA bit is 0, the asserting of the SSL input signal triggers the start of a serial transfer. If this module detects the first RSPCK edge in an SSL signal asserted condition when the CPHA bit is 1, this module is required to start driving valid data to the MISO output signal. For this reason, when the CPHA bit is 1, the first RSPCK edge in an SSL signal asserted condition triggers the start of a serial transfer. When detecting the start of a serial transfer in a condition in which the shift register is empty, this module changes the status of the shift register to "full", so that data cannot be copied from the transmit buffer to the shift register when serial transfer is in progress. If the shift register was full before the serial transfer started, this module leaves the status of the shift register intact, in the full state. Irrespective of CPHA bit settings, this module starts driving MISO output signals at the SSL signal assertion timing. Whether the data output from this module is valid or invalid differs depending on CPHA bit settings. For details on the transfer format, see section 17.4.4, Transfer Format. The polarity of the SSL input signal depends on the setting of the SSL0P bit in the slave select polarity register (SSLP). Page 884 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (b) Section 17 Renesas Serial Peripheral Interface Terminating Serial Transfer Irrespective of the CPHA bit in the command register 0 (SPCMD0), this module terminates the serial transfer after detecting an RSPCK edge corresponding to the final sampling timing. When the receive buffer has an enough space for receive data, this module copies received data from the shift register to the receive buffer of the data register (SPDR) upon termination of the serial transfer. Irrespective of the value of the SPRF bit, this module changes the status of the shift register to "empty" upon termination of the serial transfer. If this module detects an SSL input signal negation from the beginning of serial transfer to the end of serial transfer, a mode fault error occurs (see section 17.4.6, Error Detection). The final sampling timing changes depending on the bit length of the transfer data. In slave mode, the data length depends on the settings in bits SPB3 to SPB0 bits in SPCMD0. The polarity of the SSL input signal depends on the setting in the SSL0P bit in the slave select polarity register (SSLP). For details on the transfer format, see section 17.4.4, Transfer Format. (c) Notes on Slave Operations If the CPHA bit in the command register 0(SPCMD0) is 0, this module starts serial transfers when it detects the assertion edge for an SSL input signal. In the type of configuration shown in figure 17.4 as an example, if this module is used in single-slave mode, the SSL signal is always fixed at active state. Therefore, when the CPHA bit is set to 0, this module cannot correctly start a serial transfer. To correctly execute send/receive operation in a configuration in which the SSL input signal is fixed at active state, the CPHA bit should be set to 1. When it is necessary to set the CPHA bit to 0, the SSL input signal should not be fixed. (d) Burst Transfer If the CPHA bit in the command register 0 (SPCMD0) is 1, continuous serial transfer (burst transfer) can be executed while retaining the assertion state for the SSL input signal. If the CPHA bit is 1, the period from the first RSPCK edge to the sampling timing for the reception of the final bit in an SSL signal active state corresponds to a serial transfer period. Even when the SSL input signal remains at the active level, this module can accommodate burst transfers because it can detect the start of access. If the CPHA bit is 0, for the reason given in section 17.4.8 (2) (c), Notes on Slave Operations, second and subsequent serial transfers during the burst transfer cannot be executed correctly.

This is called loopback mode. When a serial transfer is executed in loopback mode, the transmit data becomes the received data.

Assuming that SPI modes 0 to 3 are controlled by SPI mode bits [1:0], CPOL and CPHA in this document correspond to SPI mode bits 1 and 0, respectively. In this module, the initial values of CPOL and CPHA are 0 and 1, respectively, selecting SPI mode 1 as the initial mode. Notes: 1. When setting any or all of the clock delay period, QSSL negation delay period, and next-access delay period to 0, be sure to set SSLKP to 1 to select the continuous access in which QSSL is not negated. Otherwise, operation cannot be guaranteed. For the method of setting the various delay periods for the continuous access in which QSSL is not negated, see below. 2. For the continuous access in which QSSL is not negated, QSPCLK clock stopping is followed by the QSSL negation delay period, next-access delay period, and next command clock delay period, in this order. When setting any of the QSSL negation delay setting enable bit (SLNDEN), next-access delay enable bit (SPNDEN), and clock delay setting enable bit (SCKDEN) to 0, be sure to set the bit corresponding to the later period prior to the bit corresponding to the earlier period. (1) (2) (3) QSPCLK QSSL In the above figure, (1), (2), and (3) refer to the QSSL negation delay period, next-access delay period, and next command clock delay period, respectively. When setting any of these bits to 0, be sure to set (3) first. In other words, setting 1 after 0 as in {(1), (2), (3)} = {0, 0, 1}, {0, 1, 1}, {0, 1, 0} ... is prohibited. Allowed setting is {(1), (2), (3)} = {1, 1, 1}, {1, 1, 0}, {1, 0, 0}, {0, 0, 0}. If set otherwise, operation cannot be guaranteed.

The following describes 8-bit MSB first transfer in single-/dual-/quad-SPI modes when CPOL = 0 and CPHA = 0. (1) Single-SPI Mode Figure 18.2 shows the transfer format in single-SPI mode. This mode provides transmission and reception simultaneously. Since one data line is used for serial communication both in transmission and reception, the communication speed is 1 bit per QSPCLK clock cycle. Transfer data is specified using SPCMD0 to SPCMD3.

This mode only provides operation of a single direction, that is, either transmission or reception. Transmission or reception can be set using the SPI read/write access setting bit (SPRW) in SPCMD0 to SPCMD3. Transmission is carried out by write operation and reception by read operation. The IO directions of QIO1 and QIO0 are switched accordingly. Since two data lines are used for serial communication both in transmission and reception, the communication speed is 2 bits per QSPCLK clock cycle. The start bit of the transfer data is output from QIO1. Transfer data is specified using SPCMD0 to SPCMD3. For details of transfer data, see section 18.4.4, Transfer Data.

This mode provides operation of a single direction, that is, either transmission or reception. Transmission or reception can be set using the SPRW bit in SPCMD0 to SPCMD3. Transmission and reception are accomplished by writing and reading, respectively. The IO directions of QIO3 to QIO0 are switched accordingly. Since four data lines are used for serial communication both in transmission and reception, the communication speed is 4 bits per QSPCLK clock cycle. The start bit of the transfer data is output from QIO3. Transfer data is specified using SPCMD0 to SPCMD3. For details of transfer data, see section 18.4.4, Transfer Data.

In both MSB first and LSB first transfers, this module treats the specified size of data beginning at the MSB of the transmit shift register as transmit data, and the specified length of data beginning at the LSB of the receive shift register as receive data, regardless of whether the actual arrangement is MSB or LSB-first. The following sections describe MSB first and LSB first transfers in 32-bit, 16-bit, and 8-bit data units.

For data transmission, the CPU or direct memory access controller writes 32-bit transmit data to the transmit buffer (SPTXB). If the transmit shift register is empty, this module copies the data with MSB-aligned in the transmit buffer to the transmit shift register, and fills the transmit shift register. When data transmission is started, this module outputs data beginning at the MSB (bit 31) of the transmit shift register, and when the QSPCLK clock cycle required for the serial transfer of 32 bits has passed, the transmit shift register becomes empty. For data reception, data received from the data pin is stored in the receive shift register beginning at the LSB (bit 0). When the QSPCLK clock cycle required for the serial transfer of 32 bits has passed, the receive shift register becomes full. If the receive buffer (SPRXB) has a space for 32 bits or more, this module copies the 32-bit data beginning at the LSB from the receive shift register to the receive buffer, and empties the receive shift register. If the receive buffer does not have a space for 32 bits or more, data reception is not carried out. In order to start reception, the specified length of data should be read from the receive buffer to secure the space for 32 bits or more in the receive buffer. In actual transfer, this operation is repeated for the number of times defined by SPBMUL0 to SPBMUL3. Transmit buffer (SPTXB) T31 T30 T29 T28 T27 T26 ... ... ... T27 T26 ... ... ...

When the QSPCLK clock cycle required for the serial transfer of 8 bits has passed, the receive shift register becomes full. If the receive buffer (SPRXB) has a space for 8 bits or more, this module reverses the bit order in the 8-bit data, copies it beginning at the LSB from the receive shift register to the receive buffer, and empties the receive shift register. If the receive buffer does not have a space for 8 bits or more, data reception is not carried out. In order to start reception, the specified length of data should be read from the receive buffer to secure the space for 8 bits or more in the receive buffer. In actual transfer, this operation is repeated for the number of times defined by SPBMUL0 to SPBMUL3.

If access is made to SPDR, depending on the status of the transmit buffer/receive buffer, in some cases nonnormal transfers can be executed. Table 18.8 shows the relationship between non-normal transfer operations.

B SPDR is read when the receive buffer is The output data is undefined. empty. On operation A shown in table 18.8, whether SPDR can be written to or not can be checked using the transmit data byte counter bits (TXBC[5:0]) in the buffer data count register (SPBDCR). Similarly, on operation B shown in table 18.8, whether the valid data is stored in the receive buffer or not can be checked by reading the receive data byte counter bits (RXBC[5:0]) in SPBDCR.

When a power-on reset is generated, this module initializes all of the module function. When the SPE bit in SPCR is cleared to 0, this module performs the following initialization: * * * * * Suspending any serial transfer that is being executed Initializing the transmit shift register and the receive shift register Initializing the internal state machine Initializing the sequence Initializing the TEND bit in SPSR Initialization by the clearing of the SPE bit to 0 does not initialize the control bits of this module and the transmit/receive buffer. For this reason, this module can be started in the same transfer mode as prior to the initialization if the SPE bit is re-set to 1. However, clearing the SPE bit to 0 initializes the transmit shift register and the receive shift register and allows the data that is being transferred to be discarded. 18.4.7 SPI Operation The operating modes of this module are listed below. * Single-SPI mode * Dual-SPI mode/quad-SPI mode The operation in each mode is described below. (1) Single-SPI Mode (a) Starting Serial Transfer The serial transfer start conditions are: there is the specified length of data in the transmit buffer; and there is space for the specified length of data in the receive buffer. (b) Terminating Serial Transfer Irrespective of the clock setting, this module terminates the serial transfer after transmitting an QSPCLK edge corresponding to the final sampling timing. After the serial transfer is completed, receive data is copied from the receive shift register to the receive buffer. If there is not enough space for the specified length of data in the receive buffer after receive data is copied from the receive shift register to the receive buffer, another serial transfer will not be performed. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 939 of 3088 SH7268 Group, SH7269 Group Section 18 Renesas Quad Serial Peripheral Interface (c) Sequence Control In single-SPI mode, according to the sequence length that is assigned to the sequence control register (SPSCR), this module makes up a sequence comprised of a part or all of SPCMD0 to SPCMD3 and SPBMUL0 to SPBMUL3. This module contains a pointer to the SPCMD that makes up the sequence. The value of this pointer can be checked by reading SPSSR. When the SPE bit in SPCR is set to 1 and the function of this module is enabled, this module loads the pointer to the commands in SPCMD0, and incorporates the SPCMD0 and SPBMUL0 settings into the transfer format at the beginning of serial transfer. This module increments the pointer each time the next-access delay period for a data transfer that corresponds to the referenced SPCMD0 to SPCMD3 ends. Upon completion of the serial transfer that corresponds to the final command comprising the sequence, this module sets the pointer in SPCMD0, and in this manner the sequence is executed repeatedly. The following items are set in command registers SPCMD0 to SPCMD3: basic transfer data length, MSB or LSB first, clock settings, some of the bit rate settings, SPI transfer mode and transfer direction (only in dual-/quad-SPI modes), whether QSSL level is held, a clock delay period, an QSSL negation delay period, and a next-access delay period. The total amount of data to be transferred is determined by multiplying the basic length of data to be transferred by the value set with SPBMUL0 to SPBMUL3. Figure 18.11 shows an operation example when SPSCR is set to H'02, and the sequence is configured based on SPCMD0 to SPCMD2 settings. In figure 18.11, shaded areas of QMO/QMI indicate invalid data. Periods (1) to (3) in figure 18.11 indicate the followings. (1) Clock delay period (SPCKD) setting value = B'000 (1.5 QSPCLK cycles) (2) QSSL negation delay period (QSSLND) setting value = B'000 (1 QSPCLK cycle) (3) Next-access delay period (SPND) setting value = B'000 (1 QSPCLK cycle) QSPCLK (CPOL = 0, CPHA = 0) (1) (2) (3) QSSL (Low-active) QMO/QMI SPCMD0 SPCMD1 SPCMD2 Figure 18.11 Sequence Control Operation Page 940 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (d) Section 18 Renesas Quad Serial Peripheral Interface Burst Transfer This module can execute burst transfer with the following two methods in single-SPI mode. One method uses the SPB[3:0] bits in SPCMD0 to SPCMD3 and SPBMUL0 to SPBMUL3. Setting SPB[3:0] to select 8, 16, or 32 bits and setting SPBMUL0 to SPBMUL3 to select one through 4,294,967,296 allows the specified length of data to be continuously transferred for the specified times, where the length is specified by SPB[3:0] and the number of times is specified by SPBMUL0 to SPBMUL3. However, if the transmit buffer (SPTXB) becomes empty during transfer, or the receive buffer (SPRXB) has no longer a space enough to receive the specified length of data defined by SPB[3:0], the clock is stopped until transfer is resumed. Figure 18.12 shows a burst transfer example in which SPB[3:0] are set to select 32 bits and SPBMUL to select four times thus specifying 128 bits as a total transfer data amount. The following describes operations (1) to (4) in the figure. (1) First 32-bit data transfer (2) Second 32-bit data transfer (3) When the transmit buffer becomes empty or the receive buffer has no longer a space for 32 or more bits, the clock is stopped. Here, the QMO continues outputting the previous value. When data is written to the transmit buffer or an enough space is created in the receive buffer, the clock output is resumed to restart transfer.

Setting the QSSL signal level keeping bit (SSLKP) to 1 in SPCMD0 to SPCMD3 allows the QSSL signal to be kept asserted after the transfer corresponding to the pertinent command register is completed until the next transfer. Figure 18.13 shows a burst transfer example in which the QSSL signal level keeping function is used. The following describes operations (1) to (6) in the figure. (1) Clock delay period according to the SPCMD0 setting. The setting must be made so that the delay period should be at least 1.5 QSPCLK cycles for the first transfer in the burst transfer. (2) QSSL negation delay period according to the SPCMD0 setting. Since SSLKP is set to 1, QSSL is not negated even after QSSL negation delay period is over. The QSSL negation delay period depends on the SLNDEN bit setting in SPCMD0. When SLNDEN is 1, the QSSL negation delay period is determined by the SSLND setting, and the delay period is 0 QSPCLK cycle when SLNDEN is 0. (3) Next-access delay period according to the SPCMD0 setting. Since SSLKP is set to 1, QSSL is not negated even during the next-access delay period. The next-access delay period depends on the SPNDEN bit setting in SPCMD0. When SPNDEN is 1, the next-access delay period is determined by the SPND setting, and the delay period is 0 QSPCLK cycle when SPNDEN is 0. (4) Clock delay period according to the SPCMD1 setting. The clock delay period depends on the SCKDEN bit setting in SPCMD1. When SCKDEN is 1, the clock delay period is determined by the SPCKD setting, and the delay period is 0 QSPCLK cycle when SCKDEN is 0. (5) QSSL negation delay period according to the SPCMD1 setting. The setting must be made so that the delay period should be at least one QSPCLK cycle for the last transfer in the burst transfer. Since SSLKP in SPCMD1 is set to 0, QSSL is negated after QSSL negation delay period is over. (6) Next-access delay period according to the SPCMD1 setting. The setting must be made so that the delay period should be at least one QSPCLK cycle for the last transfer in the burst transfer. Be sure to set SSLKP to 0 to negate QSSL.

Periods (2) to (4) must be inserted without fail when changing the clock frequency division ratio or clock polarity through command update. When the clock frequency division ratio is changed, period (4) may be advanced or delayed with respect to the set value. At least period (2) must be inserted when changing the clock phase or transfer mode (single-/dual/quad-SPI) through command update (changing dual-/quad-SPI includes changing read/write operation).

In data transmission, the serial transfer start condition is that there is the specified length of data in the transmit buffer. In data reception, the serial transfer start condition is that there is a space for the specified length of data in the receive buffer. (b) Terminating Serial Transfer Irrespective of data transmission or reception, this module terminates the serial transfer after transmitting an QSPCLK edge corresponding to the final sampling timing. During idle cycles in dual-/quad-SPI modes, the IO pins are controlled differently depending on whether it is after write or read operation. Specifically, the IO pins output either the last output data or the fixed level depending on the register setting after write operation, whereas the IO pins are driven to the Hi-Z state after read operation. Figure 18.16 shows an example of the pin states after quad-SPI mode access is completed. The following describes operations (1) and (2) in the figure. (1) During write operation, QIO0 to QIO3 serve as output pins. Thus, when QSSL is negated upon completion of write operation, QIO0 to QIO3 output different values depending on the value of MOIFE in the SPPCR. Specifically, the IO pins output the level specified by MOIFV when MOIFE is 1, whereas the IO pins output the last output data when MOIFE is 0. (2) During read operation, QIO0 to QIO3 serve as input pins. Thus, when QSSL is negated upon completion of read operation, QIO0 to QIO3 are driven to Hi-Z state irrespective of the values of MOIFE and MOIFV. For details on the pin control in dual-/quad-SPI modes, see section 18.4.2, Pin Control.

For details on operation, see section 18.4.7 (1) (c), Sequence Control. Dual-/quad-SPI modes only provide operation of a single direction, that is, either transmission or reception for serial transfer. Transmission or reception is set using the SPI read/write access setting bit (SPRW) in SPCMD0 to SPCMD3. One of the three operating modes including dual-SPI mode, quad-SPI mode, and single-SPI mode is set using the SPI operating mode setting bits (SPIMOD[1:0]) in SPCMD0 to SPCMD3. Combining these bits allow switching single-SPI mode, dual-SPI mode transmission/reception, and quad-SPI mode transmission/reception to control sequence. Figure 18.17 shows an example of sequence configuration with transfer mode switching. QSPCLK (CPOL = 0, CPHA = 0) QSSL (Low-active) QMO/QIO0 QMI/QIO1 QIO2 Pin control register (SPPCR) setting value QIO3 Pin control register (SPPCR) setting value SPCMD0 single-SPI SPCMD1 dual-SPI transmission SPCMD2 quad-SPI reception Figure 18.17 Example of Sequence Configuration with Transfer Mode Switching R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 947 of 3088 Section 18 Renesas Quad Serial Peripheral Interface SH7268 Group, SH7269 Group Note the following when configuring a sequence in dual-/quad-SPI modes. When all the commands configuring a sequence are dual-/quad-SPI read operations, the sequential operation is continued as long as the receive buffer has an enough space for the receive data. To terminate read operation, clear the SPE bit to 0 in SPCR after receiving the required length of data, or execute write operation for the last sequence to empty the transmit buffer. (d) Burst Transfer This module can execute burst transfer with the following two methods in dual/quad SPI modes. One method uses the SPB[3:0] bits in SPCMD0 to SPCMD3 and SPBMUL0 to SPBMUL3. As with the single-SPI mode, setting SPB[3:0] to select 8, 16, or 32 bits and setting SPBMUL0 to SPBMUL3 to select one through 4,294,967,296 allows the specified length of data to be continuously transferred for the specified times, where the length is specified by SPB[3:0] and the number of times is specified by SPBMUL0 to SPBMUL3. However, if the transmit buffer (SPTXB) becomes empty during transfer, or the receive buffer (SPRXB) has no longer a space enough to receive the specified length of data defined by SPB[3:0], the clock is stopped until transfer is resumed. This method is effective to transfer a large amount of data in dual-/quad SPI modes. Figure 18.18 shows a burst transfer example in which SPB[3:0] are set to select 32 bits and SPBMUL to select four times thus specifying 128 bits as a total transfer data amount. The following describes operations (1) to (4) in the figure. (1) First 32-bit data transfer (2) Second 32-bit data transfer (3) When the transmit buffer becomes empty or the receive buffer has no longer a space for 32 or more bits, the clock is stopped. Here, when QIO3 to QIO0 serve as output pins, QIO3 to QIO0 continue outputting the previous value. When QIO3 to QIO0 serve as input pins, the inputs to QIO3 to QIO0 depend on the output value of the device to communicate with. When data is written to the transmit buffer or an enough space is created in the receive buffer, the clock output is resumed to restart transfer.

Since this method allows switching the SPI transfer modes (single-/dual-/quad-SPI) during a transfer, it is particularly convenient when used with serial flash memory, where command data is written in single-SPI mode and data to be stored in memory is written in quad-SPI mode. Note, however, that at least one delay cycle should be inserted between transfers when switching the SPI transfer modes. Figure 18.19 shows a burst transfer example in which both single-SPI and quad-SPI modes are used. The following describes operations (1) to (6) in the figure. (1) Clock delay period according to the SPCMD0 setting. The setting must be made so that the delay period should be at least 1.5 QSPCLK cycles for the first transfer in the burst transfer. (2) QSSL negation delay period according to the SPCMD0 setting. Since SSLKP in SPCMD0 is set to 1, QSSL is not negated even after QSSL negation delay period is over. The QSSL negation delay period depends on the SLNDEN bit setting in SPCMD0. When SLNDEN is 1, the QSSL negation delay period is determined by the SSLND setting, and the delay period is 0 QSPCLK cycle when SLNDEN is 0. (3) Next-access delay period according to the SPCMD0 setting. Since SSLKP is set to 1, QSSL is not negated even during the next-access delay period. The next-access delay period depends on the SPNDEN bit setting in SPCMD0. When SPNDEN is 1, the next-access delay period is determined by the SPND setting, and the delay period is 0 QSPCLK cycle when SPNDEN is 0. Up to this period, the data pin is driven according to the SPCMD0 setting. (4) Clock delay period according to the SPCMD1 setting. The clock delay period depends on the SCKDEN bit setting in SPCMD1. When SCKDEN is 1, the clock delay period is determined by the SPCKD setting, and the delay period is 0 QSPCLK cycle when SCKDEN is 0.

The setting must be made so that the delay period should be at least one QSPCLK cycle for the last transfer in the burst transfer. Since SSLKP in SPCMD1 is set to 0, QSSL is negated after QSSL negation delay period is over. (6) Next-access delay period according to the SPCMD1 setting.

Periods (2) to (4) must be inserted without fail when changing the clock frequency division ratio or clock polarity through command update. When the clock frequency division ratio is changed, period (4) may be advanced or delayed with respect to the set value. At least period (2) must be inserted when changing the clock phase or transfer mode (single-/ dual-/quad-SPI) through command update (changing dual-/quad-SPI includes changing read/write operation).

The number of connected memories can be selected using the BSZ[1:0] bits in CMNCR. Examples of system configuration with one serial flash memory connected and two serial flash memories connected are shown in figures 19.2 and 19.3, respectively.

A maximum accessible address space differs depending on the number of serial flash memories connected. In combination with DREAR, a maximum of 4 Gbytes can be accessed when one serial flash memory is connected, and a maximum of 8 Gbytes can be accessed when two memories are connected. Table 19.4 Address Map Number of Serial Flash Memories Connected Internal Address Cache Max.

Here, the fixed value set in the pertinent register is used as the upper bit value of a 32-bit address. To output serial flash addresses in 32 bits, set the ADE[3] bit in DRENR to 1, set the range of the external addresses used as the serial flash addresses to the EAC[2:0] bits in DREAR, and set the upper bit value of the 32-bit address as the fixed value to the EAV[7:0] bits in DREAR. When EAC[2:0] = 000 EAV [7:0] bits External address bits [24:0] 7 0 Serial flash address 25 24 32 0 When EAC[2:0] = 001 EAV [7:0] bits External address bits [25:0] 7 0 Serial flash address 32 26 25 0 Figure 19.4 32-Bit Address Setting Setting the ADE[3] bit in DRENR to 1 allows the serial flash address to be output using [31:0] bits. When EAC[2:0] = 000, external address bits [24:0] are valid; set the value for [32:25] bits to EAV[7:0]. When EAC[2:0] = 001, external address bits [25:0] are valid; set the value for [32:26] bits to EAV[7:1]. The address bits actually used for access depend on the number of serial flash memories connected. When one serial flash memory is connected, address bits [31:0] are used and when two memories are connected, address bits [32:1] are used. Note: When the capacity of the serial flash memory used is smaller than 4 Gbytes, keep the following point in mind. If an access spreads over the last address of the serial flash in burst mode (RBE bit in DRECR = 1), the access address does not agree with the internal address of the serial flash. To prevent this, software should appropriately manage the accessible address areas for the serial flash memory used according to the memory capacity.

The data should be accessed in word or larger units. It cannot be accessed in byte units. Data alignment when two serial flash memories are connected is shown in table 19.5.

In external address space read mode, a read access to the SPI multi I/O bus space is converted into SPI communication and data is received. After data acquisition, data is returned to the bus master that is the issuing source. For details, see section 19.5.6, External Address Space Read Mode. In SPI operating mode, arbitrary SPI communication is carried out using register settings. For details, see section 19.5.8, SPI Operating Mode. 19.5.6 External Address Space Read Mode A read access to the SPI multi I/O bus space can be converted into SPI communication in external address space read mode. Further, the commands, optional commands, and option data issued for reading can be modified using registers. In external address space read mode, either normal read operation or burst read operation can be selected. The transfer format is determined based on the common control register (CMNCR), SSL delay register (SSLDR), bit rate setting register (SPBCR), data read control register (DRCR), data read command setting register (DRCMR), data read extended address setting register (DREAR), data read option setting register (DROPR), and data read enable setting register (DRENR). (1) Normal Read Operation When the RBE bit in DRCR is set to 0, normal read operation is performed. In the normal read operation, the data of 8 bits, 16 bits, 32 bits, and 64 bits are read for respectively a byte, a word, and a longword, and a double-longword read access. Here, a byte access is enabled only when one serial flash memory is connected. After reading, the SPBSSL pin is negated. The normal read operation timing is shown in figure 19.5. t1 is the time period from SPBSSL pin assertion to SPBCLK oscillation (clock delay), t2 is the time period from transmission of the last SPBCLK edge of a transfer to SPBSSL pin negation (SPBSSL negation delay), and t3 is the time period from one transfer end to the next transfer start (next access). For details of t1, t2, and t3, see section 19.5.9, Transfer Format. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 995 of 3088 SH7268 Group, SH7269 Group Section 19 SPI Multi I/O Bus Controller SPI multi I/O bus space access t1 t2 t3 SPBSSL SPBCLK SPBMO_0 Command SPBMI_0 Address Read data 8/16/32/64 bits Flags SSLF bit TE ND bit Figure 19.5 Normal Read Operation Timing (2) Burst Read Operation When the RBE bit in DRCR is set to 1, burst read operation is performed. Read cache is enabled in the burst read operation. For read cache operation, see section 19.5.7, Read Cache. For reading bytes, words, longwords or double-longwords, the read cache is first referred to for the data. When the read cache contains the data, the data is read from the read cache without accessing the serial flash memory. When the read cache does not contain the data, burst read operation is performed in the serial flash memory and the read data is stored in the read cache. The data transfer length at that time is 64 bits x RBURST[3:0] bits and the data is always read from the 64-bit boundary. The SPBSSL pin status after data transfer can be selected by using the SSLE bit in DRCR. When the SSLE bit is set to 0, the SPBSSL pin is negated after data transfer. For an operation performed when the SSLE bit is set to 1, see (3) Burst Read Operation with Automatic SPBSSL Negation, just below. A pattern diagram of this operation and a burst read operation timing diagram when SSLE bit is set to 0 are shown in figures 19.6 and 19.7.

When accessing the next time, if the address is continuous with the previous read address, the burst read operation is performed without issuing the command, optional command, address, or option data. If the address is not continuous with the previous read address, the SPBSSL pin is once negated and the burst read operation is performed after issuing the command, optional command, address, or option data. Burst read timing diagrams for continuous address and non-continuous address are shown in figures 19.8 and 19.9.

The read cache can be used during external address space read mode and burst read operation. The read cache is configured with a line size of 64 bits and 16 entries. Read cache configuration is shown in figure 19.11. Address array Entry 0 V Tag address Data array Byte Byte Byte Entry 1 Entry 15 31 (1 + 30) bits 64 bits Figure 19.11 Read Cache Configuration (1) Address Array The V bit indicates whether the entry data is valid. When the V bit is 1, the data is valid and when V bit is 0, the data is invalid. The tag address bits hold the address used for the serial flash memory. Address bits 32 to 3 are used for the purpose. Address bits 23 to 3 are enabled when address output is 24 bits and one serial flash memory is connected; and address bits 24 to 3 are enabled when two serial flash memories are connected. Address bits 31 to 3 are enabled when address output is 32 bits and one serial flash memory is connected; and address bits 32 to 3 are enabled when two serial flash memories are connected. (2) Data Array It retains the 64-bit read data. Registration in the read cache is performed in line units.

In case of read-miss, after the 64 x RBURST (read burst length) data is read from the serial flash memory and the read cache is updated, the data is returned to the bus master. (4) Data Replacement The write pointer is used to update data. In case of read-miss, the RBURST (read burst length) portion data is replaced starting at the entry specified by the write pointer. In other words, the data is replaced in the storage order of the data. Whether data is referred to or not will not affect the replacement order of data. 19.5.8 SPI Operating Mode This module can carry out an arbitrary SPI operation by using the register settings. The transfer format is determined based on the common control register (CMNCR), SSL delay register (SSLDR), bit rate setting register (SPBCR), SPI mode control register (SMCR), SPI mode command setting register (SMCMR), SPI mode address setting register (SMADR), SPI mode option setting register (SMOPR), and SPI mode enable setting register (SMENR), SPI mode read data register (SMRDR), and SPI mode write data register (SMWDR). This mode can be used for reading the status of the serial flash memory and writing to the serial flash memory. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1001 of 3088 SH7268 Group, SH7269 Group Section 19 SPI Multi I/O Bus Controller (1) Transfer Start The transfer of data is started in the set transfer format by setting the SPIE bit in SMCR to 1. When write operation is enabled, the SPI mode write data register is transmitted to the serial flash memory. When read operation is enabled, data read from the serial flash memory is stored into the SPI mode read data register. The SPI operation timing is shown in figure 19.12.

The read data is stored into SMRDR. * Write operation: Data can be written by setting the SPIWE bit in SMCR to 1. The data stored in SMWDR is output. When the data size is set to 1 bit using the SPIDB[1:0] bits in SMENR, data can be transmitted and received by setting the SPIRE and SPIWE bits to 1. However, when the data size is set to 2 or 4 bits by using the SPIDB[1:0] bits, only one of the SPIRE and SPIWE bits should be enabled. The operation is not guaranteed if both the bits are enabled.

With this function, the transfer can be carried out continuously with the SPBSSL kept in the asserted state. Note: When the transfer data size is set to 2 or 4 bits in SPI mode, this function is not available. The data transfer timing using the SSLKP bit is shown in figure 19.13.

Similarly, in SPI operating mode, enable or disable of the command, optional command, address, option data, and transfer data can be controlled with the CDE, OCDE, ADE[3:0], OPDE[3:0], and SPIDE[3:0] bits in SMENR, respectively. However, disabling all the above parameters is prohibited in SPI operating mode. At least one of them must be enabled. For the address and option data in external address space read mode; and the address, option data, and transfer data in SPI operating mode, the enable bit setting allowed is determined according to the transfer data size. For the allowed setting combinations of the enable bits and transfer data size, refer to the description of the pertinent register. If data is disabled, that data is skipped, and input and output of the next data is carried out. The command, optional command, address, and option data are always output. In external address space read mode, data is always input; and in SPI operating mode, input and output of data is determined based on the settings of the SPIRE and SPIWE bits in SMCR.

These bits are read-only bits. (1) SSLF Bit This bit indicates the SPBSSL pin status. The status is 1 when the SPBSSL is asserted, and the status is 0 when the SPBSSL is negated. (2) TEND Bit This bit indicates whether transfer of data is in progress or the transfer of data has ended. During t1 time period, data transfer, and t2 time period, the TEND bit is read as 0 to indicate that the transfer of data is in progress. When other than the above, the TEND bit is read as 1 to indicate that transfer of data has ended. (3) Register Re-writing Timing The status of the SSLF and TEND bits determines the register re-writing timing. Table 19.10 lists the re-writing timing of various registers.

However, the configuration of the registers that control the I C bus differs partly from the Philips register configuration. 2 The I C bus interface 3 has four channels. 20.1 Features * Selection of I C format or clocked synchronous serial format 2 * Continuous transmission/reception Since the shift register, transmit data register, and receive data register are independent from each other, the continuous transmission/reception can be performed. 2 I C bus format: * Start and stop conditions generated automatically in master mode * Selection of acknowledge output levels when receiving * Automatic loading of acknowledge bit when transmitting * Bit synchronization function In master mode, the state of SCL is monitored per bit, and the timing is synchronized automatically. If transmission/reception is not yet possible, set the SCL to low until preparations are completed. * Six interrupt sources Transmit data empty (including slave-address match), transmit end, receive data full (including slave-address match), arbitration lost, NACK detection, and stop condition detection * The direct memory access controller can be activated by a transmit-data-empty request or receive-data-full request to transfer data. * Direct bus drive Two pins, SCL and SDA pins, function as NMOS open-drain outputs when the bus drive function is selected. Clocked synchronous serial format: * Four interrupt sources Transmit-data-empty, transmit-end, receive-data-full, and overrun error * The direct memory access controller can be activated by a transmit-data-empty request or receive-data-full request to transfer data.

With the clocked synchronous serial format, this 2 bit is always read as 0. With the I C bus format, this bit is set to 1 when the SDA level changes from high to low under the condition of SCL = high, assuming that the start condition has been issued. This bit is cleared to 0 when the SDA level changes from low to high under the condition of SCL = high, assuming that the stop condition has been issued. Write 1 to BBSY and 0 to SCP to issue a start condition. Follow this procedure when also re-transmitting a start condition. Write 0 in BBSY and 0 in SCP to issue a stop condition. 6 SCP 1 R/W Start/Stop Issue Condition Disable Controls the issue of start/stop conditions in master mode. To issue a start condition, write 1 in BBSY and 0 in SCP. A retransmit start condition is issued in the same way. To issue a stop condition, write 0 in BBSY and 0 in SCP. This bit is always read as 1. Even if 1 is written to this bit, the data will not be stored.

When modifying the BC[2:0] bits, this bit should be cleared to 0. In clocked synchronous serial mode, the BC[2:0] bits should not be modified. 0: When writing, values of the BC[2:0] bits are set. 1: When reading, 1 is always read.

When read, the remaining number of transfer bits 2 is indicated. With the I C bus format, the data is transferred with one addition acknowledge bit. Should be made between transfer frames. If these bits are set to a value other than B'000, the setting should be made while the SCL pin is low. The bit value returns to B'000 automatically at the end of a data transfer including the acknowledge bit. And the value becomes B'111 automatically after the stop condition detection. These bits are cleared by a power-on reset and in software standby mode and module standby mode. These bits are also cleared by setting the IICRST bit of ICCR2 to 1. With the clocked synchronous serial format, these bits should not be modified. 2 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 I C Bus Format Clocked Synchronous Serial Format 000: 9 bits 000: 8 bits 001: 2 bits 001: 1 bit 010: 3 bits 010: 2 bits 011: 4 bits 011: 3 bits 100: 5 bits 100: 4 bits 101: 6 bits 101: 5 bits 110: 7 bits 110: 6 bits 111: 8 bits 111: 7 bits Page 1031 of 3088 Section 20 I2C Bus Interface 3 20.3.4 SH7268 Group, SH7269 Group 2 I C Bus Interrupt Enable Register (ICIER) ICIER is an 8-bit readable/writable register that enables or disables interrupt sources and acknowledge bits, sets acknowledge bits to be transferred, and confirms acknowledge bits received.

When ICDRT detects the space in the shift register (ICDRS), it transfers the transmit data which is written in ICDRT to ICDRS and starts transferring data. If the next transfer data is written to ICDRT while transferring data of ICDRS, continuous transfer is possible.

When data of one byte is received, ICDRR transfers the receive data from ICDRS to ICDRR and the next data can be received.

For master transmit mode operation timing, refer to figures 20.5 and 20.6. The transmission procedure and operations in master transmit mode are described below. 1. Set the ICE bit in ICCR1 to 1. Also, set bits CKS[3:0] in ICCR1. (Initial setting) 2. Read the BBSY flag in ICCR2 to confirm that the bus is released. Set the MST and TRS bits in ICCR1 to select master transmit mode. Then, write 1 to BBSY and 0 to SCP. (Start condition issued) This generates the start condition. 3. After confirming that TDRE in ICSR has been set, write the transmit data (the first byte data show the slave address and R/W) to ICDRT. At this time, TDRE is automatically cleared to 0, and data is transferred from ICDRT to ICDRS. TDRE is set again. 4. When transmission of one byte data is completed while TDRE is 1, TEND in ICSR is set to 1 at the rise of the 9th transmit clock pulse. Read the ACKBR bit in ICIER, and confirm that the slave device has been selected. Then, write second byte data to ICDRT. When ACKBR is 1, the slave device has not been acknowledged, so issue the stop condition. To issue the stop condition, write 0 to BBSY and SCP. SCL is fixed low until the transmit data is prepared or the stop condition is issued. 5. The transmit data after the second byte is written to ICDRT every time TDRE is set. 6. Write the number of bytes to be transmitted to ICDRT. Wait until TEND is set (the end of last byte data transmission) while TDRE is 1, or wait for NACK (NACKF in ICSR = 1) from the receive device while ACKE in ICIER is 1. Then, issue the stop condition to clear TEND or NACKF. 7. When the STOP bit in ICSR is set to 1, the operation returns to the slave receive mode.

For master receive mode operation timing, refer to figures 20.7 and 20.8. The reception procedure and operations in master receive mode are shown below. 1. Clear the TEND bit in ICSR to 0, then clear the TRS bit in ICCR1 to 0 to switch from master transmit mode to master receive mode. Then, clear the TDRE bit to 0. 2. When ICDRR is read (dummy data read), reception is started, and the receive clock is output, and data received, in synchronization with the internal clock. The master device outputs the level specified by ACKBT in ICIER to SDA, at the 9th receive clock pulse. 3. After the reception of first frame data is completed, the RDRF bit in ICSR is set to 1 at the rise of 9th receive clock pulse. At this time, the receive data is read by reading ICDRR, and RDRF is cleared to 0. 4. The continuous reception is performed by reading ICDRR every time RDRF is set. If 8th receive clock pulse falls after reading ICDRR by the other processing while RDRF is 1, SCL is fixed low until ICDRR is read. 5. If next frame is the last receive data, set the RCVD bit in ICCR1 to 1 before reading ICDRR. This enables the issuance of the stop condition after the next reception. 6. When the RDRF bit is set to 1 at rise of the 9th receive clock pulse, issue the stage condition. 7. When the STOP bit in ICSR is set to 1, read ICDRR. Then clear the RCVD bit to 0. 8. The operation returns to the slave receive mode. Note: If only one byte is received, read ICDRR (dummy-read) after the RCVD bit in ICCR1 is set.

For slave transmit mode operation timing, refer to figures 20.9 and 20.10. The transmission procedure and operations in slave transmit mode are described below. 1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches. 2. When the slave address matches in the first frame following detection of the start condition, the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th clock pulse. At this time, if the 8th bit data (R/W) is 1, the TRS bit in ICCR1 and the TDRE bit in ICSR are set to 1, and the mode changes to slave transmit mode automatically. The continuous transmission is performed by writing transmit data to ICDRT every time TDRE is set. 3. If TDRE is set after writing last transmit data to ICDRT, wait until TEND in ICSR is set to 1, with TDRE = 1. When TEND is set, clear TEND. 4. Clear TRS for the end processing, and read ICDRR (dummy read). SCL is opened. 5. Clear TDRE.

Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches. 2.

At the same time, RDRF in ICSR is set to read ICDRR (dummy read). (Since the read data show the slave address and R/W, it is not used.) 3. Read ICDRR every time RDRF is set. If 8th receive clock pulse falls while RDRF is 1, SCL is fixed low until ICDRR is read.

The transfer data is output from the fall to the fall of the SCL clock, and the data at the rising edge of the SCL clock is guaranteed. The MLS bit in ICMR sets the order of data transfer, in either the MSB first or LSB first. The output level of SDA can be changed during the transfer wait, by the SDAO bit in ICCR2.

The transfer clock is output when MST in ICCR1 is 1, and is input when MST is 0. For transmit mode operation timing, refer to figure 20.14. The transmission procedure and operations in transmit mode are described below. 1. Set the ICE bit in ICCR1 to 1. Set the MST and CKS[3:0] bits in ICCR1. (Initial setting) 2. Set the TRS bit in ICCR1 to select the transmit mode. Then, TDRE in ICSR is set. 3. Confirm that TDRE has been set. Then, write the transmit data to ICDRT. The data is transferred from ICDRT to ICDRS, and TDRE is set automatically. The continuous transmission is performed by writing data to ICDRT every time TDRE is set. When changing from transmit mode to receive mode, clear TRS while TDRE is 1.

The transfer clock is output when MST in ICCR1 is 1, and is input when MST is 0. For receive mode operation timing, refer to Figure 20.15. The reception procedure and operations in receive mode are described below. 1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) 2. When the transfer clock is output, set MST to 1 to start outputting the receive clock. 3. When the receive operation is completed, data is transferred from ICDRS to ICDRR and RDRF in ICSR is set. When MST = 1, the next byte can be received, so the clock is continually output. The continuous reception is performed by reading ICDRR every time RDRF is set. When the 8th clock is risen while RDRF is 1, the overrun is detected and AL/OVE in ICSR is set. At this time, the previous reception data is retained in ICDRR. 4. To stop receiving when MST = 1, set RCVD in ICCR1 to 1, then read ICDRR. Then, SCL is fixed high after receiving the next byte data. Notes: Follow the steps below to receive only one byte with MST = 1 specified. See figure 20.16 for the operation timing. 1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) 2. Set MST = 1 while the RCVD bit in ICCR1 is 0. This causes the receive clock to be output. 3. Check if the BC2 bit in ICMR is set to 1 and then set the RCVD bit in ICCR1 to 1. This causes the SCL to be fixed to the high level after outputting one byte of the receive clock.

Figure 20.17 shows a block diagram of the noise filter circuit. The noise filter consists of three cascaded latches and a match detector. The SCL (or SDA) input signal is sampled on the peripheral clock. When NF2CYC is set to 0, this signal is not passed forward to the next circuit unless the outputs of both latches agree. When NF2CYC is set to 1, this signal is not passed forward to the next circuit unless the outputs of three latches agree. If they do not agree, the previous value is held.

Table 20.4 shows the contents of each interrupt request. Table 20.4 Interrupt Requests Interrupt Request Abbreviation Interrupt Condition I2C Bus Format Transmit data Empty TXI (TDRE = 1) * (TIE = 1) TEI (TEND = 1) * (TEIE = 1) Receive data full RXI (RDRF = 1) * (RIE = 1) STOP recognition STPI (STOP = 1) * (STIE = 1) NACK detection NAKI {(NACKF = 1) + (AL = 1)} * (NAKIE = 1) Transmit end Arbitration lost/ overrun error Clocked Synchronous Serial Format When the interrupt condition described in table 20.4 is 1, the CPU executes an interrupt exception handling. Note that a TXI or RXI interrupt can activate the direct memory access controller if the setting for direct memory access controller activation has been made. In such a case, an interrupt request is not sent to the CPU. Interrupt sources should be cleared in the exception handling. The TDRE and TEND bits are automatically cleared to 0 by writing the transmit data to ICDRT. The RDRF bit is automatically cleared to 0 by reading ICDRR. The TDRE bit is set to 1 again at the same time when the transmit data is written to ICDRT. Therefore, when the TDRE bit is cleared to 0, then an excessive data of one byte may be transmitted.

Be sure to specify a transfer rate that is at least 1/1.8 of the fastest transfer rate among the other masters. 20.7.2 Note on Master Receive Mode Reading ICDRR around the falling edge of the 8th clock might fail to fetch the receive data. In addition, when RCVD is set to 1 around the falling edge of the 8th clock and the receive buffer full, a stop condition may not be issued. Use either 1 or 2 below as a measure against the situations above. 1. In master receive mode, read ICDRR before the rising edge of the 8th clock. 2. In master receive mode, set the RCVD bit to 1 so that transfer proceeds in byte units. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1061 of 3088 Section 20 I2C Bus Interface 3 20.7.3 SH7268 Group, SH7269 Group Note on Setting ACKBT in Master Receive Mode In master receive mode operation, set ACKBT before the falling edge of the 8th SCL cycle of the last data being continuously transferred. Not doing so can lead to an overrun for the slave transmission device. 20.7.4 Note on the States of Bits MST and TRN when Arbitration is Lost When sequential bit-manipulation instructions are used to set the MST and TRS bits to select master transmission in multi-master operation, a conflicting situation where AL in ICSR = 1 but the mode is master transmit mode (MST = 1 and TRS = 1) may arise; this depends on the timing of the loss of arbitration when the bit manipulation instruction for TRS is executed. This can be avoided in either of the following ways. * In multi-master operation, use the MOV instruction to set the MST and TRS bits. * When arbitration is lost, check whether the MST and TRS bits are 0. If the MST and TRS bits have been set to a value other than 0, clear the bits to 0. 20.7.5 2 Note on I C-Bus Interface Master Receive Mode After a master receive operation is completed, confirm the falling edge of the ninth clock cycle of the SCL signal and generate a stop condition or regenerate a start condition. 20.7.6 Note on IICRST and BBSY bits When 1 is written to IICRST in ICCR2, this LSI release SCL and SDA pins. Then, if the SDA level changes from low to high under the condition of SCL = high, BBSY in ICCR2 is cleared to 0 assuming that the stop condition has been issued. 20.7.7 Note on Issuance of Stop Conditions in Master Transmit Mode while ACKE = 1 2 When a stop condition is issued in master transmit mode while the ACKE bit in the I C bus interrupt enable register (ICIER) is 1, the stop condition may not be normally output depending on the issued timing. To avoid this, recognize the falling edge of the ninth clock before issuance of the stop condition. 2 The falling edge of the ninth clock can be recognized by checking the SCLO bit in the I C control register 2 (ICCR2).

R/(W)* Transmit Underflow Error Interrupt Status Flag This status flag indicates that transmit data was supplied at a lower rate than was required. This bit is set to 1 regardless of the value of the TUIEN bit and can be cleared by writing 0 to this bit. If TUIRQ = 1 and TUIEN = 1, an interrupt occurs. If TUIRQ = 1, SSITDR did not have data written to it before it was required for transmission. This will lead to the same data being transmitted once more and a potential corruption of multi-channel data. As a result, this module will output erroneous data. Note: When an underflow error occurs, the current data in the data buffer of this module is transmitted until the next data is written.

This bit is set to 1 regardless of the value of the TOIEN bit and can be cleared by writing 0 to this bit. If TOIRQ = 1 and TOIEN = 1, an interrupt occurs. If TOIRQ = 1, SSIFTDR had data written to it while the transmit FIFO is full (TDC = H'8). This will lead to the loss of data and a potential corruption of multi-channel data. 27 RUIRQ 0 R/(W)* Receive Underflow Error Interrupt Status Flag This status flag indicates that receive data was supplied at a lower rate than was required. This bit is set to 1 regardless of the value of the RUIEN bit and can be cleared by writing 0 to this bit. If RUIRQ = 1 and RUIEN = 1, an interrupt occurs. If RUIRQ = 1, SSIFRDR was read while the receive FIFO is empty (RDC = H'0).This can cause invalid receive data to be stored, which may lead to corruption of multi-channel data. 26 ROIRQ 0 R/(W)* Receive Overflow Error Interrupt Status Flag This status flag indicates that receive data was supplied at a higher rate than was required. This bit is set to 1 regardless of the value of the ROIEN bit and can be cleared by writing 0 to this bit. If ROIRQ = 1 and ROIEN = 1, an interrupt occurs. If ROIRQ = 1, SSIRDR was not read before there was new unread data written to it. This will lead to the loss of data and a potential corruption of multi-channel data. Note: When an overflow error occurs, the current data in the data buffer of this module is overwritten by the next incoming data from the SSI interface.

[Setting condition] * Data of the number of bytes that is equal to or greater than the set receive trigger number is stored in SSIFRDR.* Note: * Since SSIFRDR is an 8-stage FIFO register, the amount of data that can be read from it while RDF = 1 is the set receive trigger number of bytes at maximum. Continuing to read data from SSIFRDR after reading all the data will result in undefined data to be read. The number of data bytes in SSIFRDR is indicated in the RDC bits in SSIFSR.

On detecting that the transmit data register (SSITDR) is empty, this module transfers the data for transmission written to SSIFTDR to SSITDR to start serial transmission, which can continue until SSIFTDR becomes empty. SSIFTDR can be written to by the CPU at any time. Note that when SSIFTDR is full of data (32 bytes), the next data cannot be written to it. If writing is attempted, it will be ignored and an overflow occurs.

When four bytes of data have been received, this module transfers the received data in the receive data register (SSIRDR) to SSIFRDR to complete reception operation. Reception can continue until 32 bytes of data have been stored to SSIFRDR. SSIFRDR can be read by the CPU but cannot be written to. Note that when SSIFRDR is read when it stores no received data, undefined values will be read and a receive underflow occurs. After SSIFRDR becomes full of received data, the data received thereafter will be lost and a receive overflow occurs.

It supports the I S compatible format as well as many more variants on these modes. (1) Slave Receiver This mode allows the module to receive serial data from another device. The clock and word select signal used for the serial data stream is also supplied from an external device. If these signals do not conform to the format specified in the configuration fields of this module, operation is not guaranteed. (2) Slave Transmitter This mode allows the module to transmit serial data to another device. The clock and word select signal used for the serial data stream is also supplied from an external device. If these signals do not conform to the format specified in the configuration fields of this module, operation is not guaranteed. (3) Slave Transceiver This mode allows serial data transmission and reception between this module and another device. The clock and word select signal used for the serial data stream is also supplied from an external device. If these signals do not conform to the format specified in the configuration fields of this module, operation is not guaranteed. (4) Master Receiver This mode allows the module to receive serial data from another device. The clock and word select signals are internally derived from the oversampling clock. The format of these signals is defined in the configuration fields of this module. If the incoming data does not follow the configured format, operation is not guaranteed. (5) Master Transmitter This mode allows the module to transmit serial data to another device. The clock and word select signals are internally derived from the oversampling clock. The format of these signals is defined in the configuration fields of this module.

When this module acts as a receiver, each word received by the serial audio bus is read in the order received from the SSIRDR register. Figures 21.6 to 21.8 show how the data on 4, 6, and 8 channels are transferred to the serial audio bus.

This mode can be set using the CONT bit in the CONT bit in the TDM mode register (SSITDMR). With this mode enabled, the SSIWS signal does not stop but continues operating even if TEN and REN bits in the control register (SSICR) are both set to 0 (transfer disabled). With this mode disabled, the SSIWS signal stops if TEN and REN bits are both set to 0. Figures 21.20 and 21.21 show the operations with WS continue mode enabled and disabled, respectively.

All required configuration fields in the control register should be defined in this mode, before this module is enabled by setting the TEN and REN bits. Setting the TEN and REN bits causes the module to enter the module enabled mode. (2) Module Enabled Mode Operation of the module in this mode is dependent on the operation mode selected. For details, refer to section 21.4.6, Transmit Operation and section 21.4.7, Receive Operation, below.

DMA control is preferred to reduce the processor load. In DMA control mode, the processor will only receive interrupts if there is an underflow or overflow of data or if the DMA transfer has been completed. The alternative method is using the interrupts that this module generates to supply data as required. When disabling this module, the clock* must be kept supplied to this module until the IIRQ bit indicates that the module is in the idle state. Figure 21.23 shows the transmit operation in DMA control mode, and figure 21.24 shows the transmit operation in interrupt control mode. Note: * Input clock from the SSISCK pin when SCKD = 0.

When an underflow or overflow occurs, the host can read the channel number and system word number to determine what point the serial audio stream has reached. In the transmitter case, the host can skip forward through the data it wants to transmit until it finds the sample data that matches what this module is expecting to transmit next, and so resynchronize with the audio data stream. In the receiver case the host CPU can store null data to make the number of receive data items consistent until it is ready to store the sample data that this module is indicating will be received next, and so resynchronize with the audio data stream. 21.4.8 Serial Bit Clock Control This function is used to control and select which clock is used for the serial bus interface. If the serial clock direction is set to input (SCKD = 0), this module is in clock slave mode and the shift register uses the bit clock that was input to the SSISCK pin. If the serial clock direction is set to output (SCKD = 1), this module is in clock master mode, and the shift register uses the oversampling clock or a divided oversampling clock as the bit clock. The oversampling clock is divided by the ratio specified by the serial oversampling clock division ratio bits (CKDV) in SSICR for use as the bit clock by the shift register. In either case the module pin, SSISCK, is the same as the bit clock.

The transmit and receive buffers in the SSIF consists of 32-bit registers that share the L and R channels. Therefore, data to be transmitted and received at the L channel may sometimes be transmitted and received at the R channel if an underflow or overflow occurs, for example, under the following condition: the control register (SSICR) has a 32-bit setting for both data word length (DWL2 to DWL0) and system word length (SWL2 to SWL0). If an error occurrence is confirmed with four types of error interrupts (transmit underflow, transmit overflow, receive underflow, and receive overflow) or the corresponding error status flag (the bits TUIRQ, TOIRQ, RUIRQ, and ROIRQ in SSISR), write 0 to the TEN or REN bit in SSICR to disable DMA transfer requests in this module, thus stopping the operation. (In this case, the direct memory access controller setting should also be stopped.) After this, write 0 to the error status flag bit to clear the error status, set the direct memory access controller again and restart the transfer. 21.5.2 Note on Changing Mode from Master Transceiver to Master Receiver If a transmit underflow occurs in master transceiver mode while WS continue mode is disabled (SSITDMR.CONT = 0) and the TEN bit in SSICR is set to 0 in order to disable transmit operation, SSIWS output is broken. In order to receive seamlessly after changing mode to master receiver mode, write dummy data to SSITDR to suppress transmit underflow. 21.5.3 Limits on TDM mode and WS Continue Mode If TDM mode or WS continue mode setting is changed, the operation of the SSISCK and SSIWS signals immediately after switching are not guaranteed. If it affects the device to be connected, do not change the setting dynamically.

(One-stage 32-bit FIFO access cannot be divided into multiple accesses.) (2) Transfer Request The following FIFO transfer requests can be issued to the CPU or direct memory access controller. * Transmit request: TDREQ (transmit FIFO transfer request) * Receive request: RDREQ (receive FIFO transfer request) The conditions to issue the transmit/receive FIFO transfer requests can be specified individually. The transmit request condition is specified with the TFWM2 to TFWM0 bits in SIFCTR, and the receive FIFO transfer request is specified with the RFWM2 to RFWM0 bits in SIFCTR. Tables 22.8 and 22.9 summarize the conditions specified by SIFCTR.

R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1151 of 3088 Section 22 Serial I/O with FIFO (2) SH7268 Group, SH7269 Group Regarding Transmit and Receive Classification The transmit request and receive request are signals indicating the state; after being set, if the state of the transmit/receive FIFO changes, they are automatically cleared by this module. When the DMA transfer is used, the signal is cleared to 0 by the direct memory access controller. If the setting condition is still satisfied after the access using the direct memory access controller, it is set to 1 again. (3) Processing when Errors Occur On occurrence of each of the errors indicated as a status in SISTR, this module performs the following operations. * Transmit FIFO underflow (TFUDF) The immediately preceding transmit data is again transmitted. * Transmit FIFO overflow (TFOVF) The contents of the transmit FIFO are protected, and the write operation causing the overflow is ignored. * Receive FIFO overflow (RFOVF) Data causing the overflow is discarded and lost. * Receive FIFO underflow (RFUDF) The read value is undefined. * FS error (FSERR) The internal counter is reset according to the sync signal in which an error occurs.

It serves to facilitate the hardware/software interface so that engineers involved in this module implementation can ensure the design is successful. Deep standby mode can be canceled by change on CRxn (PC5, PC7, PJ20, PJ22) pin. For details, refer to section 49, Power-Down Modes. 23.1.2 Scope The CAN Data Link Controller function is not described in this document. It is the responsibility of the reader to investigate the CAN Specification Document (see references). The interfaces from the CAN Controller are described, in so far as they pertain to the connection with the User Interface. The programming model is described in some detail. It is not the intention of this document to describe the implementation of the programming interface, but to simply present the interface to the underlying CAN functionality. The document places no constraints upon the implementation of this module in terms of process, packaging or power supply criteria. These issues are resolved where appropriate in implementation specifications. 23.1.3 Audience In particular this document provides the design reference for software authors who are responsible for creating a CAN application using this module. In the creation of this module user interface LSI engineers must use this document to understand the hardware requirements.

In this manual, LongWord access means the two consecutive accesses. * Micro Processor Interface (MPI) The MPI allows communication between the Renesas CPU and this module's registers/mailboxes to control the memory interface. It also contains the Wakeup Control logic that detects the CAN bus activities and notifies the MPI and the other parts of this module so that this module can automatically exit the Sleep mode. It contains registers such as MCR, IRR, GSR and IMR. * Mailbox The Mailboxes consists of RAM configured as message buffers and registers. There are 32 Mailboxes, and each mailbox has the following information. <RAM> CAN message control (identifier, rtr, ide,etc) CAN message data (for CAN Data frames) Local Acceptance Filter Mask for reception <Registers> CAN message control (dlc) Time Stamp for message reception/transmission 3-bit wide Mailbox Configuration, Disable Automatic Re-Transmission bit, AutoTransmission for Remote Request bit, New Message Control bit Tx-Trigger Time * Mailbox Control The Mailbox Control handles the following functions. For received messages, compare the IDs and generate appropriate RAM addresses/data to store messages from the CAN Interface into the Mailbox and set/clear appropriate registers accordingly. To transmit event-triggered messages, run the internal arbitration to pick the correct priority message, and load the message from the Mailbox into the Tx-buffer of the CAN Interface and set/clear appropriate registers accordingly. In the case of time-triggered transmission, compare match of Tx-Trigger time invoke loading the messages. Arbitrates Mailbox accesses between the CPU and the Mailbox Control. Contains registers such as TXPR, TXCR, TXACK, ABACK, RXPR, RFPR, UMSR and MBIMR. Page 1160 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network * Timer The Timer function is the functional entity, which provides this module with support for transmitting messages at a specific time frame and recording the result. The Timer is a 16-bit free running up counter which can be controlled by the CPU. It provides one 16-bit Compare Match Register to compare with Local Time and two 16-bit ones to compare with Cycle Time. The Compare Match Registers can generate interrupt signals and clear the Counter. The clock period of this Timer offers a wide selection derived from the system clock or can be programmed to be incremented with one nominal bit timing of CAN Bus. Contains registers such as TCNTR, TTCR0, CMAX_TEW, RFTROFF, TSR, CCR, CYCTR, RFMK, TCMR0, TCMR1, TCMR2 and TTTSEL. * CAN Interface This block conforms to the requirements for a CAN Bus Data Link Controller which is specified in Ref. [2, 4]. It fulfils all the functions of a standard DLC as specified by the OSI 7 Layer Reference model. This functional entity also provides the registers and the logic which are specific to a given CAN bus, which includes the Receive Error Counter, Transmit Error Counter, the Bit Configuration Registers and various useful Test Modes. This block also contains functional entities to hold the data received and the data to be transmitted for the CAN Data Link Controller.

Page 1168 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (1) Section 23 Controller Area Network Message Control Field STDID[10:0]: These bits set the identifier (standard identifier) of data frames and remote frames. EXTID[17:0]: These bits set the identifier (extended identifier) of data frames and remote frames. RTR (Remote Transmission Request bit): Used to distinguish between data frames and remote frames. This bit is overwritten by received CAN Frames depending on Data Frames or Remote Frames. Important: Please note that, when ATX bit is set with the setting MBC = 001(bin), the RTR bit will never be set. When a Remote Frame is received, the CPU can be notified by the corresponding RFPR set or IRR[2] (Remote Frame Receive Interrupt), however, as this module needs to transmit the current message as a Data Frame, the RTR bit remains unchanged. Important: In order to support automatic answer to remote frame when MBC = 001 (bin) is used and ATX = 1 the RTR flag must be programmed to zero to allow data frame to be transmitted. Note: when a Mailbox is configured to send a remote frame request the DLC used for transmission is the one stored into the Mailbox. RTR Description 0 Data frame 1 Remote frame IDE (Identifier Extension bit): Used to distinguish between the standard format and extended format of CAN data frames and remote frames. IDE Description 0 Standard format 1 Extended format R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1169 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network * Mailbox-0 Bit: Initial value: R/W: 15 14 13 12 11 0 0 NMC 0 0 0 R 0 R 0 R/W 0 R 0 R 10 9 8 MBC[2:0] 1 R/W 7 6 5 4 0 0 0 0 3 2 1 0 DLC[3:0] 1 R 1 R/W 0 R 0 R 0 R 0 R 0 R/W 0 R/W 0 R/W 0 R/W 9 8 7 6 5 4 3 2 1 0 0 0 0 0 0 R 0 R 0 R 0 R Note: MBC[1] of MB0 is always "1". * Mailbox-31 to 1 Bit: Initial value: R/W: 15 14 13 12 11 0 0 NMC ATX DART 0 R 0 R 0 R/W 0 R/W 0 R/W 10 MBC[2:0] 1 R/W 1 R/W 1 R/W DLC[3:0] 0 R/W 0 R/W 0 R/W 0 R/W NMC (New Message Control): When this bit is set to '0', the Mailbox of which the RXPR or RFPR bit is already set does not store the new message but maintains the old one and sets the UMSR correspondent bit. When this bit is set to '1', the Mailbox of which the RXPR or RFPR bit is already set overwrites with the new message and sets the UMSR correspondent bit. Important: Please note that if a remote frame is overwritten with a data frame or vice versa could be that both RXPR and RFPR flags (together with UMSR) are set for the same Mailbox. In this case the RTR bit within the Mailbox Control Field should be relied upon. Important: Please note that when the Time Triggered mode is used NMC needs to be set to `1' for Mailbox 31 to allow synchronization with all incoming reference messages even when RXPR[31] is not cleared. NMC Description 0 Overrun mode (Initial value) 1 Overwrite mode Page 1170 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network ATX (Automatic Transmission of Data Frame): When this bit is set to `1' and a Remote Frame is received into the Mailbox DLC is stored. Then, a Data Frame is transmitted from the same Mailbox using the current contents of the message data and updated DLC by setting the corresponding TXPR automatically. The scheduling of transmission is still governed by ID priority or Mailbox priority as configured with the Message Transmission Priority control bit (MCR.2). In order to use this function, MBC[2:0] needs to be programmed to be `001' (Bin). When a transmission is performed by this function, the DLC (Data Length Code) to be used is the one that has been received. Application needs to guarantee that the DLC of the remote frame correspond to the DLC of the data frame requested. Important: When ATX is used and MBC = 001 (Bin) the filter for the IDE bit cannot be used since ID of remote frame has to be exactly the same as that of data frame as the reply message. Important: Please note that, when this function is used, the RTR bit will never be set despite receiving a Remote Frame. When a Remote Frame is received, the CPU will be notified by the corresponding RFPR set, however, as this module needs to transmit the current message as a Data Frame, the RTR bit remains unchanged. Important: Please note that in case of overrun condition (UMSR flag set when the Mailbox has its NMC = 0) the message received is discarded. In case a remote frame is causing overrun into a Mailbox configured with ATX = 1, the transmission of the corresponding data frame may be triggered only if the related PFPR flag is cleared by the CPU when the UMSR flag is set. In such case PFPR flag would get set again. ATX Description 0 Automatic Transmission of Data Frame disabled (Initial value) 1 Automatic Transmission of Data Frame enabled DART (Disable Automatic Re-Transmission): When this bit is set, it disables the automatic retransmission of a message in the event of an error on the CAN bus or an arbitration lost on the CAN bus. In effect, when this function is used, the corresponding TXCR bit is automatically set at the start of transmission. When this bit is set to '0', this module tries to transmit the message as many times as required until it is successfully transmitted or it is cancelled by the TXCR. DART Description 0 Re-transmission enabled (Initial value) 1 Re-Transmission disabled R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1171 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network MBC[2:0] (Mailbox Configuration): These bits configure the nature of each Mailbox as follows. When MBC = 111 (Bin), the Mailbox is inactive, i.e., it does not receive or transmit a message regardless of TXPR or other settings. The MBC = '110', '101' and '100' settings are prohibited. When the MBC is set to any other value, the LAFM field becomes available. Please don't set TXPR when MBC is set as reception as there is no hardware protection, and TXPR will remain set. MBC[1] of Mailbox-0 is fixed to "1" by hardware. This is to ensure that MB0 cannot be configured to transmit Messages.

When ATX = 1 is used the filter for IDE must not be used. Page 1172 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network DLC[3:0] (Data Length Code): These bits encode the number of data bytes from 0,1, 2, ... 8 that will be transmitted in a data frame. Please note that when a remote frame request is transmitted the DLC value to be used must be the same as the DLC of the data frame that is requested.

LAFM: When MBC is set to 001, 010, 011(Bin), this field is used as LAFM Field. It allows a Mailbox to accept more than one identifier. The LAFM is comprised of two 16-bit read/write areas as follows. 15 IDE_ H'104 + N*32 LAFM 14 13 0 0 H'106 + N*32 12 11 10 9 8 7 6 5 4 3 2 STDID_LAFM[10:0] EXTID_LAFM[15:0] 1 0 EXTID_ LAFM[17:16] Word/LW LAFM Field Word Figure 23.4 Acceptance filter If a bit is set in the LAFM, then the corresponding bit of a received CAN identifier is ignored when this module searches a Mailbox with the matching CAN identifier. If the bit is cleared, then the corresponding bit of a received CAN identifier must match to the STDID/IDE/EXTID set in the mailbox to be stored. The structure of the LAFM is same as the message control in a Mailbox. If this function is not required, it must be filled with '0'. Important: This module starts to find a matching identifier from Mailbox-31 down to Mailbox-0. As soon as this module finds one matching, it stops the search. The message will be stored or not depending on the NMC and RXPR/RFPR flags. This means that, even using LAFM, a received message can only be stored into 1 Mailbox. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1173 of 3088 Section 23 Controller Area Network SH7268 Group, SH7269 Group Important: When a message is received and a matching Mailbox is found, the whole message is stored into the Mailbox. This means that, if the LAFM is used, the STDID, RTR, IDE and EXTID may differ to the ones originally set as they are updated with the STDID, RTR, IDE and EXTID of the received message. STD_LAFM[10:0] -- Filter mask bits for the CAN base identifier [10:0] bits. STD_LAFM[10:0] Description 0 Corresponding STD_ID bit is cared 1 Corresponding STD_ID bit is "don't cared" EXT_LAFM[17:0] -- Filter mask bits for the CAN Extended identifier [17:0] bits. EXT_LAFM[17:0] Description 0 Corresponding EXT_ID bit is cared 1 Corresponding EXT_ID bit is "don't cared" IDE_LAFM -- Filter mask bit for the CAN IDE bit. IDE_LAFM Description 0 Corresponding IDE bit is cared 1 Corresponding IDE bit is "don't cared" (3) Message Data Fields Storage for the CAN message data that is transmitted or received. MSG_DATA[0] corresponds to the first data byte that is transmitted or received. The bit order on the CAN bus is bit 7 through to bit 0. When CMAX!= 3'b111/MBC[30] = 3'b000 and TXPR[30] is set, Mailbox-30 is configured as transmission of time reference. Its DLC must be greater than 0 and its RTR must be zero (as specified for TTCAN Level 1) so that the Cycle_count (CCR register) is embedded in the first byte of the data field instead of MSG_DATA_0[5:0] when this Mailbox starts transmission. This function shall be used when this module is enabled to work in TTCAN mode to perform a Potential Time Master role to send the Time reference message. MSG_DATA_0[7:6] is still transmitted as stored in the Mailbox. User can set MSG_DATA_0[7] when a Next_is_Gap needs to be transmitted. Page 1174 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network Please note that the CCR value is only embedded on the frame transmitted but not stored back into Mailbox 30. When CMAX!= 3'b111, MBC[31] = 3'b011 and TXPR[31] is cleared, Mailbox-31 is configured as reception of time reference. When a valid reference message is received (DLC > 0) this module performs internal synchronisation (modifying its RFMK and basic cycle CCR).

For messages received into Mailboxes 30 and 31, Timestamp captures the TCNTR (Timer Counter Register) value at SOF. Message Transmit: For transmitted messages of Mailbox-15 to 1, Timestamp always captures the CYCTR (Cycle Time Register) value or Cycle_Counter CCR[5:0] + CYCTR[15:6] value, depending on the programmed value in the bit 14 of TTCR0 (Timer Trigger Control Register 0), at SOF. For messages transmitted from Mailboxes30 and 31, Timestamp captures the TCNTR (Timer Counter Register) value at SOF. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1175 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network Important: Please note that the TimeStamp is stored in a temporary register. Only after a successful transmission or reception the value is then copied into the related Mailbox field. The TimeStamp may also be updated if the CPU clears RXPR[N]/RFPR[N] at the same time that UMSR[N] is set in overrun, however it can be read properly before clearing RXPR[N]/RFPR[N]. (5) Tx-Trigger Time (TTT) and Time Trigger control For Mailbox-29 to 24, when MBC is set to 000 (Bin) in time trigger mode (CMAX!= 3'b111), TxTrigger Time works as Time_Mark to determine the boundary between time windows. The TTT and TT control are comprised of two 16-bit read/write areas as follows. Mailbox-30 doesn't have TT control and works as Time_Ref. Mailbox 30 to 24 can be used for reception if not used for transmission in TT mode. However they cannot join the event trigger transmission queue when the TT mode is used. * Tx-Trigger Time Bit: 15 14 13 12 11 10 TTT15 TTT14 TTT13 TTT12 TTT11 TTT10 Initial value: R/W: 0 R/W 0 R/W 0 R/W 9 8 7 6 5 4 3 2 1 0 TTT9 TTT8 TTT7 TTT6 TTT5 TTT4 TTT3 TTT2 TTT1 TTT0 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 12 11 10 9 8 7 6 5 4 3 2 1 0 0 0 0 0 0 0 R 0 R 0 R 0 R 0 R * Time Trigger control Bit: 15 14 13 TTW[1:0] Initial value: R/W: 0 R/W Offset[5:0] 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W rep_factor[2:0] 0 R/W 0 R/W 0 R/W The following figure shows the differences between all Mailboxes supporting Time Triggered mode.

Please note that once a merged arbitrating window is opened by TTW = 2'b10, the window must be closed by TTW = 2'b11. Several messages with TTW = 2'b10 may be used within the start and the end of a merged arbitrating window. TTW[1] TTW[0] Description 0 0 Exclusive window (initial value) 0 1 Arbitrating window 1 0 Start of merged arbitrating window 1 1 End of merged arbitrating window The first 16-bit area specifies the time that triggers the transmission of the message in cycle time. The second 16-bit area specifies the basic cycle in the system matrix where the transmission must start (Offset) and the frequency for periodic transmission. When the internal TTT register matches to the CYCTR value, and the internal Offset matches to CCR value transmission is attempted from the corresponding Mailbox. In order to enable this function, the CMAX (Cycle Maximum Register) must be set to a value different from 3'b111, the Timer (TCNTR) must be running (TTCR0 bit15 = 1), the corresponding MBC must be set to 3'b000 and the corresponding TXPR bit must be set. Once TXPR is set by S/W, this module does not clear the corresponding TXPR bit (among Mailbox-30 to 24) to carry on performing the periodic transmission.

Bit 14 -- Auto Halt Bus Off (MCR14): If both this bit and MCR6 are set, MCR1 is automatically set as soon as this module enters BusOff. Bit14: MCR14 Description 0 This module remains in BusOff for normal recovery sequence (128 x 11 Recessive Bits) (Initial value) 1 This module moves directly into Halt Mode after it enters BusOff if MCR6 is set. This bit can be modified only in reset mode. Bit 13 -- Reserved. The written value should always be `0' and the returned value is '0'. Bit 12 -- Reserved. The written value should always be `0' and the returned value is '0'. Bit 11 -- Reserved. The written value should always be `0' and the returned value is '0'. Bit 10 - 8 -- Test Mode (TST[2:0]): This bit enables/disables the test modes. Please note that before activating the Test Mode it is requested to move this module into Halt mode or Reset mode. This is to avoid that the transition to Test Mode could affect a transmission/reception in progress. For details, please refer to section 23.4.1, Test Mode Settings. Please note that the test modes are allowed only for diagnosis and tests and not when this module is used in normal operation. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1181 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network Bit10: TST2 Bit9: TST1 Bit8: TST0 Description 0 0 0 Normal Mode (initial value) 0 0 1 Listen-Only Mode (Receive-Only Mode) 0 1 0 Self Test Mode 1 (External) 0 1 1 Self Test Mode 2 (Internal) 1 0 0 Write Error Counter 1 0 1 Error Passive Mode 1 1 0 Setting prohibited 1 1 1 Setting prohibited Bit 7 -- Auto-wake Mode (MCR7): MCR7 enables or disables the Auto-wake mode. If this bit is set, this module automatically cancels the sleep mode (MCR5) by detecting CAN bus activity (dominant bit). If MCR7 is cleared this module does not automatically cancel the sleep mode. This module cannot store the message that wakes it up. Note: This bit can be modified only Reset or Halt mode. Bit7: MCR7 Description 0 Auto-wake by CAN bus activity disabled (Initial value) 1 Auto-wake by CAN bus activity enabled Bit 6 -- Halt during Bus Off (MCR6): MCR6 enables or disables entering Halt mode immediately when MCR1 is set during Bus Off. This bit can be modified only in Reset or Halt mode. Please note that when Halt is entered in Bus Off the CAN engine is also recovering immediately to Error Active mode. Bit6: MCR6 Description 0 If MCR[1] is set, this module will not enter Halt mode during Bus Off but wait up to end of recovery sequence (Initial value) 1 Enter Halt mode immediately during Bus Off if MCR[1] or MCR[14] are asserted. Page 1182 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network Bit 5 -- Sleep Mode (MCR5): Enables or disables Sleep mode transition. If this bit is set, while this module is in halt mode, the transition to sleep mode is enabled. Setting MCR5 is allowed after entering Halt mode. The two Error Counters (REC, TEC) will remain the same during Sleep mode. This mode will be exited in two ways: 1. by writing a '0' to this bit position, 2. or, if MCR[7] is enabled, after detecting a dominant bit on the CAN bus. If Auto wake up mode is disabled, this module will ignore all CAN bus activities until the sleep mode is terminated. When leaving this mode this module will synchronise to the CAN bus (by checking for 11 recessive bits) before joining CAN Bus activity. This means that, when the No.2 method is used, this module will miss the first message to receive. CAN transceivers stand-by mode will also be unable to cope with the first message when exiting stand by mode, and the S/W needs to be designed in this manner. In sleep mode only the following registers can be accessed: MCR, GSR, IRR and IMR. Important: This module is required to be in Halt mode before requesting to enter in Sleep mode. That allows the CPU to clear all pending interrupts before entering sleep mode. Once all interrupts are cleared this module must leave the Halt mode and enter Sleep mode simultaneously (by writing MCR[5] = 1 and MCR[1] = 0 at the same time). Bit 5: MCR5 Description 0 This module sleep mode released (Initial value) 1 Transition to this module sleep mode enabled Bit 4 -- Reserved. The written value should always be '0' and the returned value is '0'. Bit 3 -- Reserved. The written value should always be '0' and the returned value is '0'. Bit 2 -- Message Transmission Priority (MCR2): MCR2 selects the order of transmission for pending transmit data. If this bit is set, pending transmit data are sent in order of the bit position in the Transmission Pending Register (TXPR). The order of transmission starts from Mailbox-31 as the highest priority, and then down to Mailbox-1 (if those mailboxes are configured for transmission). Please note that this feature cannot be used for time trigger transmission of the Mailboxes 24 to 30. If MCR2 is cleared, all messages for transmission are queued with respect to their priority (by running internal arbitration). The highest priority message has the Arbitration Field (STDID + IDE bit + EXTID (if IDE = 1) + RTR bit) with the lowest digital value and is transmitted first. The internal arbitration includes the RTR bit and the IDE bit (internal arbitration works in the same R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1183 of 3088 Section 23 Controller Area Network SH7268 Group, SH7269 Group way as the arbitration on the CAN Bus between two CAN nodes starting transmission at the same time). This bit can be modified only in Reset or Halt mode. Bit 2: MCR2 Description 0 Transmission order determined by message identifier priority (Initial value) 1 Transmission order determined by mailbox number priority (Mailbox-31 Mailbox-1) Bit 1--Halt Request (MCR1): Setting the MCR1 bit causes the CAN controller to complete its current operation and then enter Halt mode (where it is cut off from the CAN bus). This module remains in Halt Mode until the MCR1 is cleared. During the Halt mode, the CAN Interface does not join the CAN bus activity and does not store messages or transmit messages. All the user registers (including Mailbox contents and TEC/REC) remain unchanged with the exception of IRR0 and GSR4 which are used to notify the halt status itself. If the CAN bus is in idle or intermission state regardless of MCR6, this module will enter Halt Mode within one Bit Time. If MCR6 is set, a halt request during Bus Off will be also processed within one Bit Time. Otherwise the full Bus Off recovery sequence will be performed beforehand. Entering the Halt Mode can be notified by IRR0 and GSR4. If both MCR14 and MCR6 are set, MCR1 is automatically set as soon as this module enters BusOff. In the Halt mode, this module configuration can be modified with the exception of the Bit Timing setting, as it does not join the bus activity. MCR[1] has to be cleared by writing a '0' in order to rejoin the CAN bus. After this bit has been cleared, this module waits until it detects 11 recessive bits, and then joins the CAN bus. Notes: 1. After issuing a Halt request the CPU is not allowed to set TXPR or TXCR or clear MCR1 until the transition to Halt mode is completed (notified by IRR0 and GSR4). After MCR1 is set this can be cleared only after entering Halt mode or through a reset operation (SW or HW). 2. Transition into or recovery from HALT mode, is only possible if the BCR1 and BCR0 registers are configured to a proper Baud Rate. Bit 1: MCR1 Description 0 Clear Halt request (Initial value) 1 Halt mode transition request Page 1184 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network Bit 0 -- Reset Request (MCR0): Controls resetting of this module. When this bit is changed from '0' to '1' this module controller enters its reset routine, re-initialising the internal logic, which then sets GSR3 and IRR0 to notify the reset mode. During a re-initialisation, all user registers are initialised. This module can be re-configured while this bit is set. This bit has to be cleared by writing a '0' to join the CAN bus. After this bit is cleared, this module waits until it detects 11 recessive bits, and then joins the CAN bus. The Baud Rate needs to be set up to a proper value in order to sample the value on the CAN Bus. After Power On Reset, this bit and GSR3 are always set. This means that a reset request has been made and this module needs to be configured. The Reset Request is equivalent to a Power On Reset but controlled by Software. Bit 0: MCR0 Description 0 Clear Reset Request 1 CAN Interface reset mode transition request (Initial value) (2) General Status Register (GSR) The General Status Register (GSR) is a 16-bit read-only register that indicates the status of this module. * GSR (Address = H'002) Bit: Initial value: R/W: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 - - - - - - - - - - GSR5 GSR4 GSR3 GSR2 GSR1 GSR0 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 1 R 1 R 0 R 0 R Bits 15 to 6: Reserved. The written value should always be '0' and the returned value is '0'. Bit 5 -- Error Passive Status Bit (GSR5): Indicates whether the CAN Interface is in Error Passive or not. This bit will be set high as soon as this module enters the Error Passive state and is cleared when the module enters again the Error Active state (this means the GSR5 will stay high during Error Passive and during Bus Off). Consequently to find out the correct state both GSR5 and GSR0 must be considered.

The timing to set TXACK is different from the time to clear GSR2. TXACK th rd is set at the 7 bit of End Of Frame. GSR2 is set at the 3 bit of intermission if there are no more messages ready to be transmitted. It is also set by arbitration lost, bus idle, reception, reset or halt transition.

It indicates that: The Timer (TCNTR) has overrun when this module is working in event-trigger mode (including test modes) R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1193 of 3088 Section 23 Controller Area Network SH7268 Group, SH7269 Group Time reference message with Next_is_Gap set has been received when working in timetrigger mode. Please note that when a Next_is_Gap is received the application is responsible to stop all transmission at the end of the current basic cycle (including test modes) Message error has occurred when in test mode. Note: If a Message Overload condition occurs when in Test Mode, then this bit will not be set. Bit 13: IRR13 Description 0 Timer (TCNTR) has not overrun in event-trigger mode (including test modes) (Initial value) Time reference message with Next_is_Gap has not been received in timetrigger mode (including test modes) Message error has not occurred in test mode [Clearing condition] Writing 1 1 [Setting condition] Timer (TCNTR) has overrun and changed from H'FFFF to H'0000 in eventtrigger mode (including test modes) Time reference message with Next_is_Gap has been received in time-trigger mode (including test modes) Message error has occurred in test mode Bit 12 - Bus activity while in sleep mode (IRR12): IRR12 indicates that a CAN bus activity is present. While this module is in sleep mode and a dominant bit is detected on the CAN bus, this bit is set. This interrupt is cleared by writing a '1' to this bit position. Writing a '0' has no effect. If auto wakeup is not used and this interrupt is not requested it needs to be disabled by the related interrupt mask register. If auto wake up is not used and this interrupt is requested it should be cleared only after recovering from sleep mode. This is to avoid that a new falling edge of the reception line causes the interrupt to get set again. Please note that the setting time of this interrupt is different from the clearing time of GSR4.

When CCR = 0, this bit is set at the successful completion of reception/transmission of time reference message. Please note that when CMAX = 0 this interrupt is set at every basic cycle. Bit 10: IRR10 Description 0 A new system matrix is not starting (initial value) [Clearing condition] Writing 1 1 Cycle counter reached zero. [Setting condition] Reception/transmission of time reference message is successfully completed when CMAX!= 3'b111 and CCR = 0 Bit 9 - Message Overrun/Overwrite Interrupt Flag (IRR9): Flag indicating that a message has been received but the existing message in the matching Mailbox has not been read as the corresponding RXPR or RFPR is already set to '1' and not yet cleared by the CPU. The received message is either abandoned (overrun) or overwritten dependant upon the NMC (New Message Control) bit. This bit is cleared when all bit in UMSR (Unread Message Status Register) are cleared (by writing '1') or by setting MBIMR (MailBox interrupt Mast Register) for all UMSR flag set. It is also cleared by writing a '1' to all the correspondent bit position in MBIMR. Writing to this bit position has no effect. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1195 of 3088 Section 23 Controller Area Network SH7268 Group, SH7269 Group Bit 9: IRR9 Description 0 No pending notification of message overrun/overwrite [Clearing condition] Clearing of all bit in UMSR/setting MBIMR for all UMSR set (initial value) 1 A receive message has been discarded due to overrun condition or a message has been overwritten [Setting condition] Message is received while the corresponding RXPR and/or RFPR = 1 and MBIMR = 0 Bit 8 - Mailbox Empty Interrupt Flag (IRR8): This bit is set when one of the messages set for transmission has been successfully sent (corresponding TXACK flag is set) or has been successfully aborted (corresponding ABACK flag is set). In Event Triggered mode the related TXPR is also cleared and this mailbox is now ready to accept a new message data for the next transmission. In Time Trigger mode TXPR for the Mailboxes from 30 to 24 is not cleared after a successful transmission in order to keep transmitting at each programmed basic cycle. In effect, this bit is set by an OR'ed signal of the TXACK and ABACK bits not masked by the corresponding MBIMR flag. Therefore, this bit is automatically cleared when all the TXACK and ABACK bits are cleared. It is also cleared by writing a '1' to all the correspondent bit position in MBIMR. Writing to this bit position has no effect. Bit 8: IRR8 Description 0 Messages set for transmission or transmission cancellation request NOT progressed.

Note that in the condition of transmission being prevented, such as listen only mode, an Overload Frame will NOT be transmitted, but IRR7 will still be set. IRR7 remains asserted until reset by writing a '1' to this bit position - writing a '0' has no effect. Bit 7: IRR7 Description 0 [Clearing condition] Writing 1 (Initial value) 1 [Setting conditions] Overload condition detected Bit 6 - Bus Off Interrupt Flag (IRR6): This bit is set when this module enters the Bus-off state or when this module leaves Bus-off and returns to Error-Active. The cause therefore is the existing condition TEC 256 at the node or the end of the Bus-off recovery sequence (128X11 consecutive recessive bits) or the transition from Bus Off to Halt (automatic or manual). This bit remains set even if this module node leaves the bus-off condition, and needs to be explicitly cleared by S/W. The S/W is expected to read the GSR0 to judge whether this module is in the busoff or error active status. It is cleared by writing a '1' to this bit position even if the node is still bus-off. Writing a '0' has no effect. Bit 6: IRR6 Description 0 [Clearing condition] Writing 1 (Initial value) 1 Enter Bus off state caused by transmit error or Error Active state returning from Bus-off [Setting condition] When TEC becomes 256 or End of Bus-off after 128X11 consecutive recessive bits or transition from Bus Off to Halt Bit 5 - Error Passive Interrupt Flag (IRR5): Interrupt flag indicating the error passive state caused by the transmit or receive error counter or by Error Passive forced by test mode. This bit is reset by writing a '1' to this bit position, writing a '0' has no effect. If this bit is cleared the node may still be error passive. Please note that the SW needs to check GSR0 and GSR5 to judge whether this module is in Error Passive or Bus Off status. Bit 5: IRR5 Description 0 [Clearing condition] Writing 1 (Initial value) 1 Error passive state caused by transmit/receive error [Setting condition] When TEC 128 or REC 128 or Error Passive test mode is used R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1197 of 3088 Section 23 Controller Area Network SH7268 Group, SH7269 Group Bit 4 - Receive Error Counter Warning Interrupt Flag (IRR4): This bit becomes set if the receive error counter (REC) reaches a value greater than 95 when this module is not in the Bus Off status. The interrupt is reset by writing a '1' to this bit position, writing '0' has no effect. Bit 4: IRR4 Description 0 [Clearing condition] Writing 1 (Initial value) 1 Error warning state caused by receive error [Setting condition] When REC 96 and this module is not in Bus Off Bit 3 - Transmit Error Counter Warning Interrupt Flag (IRR3): This bit becomes set if the transmit error counter (TEC) reaches a value greater than 95. The interrupt is reset by writing a '1' to this bit position, writing '0' has no effect. Bit 3: IRR3 Description 0 [Clearing condition] Writing 1 (Initial value) 1 Error warning state caused by transmit error [Setting condition] When TEC 96 Bit 2 - Remote Frame Receive Interrupt Flag (IRR2): Flag indicating that a remote frame has been received in a mailbox. This bit is set if at least one receive mailbox, with related MBIMR not set, contains a remote frame transmission request. This bit is automatically cleared when all bits in the Remote Frame Receive Pending Register (RFPR), are cleared. It is also cleared by writing a '1' to all the correspondent bit position in MBIMR. Writing to this bit has no effect. Bit 2: IRR2 Description 0 [Clearing condition] Clearing of all bits in RFPR (Initial value) 1 At least one remote request is pending [Setting condition] When remote frame is received and the corresponding MBIMR = 0 Bit 1 - Data Frame Received Interrupt Flag (IRR1): IRR1 indicates that there are pending Data Frames received. If this bit is set at least one receive mailbox contains a pending message. This bit is cleared when all bits in the Data Frame Receive Pending Register (RXPR) are cleared, i.e. there is no pending message in any receiving mailbox. It is in effect a logical OR of the RXPR flags from each configured receive mailbox with related MBIMR not set. It is also cleared by writing a '1' to all the correspondent bit position in MBIMR. Writing to this bit has no effect.

It can indicate that: 1. Reset mode has been entered after a SW (MCR0) or HW reset 2. Halt mode has been entered after a Halt request (MCR1) 3. Sleep mode has been entered after a sleep request (MCR5) has been made while in Halt mode. The GSR may be read after this bit is set to determine which state this module is in. Important: When a Sleep mode request needs to be made, the Halt mode must be used beforehand. Please refer to the MCR5 description and Figure 23.15 Halt Mode/Sleep Mode. IRR0 is set by the transition from "0" to "1" of GSR3 or GSR4 or by transition from Halt mode to Sleep mode. So, IRR0 is not set if this module enters Halt mode again right after exiting from Halt mode, without GSR4 being cleared. Similarly, IRR0 is not set by direct transition from Sleep mode to Halt Request. At the transition from Halt/Sleep mode to Transition/Reception, clearing GSR4 needs (one-bit time - TSEG2) to (one-bit time * 2 - TSEG2). In the case of Reset mode, IRR0 is set, however, the interrupt to the CPU is not asserted since IMR0 is automatically set by initialisation. Bit 0: IRR0 Description 0 [Clearing condition] Writing 1 1 Transition to S/W reset mode or transition to halt mode or transition to sleep mode (Initial value) [Setting condition] When reset/halt/sleep transition is completed after a reset (MCR0 or HW) or Halt mode (MCR1) or Sleep mode (MCR5) is requested R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1199 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network (5) Interrupt Mask Register (IMR) The interrupt mask register is a 16 bit register that protects all corresponding interrupts in the Interrupt Request Register (IRR) from generating an output signal on the IRQ. An interrupt request is masked if the corresponding bit position is set to '1'. This register can be read or written at any time. The IMR directly controls the generation of IRQ, but does not prevent the setting of the corresponding bit in the IRR. * IMR (Address = H'00A) Bit: 15 14 13 12 11 10 IMR15 IMR14 IMR13 IMR12 IMR11 IMR10 Initial value: R/W: 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 9 8 7 6 5 4 3 2 1 0 IMR9 IMR8 IMR7 IMR6 IMR5 IMR4 IMR3 IMR2 IMR1 IMR0 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W Bit 15 to 0: Maskable interrupt sources corresponding to IRR[15:0] respectively. When a bit is set, the interrupt signal is not generated, although setting the corresponding IRR bit is still performed. Bit[15:0]: IMRn Description 0 Corresponding IRR is not masked (IRQ is generated for interrupt conditions) 1 Corresponding interrupt of IRR is masked (Initial value) (6) Transmit Error Counter (TEC) and Receive Error Counter (REC) The Transmit Error Counter (TEC) and Receive Error Counter (REC) is a 16-bit read/(write) register that functions as a counter indicating the number of transmit/receive message errors on the CAN Interface. The count value is stipulated in the CAN protocol specification Refs. [1], [2], [3] and [4]. When not in (Write Error Counter) test mode this register is read only, and can only be modified by the CAN Interface. This register can be cleared by a Reset request (MCR0) or entering to bus off. In Write Error Counter test mode (i.e. TST[2:0] = 3'b100), it is possible to write to this register. The same value can only be written to TEC/REC, and the value written into TEC is set to TEC and REC. When writing to this register, this module needs to be put into Halt Mode. This feature is only intended for test purposes.

In the case of 16-bit bus interface, Long Word access is carried out as two consecutive word accesses. <Longword Write Operation> <upper word write> <lower word write> 16-bit Peripheral bus 16-bit Peripheral bus consecutive access Temp TXPR1 H'020 Temp TXPR0 H'022 TXPR1 H'020 Data is stored into Temp instead of TXPR1. TXPR0 H'022 Longword data are stored into both TXPR1 and TXPR0 at the same time. <Longword Read Operation> <upper word read> <lower word read> 16-bit Peripheral bus 16-bit Peripheral bus consecutive access Temp TXPR1 H'020 TXPR0 H'022 TXPR0 is stored into Temp, when TXPR1 is read. Temp TXPR1 H'020 TXPR0 H'022 Temp is read instead of TXPR0. The TXPR1 controls Mailbox-31 to Mailbox-16, and the TXPR0 controls Mailbox-15 to Mailbox1. The CPU may set the TXPR bits to affect any message being considered for transmission by writing a '1' to the corresponding bit location. Writing a '0' has no effect, and TXPR cannot be cleared by writing a '0' and must be cleared by setting the corresponding TXCR bits. TXPR may be read by the CPU to determine which, if any, transmissions are pending or in progress. In effect there is a transmit pending bit for all Mailboxes except for the Mailbox-0. Writing a '1' to a bit location when the mailbox is not configured to transmit is not allowed. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1203 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network In Event Triggered Mode this module will clear a transmit pending flag after successful transmission of its corresponding message or when a transmission abort is requested successfully from the TXCR. In Time Trigger Mode, TXPR for the Mailboxes from 30 to 24 is NOT cleared after a successful transmission, in order to keep transmitting at each programmed basic cycle. The TXPR flag is not cleared if the message is not transmitted due to the CAN node losing the arbitration process or due to errors on the CAN bus, and this module automatically tries to transmit it again unless its DART bit (Disable Automatic Re-Transmission) is set in the MessageControl of the corresponding Mailbox. In such case (DART set), the transmission is cleared and notified through Mailbox Empty Interrupt Flag (IRR8) and the correspondent bit within the Abort Acknowledgement Register (ABACK). If the status of the TXPR changes, this module shall ensure that in the identifier priority scheme (MCR2 = 0), the highest priority message is always presented for transmission in an intelligent way even under circumstances such as bus arbitration losses or errors on the CAN bus. Please refer to the Application Note for details. When this module changes the state of any TXPR bit position to a '0', an empty slot interrupt (IRR8) may be generated. This indicates that either a successful or an aborted mailbox transmission has just been made. If a message transmission is successful it is signalled in the TXACK register, and if a message transmission abortion is successful it is signalled in the ABACK register. By checking these registers, the contents of the Message of the corresponding Mailbox may be modified to prepare for the next transmission. * TXPR1 Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 TXPR1[15:0] Initial value: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 R/W: R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* Note: * It is possible only to write a '1' for a Mailbox configured as transmitter.

The TXCR1 controls Mailbox-31 to Mailbox-16, and the TXCR0 controls Mailbox-15 to Mailbox-1.This register is used by the CPU to request the pending transmission requests in the TXPR to be cancelled. To clear the corresponding bit in the TXPR the CPU must write a '1' to the bit position in the TXCR. Writing a '0' has no effect. When an abort has succeeded the CAN controller clears the corresponding TXPR + TXCR bits, and sets the corresponding ABACK bit. However, once a Mailbox has started a transmission, it cannot be cancelled by this bit. In such a case, if the transmission finishes in success, the CAN controller clears the corresponding TXPR + TXCR bit, and sets the corresponding TXACK bit, however, if the transmission fails due to a bus arbitration loss or an error on the bus, the CAN controller clears the corresponding TXPR + TXCR bit, and sets the corresponding ABACK bit. If an attempt is made by the CPU to clear a mailbox transmission that is not transmit-pending it has no effect. In this case the CPU will be not able at all to set the TXCR flag. * TXCR1 Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 TXCR1[15:0] Initial value: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 R/W: R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* Note: * Only writing a `1' to a Mailbox that is requested for transmission and is configured as transmit.

(5) Data Frame Receive Pending Register (RXPR1, RXPR0) The RXPR1 and RXPR0 are 16-bit read/conditionally-write registers. The RXPR is a register that contains the received Data Frames pending flags associated with the configured Receive Mailboxes. When a CAN Data Frame is successfully stored in a receive mailbox the corresponding bit is set in the RXPR. The bit may be cleared by writing a '1' to the corresponding bit position. Writing a '0' has no effect. However, the bit may only be set if the mailbox is configured by its MBC (Mailbox Configuration) to receive Data Frames. When a RXPR bit is set, it also sets IRR1 (Data Frame Received Interrupt Flag) if its MBIMR (Mailbox Interrupt Mask Register) is not set, and the interrupt signal is generated if IMR1 is not set. Please note that these bits are only set by receiving Data Frames and not by receiving Remote frames. * RXPR1 Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 RXPR1[15:0] Initial value: R/W: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* Note : * Only when writing a '1' to clear.

The RFPR is a register that contains the received Remote Frame pending flags associated with the configured Receive Mailboxes. When a CAN Remote Frame is successfully stored in a receive mailbox the corresponding bit is set in the RFPR. The bit may be cleared by writing a '1' to the corresponding bit position. Writing a '0' has no effect. In effect there is a bit position for all mailboxes. However, the bit may only be set if the mailbox is configured by its MBC (Mailbox Configuration) to receive Remote Frames. When a RFPR bit is set, it also sets IRR2 (Remote Frame Receive Interrupt Flag) if its MBIMR (Mailbox Interrupt Mask Register) is not set, and the interrupt signal is generated if IMR2 is not set. Please note that these bits are only set by receiving Remote Frames and not by receiving Data frames. * RFPR1 Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 RFPR1[15:0] Initial value: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 R/W: R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* Note: * Only when writing a '1' to clear.

The MBIMR only prevents the setting of IRR related to the Mailbox activities, that are IRR[1] - Data Frame Received Interrupt, IRR[2] - Remote Frame Receive Interrupt, IRR[8] - Mailbox Empty Interrupt, and IRR[9] - Message OverRun/OverWrite Interrupt. If a mailbox is configured as receive, a mask at the corresponding bit position prevents the generation of a receive interrupt (IRR[1] and IRR[2] and IRR[9]) but does not prevent the setting of the corresponding bit in the RXPR or RFPR or UMSR. Similarly when a mailbox has been configured for transmission, a mask prevents the generation of an Interrupt signal and setting of an Mailbox Empty Interrupt due to successful transmission or abortion of transmission (IRR[8]), however, it does not prevent this module from clearing the corresponding TXPR/TXCR bit + setting the TXACK bit for successful transmission, and it does not prevent this module from clearing the corresponding TXPR/TXCR bit + setting the ABACK bit for abortion of the transmission.

It indicates that the Timer has overrun when working in event-trigger mode, time reference message with Next_is_Gap set has been received in time-trigger mode, and error detected on the CAN bus has occurred in test mode, respectively. Test mode has higher priority with respect to the other settings.

Its purpose is to store the number of the basic cycle for Time -Triggered Transmissions. Its value is updated in different fashions depending if this module is programmed to work as a potential time master or as a time slave. If this module is working as (potential) time master, CCR is: Incremented by one every time the cycle time (CYCTR) matches to Tx-Trigger Time of Mailbox-30 or Overwritten with the value contained in MSG_DATA_0[5:0] of Mailbox 31 when a valid reference message is received. If this module is working as a time slave, CCR is only overwritten with the value of MSG_DATA_0[5:0] of Mailbox 31 when a valid reference message is received. If CMAX = 3'111, CCR is always H'0000. * CCR (Address = H'08A) Bit: Initial value: R/W: 15 14 13 12 11 10 9 8 7 6 - - - - - - - - - - 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 5 4 3 2 1 0 0 R/W 0 R/W CCR[5:0] 0 R/W 0 R/W 0 R/W 0 R/W Page 1223 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network Bits 15 to 6: Reserved. The written value should always be '0' and the returned value is '0'. Bit 5 to 0 -- Cycle Counter Register (CCR): Indicates the number of the current Base Cycle of the matrix cycle for Timer Triggered transmission. (6) Timer Counter Register (TCNTR) This is a 16-bit read/write register that allows the CPU to monitor and modify the value of the Free Running Timer Counter. When the Timer meets TCMR0 (Timer Compare Match Register 0) + TTCR0 [6] is set to '1', the TCNTR is cleared to H'0000 and starts running again. In TimeTrigger mode, this timer can be used as Local Time and TTCR0[6] has to be cleared to work as a free running timer. Notes: 1. It is possible to write into this register only when it is enabled by the bit 15 in TTCR0. If TTCR0 bit15 = 0, TCNTR is always H'0000. 2. There could be a delay of a few clock cycles between the enabling of the timer and the moment where TCNTR starts incrementing. This is caused by the internal logic used for the pre-scaler. * TCNTR (Address = H'08C) Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 TCNTR[15:0] Initial value: R/W: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* R/W* Note: * The register can be written only when enabled in TTCR0[15]. Write operation is not allowed in Time Trigger mode (i.e. CMAX is not 3'b111). Bit 15 to 0 -- Indicate the value of the Free Running Timer. (7) Cycle Time register (CYCTR) This register is a 16-bit read-only register. This register shows Cycle Time = Local Time (TCNTR) - Reference_Mark (RFMK). In ET mode this register is the exact copy of TCNTR as RFMK is always fixed to zero. * CYCTR (Address = H'090) Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 0 R 0 R 0 R 0 R 0 R 0 R 0 R CYCTR[15:0] Initial value: R/W: 0 R Page 1224 of 3088 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (8) Section 23 Controller Area Network Reference Mark Register (RFMK) This register is a 16-bit read-only register. The purpose of this register is to capture Local Time (TCNTR) at SOF of the reference message when the message is received or transmitted successfully. In ET mode this register is not used and it is always cleared to zero. * RFMK (Address = H'094) Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 0 R 0 R 0 R 0 R 0 R 0 R 0 R RFMK[15:0] Initial value: R/W: 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R Bit 15 to 0 -- Reference Mark Register (RFMK): Indicates the value of TCNTR at SOF of time reference message. (9) Timer Compare Match Registers (TCMR0, TCMR1, TCMR2) These three registers are 16-bit read/write registers and are capable of generating interrupt signals, clearing-setting the Timer value (only supported by TCMR0) or clear the transmission messages in the queue (only supported by TCMR2). TCMR0 is compared with TCNTR, however, TCMR1 and TCMR2 are compared with CYCTR. The value used for the compare can be configured independently for each register. In order to set flags, TTCR0 bit 12-10 needs to be set. In Time-Trigger mode, TTCR0 bit6 has to be cleared by software to prevent TCNTR from being cleared. TMCR0 is for Init_Watch_Trigger, and TCMR2 is for Watch_Trigger. Interrupt: The interrupts are flagged by the Bit11, Bit15 and 14 in the IRR accordingly when a Compare Match occurs, and setting these bits can be enabled by Bit12, Bit11, Bit10 in TTCR0. The generation of interrupt signals itself can be prevented by the Bit11, Bit15 and Bit14 in the IMR. When a Compare Match occurs and the IRR11 (or IRR15 or IRR14) is set, the Bit3 or Bit2 or Bit1 in the TSR (Timer Status Register) is also set. Clearing the IRR bit also clears the corresponding bit of TSR.

TCMR1 and TCMR2 do not have this function. Cancellation of the messages in the transmission queue: The messages in the transmission queue can only be cleared by the TCMR2 through setting TXCR when a Compare Match occurs while this module is not in the halt status. TCMR1 and TCMR0 do not have this function. * TCMR0 (Address = H'098) Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W TCMR0[15:0] Initial value: R/W: 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W Bit 15 to 0 -- Timer Compare Match Register (TCMR0): Indicates the value of TCNTR when compare match occurs. * TCMR1 (Address = H'09C) Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W TCMR1[15:0] Initial value: R/W: 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W Bit 15 to 0 -- Timer Compare Match Register (TCMR1): Indicates the value of CYCTR when compare match occurs. * TCMR2 (Address = H'0A0) Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W TCMR2[15:0] Initial value: R/W: 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W 1 R/W Bit 15 to 0 -- Timer Compare Match Register (TCMR2): Indicates the value of CYCTR when compare match occurs.

The register TST[2:0] (MCR[10:8]) is used to select this module test mode. The default (initialised) settings allow this module to operate in Normal mode. The following table is examples for test modes. Test Mode can be selected only while in configuration mode. The user must then exit the configuration mode (ensuring BCR0/BCR1 is set) in order to run the selected test mode. Bit10: TST2 Bit9: TST1 Bit8: TST0 Description 0 0 0 Normal Mode (initial value) 0 0 1 Listen-Only Mode (Receive-Only Mode) 0 1 0 Self Test Mode 1 (External) 0 1 1 Self Test Mode 2 (Internal) 1 0 0 Write Error Counter 1 0 1 Error Passive Mode 1 1 0 Setting prohibited 1 1 1 Setting prohibited Normal Mode: This module operates in the normal mode. Listen-Only Mode: ISO-11898 requires this mode for baud rate detection. The Error Counters are cleared and disabled so that the TEC/REC does not increase the values, and the CTxn (n = 0 to 2) Output is disabled so that this module does not generate error frames or acknowledgment bits. IRR13 is set when a message error occurs. Self Test Mode 1: This module generates its own Acknowledge bit, and can store its own messages into a reception mailbox (if required). The CRxn/CTxn (n = 0 to 2) pins must be connected to the CAN bus. Page 1228 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network Self Test Mode 2: This module generates its own Acknowledge bit, and can store its own messages into a reception mailbox (if required). The CRxn/CTxn (n = 0 to 2) pins do not need to be connected to the CAN bus or any external devices, as the internal CTxn (n = 0 to 2) is looped back to the internal CRxn (n = 0 to 2). CTxn (n = 0 to 2) pin outputs only recessive bits and CRxn (n = 0 to 2) pin is disabled. Write Error Counter: TEC/REC can be written in this mode. This module can be forced to become an Error Passive mode by writing a value greater than 127 into the Error Counters. The value written into TEC is used to write into REC, so only the same value can be set to these registers. Similarly, this module can be forced to become an Error Warning by writing a value greater than 95 into them. This module needs to be in Halt Mode when writing into TEC/REC (MCR1 must be "1" when writing to the Error Counter). Furthermore this test mode needs to be exited prior to leaving Halt mode. Error Passive Mode: This module can be forced to enter Error Passive mode. Note: The REC will not be modified by implementing this Mode. However, once running in Error Passive Mode, the REC will increase normally should errors be received. In this Mode, this module will enter BusOff if TEC reaches 256 (Dec). However when this mode is used this module will not be able to become Error Active. Consequently, at the end of the Bus Off recovery sequence, this module will move to Error Passive and not to Error Active. When message error occurs, IRR13 is set in all test modes. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1229 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network 23.4.2 Configuration of This Module This module is considered in configuration mode or after a H/W (Power On Reset)/S/W (MCR[0]) reset or when in Halt mode. In both conditions this module cannot join the CAN Bus activity and configuration changes have no impact on the traffic on the CAN Bus. * After a Reset request The following sequence must be implemented to configure this module after (S/W or H/W) reset. After reset, all the registers are initialised, therefore, this module needs to be configured before joining the CAN bus activity. Please read the notes carefully. Reset Sequence Configuration Mode Power On/SW Reset*1 MCR[0] = 1 (automatically in hardware reset only) No GSR[3] = 0?

SW reset could be performed at any time by setting MCR[0] = 1. Mailboxes are comprised of RAMs, therefore, please initialise all the mailboxes enabled by MBC. If there is no TXPR set, RCAN-TL1 will receive the next incoming message. If there is a TXPR(s) set, RCAN-TL1 will start transmission of the message and will be arbitrated by the CAN bus. If it loses the arbitration, it will become a receiver. Timer can be started at any time after the Timer Control regs and Tx-Trigger Time are set. Figure 23.14 Reset Sequence Page 1230 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network * Halt mode When this module is in Halt mode, it cannot take part to the CAN bus activity. Consequently the user can modify all the requested registers without influencing existing traffic on the CAN Bus. It is important for this that the user waits for this module to be in halt mode before to modify the requested registers - note that the transition to Halt Mode is not always immediate (transition will occurs when the CAN Bus is idle or in intermission). After this module transit to Halt Mode, GSR4 is set. Once the configuration is completed the Halt request needs to be released. This module will join CAN Bus activity after the detection of 11 recessive bits on the CAN Bus. * Sleep mode When this module is in sleep mode the clock for the main blocks of the IP is stopped in order to reduce power consumption. Only the following user registers are clocked and can be accessed: MCR, GSR, IRR and IMR. Interrupt related to transmission (TXACK and ABACK) and reception (RXPR and RFPR) cannot be cleared when in sleep mode (as TXACK, ABACK, RXPR and RFPR are not accessible) and must to be cleared beforehand.

MCR5 can be cleared by automatically by detecting a dominant bit on the CAN Bus if MCR7 is set or by writing '0'. 2. MCR1 is cleared in SW. Clearing MCR1 and setting MCR5 have to be carried out by the same instruction. 3. MCR1 must not be cleared in SW, before GSR4 is set. MCR1 can be set automatically in HW when this module moves to Bus Off and MCR14 and MCR6 are both set. 4. When MCR5 is cleared and MCR1 is set at the same time, this module moves to Halt Request. Right after that, it moves to Halt Mode with no reception/transmission. The following table shows conditions to access registers.

As described in the previous register section, please note that IRR8 is set when one of the TXACK or ABACK bits is set, meaning one of the Mailboxes has completed its transmission or transmission abortion and is now ready to be updated for the next transmission, whereas, the GSR2 means that there is currently no transmission request made (No TXPR flags set).

One is for transmission, and the other is for reception. 1-1: When a TXPR bit(s) is set while the CAN bus is idle, the internal arbitration starts running immediately and the transmission is started. 1-2: Operations for both transmission and reception starts at SOF. Since there is no reception frame, this module becomes transmitter. 2-1: At crc delimiter, internal arbitration to search next message transmitted starts. 2-2: Operations for both transmission and reception starts at SOF. Because of a reception frame with higher priority, this module becomes receiver. Therefore, Reception is carried out instead of transmitting Frame-3. 3-1: At crc delimiter, internal arbitration to search next message transmitted starts. 3-2: Operations for both transmission and reception starts at SOF. Since a transmission frame has higher priority than reception one, this module becomes transmitter. Internal arbitration for the next transmission is also performed at the beginning of each error delimiter in case of an error is detected on the CAN Bus. It is also performed at the beginning of error delimiters following overload frame. As the arbitration for transmission is performed at CRC delimiter, in case a remote frame request is received into a Mailbox with ATX = 1 the answer can join the arbitration for transmission only at the following Bus Idle, CRC delimiter or Error Delimiter. Depending on the status of the CAN bus, following the assertion of the TXCR, the corresponding Message abortion can be handled with a delay of maximum 1 CAN Frame.

This section reports the basic procedures to use this mode. * Setting Time Trigger Mode In order to set up the time trigger mode the following settings need to be used. CMAX in CMAX_TEW must be programmed to a value different from 3'b111. Bit 15 in TTCR0 has to be set, to start TCNTR.

DART in Mailboxes used for time-triggered transmission cannot be used, since for Time Triggered Mailboxes, TXPR is not cleared to support periodic transmission. * Roles of Registers The user registers of this module can be used to handle the main functions requested by the TTCAN standard.

Change from Init_Watch_Trigger to Watch_Trigger This module offers the two registers TCMR0 and TCMR2 as H/W support for Init_Watch_Trigger and Watch_Trigger respectively. The SW is requested to enable TCMR0 and disable TCMR2 up to the first reference message is detected on the CAN Bus and then disable TCMR0 and enable TCMR2.- Schedule Synchronization state machine. Only reception of Next_is_Gap interrupt is supported. The application needs to take care of stopping all transmission at the end of the current basic cycle by setting the related TXCR flags.Master-Slave Mode control. Only automatic cycle time synchronization and CCR increment is supported. Message status count Software has to count scheduling errors for periodic messages in exclusive windows.

R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1243 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network If, at any time, a reference message cannot be detected on the CAN Bus, and the cycle time CYCTR reaches TCMR2, this module automatically aborts all pending transmissions (including the Reference Message). The following is the sequence to request further transmission in Time Triggered mode. Update data before next match of Tx-Trigger Time Idle (wait for Time-Trigger) Mailbox[x] is ready to be updated for next transmission Compare match Clear TXACK[x] No Bus Idle? TXACK[x] = 1 ? No Waiting for Interrupt No Waiting for Interrupt Yes Yes Transmission Start IRR8 = 1 ? No Arbitration on Bus End Of Frame CAN Bus Figure 23.21 Message transmission request S/W has to ensure that a message is updated before a Tx trigger for transmission occurs. When the CYCTR reaches to TTT (Tx-Trigger Time) of a Mailbox and CCR matches with the programmed cycle for transmission, this module immediately transfers the message into the Tx buffer. At this point, this module will attempt a transmission within the specified Time Enable Window. If this module misses this time slot, it will suspend the transmission request up to the next Tx Trigger, keeping the corresponding TXPR bit set to '1' if the transmission is periodic (Mailbox-24 to 30). There are three factors that may cause this module to miss the time slot - 1. The CAN bus currently used 2. An error on the CAN bus during the time triggered message transmission 3. Arbitration loss during the time triggered message transmission Page 1244 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 23 Controller Area Network In case of Merged Arbitrating Window the slot for transmission goes from the Tx_Trig of the Mailbox opening the Window (TTW = 10 bin) to the end to the TEW of the Mailbox closing the Window (TTW = 11 bin).The TXPR can be modified at any time. This module ensures the transmission of Time Triggered messages is always scheduled correctly. However, in order to guarantee the correct schedule, there are some important rules that are : TTT (Tx Trigger Time) can be modified during configuration mode. TTT cannot be set outside the range of Time_Ref, which specifies the length of basic cycle. This could cause a scheduling problem. TXPR is not automatically cleared for periodic transmission. If a periodic transmission needs to be cancelled, the corresponding TXCR bit needs to be set by the application. * Example of Time Triggered System The following diagram shows a simple example of how time trigger system works using this module in time slave mode. TTT24 CCR = 0 TTT25 Mailbox-24 (Tx) CCR = 1 TTT26 TTT27 Mailbox-24 (Tx) TTT29 Mailbox-25 to 27 (Tx) Mailbox-25 to 27 (Tx) CCR = 2 TTT28 Mailbox-28 (Tx) Mailbox-25 to 27 (Tx) Mailbox-25 to 27 (Tx) CCR = 3 Mailbox-24 (Tx) CCR = 4 Mailbox-25 to 27 (Tx) Mailbox-25 to 27 (Tx) CCR = 5 Mailbox-24 (Tx) CCR = 6 Mailbox-28 (Tx) Mailbox-25 to 27 (Tx) Mailbox-29 (Tx) Mailbox-25 to 27 (Tx) CCR = 7 time reference exclusive window merged arbitrating window exclusive window arbitrating window Figure 23.22 Example of Time trigger system as Time Slave R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1245 of 3088 SH7268 Group, SH7269 Group Section 23 Controller Area Network The following settings were used in the above example: rep_factor (register) Offset TTW[1:0] MBC[2:0] Mailbox-24 3'b001 6'b000000 2'b00 3'b000 Mailbox-25 3'b000 6'b000000 2'b10 3'b000 Mailbox-26 3'b000 6'b000000 2'b10 3'b000 Mailbox-27 3'b000 6'b000000 2'b11 3'b000 Mailbox-28 3'b010 6'b000001 2'b00 3'b000 Mailbox-29 3'b011 6'b000110 2'b01 3'b000 Mailbox-30 3'b111 Mailbox-31 3'b011 CMAX = 3'b011, TXPR[30] = 0 During merged arbitrating window, request by time-triggered transmission is served in the way of FCFS (First Come First Served). For example, if Mailbox-25 cannot be transmitted between TxTrigger Time 25 (TTT25) and TTT26, Mailbox-25 has higher priority than Mailbox-26 between TTT26 and 28. MBC needs to be set into 3'b111, in order to disable time-triggered transmission. If this module is Time Master, MBC[30] has to be 3'b000 and time reference window is automatically recognized as arbitrating window. * Timer Operation Figure 23.23 shows the timing diagram of the timer. By setting Tx-Trigger Time = n, time trigger transmission starts between CYCTR = n + 2 and CYCTR = n + 3.

For example, If transmission of Mailbox-25 is completed and CYCTR doesn't reach TTT26, event-trigger transmission starts based on message transmission priority specified by MCR2. TXPR of time-triggered transmission is not cleared after transmission completion, however, that of event-triggered transmission is cleared. Note: that in the case that the TXPR is not set for the Mailbox which is assigned to close the Merged Arbitrating Window (MAW), then the MAW will still be closed (at the end of the TEW following the TTT of the assigned Mailbox.

Only if CPU clears RXPR[N]/RFPR[N] at the same time that UMSR is set in overrun, RXPR[N]/RFPR[N] may be set again even though the message has not been updated. TimeStamp may also be updated, however it can be read properly before clearing RXPR[N]/RFPR[N]. 2. In case overwrite configuration (NMC = 1) is used for the Mailbox N the message must be discarded when UMSR[N] = 1, UMSR[N] cleared and the full Interrupt Service Routine started again. In case of overrun configuration (NMC = 0) is used clear again RXPR[N]/RFPR[N]/ UMSR[N] when UMSR[N] = 1 and consider the message obsolate. Figure 23.24 Message receive sequence R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1249 of 3088 Section 23 Controller Area Network SH7268 Group, SH7269 Group When this module recognises the end of the Arbitration field while receiving a message, it starts comparing the received identifier to the identifiers set in the Mailboxes, starting from Mailbox-31 down to Mailbox-0. It first checks the MBC if it is configured as a receive box, and reads LAFM, and reads the CAN-ID of Mailbox-31 (if configured as receive) to finally compare them to the received ID. If it does not match, the same check takes place at Mailbox-30 (if configured as receive). Once this module finds a matching identifier, it stores the number of Mailbox-[N] into an internal buffer, stops the search, and goes back to idle state, waiting for the EndOfFrame (EOF) to th come. When the 6 bit of EOF is notified by the CAN Interface logic, the received message is written or abandoned, depending on the NMC bit. No modification of configuration during communication is allowed. Entering Halt Mode is one of ways to modify configuration. If it is written into the corresponding Mailbox, including the CAN-ID, i.e., there is a possibility that the CAN-ID is overwritten by a different CAN-ID of the received message due to the LAFM used. This also implies that, if the identifier of a received message matches to ID + LAFM of 2 or more Mailboxes, the higher numbered Mailbox will always store the relevant messages and the lower numbered Mailbox will never receive messages. Therefore, the settings of the identifiers and LAFMs need to be carefully selected. With regards to the reception of data and remote frames described in the above flow diagram the clearing of the UMSR flag after the reading of IRR is to detect situations where a message is overwritten by a new incoming message stored in the same mailbox (if its NMC = 1) while the interrupt service routine is running. If during the final check of UMSR a overwrite condition is detected the message needs to be discarded and read again. In case UMSR is set and the Mailbox is configured for overrun (NMC = 0) the message is still valid, however it is obsolete as it is not reflecting the latest message monitored on the CAN Bus. Please access the full Mailbox content before clearing the related RXPR/RFPR flag. Please note that in the case a received remote frame is overwritten by a data frame, both the remote frame receive interrupt (IRR2) and data frame received interrupt (IRR1) and also the Receive Flags (RXPR and RFPR) are set. In an analogous way, the overwriting of a data frame by a remote frame, leads to setting both IRR2 and IRR1. When a message is received and stored into a Mailbox all the fields of the data not received are stored as zero. The same applies when a standard frame is received. The extended identifier part (EXTID[17:0]) is written as zero.

Change of ID, RTR, IDE, LAFM, Data, DLC, NMC, ATX, DART This change is possible only when MBC = 3'b000. Confirm that the corresponding TXPR is not set. The configuration (except MBC bit) can be changed at any time. Change from transmit to receive configuration (MBC) Confirm that the corresponding TXPR is not set. The configuration can be changed only in Halt or reset state. Please note that it might take longer for this module to transit to halt state if it is receiving or transmitting a message (as the transition to the halt state is delayed until the end of the reception/transmission), and also this module will not be able to receive/transmit messages during the Halt state. In case this module is in the Bus Off state the transition to halt state depends on the configuration of the bit 6 of MCR and also bit and 14 of MCR. * Change configuration (ID, RTR, IDE, LAFM, Data, DLC, NMC, ATX, DART, MBC) of receiver box or Change receiver box to transmitter box The configuration can be changed only in Halt Mode. This module will not lose a message if the message is currently on the CAN bus and this module is a receiver. This module will be moving into Halt Mode after completing the current reception. Please note that it might take longer if this module is receiving or transmitting a message (as the transition to the halt state is delayed until the end of the reception/transmission), and also this module will not be able to receive/transmit messages during the Halt Mode. In case this module is in the Bus Off state the transition to halt mode depends on the configuration of the bit 6 and 14 of MCR.

No ACK error is detected even when any other nodes are not connected to the CAN bus. This occurs when channel 1 transmits an ACK in the ACK field in response to a message channel 0 has transmitted. Channel 1 receives a message which channel 0 has transmitted on the CAN bus and then transmits an ACK in the ACK field. After that, channel 0 receives the ACK. To avoid this, make channel 1 which is not currently used for transmission the listen-only mode (TST[2:0] = B'001) or the reset state (MCR0 = 1). With this setting, only a channel which transmits a message transmits an ACK. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1259 of 3088 Section 23 Controller Area Network SH7268 Group, SH7269 Group 2. Internal arbitration for channels 0 and 1 is independently controlled to determine the order of transmission. Although the internal arbitration is performed on 31 Mailboxes at a time, it is not performed on 64 Mailboxes at a time even though multiple channels function as a single channel. 3. Do not set the same transmission message ID in both channels 0 and 1. Two messages may be transmitted from the two channels after arbitration on the CAN bus.

This operation is called arbitration. In arbitration, when multiple units start transferring simultaneously, the bus mastership is given to one unit among them. Only one unit can obtain bus mastership through arbitration, so the following priority for bus mastership is determined. (a) Priority according to communications type Broadcast communications (one-to-many communications) has priority over normal communications (one-to-one communications). (b) Priority according to master address The unit with the smallest master address has priority among units of the same communications type. Example: The master address is configured with 12 bits. A unit with H'000 has the highest priority, while a unit with H'FFF has the lowest priority. Note: When a unit loses in arbitration, the unit can automatically enter retransfer mode (0 to 7 retransfer times can be selected by the RN bit in IEMCR).

Table 24.2 shows the transfer speed in each communications mode and the maximum number of transfer bytes in one communications frame.

Note that correct communications is not guaranteed if the master and slave units do not adopt the same communications mode. In the case of communications between a unit with IEB = 6 MHz and a unit with IEB = 6.29 MHz, correct communications are not possible even if the same communications mode is adopted.

Oscillation frequency when this LSI is used Communications Address In the IEBus, a specific 12-bit communications address is allocated to each individual unit. A communications address is configured as follows. * Upper four bits: group number (number identifying a group to which the unit belongs) * Lower eight bits: unit number (number identifying individual units in a group) R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1265 of 3088 Section 24 IEBusTM Controller (4) SH7268 Group, SH7269 Group Broadcast Communications In normal transfer, a single master unit communicates with a single slave unit, so one-to-one transfer or reception takes place. In broadcast communications, a single master unit communicates with multiple slave units. Since there are multiple slave units, no acknowledgements are returned from the slave units during communications. A broadcast bit decides whether broadcast or normal communications is done. (For details of the broadcast bit, see section 24.1.2 (1) (b), Broadcast Bit. There are two types of broadcast communications. (a) Group broadcast communications Broadcast communications is aimed at units with the same group number, meaning that those units have the same upper four bits of the communications address. (b) General broadcast communications Broadcast communications is aimed at all units regardless of group number. Group broadcast and general broadcast communications are identified by a slave address. (For details on the slave address, see section 24.1.2 (3), Slave Address Field.) Page 1266 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Section 24 IEBusTM Controller SH7268 Group, SH7269 Group 24.1.2 Communications Protocol Figure 24.1 shows an IEBus transfer signal format. Communications data is transferred as a series of signals referred to as a communications frame. The number of data, which can be transmitted in a single communications frame and the transfer speed, differs according to the communications mode. (When IEB = 12, 18, 24, 30, or 36 MHz) Field name Number of bits Header 1 Master address field 1 12 Start Broad- Master bit cast address bit 1 P Slave address field 12 1 1 Control field Slave address Control bits P A 4 1 1 P A Message length field 8 1 1 Message length bits P A Data field 8 1 Data bits 1 P A 8 Data bits 1 1 P A Transfer time Mode 0 Approximately 7330 s Approximately 1590 x N s Mode 1 Approximately 2090 s Approximately 410 x N s Mode 2 Approximately 1590 s Approximately 300 x N s P: Parity bit (1 bit) A: Acknowledge bit (1 bit) When A = 0: ACK When A = 1: NAK N: Number of bytes Note: The value of acknowledge bit is ignored in broadcast communications. Figure 24.1 Transfer Signal Format (1) Header A header is comprised of a start bit and a broadcast bit. (a) Start Bit The start bit is a signal to inform other units of the start of data transfer. A unit attempting to start data transfer outputs a low-level signal (the start bit) for a specified period and then outputs the broadcast bit. If another unit is already outputting a start bit when a unit attempts to output a start bit, the unit waits for completion of the start bit from the other unit without outputting its own start bit, and then outputs the broadcast bit synchronized with the completion timing. Other units enter the receive state after detecting the start bit. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1267 of 3088 Section 24 IEBusTM Controller (b) SH7268 Group, SH7269 Group Broadcast Bit The broadcast bit is a bit to identify the type of communications: broadcast or normal. When this bit is cleared to 0, it indicates broadcast communications. When it is set to 1, it indicates normal communications. Broadcast communications includes group broadcast and general broadcast, which are identified by a value of the slave address. (For details of the slave address, see section 24.1.2 (3), Slave Address Field.) Since multiple slave units are communications destination units, in the case of broadcast communications, the acknowledge bit is not returned from each field described in (2) and below. When more than one unit starts to transfer a communications frame with the same timing, broadcast communications has priority over normal communications, and arbitration occurs. (2) Master Address Field The master address field is a field for transmitting the unit address (master address) to other units. The master address field is comprised of master address bits and a parity bit. The master address consists of 12 bits and the MSB is output first. When more than one unit start to transfer broadcast bits having the same value with the same timing, arbitration is decided by the master address field. In the master address field, self-output data and data on the bus are compared for every one-bit transfer. If the self-output master address and data on the bus are different, the unit that loses arbitration will stop its transfer and enter the receive state. Since the IEBus is configured with wired AND, the unit having the smallest master address of the units in arbitration (arbitration master) wins in arbitration. Finally, only a single unit remains in the transfer state as a master unit after outputting a 12-bit master address. Next, this master unit outputs a parity bit*, defines the master address for other units, and then enters the slave address field output state. Note: * Since even parity is used, when the number of one bit in the master address is odd, the parity bit is 1. Page 1268 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (3) Section 24 IEBusTM Controller Slave Address Field The slave address field is a field to transmit an address (the slave address) of a unit (the slave unit) to be transmitted. The slave address field is comprised of slave address bits, a parity bit, and an acknowledge bit. The slave address consists of 12 bits and the MSB is output first. The parity bit is output after the 12-bit slave address is transmitted to avoid receiving the slave address accidentally. The master unit then detects the acknowledgement from the slave unit to confirm that the slave unit exists on the bus. When the acknowledgement is detected, the master unit enters the control field output state. However, the master unit enters the control field output state without detecting the acknowledgement in broadcast communications. The slave unit returns an acknowledgement when the slave addresses match and the parities of the master and slave addresses are correct. When the parity of either the master or slave address is incorrect, the slave unit decides that the master or slave address was not correctly received and does not return the acknowledgement. In this case, the master unit enters the waiting (monitor) state and communications ends. In the case of broadcast communications, the slave address is used to identify the type of broadcast communications (group or general) as follows: * When the slave address is H'FFF: General broadcast communications * When the slave address is other than H'FFF: Group broadcast communications Note: The group number is the upper 4-bit value of the slave address in group broadcast communications. (4) Control Field The control field is a field for transmitting the type and direction of the following data field. The control field is comprised of control bits, a parity bit, and an acknowledge bit. The control bits consist of four bits and the MSB is output first. The parity bit is output following the control bits. When the parity is correct, and the slave unit can implement the function required from the master unit, the slave unit returns an acknowledgement and enters the message length field output state. However, if the slave unit cannot implement the requirements from the master unit even though the parity is correct, or if the parity is not correct, the slave unit does not return an acknowledgement and returns to the waiting (monitor) state. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1269 of 3088 Section 24 IEBusTM Controller SH7268 Group, SH7269 Group The master unit enters the subsequent message length field output state after confirming the acknowledgement. When the acknowledgement is not confirmed, the master unit enters the waiting (monitor) state, and communications ends. However, in the case of broadcast communications, the master unit enters the following message length field output state without confirming the acknowledgement. For details of the contents of the control bit, see table 24.4. (5) Message Length Field The message length field is a field for specifying the number of transfer bytes. The message length field is comprised of message length bits, a parity bit, and an acknowledge bit. The message length has eight bits and the MSB is output first. Table 24.3 shows the number of transfer bytes. Table 24.3 Contents of Message Length bits Message Length bits (Hexadecimal) Number of Transfer Bytes H'01 1 byte H'02 2 bytes : : H'FF 255 bytes H'00 256 bytes Note: If a number greater than the maximum number of transfer bytes in one frame is specified, communications are done in multiple frames depending on the communications mode. In this case, the message length bits indicate the number of remaining communications data after the first transfer. In this LSI, the message length bits must be smaller than the maximum number of transfer bytes in one frame. Set these within the ranges shown below. Mode 0: 1 to 16 bytes Mode 1: 1 to 32 bytes Mode 2: 1 to 128 bytes This field operation differs depending on the value of bit 3 in the control field: master transmission (the bit 3 of the control bits is 1) or master reception (the bit 3 of the control bits is 0). Page 1270 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (a) Section 24 IEBusTM Controller Master Transmission The master unit outputs the message length bits and the parity bit. When the parity is even, the slave unit returns an acknowledgement and enters the following data field. Note that the slave unit does not return an acknowledgement in broadcast communications. When the parity is odd, the slave unit decides that the message length field is not correctly received, does not return an acknowledgement, and returns to the waiting (monitor) state. In this case, the master unit also returns to the waiting state and communications end. (b) Master Reception The slave unit outputs the message length bits and parity bit. When even parity is confirmed, the master unit returns an acknowledgement. When the parity is not correct, the master unit decides that the message length bits are not correctly received, does not return an acknowledgement, and returns to the waiting state. In this case, the slave unit also returns to the waiting state and communications end. (6) Data Field The data field is a field for data transmission/reception to and from the slave unit. The master unit transmits/receives data to and from the slave unit using the data field. The data field is comprised of data bits, a parity bit, and an acknowledge bit. The data bits consist of eight bits and the MSB is output first. The parity and acknowledge bits are output following the data bits from the master unit and slave unit, respectively. Broadcast communications are performed only for the transmission of the master unit. In this case, the acknowledge bit is ignored. Operations in master transmission and master reception are described below. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1271 of 3088 Section 24 IEBusTM Controller (a) SH7268 Group, SH7269 Group Master Transmission The master unit transmits the data bits and parity bit to the slave unit to write data from the master unit to the slave unit. The slave unit receives the data bits and parity bit, and returns an acknowledgement if the parity bit is even and the receive buffer is empty. If the parity bit is odd or the receive buffer is not empty, the slave unit does not accept the corresponding data and does not return an acknowledgement. When the slave unit does not return an acknowledgement, the master unit retransmits the data. This operation is repeated until either an acknowledgement from the slave unit is detected or the maximum number of data transfer bytes is reached. When the parity is even and the acknowledgement is output from the slave unit, the master unit transmits the subsequent data if data remains and the maximum number of transfer bytes is not exceeded. In the case of broadcast communications, the slave unit does not return the acknowledgement, and the master unit transfers data byte by byte. (b) Master Reception The master unit outputs synchronous signals corresponding to all data bits to be read from the slave unit. The slave unit outputs the data bits and parity bit on the bus in accordance with the synchronous signals from the master unit. The master unit reads the parity bit output from the slave unit, and checks the parity. If the parity is not even, or the receive buffer is not empty, the master unit rejects acceptance of the data, and does not return the acknowledgement. The master unit reads the same data repeatedly if the number of data does not exceed the maximum number of transfer bytes in one frame. If the parity is even and the receive buffer is empty, the master unit accepts data and returns an acknowledgement. The master unit reads in the subsequent data if the number of data does not exceed the maximum number of transfer bytes in one frame.

The parity bit is added to respective data of the master address, slave address, control, message length, and data bits. Even parity is used. When the number of bits having the value 1 is odd, the parity bit is 1. When the number of bits having the value 1 is even, the parity bit is 0. (8) Acknowledge bit In normal communications (single unit to single unit communications), the acknowledge bit is added in the following positions to confirm that data is correctly accepted. * At the end of the slave address field * At the end of the control field * At the end of the message length field * At the end of the data field The acknowledge bit is defined below. * 0: indicates that the transfer data is acknowledged. (ACK) * 1: indicates that the transfer data is not acknowledged. (NAK) Note that the acknowledge bit is ignored in the case of broadcast communications. (a) Acknowledge bit at the End of the Slave Address Field The acknowledge bit at the end of the slave address field becomes NAK in the following cases and transfer is stopped. * When the parity of the master address or slave address bits is incorrect * When a timing error (an error in bit format) occurs * When there is no slave unit R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1273 of 3088 Section 24 IEBusTM Controller (b) SH7268 Group, SH7269 Group Acknowledge bit at the End of the Control Field The acknowledge bit at the end of the control field becomes NAK in the following cases and transfer is stopped. * When the parity of the control bits is incorrect * When the bit 3 of the control bits is 1 (data write) although the slave receive buffer* is not empty * When the control bits are set to data read (H'3, H'7) although the slave transmit buffer* is empty * When another unit which locked the slave unit requests H'3, H'6, H'7, H'A, H'B, H'E, or H'F in the control bits although the slave unit has been locked * When the control bits are the locked address read (H'4, H'5) although the unit is not locked * When a timing error occurs * When the control bits are undefined Note: See section 24.1.3 (1), Slave Status Read (Control Bits: H'0, H'6). (c) Acknowledge Bit at the End of the Message Length Field The acknowledge bit at the end of the message length field becomes NAK in the following cases and transfer is stopped. * When the parity of the message length bits is incorrect * When a timing error occurs (d) Acknowledge Bit at the End of the Data Field The acknowledge bit at the end of the data field becomes NAK in the following cases and transfer is stopped. * When the parity of the data bits is incorrect* * When a timing error occurs after the previous transfer of the acknowledge bit * When the receive buffer becomes full and cannot accept further data* Note: * In this case, the data field is transferred repeatedly until the number of data reaches the maximum number of transfer bytes if the number of data does not exceed the maximum number of transfer bytes in one frame.

Since this LSI can support up to mode 2, bits 6 and 7 are fixed to 10. 2. The value of bit 4 can be selected by the STE bit in the IEBus master unit address register 1 (IEAR1). 3. The slave receive buffer is a buffer which is accessed during data write (control bits: H'A, H'B, H'E, H'F). In this LSI, the slave receive buffer corresponds to the IEBus receive buffer register (IERB001 to IERB128); and bit 1 is the value of the RXBSY bit in the IEBus receive status register (IERSR). 4. The slave transmit buffer is a buffer which is accessed during data read (control bits: H'3, H'7). In this LSI, the slave transmit buffer corresponds to the IEBus transmit buffer register (IETB001 to IETB128) and bit 0 is the value of the SRQ bit in the IEBus general flag registers (IEFLG).

In the case of data write (H'B or H'F) or command write (H'A or H'E), data received in the slave unit is processed in accordance with the operation specification of the slave unit. Notes: 1. The user can select data and commands freely in accordance with the system. 2. H'3, H'A, or H'B may lock depending on the communications condition and status. (3) Locked Address Read (Control Bits: H'4, H'5) In the case of the locked address read (H'4 or H'5), the address (12 bits) of the master unit, which issues the lock instruction, is configured in bytes as shown in figure 24.3. MSB LSB Control bits: H'4 Control bits: H'5 Lower 8 bits Undefined Upper 4 bits Figure 24.3 Locked Address Configuration (4) Locking/Unlocking (Control Bits: Setting (H'3, H'A, H'B), Cancellation: (H'6)) The lock function is used for message transfer over multiple communications frames. A locked unit receives data only from the unit which locked it. Locking and unlocking are described below. (a) Locking When an acknowledge bit of 0 in the message length field is transmitted/received with the control bits (H'3, H'A, H'B) indicating the lock operation, and then the communications frame is completed before completion of data transmission/reception for the number of bytes specified by the message length bits, the slave unit is locked by the master unit. In this case, the bit (bit 2) relevant to locking in the byte data indicating the slave status is set to 1. Lock is set only when the number of data exceeds the maximum number of transfer bytes in one frame. Lock is not set by other error terminations. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1277 of 3088 Section 24 IEBusTM Controller (b) SH7268 Group, SH7269 Group Unlocking When the control bits indicate the lock (H'3, H'A, or H'B) or unlock (H'6) operation and the byte data for the number of bytes specified by the message length bits are transmitted/received in a single communications frame, the slave unit is unlocked by the master unit. In this case, the bit (bit 2) relevant to locking in the byte indicating the slave status is cleared to 0. Note that locking and unlocking are not done in broadcast communications. Note: * There are three ways to cause a locked unit to unlock itself. * Perform a power-on reset * Put the unit in deep standby mode * Issue an unlock command through the IEBus command register (IECMR) Note that the LCK flag in IEFLG can be used to check whether the unit is locked or unlocked. 24.1.4 Bit Format Figure 24.4 shows the bit format (conceptual diagram) configuring the IEBus communications frame. Logic 1 Logic 0 Preparation period Synchronous period Data period Halt period Active low: Logic 1 = low level and logic 0 = high level Active high: Logic 1 = high level and logic 0 = low level Figure 24.4 IEBus Bit Format (Conceptual Diagram) Each period of the bit format for use of active high signals is described below. * Preparation period: first logic 1 period (high level) * Synchronous period: subsequent logic 0 period (low level) * Data period: period indicating bit value (logic 1: high level, logic 0: low level) * Halt period: last logic 1 period (high level) Page 1278 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Section 24 IEBusTM Controller SH7268 Group, SH7269 Group For use of active low signals, levels are reversed from the active high signals. The synchronous and data periods have approximately the same length. The IEBus is synchronized bit by bit. The specifications for the time of all bits and the periods allocated to the bits differ depending on the type of transfer bits and the unit (master or slave unit). 24.1.5 Configuration Figure 24.5 shows the entire block configuration and table 24.6 lists the functions of each block.

While this bit is 0, a reception error interrupt does not occur when the receive buffer is not in the receive enabled state, and the reception stops and enters the wait state. The master address is not saved. 0: A broadcast receive error is not generated up to the control field. 1: A broadcast receive error is generated up to the control field.

This module sets this flag when this module receives the next byte data while the receive data has not been read (the RXBSY flag is not cleared). If this case, this module assumes that an overrun error has occurred and returns a NAK to the communications destination unit. The communications destination unit retransmits data up to the maximum number of transmit bytes. This module, however, returns a NAK when the RXBSY flag remains set. If the RXBSY flag is cleared to 0, this module returns an ACK, and receives the next data. In broadcast reception, if the RXBSY flag is set during data receive start, this module immediately enters the wait state. This flag becomes enabled only after the receive start flag (RXS) is set.

If a parity error occurs before data field reception, this module immediately enters the wait state and the RXEPE flag is not set. If a parity error occurs when the maximum number of receive bytes in one frame have not been received, the RXEPE flag is not set yet. When a parity error occurs, this module returns a NAK to the communications destination unit via the acknowledge bit. In this case, the communications destination unit continues retransfer up to the maximum number of receive bytes in one frame and if the reception has been completed normally by clearing the parity error, the RXEPE flag is not set. If the parity error is not cleared when the reception is terminated before receiving data for the number of bytes specified by the message length, the RXEPE flag is set. In broadcast reception, if a parity error occurs during data field reception, this module enters the wait state immediately after setting the RXEPE flag. This flag is enabled only after the receive start flag (RXS) is set. If this error occurs before the receive start flag is set, this module stops communication and enters the wait state.

Each source also has status flags corresponding to the IEBus transmit status register (IETSR) and IEBus receive status register (IERSR). Reading the status flags allows determination of the interrupt sources.

At this time, transfer proceeds until the (n + 1)th byte has been transmitted, where n is the maximum number of transfer bytes. Then, when NAK is received via the acknowledge bit of the (n + 1)th byte, the TXERO flag is set. If ACK is received rather than NAK, the TXF flag is set. Figure 24.18 shows the timing of operations when the maximum number of transfer bytes is reached but transmission has not been completed.

Thus, when data of the (n + 1)th byte cannot be received, the receive timing error is detected and the RXERTME flag is set. At this time, the RXEDLE flag is not set. The RXEDLE flag is set when the (n + 1)th byte is received. In the same way, when the maximum number of transfer bytes has been received and a parity error has not been cleared, and the (n + 1)th byte cannot be received, the RXERTME flag is set. At this time, the RXEPE flag is not set. The RXEPE flag is set when the (n + 1)th byte is received.

Figure 25.3 shows the subframe format. According to this format, the Renesas SPDIF performs biphase-mark modulation (channel coding) that will make the transmission line's DC component a minimum value. 0 3 4 L Synchronization S Aux preamble B B/M/W 7 8 27 28 L S B M S B Audio sample word V 31 U C P V = Validity flag U = User data C = Channel status P = Parity bit Figure 25.3 Subframe Format R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1331 of 3088 SH7268 Group, SH7269 Group Section 25 Renesas SPDIF Interface Figure 25.4 shows the block format, which consists of 192 continuous frames. One block begins at the starting frame (preamble B) and ends at the 192nd frame (frame 191), and the preamble is used to identify all subframes. Each block has a total of 384 subframes, which are classified into three categories: subframe 0 indicating the beginning of a new block, subframe 1 (usually the channel 1), and subframe 2 (usually the channel 2). Usually, the music data sent and received by the SPDIF is continuous so that continuous blocks appear. 0 B 1 Channel 1 W Channel 2 M 191 Channel 1 M 0 Channel 1 W Channel 2 B 1 Channel 1 W Channel 2 M Channel 1 B = Start of block preamble W = Channel 2 preamble M = Channel 1 preamble but not start of block Figure 25.4 Block Format Table 25.2 shows the binary values of the Renesas SPDIF preambles. The polarity of these preambles differs depending on the status of the preceding symbol (parity bit). Table 25.2 Binary Preamble Values Preamble Preceding Symbol's Status = 0 Preceding Symbol's Status = 1 B 11101000 00010111 M 11100010 00011101 W 11100100 00011011 Note: As shown in figure 25.3, the even parity bit at time slot 31 of a subframe determines the type of a preamble for one cycle of transmission. Usually, therefore, any one is selected from the set states that are sent through the Renesas SPDIF. However, IEC60958 requires decoding both types in view of connection with the preamble polarity reversed; the Renesas SPDIF has preambles decoded according to table 25.2. Channel status information is encoded at the rate of one bit per subframe, making the channel status information per block have a total of 192 bits for each of subframes 1 and 2. For the format of the channel status, refer to the IEC 60958 standard.

The clock for the transmitter module is an oversampling clock supplied from the outside. This clock usually selects a value that serves as an oversample at a frequency eight times larger than the clock frequency required for biphase-mark encoding. In this case, the clock frequency required to transmit 32 time slots in a subframe is 512 times as large as the sample frequency for audio data. Audio data and channel status information are first written into the module's channel 1 and then into channel 2. Generally, the channel status need to be written only when the information changes. The SPDIF module requests that the channel status be written in 30 frames -- when all the current channel status data have been transmitted. You need to write somewhere between frame 31 and the beginning of the next block of 192 frames. The audio data is stored in a double buffer arrangement. To make sure that the first stage buffer is empty, you can send an interrupt request or poll the status register. DMA transfers send channel 1 audio data on the first request and channel 2 data on the second. The channel status information is stored in the 30-bit registers of channels 1 and 2. For each channel, the channel status information per frame consists of 192 bits. Because necessary data covers only 30 bits, zeros continue to be sent after the transmission of the first 30 bits until the block is completed. User data forms a 32-bit double buffer arrangement. You can make sure that the first stage buffer is empty by either sending an interrupt request or polling the status register. Usually, information about the user data will become insufficient with the length of data between blocks. Transmission takes place in a sequence of channels 1 and 2. For the user data within a block, 384 bits are transmitted before the next block is continuously transmitted. The audio data handled by the Renesas SPDIF module is a linear PCM, making it possible to set up to 24 bits. For this reason, the V flag indicating that audio data is a linear PCM remains to be 0. The V flag involves no register-based setting. An even parity is created for each 32 bits of serial output data (excluding the preamble). Note: When transmitter user buffer underrun occurs, the current data in the buffer data of SPDIF is transmitted until the next data is filled. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1359 of 3088 Section 25 Renesas SPDIF Interface 25.8.2 SH7268 Group, SH7269 Group Transmitter Module Initialization The device defaults to an idle state when it comes out of reset, or can be put into an idle state when 0 is written to the TME bit in the CTRL register. When the transmitter module is idle, it has the following settings: * The transmitter idle status bit (TIS) is set to 1, all other status bits are cleared to 0. * Preamble generation is invalid. * Synchronization between channels 1 and 2 is set to 0 (0 for channel 1, 1 for channel 2). * Both word_count and frame_count are set to 0. * The output from the biphase-mark encoder is set to 0. Channel status, user and audio data registers will retain its value prior to putting the module into idle. To exit the idle state the user must write 1 to the TME bit in the CTRL register. 25.8.3 Initial Settings for Transmitter Module When the TME bit is set to 1, the TUIR and CSTX bits are set to 1. After that, if data is written in the order of 1) TUI and 2) TLCS and TRCS, a channel status error will occur. To avoid this, be sure to write data in the order of 1) TLCS and TRCS and 2) TUI. Before writing the first audio data (write access to TLCA or TRCA by the CPU or write access to TDAD by the DMA transfer) after setting the TME bit to 1, be sure to check that the CSTX and TUIR bits are cleared by writing to TLCS, TRCS, and TUI.

Data transfer timing can be achieved in three ways. Either the transfer is done by interrupts, DMA requests or by polling the status register. There is a shared interrupt line (for both transmit and receive) and a single transmitter DMA request line. Figure 25.5 shows a data transfer with an interrupt for the transmitter. Start Idle Set control bit enabled (TCBI) Wait for interrupt Load left or right audio channel data Enter idle state? No Yes Set control bit disabled (TCBI) Figure 25.5 Transmitter Data Transfer Flow Diagram - Interrupt Driven R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1361 of 3088 SH7268 Group, SH7269 Group Section 25 Renesas SPDIF Interface Figure 25.6 shows a data transfer with a DMA transfer for the transmitter. Start Idle Wait for transmitter DMA request Load left or right audio channel data Yes Enter idle state? No Figure 25.6 Transmitter Data Transfer Flow Diagram--DMA Request Driven Channel status information is required to be updated when the information has changed. Because the updating needs to be done before the transmission of the next block, the channel status to be updated should be written after 30 frames have been sent; this is indicated either by an interrupt or by polling the status bit. If channel status is written before 30 frames have been sent (while current information is being sent) then an interrupt indicates that the channel status error bit (CSE) in the status register has been set.

The encoded data, shown in linear PCM format, is stored into the audio data register. The register also stores the channel status and user information being received simultaneously as auxiliary information. The main clock for the receiver module is an oversampling clock supplied from the outside. The module operates at a frequency four times as large as the oversampling clock. Note: The oversampling clock is the same for the transmitter and receiver. Clock recovery is performed using a pulse width counter and averaging filters to produce a sampling pulse in the middle of each bit in the datastream. A clock error status bit indicates clock synchronization loss. Synchronization is achieved when a preamble occurs on the data stream for the first time. Continuous adjustment prevents jitter and/or clock drift from affecting clock recovery, provided that they fall within the clock recovery specifications. Once the clock recovery is successful the biphase-mark decoder initiates its preamble detection. The decoder searches for the start of block preamble (see table 25.2). A preamble error status bit indicates that following preambles have not appeared at the correct time, such failures are most likely caused by transmission loss or interference. Even parity checking is performed on the decoded data. A discrepancy will result in the parity error status bit being set. The SPDIF module acquires user data and channel status information in addition to audio data. The audio is stored in a double buffer arrangement. Either an interrupt request because of a full buffer or polling of the status bit will indicate when the data is ready to be read. DMA transfers receive channel 1 audio data on the first request and channel 2 data on the second. Channel status is stored in a 30-bit register. Channel status information is received at 1-bit per subframe. Therefore the registers will not be full until a total of 30 frames for each channel have been received. New channel status is compared with the current data to see if it has changed and is only read by the processor if it has. User data, which is also received at the same time, is stored into the register on a subframe basis, so that the reception is completed when 16 frames are reached. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1363 of 3088 Section 25 Renesas SPDIF Interface SH7268 Group, SH7269 Group Notes: 1. Channel status data requests do not support DMA. 2. When receiver user buffer overrun occurs, the current data in the buffer data of SPDIF is overwritten by the next incoming data from SPDIF interface. 25.9.2 Receiver Module Initialization The device defaults to an idle state when it comes out of reset, or can be put into an idle state by writing 0 to bit RME in the CTRL register. Whilst idle the module has the following settings: * The receiver idle status bit is set to 1, all other status bits are cleared to 0. * Synchronization between channels 1 and 2 is set to 0 (0 for channel 1, 1 for channel 2). * Both Word_count and frame_count are set to 0. Channel status registers, user data registers and audio data registers will retain its value prior to putting the module into idle. To exit the idle state the user must write 1 to the bit RME in the CTRL register. 25.9.3 Receiver Module Data Transfer Once the module has left the idle state it is ready for data transfer. Data transfer timing can be achieved in three ways. The transfer can be done by interrupts, or by polling the status register, or by DMA. There is a shared interrupt line (transmit and receive) and a single receiver DMA request line. Data transfer for the receiver can be interrupted by error signals caused by: 1. Clock recovery failure. 2. Transmission loss or interference - indicated by a preamble error. 3. Parity check failure. Transmission loss or interference can cause the start of subframe or start of block preamble to be misplaced or not present. Parity check failure occurs when the parity bit is incorrect, this can be caused by any of the above. * Clock Recovery Deviation The receive margin for clock recovery is based on the following equation: M= Page 1364 of 3088 0.5 - 1 D - 0.5 - (L - 0.5) F - (1 + F) x 100% 2N N R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group where Section 25 Renesas SPDIF Interface M = receive margin N = oversampling rate L = frame length = 33 D = duty cycle = 0.6 -6 F = oversampling clock deviation = Level II accuracy = 1000 in 10e Figure 25.7 indicates what the receive margin M represents Internal Clock Data M Sampling Clock Figure 25.7 Receive Margin Introducing jitter into the equation gives the following inequality. j 0.5 - 1 D - 0.5 - (L - 0.5) F - (1 + F) x 100% 2N N J = clock jitter Eight times oversampling produces a receive margin = 39.25% Four times oversampling produces a receive margin = 31.75% Two times oversampling produces a receive margin = 16.75% The fastest sample frequency is 48 kHz. This requires a clock speed of 128 x 48 kHz = 6.144 MHz. The worst case jitter in one cycle is specified at 40 ns = 24.5% of the period. This means that an oversampling rate of 4 or more will satisfy the inequality and therefore be sufficient for clock recovery.

The idle state can be detected by polling the idle bit in the status register (TIS and RIS). 25.11 Compressed Mode Data Compressed mode data is defined in the IEC 61937 specification. This module only detects compressed mode data. This is done by checking the parity flag (V flag) and bit 1 in the channel status data. If both are one then the data is in compressed mode. This is indicated by the setting of the CMD bit in the status register. Note: Only the receiver detects compressed mode data since the information is not relevant to the transmitter. 25.12 References IEC60958 Digital Audio Interface IEC61937 Compressed Mode Digital Audio Interface R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1367 of 3088 Section 25 Renesas SPDIF Interface 25.13 SH7268 Group, SH7269 Group Usage Notes 25.13.1 Clearing TUIR After TUI is written to, the TUIR bit is cleared only after transmission of a maximum of one frame is completed. When using a transmitter user information interrupt to write data to TUI, check that the TUIR bit is cleared before terminating the interrupt handling routine so that the interrupt is not unexpectedly accepted again. 25.13.2 Frequency of Clock Input for Audio The frequency of the clock input to the AUDIO_X1 and AUDIO_X2 or AUDIO_CLK must be lower than the P1 frequency.

When the medium 1 is CD-DA* , the data stream is not input to the CD-ROM decoder because it consists of PCM data. 2 In the case of CD-ROM* , the stream of data is input and the CD-ROM decoder performs sync code detection and maintenance, descrambling, ECC correction, and EDC checking, and outputs the resulting stream of data. However, since the stream received by the CD-ROM decoder is assumed to consist of data from a CD-ROM transferred via the serial sound interface, the decoder does not bother with the subcodes defined in the CD-DA standard. Notes: 1. Compliant with JIS S 8605 (Red Book) 2. Compliant with JIS X 6281 (Yellow Book) 26.1 Features * Sync-code detection and maintenance Detects sync codes from the CD-ROM and is capable of providing sync-code maintenance (automatic interpolation of sync codes) when the sync code cannot be detected because of defects such as scratches on the disc. Five sector-synchronization modes are supported: automatic sync maintenance mode, external sync mode, interpolated sync mode, and interpolated sync plus external sync mode. * Descrambling * ECC support P-parity-based correction, Q-parity-based correction, PQ correction, and QP correction are available. PQ correction and QP correction can be applied repeatedly up to three times. This, however, depends on the speed of the CD. For example, three iterations are possible when the CD-ROM decoder is operating at 60 MHz with a double-speed CD drive. Two buffers are provided due to the need for ECC correction. This allows parallel operation, where ECC correction is performed in one buffer while the data stream is being received in the other. * EDC checking The EDC is checked before and after correction based on the ECC. Furthermore, an operating mode is available in which, if the result of pre-correction EDC checking indicates no errors, ECC correction is not performed regardless of the result of syndrome calculation.

The core includes sufficient memory to hold two sectors. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1371 of 3088 SH7268 Group, SH7269 Group Section 26 CD-ROM Decoder Input data come from the internal bus and output data go out via the internal bus along a single line each, but the bus bridge logic sets up branches for the register access port and stream data port. The stream data from the CD-DSP are transferred via the serial sound interface to the stream data input control block. They are then subjected to descrambling, ECC correction, and EDC checking as they pass through the CD-ROM decoder. After these processes, data from one sector are obtained. The data are subsequently transferred to the stream-data buffer via the stream-data output control block. Data can be transferred by either the direct memory access controller or the CPU. Figure 26.3 is a block diagram of the bus-bridge logic. Since the input stream is transferred over the serial sound interface, transfer is relatively slow. On the other hand, data from the output stream can be transferred at high speeds because they are already in the core of the CD-ROM decoder. Since the data for output are buffered in SDRAM or other memory, they must be transferred at high speeds in order to reduce the busy rate of the SDRAM. For this reason, the data for the output stream are read out before the CD-ROM decoder receives an output stream data read request from the internal bus. This allows the accumulation of streaming data in the registers of the bus bridge, so that the data are ready for immediate output to the internal bus upon a request from the internal bus. Accordingly, the reception of a request to read from registers other than the stream-data registers after the stream data has already been read out and stored in the register of the bus bridge is possible. To cope with this, the CD-ROM decoder is provided with separate intermediary registers for the output stream-data register and the other registers. Input data from the internal bus Data for output to the internal bus Buffer control signal for the output stream-data section Input stream data Register data (write) Register data (read) Output stream data Output stream-data control signal Figure 26.3 Schematic Diagram of the Bus Bridge Page 1372 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 26 CD-ROM Decoder Figure 26.4 is a schematic diagram of the stream-data input control block. The stream-data input controller contains logic that controls the stream of input data and a register that is used to change the control mode of the CD-ROM decoder. The serial sound interface mode used to transfer the stream data may affect the order (through the endian setting) or lead to padding before the data is transferred. To handle the different arrangements of data appropriately, the stream-data input control block includes a register for changing the operating mode and generates signals to control the core of the CD-ROM decoder. The data holding registers for the input stream consists of two 16-bit registers. The data holding registers are controlled according to the mode set in the control register. For example, controlling the order in which 16-bit data is supplied to the core of the CD-ROM decoder (sending the second 16-bytes first or vice versa). It is also possible to stop the supply of padding data to the core of the CD-ROM decoder.

On recognizing that one sector of CD-ROM data is ready in the core of the CD-ROM decoder, this block ensures that the output stream-data register in the bus bridge section is empty and then starts to acquire the data for output from the core of the CD-ROM decoder.

In some systems, however, the order of the data from the serial sound interface may have to be changed or the data will have been padded before transfer. To cope with this, the stream data input control section is capable of swapping the order of the data and preventing the input of padding data to the core of the CD-ROM decoder. These functions are controlled through the serial sound interface data control register (SSI). Figure 26.6 shows a case where the upper and lower 16 bits of the data, consisting of padding data plus the first 2 bytes of sync code, that is, H'000000FF, are swapped (H'00FF0000) and input to the CD-ROM decoder as the stream data.

However, a scratch on the disc or some other factor might lead to erroneous recognition of the sync code sequence at the wrong time. Conversely, a sync code might not be detected at a point where it should be detected. As a solution to these problems, the CD-ROM decoder of this LSI has a sync-code maintenance function, which operates to ignore sync codes detected at abnormal times and maintain the appearance of the sync code at the expected times when it is not actually detected on the disc. The operating modes of the sync-code maintenance function are listed below. For details on the settings, refer to section 26.3.2, Sync Code-Based Synchronization Control Register (CROMSY0), and table 26.2. * Automatic sync maintenance mode * External sync mode * Interpolated sync mode * Interpolated sync plus external sync mode R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1421 of 3088 SH7268 Group, SH7269 Group Section 26 CD-ROM Decoder (1) Automatic Sync Maintenance Mode In automatic sync maintenance mode, the sync code is ignored if detected within the one-sector (2352-byte) period. Furthermore, if a sync code is not detected at the point where a next sector should start, sync code maintenance is applied. If synchronization timing has changed, resynchronization is performed at the point where a sync code is detected within 2352 bytes after the change. Therefore, this mode is effective in rejecting abnormal sync patterns and following changes in synchronization timing. Note, however, that this mode cannot achieve synchronization with the first sector after a change to the synchronization timing. Figure 26.8 shows operation in the case of normal sync-code detection, figure 26.9 shows a case where a sync code is detected before a current one-sector period has elapsed, and figure 26.10 shows the case where the actual sync code is only detected some time after a full one-sector period has elapsed.

Even if the next sync code is not detected at the 2352nd byte, decoding does not proceed until the next sync code is detected. Accordingly, this mode is effective in that it strictly follows the external synchronization timing. Note, however, that decoding will not be performed normally when the sync-code pattern is input with abnormal timing. Figure 26.11 shows the operation in external sync mode. Input data Sync code detection Abnormal sector Sector 1 Output data Sector 3 Sector 1 Sector 4 Sector 3 Sector 5 Sector 4 Abnormal sector Figure 26.11 Operation in External Sync Mode R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1423 of 3088 SH7268 Group, SH7269 Group Section 26 CD-ROM Decoder (3) Interpolated Sync Mode In interpolated sync mode, synchronization is always driven by the internal counter after a sync code pattern has been detected at the start of decoding. Accordingly, this mode is effective when the sync patterns have been damaged. However, decoding becomes incorrect after a change to the synchronization timing, since the change in timing is not followed. Figure 26.12 shows the operation in interpolated sync mode.

Synchronization in this mode is more quickly responsive to changes in synchronization timing than synchronization in the automatic sync maintenance mode. However, decoding still becomes incorrect when a sync pattern is input with abnormal timing. Figures 26.13 and 26.14 show the operation in interpolated sync plus external sync mode in the cases of abnormally short and long sectors, respectively.

The CD-ROM decoder includes the following functions for use in error correction. * Syndrome calculation * ECC correction * EDC checking (1) Syndrome Calculation After the data of a sector in Mode 1 or Form 1 of Mode 2 has been input, the ECC is used in correction if any error is detected (the result of syndrome calculation is non-zero). After correction, the results of syndrome operation for the corrected data are output to bits ST_ECCP (P parity) and ST_ECCQ (Q parity) in the CROMST6 register, respectively. (2) ECC correction and EDC Checking For CD-ROM format data that contains EDC, P-parity, and Q-parity fields, the CD-ROM decoder performs EDC checking and ECC correction. Supported correction modes are P correction, Q correction, PQ correction (P correction followed by Q correction), and QP correction (Q correction followed by P correction). In PQ and QP correction modes, up to three iterations of correction are possible (the number of iterations is limited by the playback speed). The EDC check is performed twice, before and after correction. The mode of ECC correction and EDC checking is specified by bits MD_DEC[2:0] in the CROMCTL1 register. When the PQ or QP correction mode is selected, the number of iterations is specified by bits MD_PQREP[1:0] in the CROMCTL1 register. When the automatic mode/form detection function is in use, the sector mode determines whether or not ECC correction and EDC checking can be performed. For sectors in Mode 0 and Mode 2 (non-XA), which include neither parity bits nor EDC, ECC correction and EDC checking are not performed. For sectors in Form 2 of Mode 2, ECC correction is not performed. (a) ECC Correction When ECC correction is in use and an error in a sector is identified as non-correctable, the CDROM decoder generates an IERR interrupt and sets the ST_ECCNG bit of the CROMST6 register to 1. The CD-ROM detector also sets this bit to 1 on detecting a short sector. Page 1426 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 26 CD-ROM Decoder While the NO_ECC bit of the CROMCTL4 register is set to 1, a `pass' result in pre-correction EDC checking makes the CD-ROM decoder skip ECC correction, regardless of the results of the syndrome operation. (b) EDC Checking When EDC checking is in use, checking is in line with the specified or detected sector mode and form, depending on whether or not automatic sector mode and form detection is selected. The results of EDC checking before and after correction are reflected in the ST_EDC1 and ST_EDC2 bits of the CROMST6 register, respectively. If EDC checking after ECC correction indicates that an error remains, an IERR interrupt is generated. 26.4.4 Automatic Decoding Stop Function Decoding can be stopped automatically in response to an error during the decoding of CD-ROM data. The possible conditions for automatically stopping the decoding process are listed below. The applicable conditions are specified in the CROMCTL3 register. * An error is found to be not correctable by ECC correction. * Post-correction EDC checking indicates that an error remains. * A change of the sector mode or form. * A non-sequential MSF (minutes, seconds, frames (1/75 second)) value. When automatic stopping is set up and any of the above conditions is encountered in a certain sector, the decoding is stopped after the results of decoding for that sector have been output. After decoding has been stopped in response to a condition specified in the CROMCTL3 register, the condition can be identified by reading the CBUFST1 register. The CD-ROM decoder has buffer space for two sectors. If input of the data stream continues and the output stream of data is not read, the CD-ROM decoder stops at the point where the data of a third sector starts to be input. At this time, the BUF_NG bit in the CBUFST2 register is set to 1, but no interrupt is generated. Once the BUF_NG bit in the CBUFST2 register has been set to 1, recovery can only be accomplished by using the LOGICRST bit in the ROMDECRST register to reset the CD-ROM decoder function. When the LOGICRST bit in the ROMDECRST register is set to 1, a reset signal is output and any registers in which settings have been made are cleared to their initial values.

The following describes the procedures for setting the registers in the CD-ROM decoder to set up automatic or manual buffering. (1) Setting Up Automatic Buffering Figure 26.16 shows an example of setting up the automatic buffering. Set the relevant CD-ROM decoder registers and start input of the data stream; the CD-ROM decoder then detects the target sector and starts the output of the stream data.

[2] Set the minutes value of the target sector. [3] Set the seconds value of the target sector. [4] Set the frame value of the target sector. Set CBUFCTL2 [3] [5] Enable subcode processing and CD-ROM decoding. Set CBUFCTL3 [4] Set both the SUBC_EN and CROM_EN bits in CROMEN to 1 [5] End of automatic buffering setup Figure 26.16 Example of Setting Up Automatic Buffering Page 1430 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (2) Section 26 CD-ROM Decoder Setting Up Manual Buffering Figure 26.17 shows an example of setting up manual buffering. Each time an ISEC interrupt is generated, the software checks whether or not the sector is the target sector and starts buffering when the target sector is found. Start of automatic buffering setup Clear both the CBUF_AUT and CBUF_EN bits in CBUFCTL0 to 0 [1] [1] Turn off the automatic buffering function and disable buffering in the buffer RAM. [2] Enable subcode processing and CD-ROM decoding. Set both the CBUF_AUT and CBUF_EN bits in CBUFCTL0 to 1 [2] Generation of an ISEC interrupt [3] [3] Start input of the data stream.

Table 26.3 Interrupt and DMA Transfer Request Signals Name Condition Connected To ISEC Transitions from sector to sector Interrupt controller ITARG Access to a CD-ROM sector that is not the expected target sector Interrupt controller ISY A sync code from the CD-ROM with abnormal timing Interrupt controller IERR An error that was not correctable by ECC correction or an error indicated by EDC checking after ECC correction Interrupt controller IBUF State changes in data transfer to the buffer Interrupt controller IREADY Request for data transfer to the buffer for CD-ROM Interrupt controller DMA transfer request Request for data transfer to the buffer for CD-ROM Direct memory access controller (1) ISEC Interrupt This interrupt is generated when the sync code indicates a transition from sector to sector. (2) ITARG Interrupt This interrupt is generated when the stream data transferred from the CD-DSP is not the data of the target sector. The CD-ROM decoder checks the time data in the subcode. In correct operation, data transfer is expected to start slightly before the target sector. An ITARG interrupt is generated in the following cases. * When data of a sector preceding the target sector by quite a few sectors have been transferred * When data of a sector that comes after the target sector have been transferred For the generation of this interrupt, ITARG is detected from the subcode. However, this interrupt has no meaning in this LSI because CD-ROM data are transferred from the serial sound interface. Page 1432 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (3) Section 26 CD-ROM Decoder ISY Interrupt This interrupt can be generated in the following cases. * When a sync code was detected at a position where the value in the word counter (counter for checking sync code intervals) was not correct and the sync code was ignored * When a sync code has not been detected although the word counter has reached the final value and a sync code has been interpolated (for sync maintenance) * When a sync code was detected at a position where the value in the word counter (counter for checking sync code intervals) was not correct and the sync code was used in resynchronization * When a sync code has not been detected although the word counter has reached the final value, so the period taken up by the sector has been prolonged * When the sector has been processed as a short sector with the aid of interpolated sync codes * When the sector has been processed as a long sector with the aid of interpolated sync codes (4) IERR Interrupt This interrupt is generated in the following cases. * When ECC correction was incapable of correcting an error * When ECC correction was OK but the subsequent EDC check indicated an error (5) IBUF Interrupt This interrupt is generated when the following transitions occur. * Data transfer to the buffer Data transfer complete (searching for data for the next transfer) * Data for transfer to the buffer are being searched for Data transfer started (6) IREADY Interrupt This interrupt is generated when decoding of data for one sector is completed. This interrupt should be used to start the CPU buffering stream data for output to SDRAM. (7) DMA Transfer Request The source of direct memory access controller activation is the same as that of IREADY. An interrupt request is generated when output stream data for one sector becomes ready, and after the 2768 bytes of data shown in figure 26.15 have been transferred, the request signal is negated once. This is because a certain amount of time is required before the output data for the next sector is ready, so the transfer request from the direct memory access controller should be turned off between transfers. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1433 of 3088 Section 26 CD-ROM Decoder 26.5.2 SH7268 Group, SH7269 Group Timing of Status Registers Updates The status information registers of the CD-ROM decoder are updated on each ISEC interrupt. The sector for which information is reflected in the status registers is selected by the ER0SEL bit of the CROMCTL4 register. 26.6 Usage Notes 26.6.1 Stopping and Resuming Buffering Alone during Decoding When the data of the output stream are being not read out but operation of the CD-ROM decoder has continued until the buffers are full, the BUF_NG bit in the CBUFST2 register is set to 1; after that, the CD-ROM decoder becomes incapable of operation. To stop buffering alone, clear the CBUF_EN bit in the CBUFCTL0 register to 0. If the automatic buffering function is in use, clear the CBUF_AUT in the CBUFCTL0 register to 0 at the same time. In this case, the sectors currently in the buffers must be read out. To resume automatic buffering, set the CBUF_AUT and CBUF_EN bits in the CBUFCTL0 register at the same time. 26.6.2 When CROMST0 Status Register Bits are Set 1. When the ST_SECS bit in the CROMST0 register becomes set, stop decoding immediately and retry from one sector before the sector that was being decoded. 2. When the ST_SECL bit in the CROMST0 register becomes set, stop decoding immediately and retry from two sectors before the sector that was being decoded. Page 1434 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 26.6.3 Section 26 CD-ROM Decoder Link Blocks The CD-ROM decoder uses the header information before ECC correction to detect link blocks. Accordingly, an input data stream that contains an error may be erroneously detected as a link block. To prevent this, the following measures should be implemented in software. * During buffering (BUF_ACT = 1 in the CBUFST0 register), check the LINK_OUT1 bit in the CROMST5 register on each ISEC interrupt. If it is set to 1, check to see if an IERR interrupt has also occurred; if an IERR interrupt has not occurred, save the MFS values from the HEAD20 to HEAD23 registers. If an IERR interrupt has occurred, do not save the MSF values. * Perform the following processing for seven sectors (indicated by ISEC being generated seven times) after finding that the LINK_OUT1 bit has been set to 1. In either of cases 1 and 2 below, 1. LINK_ON = 1 (in the CROMST5 register) is confirmed at each ISEC interrupt, and LINK_ON = 1 is detected again within the subsequent two-sector period 2. LINK_ON = 1 was not detected at any ISEC interrupt Forcibly stop decoding, set the CROMSY0 register to place the decoder in external sync mode, and retry decoding by specifying the MSF value stored above + 7 as the MSF value for the target sector. The start sector address will be the address where RUN_OUT is stored + 7 when CBUF_LINK = 0, and the address where RUN_OUT is stored when CBUF_LINK = 1. 26.6.4 Stopping and Resuming CD-DSP Operation When stopping and resuming the stream data input to the CD-ROM decoder, note that the input data stream does not stop immediately before a sync code and that the CD-ROM decoder may recognize the data as incorrect when the input stream is resumed. This happens because the system holds a combination of the data up to the point where input was stopped and data that is input from the point of resumption. Take care on this point when stopping and resuming input. 26.6.5 Note on Clearing the IREADY Flag To clear the IREADY flag to 0 in interrupt processing etc., be sure to read one sector of data (2768 bytes) beforehand. If the IREADY flag is cleared to 0 before reading of one sector of data is complete, decoding of the subsequent sectors will not be possible. For recovery from this situation, write 1 to the LOGICRST bit in the CD-ROM decoder reset control register (ROMDECRST), and then clear the bit to 0.

This causes the CD-ROM decoder to be abnormally stopped. Caution is required in writing and reading of the stream data. Sample combinations of stream data transfer settings are shown below.

An A/D conversion produces 10-bit data, which is transferred for storage into the ADDR corresponding to the selected channel. The 10 bits of the result are stored in the upper bits (bits 15 to 6) of ADDR. Bits 5 to 0 of ADDR are reserved bits that are always read as 0. Access to ADDR in 8-bit units is prohibited. ADDR must always be accessed in 16-bit units. Table 27.3 indicates the pairings of analog input channels and ADDR.

It has three operating modes: single mode, multi mode, and scan mode. Switching the operating mode or analog input channels must be done while the ADST bit in ADCSR is 0 to prevent incorrect operation. The ADST bit can be set at the same time as the operating mode or analog input channels are changed. 27.4.1 Single Mode Single mode should be selected when only A/D conversion on one channel is required. In single mode, A/D conversion is performed once for the specified one analog input channel, as follows: 1. A/D conversion for the selected channel starts when the ADST bit in ADCSR is set to 1 by software, the multi-function timer pulse unit 2, or external trigger input. 2. When A/D conversion is completed, the A/D conversion result is transferred to the A/D data register corresponding to the channel. 3. After A/D conversion has completed, the ADF bit in ADCSR is set to 1. If the ADIE bit is set to 1 at this time, an ADI interrupt request is generated. 4. The ADST bit that remains 1 during A/D conversion is automatically cleared to 0 when A/D conversion is completed, and the A/D converter becomes idle. When the operating mode or analog input channel selection must be changed during A/D conversion, to prevent incorrect operation, first clear the ADST bit to 0 to halt A/D conversion. After making the necessary changes, set the ADST bit to 1 to start A/D conversion again. The ADST bit can be set at the same time as the mode or channel selection is switched. Page 1446 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 27 A/D Converter Typical operations when a single channel (AN1) is selected in single mode are described next. Figure 27.2 shows a timing diagram for this example (the bits which are set in this example belong to ADCSR). 1. Single mode is selected, input channel AN1 is selected (CH[2:0] = 001), the A/D interrupt is enabled (ADIE = 1), and A/D conversion is started (ADST = 1). 2. When A/D conversion is completed, the A/D conversion result is transferred into ADDRB. At the same time the ADF flag is set to 1, the ADST bit is cleared to 0, and the A/D converter becomes idle. 3. Since ADF = 1 and ADIE = 1, an ADI interrupt is requested. 4. The A/D interrupt handling routine starts. 5. The routine reads ADF = 1, and then writes 0 to the ADF flag. 6. The routine reads and processes the A/D conversion result (ADDRB). 7. Execution of the A/D interrupts handling routine ends. Then, when the ADST bit is set to 1, A/D conversion starts and steps 2 to 7 are executed.

In multi mode, A/D conversion is performed once for a maximum of eight specified analog input channels, as follows: 1. A/D conversion starts from the analog input channel with the lowest number (e.g. AN0, AN1, ..., AN3) when the ADST bit in ADCSR is set to 1 by software, the multi-function timer pulse unit 2, or external trigger input. 2. When A/D conversion is completed on each channel, the A/D conversion result is sequentially transferred to the A/D data register corresponding to that channel. 3. After A/D conversion on all selected channels has completed, the ADF bit in ADCSR is set to 1. If the ADIE bit is set to 1 at this time, an ADI interrupt request is generated. 4. The ADST bit that remains 1 during A/D conversion is automatically cleared to 0 when A/D conversion is completed, and the A/D converter becomes idle. If the ADST bit is cleared to 0 during A/D conversion, A/D conversion is halted and the A/D converter becomes idle. The ADF bit is cleared by reading ADF while ADF = 1, then writing 0 to the ADF bit. A/D conversion is to be performed once on all the specified channels. The conversion results are transferred for storage into the A/D data registers corresponding to the channels. When the operating mode or analog input channel selection must be changed during A/D conversion, to prevent incorrect operation, first clear the ADST bit to 0 to halt A/D conversion. After making the necessary changes, set the ADST bit to 1. A/D conversion will start again from the first channel in the group. The ADST bit can be set at the same time as the mode or channel selection is changed. Typical operations when three channels (AN0 to AN2) are selected in multi mode are described next. Figure 27.3 shows a timing diagram for this example. 1. Multi mode is selected (MDS2 = 1, MDS1 = 0), analog input channels AN0 to AN2 are selected (CH[2:0] = 010), and A/D conversion is started (ADST = 1). 2. A/D conversion of the first channel (AN0) starts. When A/D conversion is completed, the A/D conversion result is transferred into ADDRA. 3. Next, the second channel (AN1) is selected automatically and A/D conversion starts. 4. Conversion proceeds in the same way through the third channel (AN2). 5. When conversion of all selected channels (AN0 to AN2) is completed, the ADF flag is set to 1 and the ADST bit cleared to 0. 6. If the ADIE bit is set to 1 at this time, an ADI interrupt is requested.

In scan mode, A/D conversion is performed sequentially for a maximum of eight specified analog input channels, as follows: 1. A/D conversion starts from the analog input channel with the lowest number (e.g. AN0, AN1, ..., AN3) when the ADST bit in ADCSR is set to 1 by software, the multi-function timer pulse unit 2, or external trigger input. 2. When A/D conversion is completed on each channel, the A/D conversion result is sequentially transferred to the A/D data register corresponding to that channel. 3. After A/D conversion on all selected channels has completed, the ADF bit in ADCSR is set to 1. If the ADIE bit is set to 1 at this time, an ADI interrupt request is generated. The A/D converter starts A/D conversion again from the channel with the lowest number. 4. The ADST bit is not cleared automatically, so steps 2. and 3. are repeated as long as the ADST bit remains set to 1. When the ADST bit is cleared to 0, A/D conversion halts and the A/D converter becomes idle. The ADF bit is cleared by reading ADF while ADF = 1, then writing 0 to the ADF bit. When the operating mode or analog input channel selection must be changed during A/D conversion, to prevent incorrect operation, first clear the ADST bit to 0 to halt A/D conversion. After making the necessary changes, set the ADST bit to 1. A/D conversion will start again from the first channel in the group. The ADST bit can be set at the same time as the mode or channel selection is changed. Typical operations when three channels (AN0 to AN2) are selected in scan mode are described as follows. Figure 27.4 shows a timing diagram for this example. 1. Scan mode is selected (MDS2 = 1, MDS1 = 1), analog input channels AN0 to AN2 are selected (CH[2:0] = 010), and A/D conversion is started (ADST = 1). 2. A/D conversion of the first channel (AN0) starts. When A/D conversion is completed, the A/D conversion result is transferred into ADDRA. 3. Next, the second channel (AN1) is selected automatically and A/D conversion starts. 4. Conversion proceeds in the same way through the third channel (AN2). 5. When conversion of all the selected channels (AN0 to AN2) is completed, the ADF flag is set to 1 and conversion of the first channel (AN0) starts again. If the ADIE bit is set to 1 at this time, an ADI interrupt is requested. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1451 of 3088 Section 27 A/D Converter SH7268 Group, SH7269 Group 6. The ADST bit is not cleared automatically, so steps 2. to 4. are repeated as long as the ADST bit remains set to 1. When steps 2. to 4. are repeated, the ADF flag is kept to 1. When the ADST bit is cleared to 0, A/D conversion stops. The ADF bit is cleared by reading ADF while ADF = 1, then writing 0 to the ADF bit. If both the ADF flag and ADIE bit are set to 1 while steps 2. to 4. are repeated, an ADI interrupt is requested at all times. To generate an interrupt on completing conversion of the third channel, clear the ADF bit to 0 after an interrupt is requested.

To activate the A/D converter by an external trigger or the multi-function timer pulse unit 2, set the A/D trigger enable bits (TRGS[3:0]). When an external trigger or an A/D conversion request from the multi-function timer pulse unit 2 is generated with this bit setting, the ADST bit is set to 1 to start A/D conversion. The channel combination is determined by bits CH2 to CH0 in ADCSR. The timing from setting of the ADST bit until the start of A/D conversion is the same as when 1 is written to the ADST bit by software. 27.4.5 Input Sampling and A/D Conversion Time The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog input at the A/D conversion start delay time (tD) after the ADST bit in ADCSR is set to 1, then starts conversion. Figure 27.5 shows the A/D conversion timing. Table 27.4 indicates the A/D conversion time. As indicated in figure 27.5, the A/D conversion time (tCONV) includes tD and the input sampling time(tSPL). The length of tD varies depending on the timing of the write access to ADCSR. The total conversion time therefore varies within the ranges indicated in table 27.4. In multi mode and scan mode, the values given in table 27.4 apply to the first conversion. In the second and subsequent conversions, time is the values given in table 27.5.

When the TRGS[3:0] bits in ADCSR are set to B'1001, an external trigger is input to the ADTRG pin. The ADST bit in ADCSR is set to 1 at the falling edge of the ADTRG pin, thus starting A/D conversion. Other operations, regardless of the operating mode, are the same as when the ADST bit has been set to 1 by software. Figure 27.6 shows the timing. P1 ADTRG Internal trigger signal ADST A/D conversion Figure 27.6 External Trigger Input Timing R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1457 of 3088 SH7268 Group, SH7269 Group Section 27 A/D Converter 27.5 Interrupt Sources and DMA Transfer Request The A/D converter generates an A/D conversion end interrupt (ADI) at the end of A/D conversion. An ADI interrupt request is generated if the ADIE bit is set to 1 when the ADF bit in ADCSR is set to 1 on completion of A/D conversion. Note that the direct memory access controller can be activated by an ADI interrupt depending on the setting of the direct memory access controller. In this case, an interrupt is not issued to the CPU. If the setting to activate the direct memory access controller has not been made, an interrupt request is sent to the CPU. Having the converted data read by the direct memory access controller in response to an ADI interrupt enables continuous conversion to be achieved without imposing a load on software. In single mode, set the direct memory access controller so that DMA transfer initiated by an ADI interrupt is performed only once. In the case of A/D conversion on multiple channels in scan mode or multi mode, setting the DMA transfer count to one causes DMA transfer to finish after transferring only one channel of data. To make the direct memory access controller transfer all conversion data, set the ADDR where A/D conversion data is stored as the transfer source address, and the number of converted channels as the transfer count. When the direct memory access controller is activated by ADI, the ADF bit in ADCSR is automatically cleared to 0 when data is transferred by the direct memory access controller.

The absolute accuracy of this A/D conversion is the deviation between the input analog value and the output digital value. It includes the following errors: * Offset error * Full-scale error * Quantization error * Nonlinearity error These four error quantities are explained below with reference to figure 27.7. In the figure, the 10bit A/D converter is illustrated as the 3-bit A/D converter for explanation. Offset error is the deviation between actual and ideal A/D conversion characteristics when the digital output value changes from the minimum (zero voltage) B'0000000000 (000 in the figure) to B'000000001 (001 in the figure)(figure 27.7, item (1)). Full-scale error is the deviation between actual and ideal A/D conversion characteristics when the digital output value changes from B'1111111110 (110 in the figure) to the maximum B'1111111111 (111 in the figure)(figure 27.7, item (2)). Quantization error is the intrinsic error of the A/D converter and is expressed as 1/2 LSB (figure 27.7, item (3)). Nonlinearity error is the deviation between actual and ideal A/D conversion characteristics between zero voltage and full-scale voltage (figure 27.7, item (4)). Note that it does not include offset, full-scale, or quantization error.

The initial setting is for operation of the A/D converter to be halted. Register access is enabled by clearing module standby mode. For details, see section 49, Power-Down Modes. 27.7.2 Setting Analog Input Voltage Permanent damage to the LSI may result if the following voltage ranges are exceeded. 1. Analog input range During A/D conversion, voltages on the analog input pins ANn should not go beyond the following range: AVss ANn AVcc (n = 0 to 7). 2. AVcc and AVss input voltages Input voltages AVcc and AVss should be PVcc - 0.3 V AVcc PVcc and AVss = Vss. Do not leave the AVcc and AVss pins open when the A/D converter is not in use and in software standby mode. When not in use, connect AVcc to the power supply (PVcc) and AVss to the ground (Vss). 3. Setting range of AVref input voltage Set the reference voltage range of the AVref pin as 3.0 V AVref AVcc. 27.7.3 Notes on Board Design In board design, digital circuitry and analog circuitry should be as mutually isolated as possible, and layout in which digital circuit signal lines and analog circuit signal lines cross or are in close proximity should be avoided as far as possible. Failure to do so may result in incorrect operation of the analog circuitry due to inductance, adversely affecting A/D conversion values. Digital circuitry must be isolated from the analog input signals (AN0 to AN3), analog reference voltage (AVref), and analog power supply (AVcc) by the analog ground (AVss). Also, the analog ground (AVss) should be connected at one point to a stable digital ground (Vss) on the board.

The circuit shown also includes a CR filter to suppress noise. This circuit is shown as an example; the circuit constants should be selected according to actual application conditions.

Unit Analog input capacitance 20 pF Allowable signal-source impedance 5 k 27.7.5 Permissible Signal Source Impedance This LSI's analog input is designed such that conversion precision is guaranteed for an input signal for which the signal source impedance is 5 k or less. This specification is provided to enable the A/D converter's sample-and-hold circuit input capacitance to be charged within the sampling time; if the sensor output impedance exceeds 5 k, charging may be insufficient and it may not be possible to guarantee A/D conversion precision. However, for A/D conversion in single mode with a large capacitance provided externally for A/D conversion in single mode, the input load will essentially comprise only the internal input resistance of 3 k, and the signal source impedance is ignored. However, as a low-pass filter effect is obtained in this case, it may not be possible to follow an analog signal with a large differential coefficient (e.g., 5 mV/s or greater) (see figure 27.10). When converting a high-speed analog signal, a low-impedance buffer should be inserted.

Figure 27.10 Example of Analog Input Circuit 27.7.6 Influences on Absolute Precision Adding capacitance results in coupling with GND, and therefore noise in GND may adversely affect absolute precision. Be sure to connect AVss, etc. to an electrically stable GND. Care is also required to insure that filter circuits do not interfere with digital signals on the mounting board (i.e., acting as antennas). 27.7.7 Note on Usage in Scan Mode and Multi Mode Starting conversion immediately after having stopped scan mode or multi mode operation may lead to erroneous results of conversion. To perform continuous conversion in such cases, set ADST to 0, wait for at least the A/D conversion time for a single channel to elapse, and then start conversion (ADST = 1). (The A/D conversion time for a single channel will vary according to the settings of the ADC registers.)

The data in the status register is input through the I/O7 to I/O0 pins and stored in the bits STAT[7:0] in FLBSYCNT, which can be read by the CPU. If a program error or erase error is detected when the status register value is stored in the bits STAT[7:0] in FLBSYCNT, the STERB bit in FLINTDMACR is set to 1 and generates an interrupt to the CPU if the STERINTE bit in FLINTDMACR is enabled. If a status error occurs during continuous sector access, the TREND bit in FLTRCR is set to 1 and the procedure stops. (1) Status Read of NAND-Type Flash Memory The status register of NAND-type flash memory can be read by inputting command H'70 to NAND-type flash memory. If programming is executed in command access mode or sector access mode while the DOSR bit in FLCMDCR is set to 1, this module automatically inputs command H'70 to NAND-type flash memory and reads the status register of NAND-type flash memory. When the status register of NAND-type flash memory is read, the I/O7 to I/O0 pins indicate the following information as described in table 28.3. Table 28.3 Status Read of NAND-Type Flash Memory I/O Status (definition) I/O7 Program protection Description 0: Cannot be programmed 1: Can be programmed I/O6 Ready/busy 0: Busy state 1: Ready state I/O5 to I/O1 Reserved I/O0 Program/erase 0: Pass 1: Fail Page 1504 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 28.5 Section 28 NAND Flash Memory Controller Interrupt Sources This module has five interrupt sources: Status error, ready/busy timeout error, transfer end, FIFO0 transfer request, and FIFO1 transfer request. Each of the interrupt sources has its corresponding interrupt flag and the interrupt can be requested independently to the CPU if the interrupt is enabled by the interrupt enable bit. Note that the status error and ready/busy timeout error use the common FLSTE interrupt to the CPU.

With bit 21 (BUSYON) set to 0 in the common control register (FLCMNCR), this module negates FCE and releases the bus mastership even during the busy state upon completion of the process. With BUSYON = 0, setting bit 24 (DOSR) in the command control register (FLCMDCR) to 1 to read the status enables acquiring the bus mastership even during the busy state.

The module controls the output time of a remote wakeup signal. When this bit is set to 1, this module clears this bit to 0 after outputting the 10-ms K state. According to the USB specification, the USB bus idle state must be kept for 5 ms or longer before a remote wakeup signal is output. If this module writes 1 to this bit right after detection of suspended state, the K state will be output after 2 ms. Note: Do not write 1 to this bit, unless the device state is in the suspended state (the DVSQ bit in the INTSTS0 register is set to 1xx) and the USB host enables the remote wakeup signal. When this bit is set to 1, the internal clock must not be stopped even in the suspended state (write 1 to this bit while SCKE is 1). This bit should be set to 0 if the host controller function is selected.

With this bit set to 1, on detecting the remote wakeup signal, this module detects the resume signal (Kstate for 2.5 s) from the downstream port device and performs the resume process (drives the port to the K-state). With this bit set to 0, this module ignores the detected remote wakeup signal (K-state) from the peripheral device connected to the downstream port. While this bit is 1, the internal clock should not be stopped even in the suspended state (SCKE should be set to 1). Also note that the USB bus should not be reset from the suspended state (USBRST should not be set to 1); it is prohibited by USB Specification 2.0. This bit should be set to 0 if the function controller function is selected.

When the host controller function is selected, setting this bit to 1 allows this module to drive the USB port to SE0 to reset the USB bus. Here, this module performs the reset handshake protocol if the HSE bit is 1. This module continues outputting SE0 while USBRST is 1 (until 0 is written to USBRST). USBRST should be 1 (= USB bus reset period) for the time defined by USB Specification 2.0. Writing 1 to this bit during communication (UACT = 1) or during the resume process (RESUME = 1) prevents this module from starting the USB bus reset process until both UACT and RESUME become 0. Write 1 to the UACT bit simultaneously with the end of the USB bus reset process (writing 0 to USBRST). This bit should be set to 0 if the function controller function is selected. 5 RESUME 0 R/W Resume Output Controls the resume signal output when the host controller function is selected. 0: Resume signal is not output. 1: Resume signal is output. Setting this bit to 1 allows this module to drive the port to the K-state and output the resume signal. This module continues outputting K-state while RESUME is 1 (until 0 is written to RESUME). RESUME should be 1 (= resume period) for the time defined by USB Specification 2.0. This bit should be set to 1 in the suspended state. Write 1 to the UACT bit simultaneously with the end of the resume process (writing 0 to RESUME). This bit should be set to 0 if the function controller function is selected.

With this bit set to 1, this module puts the USB port to the USB-bus enabled state and performs SOF output and data transmission and reception. This module starts outputting SOF/SOF within 1 () frame after 1 has been written to UACT. With this bit set to 0, this module enters the idle state after outputting SOF/SOF. This module sets this bit to 0 on any of the following conditions. * A DTCH interrupt is detected during communication (while UACT = 1). * An EOFERR interrupt is detected during communication (while UACT = 1). Writing 1 to this bit should be done at the end of the USB bus reset process (writing 0 to USBRST) or at the end of the resume process from the suspended state (writing 0 to RESUME). This bit should be set to 0 if the function controller function is selected. 3 0 R Reserved This bit is always read as 0. The write value should always be 0.

If HSE has been set to 1, these bits indicate 111 as soon as this module detects Chirp-K from the peripheral device. This module fixes the value of the RHST bits when 0 is written to USBRST and this module completes SE0 driving. When the UTST bits are set to 1xxx (when a host test mode is specified), the RHST bits indicate 011. (2) When the function controller function is selected 000: Communication speed not determined 100: Reset handshake in progress 010: Full-speed connection 011: High-speed connection If HSE has been set to 1, these bits indicate 100 as soon as this module detects the USB bus reset. Then, these bits indicate 011 as soon as this module outputs Chirp-K and detects Chirp-JK from the USB host three times. If the connection speed is not fixed to high speed within 2.5 ms after Chirp-K output, these bits indicate 010. If HSE has been set to 0, these bits indicate 010 as soon as this module detects the USB bus reset. A DVST interrupt is generated as soon as this module detects the USB bus reset and then the value of the RHST bits is fixed to 010 or 011. Note: * Only 1 can be written.

When these bits are set to Test_Force_Enable (1101), this module outputs the SOF packet when 1 is set to UACT. In this test mode, this module does not perform hardware control consequent to detection of high-speed disconnection (detection of the DTCH interrupt). When setting the UTST bits, the PID bits for all the pipes should be set to NAK. To return to normal USB communication after a test mode has been set and executed, a power-on reset should be applied.

There are three FIFO ports: the CFIFO, D0FIFO and D1FIFO ports. Each FIFO port is configured of a port register (CFIFO, D0FIFO, D1FIFO) that handles reading of data from the FIFO buffer memory and writing of data to the FIFO buffer memory, a select register (CFIFOSEL, D0FIFOSEL, D1FIFOSEL) that is used to select the pipe assigned to the FIFO port, and a control register (CFIFOCTR, D0FIFOCTR, D1FIFOCTR). Each FIFO port has the following features. * The DCP FIFO buffer should be accessed through the CFIFO port. * Accessing the FIFO buffer using DMA transfer should be performed through the D0FIFO or D1FIFO port. * The D1FIFO and D0FIFO ports can be accessed also by the CPU. * When using functions specific to the FIFO port, the pipe number (selected pipe) specified by the CURPIPE bits cannot be changed (when the DMA transfer function is used, etc.). * Registers configuring a FIFO port do not affect other FIFO ports. * The same pipe should not be assigned to two or more FIFO ports. * There are two FIFO buffer states: the access right is on the CPU side and it is on the SIE side. When the FIFO buffer access right is on the SIE side, the FIFO buffer cannot be accessed from the CPU. These registers are initialized by a power-on reset.

Then, this module switches the FIFO buffer from the CPU side to the SIE side, enabling transmission. * To transmit a short packet, set this bit to 1 after data has been written. * To transmit a zero-length packet, set this bit to 1 before data is written to the FIFO buffer. * Set this bit to 1 after the number of data bytes has been written for the pipe in continuous transfer mode, where the number is a natural integer multiple of the maximum packet size and less than the buffer size. When the data of the maximum packet size has been written for the pipe in non-continuous transfer mode, this module sets this bit to 1 and switches the FIFO buffer from the CPU side to the SIE side, enabling transmission. When the selected pipe is in the transmitting direction, if 1 is written to BVAL and BCLR bits simultaneously, this module clears the data that has been written before it, enabling transmission of a zero-length packet. Writing 1 to this bit should be done while FRDY indicates 1 (set by this module). When the selected pipe is in the receiving direction, do not set this bit to 1.

When double buffer mode is set for the FIFO buffer assigned to the selected pipe, this module clears only one plane of the FIFO buffer even when both planes are read-enabled. When the selected pipe is the DCP, setting BCLR to 1 allows this module to clear the FIFO buffer regardless of whether the FIFO buffer is on the CPU side or SIE side. To clear the buffer on the SIE side, set the PID bits for the DCP to NAK before setting BCLR to 1. When the selected pipe is not the DCP, writing 1 to this bit should be done while FRDY indicates 1 (set by this module). 13 FRDY 0 R FIFO Port Ready Indicates whether the FIFO port can be accessed. 0: FIFO port access is disabled. 1: FIFO port access is enabled. In the following cases, this module sets FRDY to 1 but data cannot be read via the FIFO port because there is no data to be read. In these cases, set BCLR to 1 to clear the FIFO buffer, and enable transmission and reception of the next data. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 * A zero-length packet is received when the FIFO buffer assigned to the selected pipe is empty. * A short packet is received and the data is completely read while BFRE is 1.

The write value should always be 0. 11 to 0 DTLN[11:0] H'000 R Receive Data Length Indicates the length of the receive data. While the FIFO buffer is being read, these bits indicate the different values depending on the RCNT bit value as described below. * RCNT = 0: This module sets these bits to indicate the length of the receive data until all the received data has been read from a single FIFO buffer plane. While BFRE is 1, these bits retain the length of the receive data until BCLR is set to 1 even after all the data has been read. * RCNT = 1: This module decrements the value indicated by these bits each time data is read from the FIFO buffer. (The value is decremented by one when MBW is 00, by two when MBW is 01, and by four when MBW is 10.) This module sets these bits to 0 when all the data has been read from one FIFO buffer plane. However, in double buffer mode, if data has been received in one FIFO buffer plane before all the data has been read from the other plane, this module sets these bits to indicate the length of the receive data in the former plane when all the data has been read from the latter plane. Note: When RCNT is 1, it takes 10 bus cycles for these bits to be updated after the FIFO port has been read. Notes: 1. Only 0 can be read and 1 can be written. 2. Only 1 can be written.

When the function controller function is selected, this module does not reference to this bit during the IN/OUT transaction of the status stage, and does not allow this bit to toggle upon normal completion. 5 PBUSY 0 R Pipe Busy This bit indicates whether or not a transaction using the pertinent pipe is currently in progress. 0: The pertinent pipe is not in use by a transaction. 1: The pertinent pipe is in use by a transaction. The USB 2.0 host/function module changes the setting of the PBUSY bit from 0 to 1 when a USB transaction using the DCP starts. It clears the PBUSY bit from 1 to 0 when one transaction completes successfully. Reading this bit after setting PID to NAK allows checking that modification of the pipe settings is possible. For details, refer to section 29.4.3 (1), Pipe Control Register Switching Procedures.

When having detected the ACK handshake during PING transactions, this module performs the OUT transaction as the next transaction. When having detected the NAK handshake during OUT transactions, this module performs the PING transaction as the next transaction. When the host controller function is selected, setting this bit to 0 prevents this module from issuing the PING token during transfers in the transmitting direction and only allows this module to perform OUT transactions for the transfers in the transmitting direction. These bits should be modified while CSSTS is 0 and PID is NAK. Before changing the value of this bit after changing the PID bits for the DCP from BUF to NAK, confirm that CSSTS and PBUSY are both cleared to 0. However, if the PID bits have been modified to NAK by this module, checking PBUSY is not necessary. When the function controller function is selected, be sure to write 0 to this bit. 3 0 R Reserved This bit is always read as 0. The write value should always be 0.

When this bit is set to 1 while the corresponding PID bits are set to BUF, this module completes the control transfer stage. Specifically, during control read transfer, this module transmits the ACK handshake in response to the OUT transaction from the USB host, and outputs the zero-length packet in response to the IN transaction from the USB host during control write or no-data control transfer. However, on detecting the SET_ADDRESS request, this module operates in auto response mode from the setup stage up to the status stage completion irrespective of the setting of this bit. This module modifies this bit from 1 to 0 on receiving the new setup packet. A 1 cannot be written to this bit while VALID is 1. When the host controller function is selected, be sure to write 0 to this bit.

When the pertinent pipe is in the transmitting direction (DIR = 1), this module sets this bit to 1 when at least one FIFO buffer plane of data has been written. This module sets this bit to 0 when this module completes transmitting the data from the FIFO buffer plane to which all the data has been written. In double buffer mode (DBLB = 1), this module sets this bit to 0 when this module completes transmitting the data from the two FIFO buffer planes before one FIFO buffer plane of data has been written. This bit indicates the same value as the BSTS bit when the pertinent pipe is in the receiving direction (DIR = 0).

For the transfer using the split transaction, to restart the next transfer with the S-SPLIT forcibly, set this bit to 1. However, for the normal split transaction, this module automatically clears the CSSTS bit to 0 upon completion of the C-SPLIT; therefore, clearing the CSSTS bit is not necessary. Controlling the CSSTS bit through this bit must be done while UACT is 0 and thus communication is halted or while no transfer is being performed with bus disconnection detected. Setting this bit to 1 while CSSTS is 0 has no effect. When the function controller function is selected, be sure to write 0 to this bit. 12 CSSTS 0 R CSSTS Status Bit Indicates the C-SPLIT status of the split transaction when the host controller function is selected. 0: START-SPLIT (S-SPLIT) transaction being processed or the transfer not using the split transaction in progress 1: C-SPLIT transaction being processed This module sets this bit to 1 upon start of the CSPLIT and clears this bit to 0 upon detection of CSPLIT completion. If the USB device is detached when processing of a C-SPLIT transaction is in progress, the CSSTS bit may remain set to 1. In such a case (DTCH = 1 detected), use the CSCLR bit to clear the CSSTS bit to 0. Indicates the valid value only when the host controller function is selected. 11 0 R Reserved This bit is always read as 0. The write value should always be 0.

When this bit is set to 1, this module responds to the token from the USB host as described below. (1) When the pertinent pipe is for bulk IN transfer (TYPE = 01 and DIR = 1) When ATREPM = 1 and PID = BUF, this module transmits a zero-length packet in response to the IN token. This module updates (allows toggling of) the sequence toggle bit (DATA-PID) each time this module receives the ACK from the USB host (in a single transaction, IN token is received, zerolength packet is transmitted, and then ACK is received.). In this case, this module does not generate the BRDY or BEMP interrupt. (2) When the pertinent pipe is for bulk OUT transfer (TYPE = 01 and DIR = 0) When ATREPM = 1 and PID = BUF, this module returns NAK in response to the OUT (or PING) token and generates the NRDY interrupt. Modify this bit while CSSTS is 0 and PID is NAK. Before modifying this bit after modifying the PID bits for the corresponding pipe from BUF to NAK, check that CSSTS and PBUSY are 0. However, if the PID bits have been modified to NAK by this module, checking PBUSY is not necessary.

Do not write to the FIFO buffer during USB communication in auto response mode. When the pertinent pipe is for isochronous transfer, be sure to set this bit to 0. When the host controller function is selected, set this bit to 0. 9 ACLRM 0 R/W Auto Buffer Clear Mode Enables or disables automatic buffer clear mode for the pertinent pipe. 0: Disabled 1: Enabled (all buffers are initialized) To delete all the information assigned to the pertinent pipe from the FIFO buffer, write 1 and 0 in succession to the ACLRM bit. Table 29.11 (1) lists the information related to the USB 2.0 host/function module that is cleared by setting the ACLRM bit to 1 and then to 0 in succession. Table 29.11 (2) lists the cases in which it is necessary to do this. Modify this bit while CSSTS is 0, PID is NAK, and the pertinent pipe is not specified in the CURPIPE bits. Before modifying this bit after modifying the PID bits for the corresponding pipe from BUF to NAK, check that CSSTS and PBUSY are 0. However, if the PID bits have been modified to NAK by this module, checking PBUSY is not necessary.

Setting this bit to 1 allows this module to set DATA0 as the expected value of the sequence toggle bit of the pertinent pipe. This module always sets this bit to 0. When the host controller function is selected, setting this bit to 1 for the pipe for bulk OUT transfer, this module starts the next transfer of the pertinent pipe with the PING token. Set the SQCLR bit to 1 while CSSTS is 0 and PID is NAK. Before modifying this bit after modifying the PID bits for the corresponding pipe from BUF to NAK, check that CSSTS and PBUSY are 0. However, if the PID bits have been modified to NAK by this module, checking PBUSY is not necessary.

Setting this bit to 1 allows this module to set DATA1 as the expected value of the sequence toggle bit of the pertinent pipe. This module always sets this bit to 0. Set the SQSET bit to 1 while CSSTS is 0 and PID is NAK. Before modifying this bit after modifying the PID bits for the corresponding pipe from BUF to NAK, check that CSSTS and PBUSY are 0. However, if the PID bits have been modified to NAK by this module, checking PBUSY is not necessary. 6 SQMON 0 R Toggle Bit Confirmation Indicates the expected value of the sequence toggle bit for the next transaction of the pertinent pipe. 0: DATA0 1: DATA1 When the pertinent pipe is not for the isochronous transfer, this module allows this bit to toggle upon normal completion of the transaction. However, this bit is not allowed to toggle when a DATA-PID disagreement occurs during the receiving transfer.

The USB 2.0 host/function module switches the PBUSY bit from 0 to 1 when a USB transaction using the pertinent pipe starts. It clears the PBUSY bit from 1 to 0 when one transaction completes successfully. Reading this bit after PID has been set to NAK allows checking that modification of the pipe settings is possible. For details, refer to section 29.4.3 (1), Pipe Control Register Switching Procedures. 4 to 2 All 0 R Reserved These bits are always read as 0. The write value should always be 0.

Modify the setting to BUF to use the pertinent pipe for USB transfer. Tables 29.12 and 29.13 show the basic operation (operation when there are no errors in the transmitted and received packets) of this module depending on the PID bit setting. After modifying the setting of these bits from BUF to NAK during USB communication using the pertinent pipe, check that PBUSY is 0 to see if USB communication using the pertinent pipe has actually entered the NAK state. However, if the PID bits have been modified to NAK by this module, checking PBUSY is not necessary. After S-SPLIT is issued (CSSTS = 1) for split transaction in the pertinent pipe, the transaction continues until C-SPLIT is completed even when the PID bits are set to NAK. This module modifies the setting of these bits as follows.

(1) Resets Table 29.15 lists the types of controller resets. For the initialized states of the registers following the reset operations, see section 29.3, Register Description. Table 29.15 Types of Reset Name Operation Power-on reset Low level input from the RES pin USB bus reset Automatically detected by this module from the D+ and D- lines when the function controller function is selected (2) Controller Function Selection This module can select the host controller function or function controller function using the DCFM bit in SYSCFG. Changing the DCFM bit should be done in the initial settings immediately after a power-on reset or in the D+ pull-up disabled (DPRPU = 0) and D + /D - pull-down disabled (DRPD = 0) state. (3) Enabling High-Speed Operation This module can select a USB communication speed (communication bit rate). When the host controller function is selected, the high-speed operation or full-speed/low-speed operation can be set. When the function controller function is selected, either the high-speed operation or full-speed operation can be selected. In order to enable the high-speed operation for this module, the HSE bit in SYSCFG should be set to 1. If high-speed mode has been enabled, this module executes the reset handshake protocol, and the USB communication speed is set automatically. The results of the reset handshake can be confirmed using the RHST bit in DVSTCTR. If high-speed operation has been disabled, this module operates at full-speed or low-speed. If the function controller function is also selected, this module operates at full-speed. Changing the HSE bit should be done between the ATTCH interrupt detection and bus reset execution when the host controller function is selected, or with the D+ line pull-up disabled (DPRPU = 0) when the host controller function is selected.

This module incorporates a pull-up resistor for the D+ signal and a pull-down resistor for the D+ and D- signals. These signals can be pulled up or down using the DPRPU and DRPD bits in SYSCFG. This module controls the terminal resistor for the D+ and D- signals during high-speed operation and the output resistor for the signals during full-speed operation. This module automatically switches the resistor after connection with the host controller or peripheral device by means of reset handshake, suspended state and resume detection. When the function controller function is selected and the DPRPU bit in SYSCFG is cleared to 0 during communication with the host controller, the pull-up resistor (or the terminal resistor) of the USB data line is disabled, making it possible to notify the USB host of the device disconnection.

Wait-related restriction: The cycle time for successive accesses to the USB 2.0 host/function module must be a duration of at least four USB clock (48 MHz) cycles (83.33 ns). To fulfill the above restriction, a register access wait control is necessary using the BWAIT[3:0] bits in BUSWAIT. The initial value is the maximum value (access cycles = 17 clock cycles). The optimum value should be found and set. Setting example 1: When successively accessing the registers of this module Peripheral clock 1 frequency: 66.67 MHz Calculation: (2 cycles (access cycles for the registers of this module) + 1 cycle (interval between successive accesses) + BWAIT) x 1/66.67 MHz 83.33 ns BWAIT = 3 Setting example 2: When sending data from the on-chip high-speed RAM to the FIFO port register through DMA transfer Peripheral clock 1 frequency: 66.67 MHz Calculation: (2 cycles (access cycles for the registers of this module) + 2 cycles (access cycles for the on-chip high-speed RAM) + BWAIT) x 1/66.67 MHz 83.33 ns BWAIT = 2 (6) Input Clock Selection The UCKPSEL and UCKFSEL bits in SYSCFG can be used to select the input pin from USB_X1 or EXTAL and the input clock frequency from 48 MHz or 12 MHz for this module. Stop supply of the clock signal to the USB module (SCKE = 0) when the UCKPSEL and UCKFSEL bits are to be modified. (7) Settings for Clock Supply to the USB Module The method of setting to select the clock signal for supply to the USB module depends on the input clock frequency.

The 48-MHz input can only be selected when the clock input pin USB_X1 has been set. (b) Selecting the 12-MHz Clock Input Set the UCKFSEL bit in SYSCFG to 1 and select the clock input pin by the UCKPSEL bit, then make settings for supply of the clock signal according to the following procedure. Setting example 1: When supply of the clock signal is enabled in the initial settings immediately after a power-on reset. l. Set the UPLLE bit to 1. 2. Wait for 1 ms. 3. Set the SCKE bit to 1. Setting example 2: When supply of the clock signal is stopped in the suspended state. 1. Set the SCKE bit to 0. 2. Set the UPLLE bit to 0. Setting example 3: When supplying the clock signal is enabled through recovery from the suspended state 1. Set the UPLLE bit to 1. 2. Wait for 1 ms. 3. Set the SCKE bit to 1. Note: If a USB reset is used for recovery from the suspended state when operation as a function controller and high-speed transfer is selected, set the SCKE bit to 1 in no more than 2.5 ms.

The following shows the conditions under which this module sets 1 to a corresponding bit in BRDYSTS. Under this condition, this module generates BRDY interrupt, if the PIPEBRDYE bit in BRDYENB that corresponds to the pipe to 1 and the BRDYE bit in INTENB0 have been set to 1. The conditions for generating and clearing the BRDY interrupt depend on the settings of the BRDYM bit and BFRE bit for the pertinent pipe as described below. (a) When the BRDYM bit is 0 and BFRE bit is 0 With these settings, the BRDY interrupt indicates that the FIFO port is accessible. On any of the following conditions, this module generates the internal BRDY interrupt request trigger and sets 1 to the PIPEBRDY bit corresponding to the pertinent pipe. (i) For the pipe in the transmitting direction: When the DIR bit is changed from 0 to 1. When packet transmission is completed using the pertinent pipe when write-access from the CPU to the FIFO buffer for the pertinent pipe is disabled (when the BSTS bit is read as 0). In continuous transmission/reception mode, the request trigger is generated on completion of transmitting data of one plane of the FIFO buffer. When one FIFO buffer is empty on completion of writing data to the other FIFO buffer in double buffer mode. The request trigger is not generated until completion of writing data to the currently-written FIFO buffer plane even if transmission to the other FIFO buffer is completed. When the hardware flushes the buffer of the pipe for isochronous transfers. When 1 is written to the ACLRM bit, which causes the FIFO buffer to make transition from the write-disabled to write-enabled state. The request trigger is not generated for the DCP (that is, during data transmission for control transfers). R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1647 of 3088 Section 29 USB 2.0 Host/Function Module (ii) SH7268 Group, SH7269 Group For the pipe in the receiving direction: When packet reception is completed successfully thus enabling the FIFO buffer to be read when read-access from the CPU to the FIFO buffer for the pertinent pipe is disabled (when the BSTS bit is read as 0). The request trigger is not generated for the transaction in which DATA-PID disagreement occurs. In continuous transmission/reception mode, the request trigger is not generated when the data is of the specified maximum packet size and the buffer has available space. When a short packet is received, the request trigger is generated even if the FIFO buffer has available space. When the transaction counter is used, the request trigger is generated on receiving the specified number of packets. In this case, the request trigger is generated even if the FIFO buffer has available space. When one FIFO buffer is read-enabled on completion of reading data from the other FIFO buffer in double buffer mode. The request trigger is not generated until completion of reading data from the currentlyread FIFO buffer plane even if reception by the other FIFO buffer is completed. When the function controller function is selected, the BRDY interrupt is not generated in the status stage of control transfers. The PIPEBRDY interrupt status of the pertinent pipe can be cleared to 0 by writing 0 to the corresponding PIPEBRDY interrupt status bit in the BRDYSTS register. In this case, 1s should be written to the PIPEBRDY interrupt status bits for the other pipes. Be sure to clear the BRDY status before accessing the FIFO buffer. Page 1648 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (b) Section 29 USB 2.0 Host/Function Module When the BRDYM bit is 0 and the BFRE bit is 1 With these settings, this module generates the BRDY interrupt on completion of reading all the data for a single transfer using the pipe in the receiving direction, and sets 1 to the PIPEBRDY bit corresponding to the pertinent pipe. On any of the following conditions, this module determines that the last data for a single transfer has been received. * When a short packet including a zero-length packet is received. * When the transaction counter register (TRNCNT bits) is used and the number of packets specified by the TRNCNT bits are completely received. When the pertinent data is completely read out after any of the above determination conditions has been satisfied, this module determines that all the data for a single transfer has been completely read out. When a zero-length packet is received while the FIFO buffer is empty, the USB 2.0 host/function module determines that all the data for a single transfer has been read at the point at which the FRDY bit is set to 1 and the DTLN bit cleared to 0 in the FIFO port control register. In this case, to start the next transfer, write 1 to the BCLR bit in the corresponding FIFOCTR register. With these settings, this module does not detect the BRDY interrupt for the pipe in the transmitting direction. The PIPEBRDY interrupt status of the pertinent pipe can be cleared to 0 by writing 0 to the corresponding PIPEBRDY interrupt status bit. In this case, 1s should be written to the PIPEBRDY interrupt status bits for the other pipes. In this mode, the BFRE bit setting should not be modified until all the data for a single transfer has been processed. When it is necessary to modify the BFRE bit before completion of processing, all the FIFO buffers for the pertinent pipe should be cleared using the ACLRM bit.

In other words, the BRDY interrupt status bits (PIPEBRDY) are set to 1 or 0 by this module depending on the FIFO buffer status. (i) For the pipe in the transmitting direction: The BRDY interrupt status bits are set to 1 when the FIFO buffer is write-enabled and are set to 0 when write-disabled. However, the BRDY interrupt is not generated if the DCP in the transmitting direction is writeenabled. (ii) For the pipe in the receiving direction: The BRDY interrupt status bits are set to 1 when the FIFO buffer is read-enabled and are set to 0 when all the data have been read (read-disabled). When a zero-length packet is received when the FIFO buffer is empty, the pertinent bit is set to 1 and the BRDY interrupt is continuously generated until BCLR = 1 is written. With this setting, the PIPEBRDY bit cannot be cleared to 0. When BRDYM is set to 1, all of the BFRE bits (for all pipes) should be cleared to 0.

If the corresponding bit in NRDYENB is set to 1, this module sets the NRDY bit in INTSTS0 to 1, allowing the USB interrupt to be generated. The following describes the conditions on which this module generates the internal NRDY interrupt request for a given pipe. However, the internal NRDY interrupt request is not generated during setup transaction execution when the host controller function is selected. During setup transactions when the host controller function is selected, the SACK or SIGN interrupt is detected. The internal NRDY interrupt request is not generated during status stage execution of the control transfer when the function controller function is selected. (a) (i) When the host controller function is selected and when the connection is used in which no split transactions occur For the pipe in the transmitting direction: On any of the following conditions, this module detects the NRDY interrupt. For the pipe for isochronous transfers, when the time to issue an OUT token comes in a state in which there is no data to be transmitted in the FIFO buffer. In this case, this module transmits a zero-length packet following the OUT token, setting the corresponding PIPENRDY bit and the OVRN bit to 1. During communications other than setup transactions using the pipe for the transfers other than isochronous transfers, when any combination of the following two cases occur three consecutive times: 1) no response is returned from the peripheral device (when timeout is detected before detection of the handshake packet from the peripheral device) and 2) an error is detected in the packet from the peripheral device.

If the corresponding bit in BEMPENB is set to 1, this module sets the BEMP bit in INTSTS0 to 1, allowing the USB interrupt to be generated. The following describes the conditions on which this module generates the internal BEMP interrupt request. (a) For the pipe in the transmitting direction, when the FIFO buffer of the corresponding pipe is empty on completion of transmission (including zero-length packet transmission). In single buffer mode, the internal BEMP interrupt request is generated simultaneously with the BRDY interrupt for the pipe other than DCP. However, the internal BEMP interrupt request is not generated on any of the following conditions. When writing data to the FIFO buffer of the CPU has already been started on completion of transmitting data of one plane in double buffer mode. When the buffer is cleared (emptied) by setting the ACLRM or BCLR bit to 1. When IN transfer (zero-length packet transmission) is performed during the control transfer status stage in function controller mode. (b) For the pipe in the receiving direction: When the successfully-received data packet size exceeds the specified maximum packet size. In this case, this module generates the BEMP interrupt request, setting the corresponding PIPEBEMP bit to 1, and discards the received data and modifies the setting of the PID bits of the corresponding pipe to STALL (11). Here, this module returns no response when used as the host controller, and returns STALL response when used as the function controller. However, the internal BEMP interrupt request is not generated on any of the following conditions. When a CRC error or bit stuffing error is detected in the received data. When a setup transaction is being performed. Writing 0 to the PIPEBEMP bit clears the status; writing 1 to the PIPEBEMP bit has no effect.

This module controls device states and generates device state transition interrupts. However, recovery from the suspended state (resume signal detection) is detected by means of the resume interrupt. The device state transition interrupts can be enabled or disabled individually using INTENB0. The device state that made a transition can be confirmed using the DVSQ bit in INTSTS0. To make a transition to the default state, the device state transition interrupt is generated after the reset handshake protocol has been completed. Device state can be controlled only when the function controller function is selected. Also, the device state transition interrupts can be generated only when the function controller function is selected.

This module controls the control transfer sequence and generates control transfer stage transition interrupts. Control transfer stage transition interrupts can be enabled or disabled individually using INTENB0. The transfer stage that made a transition can be confirmed using the CTSQ bit in INTSTS0. The control transfer stage transition interrupts are generated only when the function controller function is selected. The control transfer sequence errors are described below. If an error occurs, the PID bit in DCPCTR is set to B'1x (STALL). (a) During control read transfers At the IN token of the data stage, an OUT or PING token is received when there have been no data transfers at all. An IN token is received at the status stage A packet is received at the status stage for which the data packet is DATAPID = DATA0 (b) During control write transfers At the OUT token of the data stage, an IN token is received when there have been no ACK response at all A packet is received at the data stage for which the first data packet is DATAPID = DATA0 At the status stage, an OUT or PING token is received (c) During no-data control transfers At the status stage, an OUT or PING token is received At the control write transfer stage, if the number of receive data exceeds the wLength value of the USB request, it cannot be recognized as a control transfer sequence error. At the control read transfer status stage, packets other than zero-length packets are received by an ACK response and the transfer ends normally. When a CTRT interrupt occurs in response to a sequence error, the CTSQ = 110 value is retained until CTRT = 0 is written from the system (the interrupt status is cleared). Therefore, while CTSQ = 110 is being held, the CTRT interrupt that ends the setup stage will not be generated even if a new USB request is received. (The USB 2.0 host/function module retains the setting of the CTSQ R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1661 of 3088 SH7268 Group, SH7269 Group Section 29 USB 2.0 Host/Function Module bits when the setup stage ends, and it generates a CTRT interrupt after the interrupt status is cleared.)

With the host controller function selected, an interrupt is generated at the timing at which the frame number is updated. With the function controller function selected, the SOFR interrupt is generated when the frame number is updated. When the function controller function is selected, this module updates the frame number and generates an SOFR interrupt if it detects a new SOF packet during full-speed operation. During high-speed operation, however, this module does not update the frame number, or generates no SOFR interrupt until the module enters the SOF locked state. Also, the SOF interpolation function is not activated. The SOF lock state is the state in which SOF packets with different frame numbers are received twice continuously without error occurrence. The conditions under which the SOF lock monitoring begins and stops are as follows.

The level of the VBUS pin can be checked with the VBSTS bit in INTSTS0. Whether the host controller is connected or disconnected can be confirmed using the VBUS interrupt. However, if the system is activated with the host controller connected, the first VBUS interrupt is not generated because there is no change in the VBUS pin. (8) Resume Interrupt With the function controller function selected, the resume interrupt is generated when the USB bus state changes (from J-state to K-state, or from J-state to SE0) while the device state is the suspended state.. Recovery from the suspended state is detected by means of the resume interrupt. With the host controller function selected, the resume interrupt is not generated; use the BCHG interrupt to detect the change of the USB bus state. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1663 of 3088 Section 29 USB 2.0 Host/Function Module (9) SH7268 Group, SH7269 Group BCHG Interrupt The BCHG interrupt is generated when the USB bus state has changed. The BCHG interrupt can be used to detect whether or not the peripheral device is connected when the host controller function has been selected and can also be used to detect a remote wakeup. The BCHG interrupt is generated regardless of whether the host controller function or function controller function has been selected. (10) DTCH Interrupt The DTCH interrupt is generated if disconnection of the USB bus is detected when the host controller function has been selected. This module detects bus disconnection based on USB Specification 2.0. After detecting the DTCH interrupt, this module controls hardware as described below (irrespective of the set value of the corresponding interrupt enable bit). Terminate all the pipes in which communications are currently carried out for the USB port and make a transition to the wait state for bus connection to the USB port (wait state for ATTCH interrupt generation). (a) Modifies the UACT bit to 0. (b) Puts the port into the idle state. (11) SACK Interrupt The SACK interrupt is generated when an ACK response for the transmitted setup packet has been received from the peripheral device with the host controller function selected. The SACK interrupt can be used to confirm that the setup transaction has been completed successfully. (12) SIGN Interrupt The SIGN interrupt is generated when an ACK response for the transmitted setup packet has not been correctly received from the peripheral device three consecutive times with the host controller function selected. The SIGN interrupt can be used to detect no ACK response transmitted from the peripheral device or corruption of an ACK packet.

To be more specific, the ATTCH interrupt is detected on any of the following conditions. (a) When K-state, SE0, or SE1 changes to J-state, and J-state continues 2.5 s. (b) When J-state, SE0, or SE1 changes to K-state, and K-state continues 2.5 s. (14) EOFERR Interrupt The EOFERR interrupt is generated when it is detected that communication is not completed at the EOF2 timing prescribed by USB Specification 2.0. After detecting the EOFERR interrupt, this module controls hardware as described below (irrespective of the set value of the corresponding interrupt enable bit). Terminate all the pipes in which communications are currently carried out for the pertinent port and perform re-enumeration of the pertinent port. (a) Modifies the UACT bit for the port in which an EOFERR interrupt has been detected to 0. (b) Puts the port in which an EOFERR interrupt has been generated into the idle state. 29.4.3 Pipe Control Table 29.17 lists the pipe setting items of this module. With USB data transfer, data transmission has to be carried out using the logic pipe called the endpoint. This module has ten pipes that are used for data transfer. Settings should be entered for each of the pipes in conjunction with the specifications of the system.

PIPE1 and PIPE2: Set a value between 1 and 1023 when using full-speed isochronous transfer. 7. PIPE6 to PIPE9: Set a value between 1 and 64. The high bandwidth transfers used with interrupt transfers and isochronous transfers are not supported. (5) Transaction Counter (For PIPE1 to PIPE5 in Reading Direction) When the specified number of transactions have been completed in the data packet receiving direction, this module recognizes that the transfer has ended. The transaction counter function is available when the pipes assigned to the D0FIFO/D1FIFO port have been set in the direction of reading data from the buffer memory. Two transaction counters are provided: one is the TRNCNT register that specifies the number of transactions to be executed and the other is the current counter that internally counts the number of executed transactions. When the current counter value matches the number of the transactions specified in TRNCNT, reading the buffer memory is enabled. The current counter of the transaction counter function is initialized by the TRCLR bit, so that the transactions can be counted again starting from the beginning. The information read from TRNCNT differs depending on the setting of the TRENB bit. * TRENB = 0: The specified transaction counter value can be read. * TRENB = 1: The current counter value indicating the internally counted number of executed transactions can be read. When operating the TRCLR bit, the following should be noted. * If the transactions are being counted and PID = BUF, the current counter cannot be cleared. * If there is any data left in the buffer, the current counter cannot be cleared.

The following shows this module operation with various response PID settings: (a) Response PID settings when the host controller function is selected The response PID is used to specify the execution of transactions. * NAK setting: Using pipes is disabled. No transaction is executed. * BUF setting: Transactions are executed based on the status of the buffer memory. For OUT direction: If there are transmit data in the buffer memory, an OUT token is issued. For IN direction: If there is an area to receive data in the buffer memory, an IN token is issued. * STALL setting: Using pipes is disabled. No transaction is executed. Setup transactions for the DCP are set with the SUREQ bit. (b) Response PID settings when the function controller function is selected The response PID is used to specify the response to transactions from the host. * NAK setting: The NAK response is always returned in response to the generated transaction. * BUF setting: Responses are made to transactions based on the status of the buffer memory. * STALL setting: The STALL response is always returned in response to the generated transaction. For setup transactions, an ACK response is always returned, regardless of the PID setting, and the USB request is stored in the register. This module may carry out writing to the PID bits, depending on the results of the transaction. (a) When the host controller function has been selected and the response PID is set by hardware * NAK setting: In the following cases, PID = NAK is set and issuing of tokens is automatically stopped: When, during a transfer other than isochronous transfer, three receive errors such as no response, bit stuffing error, or CRC error are returned in succession after token transmission. When, during isochronous transfer, three receive errors such bit stuffing error or CRC error are returned in succession after token transmission.

If a short packet is received when the SHTNAK bit in PIPECFG has been set to 1 for bulk transfer. If the transaction counter ended when the SHTNAK bit has been set to 1 for bulk transfer. * BUF setting: There is no BUF writing by this module. * STALL setting: In the following cases, PID = STALL is set and issuing of tokens is automatically stopped: When STALL is received in response to the transmitted token. When the size of the receive data packet exceeds the maximum packet size. (b) When the function controller function has been selected and the response PID is set by hardware * NAK setting: In the following cases, PID = NAK is set and NAK is always returned in response to transactions: When the SETUP token is received normally (DCP only). If the transaction counter ended or a short packet is received when the SHTNAK bit in PIPECFG has been set to 1 for bulk transfer. * BUF setting: There is no BUF writing by this module. * STALL setting: In the following cases, PID = STALL is set and STALL is always returned in response to transactions: When the size of the receive data packet exceeds the maximum packet size. When a control transfer sequence error has been detected (DCP only). Page 1672 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (7) Section 29 USB 2.0 Host/Function Module Data PID Sequence Bit This module automatically toggles the sequence bit in the data PID when data is transferred normally in the control transfer data stage, bulk transfer and interrupt transfer. The sequence bit of the data PID that was transmitted can be confirmed with the SQMON bit in DCPCTR and PIPEnCTR. When data is transmitted, the sequence bit switches at the timing at which the ACK handshake is received. When data is received, the sequence bit switches at the timing at which the ACK handshake is transmitted. The SQCLR bit in DCPCTR and the SQSET bit in PIPEnCTR can be used to change the data PID sequence bit. When the function controller function has been selected and control transfer is used, this module automatically sets the sequence bit when a stage transition is made. The bit is set to DATA1 when the setup stage ends. In the status stage, DATA1 is returned without referencing the sequence bit. Therefore, settings are not required. However, when the host controller function has been selected and control transfer is used, the sequence bit should be set at the stage transition. For the Clearfeature request transmission or reception, the data PID sequence bit should be set, regardless of whether the host controller function or function controller function is selected. With pipes for which isochronous transfer has been set, sequence bit operation cannot be carried out using the SQSET bit. (8) Response PID = NAK Function This module has a function that disables pipe operation (PID response = NAK) at the timing at which the final data packet of a transaction is received (this module automatically distinguishes this based on reception of a short packet or the transaction counter) by setting the SHTNAK bit in PIPECFG to 1. When a double buffer is being used for the buffer memory, using this function enables reception of data packets in transfer units. If pipe operation has disabled, the pipe has to be set to the enabled state again (PID response = BUF). This function can be used only when bulk transfers are used. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1673 of 3088 Section 29 USB 2.0 Host/Function Module (9) SH7268 Group, SH7269 Group Auto Transfer MODE With the pipes for bulk transfer (PIPE1 to PIPE5), when the ATREPM bit in PIPEnCTR is set to 1, a transition is made to auto response mode. During an OUT transfer (DIR = 0), OUT-NAK mode is entered, and during an IN transfer (DIR = 1), null auto response mode is entered. (a) OUT-NAK Mode With the pipes for bulk OUT transfer, NAK is returned in response to an OUT or PING token and an NRDY interrupt is output when the ATREPM bit is set to 1. To make a transition from normal mode to OUT-NAK mode, OUT-NAK mode should be specified in the pipe operation disabled state (response PID = NAK) before enabling pipe operation (response PID = BUF). After pipe operation has been enabled, OUT-NAK mode becomes valid. However, if an OUT token is received immediately before pipe operation is disabled, the token data is normally received, and an ACK is retuned to the host. To make a transition from OUT-NAK mode to normal mode, OUT-NAK mode should be canceled in the pipe operation disabled state (response PID = NAK) before enabling pipe operation (response PID = BUF). In normal mode, reception of OUT data is enabled and an ACK is returned in response to a PING token if the buffer is ready to receive data. (b) Null Auto Response Mode With the pipes for bulk IN transfer, zero-length packets are continuously transmitted when the ATREPM bit is set to 1. To make a transition from normal mode to null auto response mode, null auto response mode should be set in the pipe operation disabled state (response PID = NAK) before enabling pipe operation (response PID = BUF). After pipe operation has been enabled, null auto response mode becomes valid. Before setting null auto response mode, INBUFM = 0 should be confirmed because the mode can be set only when the buffer is empty. If the INBUFM bit is 1, the buffer should be emptied with the ACLRM bit. While a transition to null auto response mode is being made, data should not be written from the FIFO port. To make a transition from null auto response mode to normal mode, pipe operation disabled state (response PID = NAK) should be retained for the period of zero-length packet transmission (fullspeed: 10 s, high-speed: 3 s) before canceling null auto response mode. In normal mode, data can be written from the FIFO port; therefore, packet transmission to the host is enabled by enabling pipe operation (response PID = BUF).

The FIFO buffer memory is an area shared by the CPU and this module. In the FIFO buffer memory status, there are times when the access right to the buffer memory is allocated to the user system (CPU side), and times when it is allocated to this module (SIE side). The buffer memory sets independent areas for each pipe. In the memory areas, 64 bytes comprise one block, and the memory areas are set using the first block number of the number of blocks (specified using the BUFNMB and BUFSIZE bits in PIPEBUF). Independent buffer memory areas should be set for each pipe. Each memory area can be set using the first block number and the number of blocks (specified using the BUFNMB and BUFSIZE bits in PIPEBUF), where one block comprises 64 bytes. When continuous transfer mode has been selected using the CNTMD bit in PIPEnCFG, the BUFSIZE bits should be set so that the buffer memory size should be an integral multiple of the maximum packet size. When double buffer mode has been selected using the DBLB bit in PIPEnCFG, two planes of the memory area specified using the BUFSIZE bits in PIPEBUF can be assigned to a single pipe. Moreover, three FIFO ports are used for access to the buffer memory (reading and writing data). A pipe is assigned to the FIFO port by specifying the pipe number using the CURPIPE bit in C/DnFIFOSEL. The buffer statuses of the various pipes can be confirmed using the BSTS bit in DCPCTR and the INBUFM bit in PIPEnCTR. Also, the access right of the FIFO port can be confirmed using the FRDY bit in CFIFOCTR or DnFIFOCTR.

Figure 29.9 Example of a Buffer Memory Map (a) Buffer Status Tables 29.18 and 29.19 show the buffer status. The buffer memory status can be confirmed using the BSTS bit in DCPCTR and the INBUFM bit in PIPEnCTR. The access direction for the buffer memory can be specified using either the DIR bit in PIPEnCFG or the ISEL bit in CFIFOSEL (when DCP is selected). The INBUFM bit is valid for PIPE0 to PIPE5 in the sending direction. For an IN pipe uses double buffer, the BSTS bit can be used to monitor the buffer memory status of CPU side and the INBUFM bit to monitor the buffer memory status of SIE side. In the case like the BEMP interrupt may not shows the buffer empty status because the CPU (direct memory access controller) writes data slowly, the INBUFM bit can be used to confirm the end of sending.

The buffer memory can be cleared using the three bits indicated below. Table 29.20 List of Buffer Clearing Methods Bit Name BCLR DCLRM ACLRM Register CFIFOCTR DnFIFOSEL PIPEnCTR DnFIFOCTR Function Clears the buffer memory on the CPU side In this mode, after the data of the specified pipe has been read, the buffer memory is cleared automatically. This is the auto buffer clear mode, in which all of the received packets are discarded. Clearing method Cleared by writing 1 1: Mode valid 1: Mode valid 0: Mode invalid 0: Mode invalid (c) Buffer Areas Table 29.21 shows the FIFO buffer memory map of this controller. The buffer memory has special fixed areas to which pipes are assigned in advance, and user areas that can be set by the user. The buffer for the DCP is a special fixed area that is used both for control read transfers and control write transfers. The PIPE6 to PIPE9 area is assigned in advance, but the area for pipes that are not being used can be assigned to PIPE1 to PIPE5 as a user area. The settings should ensure that the various pipes do not overlap. Note that each area is twice as large as the setting value in the double buffer. Also, the buffer size should not be specified using a value that is less than the maximum packet size.

If a normal data packet has been received, the ACK response is returned to the host controller. This function can be set only in the buffer memory reading direction. Also, if the ACLRM bit is set to 1 and then to 0, the buffer memory of the selected pipe can be cleared regardless of the access direction. (e) Buffer Memory Specifications (Single/Double Setting) Either a single or double buffer can be selected for PIPE1 to PIPE5, using the DBLB bit in PIPEnCFG. The double buffer is a function that assigns two memory areas specified with the BUFSIZE bit in PIPEBUF to the same pipe. Figure 29.10 shows an example of buffer memory settings for this module. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1679 of 3088 SH7268 Group, SH7269 Group Section 29 USB 2.0 Host/Function Module Buffer memory PIPEBUF registers 64 bytes BUFSIZE = 0, DBLB = 0 64 bytes 64 bytes BUFSIZE = 0, DBLB = 1 128 bytes BUFSIZE = 1, DBLB = 0 Figure 29.10 Example of Buffer Memory Settings (f) Buffer Memory Operation (Continuous Transfer Setting) Either the continuous transfer mode or the non-continuous transfer mode can be selected, using the CNTMD bit in PIPEnCFG. This selection is valid for PIPE1 to PIPE5. The continuous transfer mode function is a function that sends and receives multiple transactions in succession. When the continuous transfer mode is set, data can be transferred without interrupts being issued to the CPU, up to the buffer sizes assigned for each of the pipes. In the continuous sending mode, the data being written is divided into packets of the maximum packet size and sent. If the data being sent is less than the buffer size (short packet, or the integer multiple of the maximum packet size is less than the buffer size), BVAL = 1 must be set after the data being sent has been written. In the continuous reception mode, interrupts are not issued during reception of packets up to the buffer size, until the transaction counter has ended, or a short packet is received. Table 29.22 describes the relationship between the transfer mode settings by CNTMD bit and the timings at which reading data or transmitting data from the FIFO buffer is enabled.

Continuous transfer (CNTMD = 1) In the receiving direction (DIR = 0), reading data from the FIFO buffer is enabled when: * The number of the data bytes received in the FIFO buffer assigned to the selected pipe becomes the same as the number of assigned data bytes ((BUFSIZE + 1) x 64). * This module receives a short packet other than a zero-length packet. * This module receives a zero-length packet when data is already stored in the FIFO buffer assigned to the selected pipe. or * This module receives the number of packets equal to the transaction counter value specified for the selected pipe. In the transmitting direction (DIR = 1), transmitting data from the FIFO buffer is enabled when: R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 * The number of the data bytes written to the FIFO buffer becomes the same as the number of data bytes in a single FIFO buffer plane assigned to the selected pipe. or * The number of data bytes less than the size of a single FIFO buffer plane (including 0-byte data) assigned to the selected pipe is written to the FIFO buffer and then 1 is written to BVAL. * A number of data bytes less than the size of a single FIFO buffer plane assigned to the selected pipe is written to the FIFO buffer and the DMA transfer end signal is received when the last byte is written.

In write access, writing data until the buffer is full (or the maximum packet size for non-continuous transfers) automatically enables sending of the data. To enable sending of data before the buffer is full (or before the maximum packet size for non-continuous transfers), the BVAL bit in C/DnFIFOCTR must be set to end the writing. Also, to send a zero-length packet, the BCLR bit in the same register must be used to clear the buffer and then the BVAL bit set in order to end the writing. In read access, reception of new packets is automatically enabled if all of the data has been read. Data cannot be read when a zero-length packet is being received (DTLN = 0), so the BCLR bit in the register must be used to release the buffer. The length of the data being received can be confirmed using the DTLN bit in C/DnFIFOCTR.

The pipe to be accessed is selected using the CURPIPE bit in C/DnFIFOSEL. After the pipe is selected, whether the CURPIPE value for the pipe, which was written last, can be correctly read should be checked. (If the previous pipe number is read, it indicates that the pipe modification is being executed by this module.) Then, the FIFO port can be accessed after FRDY = 1 is checked . Also, the bus width to be accessed should be selected using the MBW bit. The buffer memory access direction conforms to the DIR bit in PIPEnCFG. The ISEL bit determines this only for the DCP.

The REW bit in C/DnFIFOSEL is used for this. If a pipe is selected when the REW bit is set to 1 and at the same time the CURPIPE bit in C/DnFIFOSEL is set, the pointer used for reading from and writing to the buffer memory is reset, and reading or writing can be carried out from the first byte. Also, if a pipe is selected with 0 set for the REW bit, data can be read and written in continuation of the previous selection, without the pointer used for reading from and writing to the buffer memory being reset. To access the FIFO port, FRDY = 1 must be ensured after selecting a pipe. (c) Accessing FIFO Port for Odd Data For reading data from the FIFO port, when the number of data bits to be read is smaller than the access width specified by the MBW bits in the FIFO port select registers, read the data with the specified width and discard the unnecessary bits through software. For writing data to the FIFO port, when the number of data bits to be written is smaller than the access width specified by the MBW bits in the FIFO port select registers, access the registers as shown in the following examples. In the examples, the FIFO port access width is 32 bits (MBW = 10) and 24-bit data is written to the FIFO port.

When the DCP is currently set (CURPIPE = 000) in the CFIFO port select register, modify the MBW bits simultaneously with the CURPIPE bits or ISEL bit. To modify only the MBW bits for the currently set pipe, follow the procedure below. Once the buffer memory starts to be read out, however, do not modify the MBW bits until the entire data has been read out. When the selected CURPIPE is in the writing direction to buffer memory, the port access width can be changed simply by setting the MBW bits. Once the buffer memory starts to be written to, however, do not modify the port access width from 8 bits to 16 or 32 bits, or from16 bits to 32 bits.

When accessing the buffer for the pipe targeted for DMA transfer is enabled, a DMA transfer request is issued. The unit of transfer to the FIFO port should be selected using the MBW bit in DnFIFOSEL and the pipe targeted for the DMA transfer should be selected using the CURPIPE bit. The selected pipe should not be changed during the DMA transfer. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1687 of 3088 SH7268 Group, SH7269 Group Section 29 USB 2.0 Host/Function Module (b) Auto Recognition of DMA Transfer Completion With this module, it is possible to complete FIFO data writing through DMA transfer by controlling DMA transfer end signal input. The DMA transfer end signal is output from the direct memory access controller when the controller transfers data through DMA for the times specified by the DMA transfer count register (DMATCR) of the direct memory access controller. When a transfer end signal is sampled, the module enables buffer memory transmission (the same condition as when BVAL = 1). Whether to sample the DMA transfer end signal can be specified through the TENDE bit in DnFBCFG. Note that this function cannot be used when the DMA transfer size is set to 16 bytes. (c) DnFIFO Auto Clear Mode (D0FIFO/D1FIFO Port Reading Direction) If 1 is set for the DCLRM bit in DnFIFOSEL, the module automatically clears the buffer memory of the selected pipe when reading of the data from the buffer memory has been completed. Table 29.25 shows the packet reception and buffer memory clearing processing for each of the various settings. As shown, the buffer clear conditions depend on the value set to the BFRE bit. Using the DCLRM bit eliminates the need for the buffer to be cleared even if a situation occurs that necessitates clearing of the buffer. This makes it possible to carry out DMA transfers without involving software. This function can be set only in the buffer memory reading direction.

The DCP buffer memory is a 256-byte single buffer, and is a fixed area that is shared for both control reading and control writing. The buffer memory can be accessed through the CFIFO port. (1) Control Transfers when the Host Controller Function is Selected (a) Setup Stage USQREQ, USBVAL, USBINDX, and USBLENG are the registers that are used to transmit a USB request for setup transactions. Writing setup packet data to the registers and writing 1 to the SUREQ bit in DCPCTR transmits the specified data for setup transactions. Upon completion of transactions, the SUREQ bit is cleared to 0. The above USB request registers should not be modified while SUREQ = 1. The device address for setup transactions is specified using the DEVSEL bits in DCPMAXP. When the data for setup transactions has been sent, a SIGN or SACK interrupt request is generated according to the response received from the peripheral device (SIGN1 or SACK bits in INTSTS1), by means of which the result of the setup transactions can be confirmed. A data packet of DATA0 (USB request) is transmitted as the data packet for the setup transactions regardless of the setting of the SQMON bit in DCPCTR. (b) Data Stage Data transfers are done using the DCP buffer memory. The access direction of the DCP buffer memory should be specified using the ISEL bit in CFIFOSEL. Also specify the transfer direction using the DIR bit in the DCPCFG register. For the first data packet of the data stage, the data PID must be transferred as DATA1. Transaction is done by setting the data PID = DATA1 and the PID bit = BUF using the SQSET bit in DCPCTR. Completion of data transfer is detected using the BRDY or BEMP interrupts. Setting continuous transfer mode allows data transfers over multiple packets. Note that when continuous transfer mode is set for the receiving direction, the BRDY interrupt is not generated until the buffer becomes full or a short packet is received (the integer multiple of the maximum packet size, and less than 256 bytes). For control write transfers, when the number of data bytes to be sent is the integer multiple of the maximum packet size, a zero-length packet must be controlled to be sent at the end. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1689 of 3088 Section 29 USB 2.0 Host/Function Module (c) SH7268 Group, SH7269 Group Status Stage Zero-length packet data transfers are done in the direction opposite to that in the data stage. As with the data stage, data transfers are done using the DCP buffer memory. Transactions are done in the same manner as the data stage. For the data packets of the status stage, the data PID must be transferred as DATA1. The data PID should be set to DATA1 using the SQSET bit in DCPCTR. For reception of a zero-length packet, the received data length must be confirmed using the DTLN bits in CFIFOCTR after the BRDY interrupt is generated, and the buffer memory must then be cleared using the BCLR bit. (2) Control Transfers when the Function Controller Function is Selected (a) Setup Stage This module always sends an ACK response in response to a setup packet that is normal with respect to this module. The operation of this module operates in the setup stage is noted below. (i) When a new USB request is received, this module sets the following registers: * Set the VALID bit in INTSTS0 to 1. * Set the PID bit in DCPCTR to NAK. * Set the CCPL bit in DCPCTR to 0. (ii) When a data packet is received right after the SETUP packet, the USB request parameters are stored in USBREQ, USBVAL, USBINDX, and USBLENG. Response processing with respect to the control transfer should always be carried out after first setting VALID = 0. In the VALID = 1 state, PID = BUF cannot be set, and the data stage cannot be terminated. Using the function of the VALID bit, this module is able to interrupt the processing of a request currently being processed if a new USB request is received during a control transfer, and can send a response in response to the newest request. Also, this module automatically judges the direction bit (bit 8 of the bmRequestType) and the request data length (wLength) of the USB request that was received, and then distinguishes between control read transfers, control write transfers, and no-data control transfers, and controls the stage transition. For a wrong sequence, the sequence error of the control transfer stage transition interrupt is generated, and the software is notified. For information on the stage control of this module, see figure 29.7. Page 1690 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (b) Section 29 USB 2.0 Host/Function Module Data Stage Data transfers corresponding to USB requests that have been received should be done using the DCP. Before accessing the DCP buffer memory, the access direction should be specified using the ISEL bit in CFIFOSEL. A transaction is executed by setting the PID bits in the DCPCTR register to BUF. The BRDY interrupt or the BEMP interrupt can be used to detect the end of data transfer. Use the BRDY interrupt to detect the end of control write transfers and the BEMP interrupt to detect the end of control read transfers. If the data being transferred is larger than the size of the DCP buffer memory, the data transfer should be carried out using the BRDY interrupt for control write transfers and the BEMP interrupt for control read transfers. With control write transfers during high-speed operation, the NYET handshake response is carried out based on the state of the buffer memory. (c) Status Stage Control transfers are terminated by setting the CCPL bit to 1 with the PID bit in DCPCTR set to PID = BUF. After the above settings have been entered, this module automatically executes the status stage in accordance with the data transfer direction determined at the setup stage. The specific procedure is as follows. (i) For control read transfers: This module receives a zero-length packet from the USB host and sends an ACK response. (ii) For control write transfers and no-data control transfers: This module sends the zero-length packet from the USB host and receives an ACK response.

If any of the following errors occur in the SET_ADDRESS request, a response is necessary. (i) bmRequestType H'00 (ii) wIndex H'00 (ii) wLength H'00 (iv) wValue > H'7F (v) DVSQ = 011 (Configured) For all requests other than the SET_ADDRESS request, the corresponding response is required.

The maximum size that can be set for the buffer memory is 2 Kbytes. The buffer memory state is controlled by this module, with a response sent automatically for a PING packet/NYET handshake. (1) PING Packet Control when the Host Controller Function is Selected This module automatically sends a PING packet in the OUT direction. On receiving an ACK handshake in the initial state in which PING packet sending mode is set, this module sends an OUT packet as noted below. The module returns to PING packet sending mode when a NAK or NYET is received during an OUT transaction. 1. Sets OUT data sending mode. 2. Sends a PING packet. 3. Receives an ACK handshake. 4. Sends an OUT data packet. 5. Receives an ACK handshake. (Repeats steps 4 and 5.) 6. Sends an OUT data packet. 7. Receives an NAK/NYET handshake. 8. Sends a PING packet. This module is returned to PING packet sending mode by a power-on reset, receiving a NYET/NAK handshake, clearing the sequence toggle bits (SQCLR), and setting the buffer clear bit (ACLRM) in PIPEnCTR.

The USB 2.0 host/function module returns a NYET when an OUT token is received while there is only one packet of empty space in the buffer memory, during both bulk transmission and control transmission. However, an ACK is returned instead of a NYET even under the above conditions when a short packet is received.

When an OUT token is received, there is only enough space in the buffer memory for one packet. When a PING token is received, there is no space in the buffer memory. When an IN token is received, there is data to be sent in the buffer memory. When an IN token is received, there is no data to be sent in the buffer memory. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 29.4.7 Section 29 USB 2.0 Host/Function Module Interrupt Transfers (PIPE6 to PIPE9) When the function controller function is selected, this module carries out interrupt transfers in accordance with the timing controlled by the host controller. For interrupt transfers, PING packets are ignored (no responses are sent), and the ACK, NAK, and STALL responses are carried out without an NYET handshake response being made. When the host controller function is selected, this module can set the timing of issuing a token using the interval timer. At this time, this module issues an OUT token even in the OUT direction, without issuing a PING token. This module does not support high bandwidth transfers of interrupt transfers. (1) Interval Counter during Interrupt Transfers when the Host Controller Function is Selected For interrupt transfers, intervals between transactions are set in the IITV bits in PIPEPERI. This controller issues an interrupt transfer token based on the specified intervals. (a) Counter Initialization This controller initializes the interval counter under the following conditions. * Power-on reset The IITV bits are initialized. * Buffer memory initialization using the ACLRM bit The IITV bits are not initialized but the count value is. Setting the ACLRM bit to 0 starts counting from the value set in the IITV bits. Note that the interval counter is not initialized in the following case. * USB bus reset, USB suspended The IITV bits are not initialized. Setting 1 to the UACT bit starts counting from the value before entering the USB bus reset state or USB suspended state.

In such a case, this module attempts transactions at the subsequent interval. * When the PID is set to NAK or STALL. * When the buffer memory is full at the token sending timing in the receiving (IN) direction. * When there is no data to be sent in the buffer memory at the token sending timing in the sending (OUT) direction. 29.4.8 Isochronous Transfers (PIPE1 and PIPE2) This module has the following functions pertaining to isochronous transfers. 1. Notification of isochronous transfer error information 2. Interval counter (specified by the IITV bit) 3. Isochronous IN transfer data setup control (IDLY function) 4. Isochronous IN transfer buffer flush function (specified by the IFIS bit) This module does not support the High Bandwidth transfers of isochronous transfers. When using more than one pipe simultaneously for isochronous transfers, follow the packet constraints provided in section 5.6.3, Isochronous Transfer Packet Size Constraints, in Universal Serial Bus Revision 2.0 Specification. (1) Error Detection with Isochronous Transfers This module has a function for detecting the error information noted below, so that when errors occur in isochronous transfers, software can control them. Tables 29.27 and 29.28 show the priority in which errors are confirmed and the interrupts that are generated. (a) PID errors * If the PID of the packet being received is illegal (b) CRC errors and bit stuffing errors * If an error occurs in the CRC of the packet being received, or the bit stuffing is illegal (c) Maximum packet size exceeded * The maximum packet size exceeded the set value.

When using isochronous OUT transfers (transmission), the OUT token was transmitted, but the data was not in the buffer memory. * When function controller function is selected: When using isochronous IN transfers (transmission), the IN token was received but the data was not in the buffer memory. When using isochronous OUT transfers (reception), the OUT token was received, but the buffer memory was not empty. (e) Interval errors When function controller function is selected, the following cases are considered as interval errors: * During an isochronous IN transfer, the token could not be received during the interval frame. * During an isochronous OUT transfer, the OUT token was received during frames other than the interval frame.

When the host controller function is selected, no tokens are transmitted. When the function controller function is selected, a zero-length packet is transmitted in response to IN token. However, no data packets are received in response to OUT token. 4 Interval errors An NRDY interrupt is generated when the function controller function is selected. It is not generated when the host controller function is selected.

The interval counter enables the functions shown in table 29.29 when the function controller function is selected. When the host controller function is selected, this module generates the token issuance timing. When the host controller function is selected, the interval counter operation is the same as the interrupt transfer operation. Table 29.29 Functions of the Interval Counter when the Function Controller Function is Selected Transfer Direction Function Conditions for Detection IN IN buffer flush function When an IN token cannot be normally received in the interval frame during an isochronous IN transfer OUT Notifies that a token not being received When an OUT token cannot be normally received in the interval frame during an isochronous OUT transfer The interval count is carried out when an SOF is received or for interpolated SOFs, so the isochronisms can be maintained even if an SOF is damaged. The frame interval that can be set is IITV IITV the 2 frame or 2 frames. (a) Interval Counter Initialization when the Function Controller Function is Selected This module initializes the interval counter under the following conditions. * Power-on reset The IITV bit is initialized. * Buffer memory initialization using the ACLRM bit The IITV bits are not initialized but the count value is. * USB bus reset After the interval counter has been initialized, the counter is started under the following conditions 1 or 2 when a packet has been transferred normally. 1. An SOF is received following transmission of data in response to an IN token, in the PID = BUF state. 2. An SOF is received after data following an OUT token is received in the PID = BUF state.

When the PID bit is set to NAK or STALL The interval timer does not stop. This module attempts the transactions at the subsequent interval. 2. The USB bus reset or the USB is suspended The IITV bit is not initialized. When the SOF has been received, the counter is restarted from the value prior to the reception of the SOF. (b) Interval Counting and Transfer Control when the Host Controller Function is Selected This module controls the interval between token issuance operations based on the IITV bit IITV settings. Specifically, this module issues a token for a selected pipe once every 2 () frames. This module counts the interval every 1-ms frame for the pipes used for communications with the full-speed or low-speed peripheral devices connected to a high-speed HUB. This module starts counting the token issuance interval at the () frame following the () frame in which the PID bits have been set to BUF.

This module issues a token even when the NRDY interrupt generation condition is satisfied. * When the selected pipe is for isochronous IN transfers This module generates the NRDY interrupt when this module issues the IN token but does not receive a packet successfully from a peripheral device (no response or packet error). This module sets the OVRN bit to 1 generating the NRDY interrupt when the time to issue an IN token comes in a state in which this module cannot receive data because the FIFO buffer is full (because data is read from the FIFO buffer too late). * When the selected pipe is for isochronous OUT transfers This module sets the OVRN bit to 1 generating the NRDY interrupt and transmitting a zerolength packet when the time to issue an OUT token comes in a state in which there is no data to be transmitted in the FIFO buffer (because data is written to the FIFO buffer too late ). The token issuance interval is reset when a power-on reset is applied or the ACLRM bit is set to 1.

This module generates the NRDY interrupt when this module fails to receive a data packet because of a CRC error or other errors contained in the packet, or because of the FIFO buffer being full. This module generates the NRDY interrupt on receiving an SOF packet. Even if the SOF packet is corrupted, the internal interpolation is used and allows the interrupt to be generated at the timing to receive the SOF packet. However, when the IITV bits are set to the value other than 0, this module generates the NRDY interrupt on receiving an SOF packet for every interval after starting interval counting operation. When the PID bits are set to NAK after starting the interval timer, this module does not generate the NRDY interrupt on receiving an SOF packet. The interval counting starts at the different timing depending on the IITV bit setting as follows. When IITV = 0: The interval counting starts at the () frame following the () frame in which the PID bits for the selected pipe has been set to BUF.

When IFIS = 0, this module transmits a data packet in response to the received IN token irrespective of the IITV bit setting. When IFIS = 1, this module clears the FIFO buffer when this module fails to receive an IN token within the interval set by the IITV bits in terms of () frames in a state in which there is data to be transmitted in the FIFO buffer. This module also clears the FIFO buffer when this module fails to receive an IN token successfully because of a bus error such as a CRC error contained in the token. This module clears the FIFO buffer on receiving an SOF packet. Even if the SOF packet is corrupted, the internal interpolation is used and allows the FIFO buffer to be cleared at the timing to receive the SOF packet. The interval counting starts at the different timing depending on the IITV bit setting (similar to the timing during OUT transfers). The interval count clearing condition is any of the following in function controller mode. When a power-on reset is applied. When the ACLRM bit is set to 1. When this module detects a USB bus reset.

This function is called the isochronous transfer transmission data setup function, and it makes it possible to designate the frame from which transmission began. If a double buffer is used for the buffer memory, transmission will be enabled for only one of the two buffers even after the writing of data to both buffers has been completed, that buffer memory being the one to which the data writing was completed first. For this reason, even if multiple IN tokens are received, the only buffer memory that can be sent is one packet's worth of data. When an IN token is received, if the buffer memory is in the transmission enabled state, this module transmits the data. If the buffer memory is not in the transmission enabled state, however, a zero-length packet is sent and an underrun error occurs. Figure 29.20 shows an example of transmission using the isochronous transfer transmission data setup function with this module, when IITV = 0 (every frame) has been set.

If a double buffer is being used and writing to both buffers has been completed, the buffer memory that was cleared is seen as the data having been sent at the same interval frame, and transmission is enabled for the buffer memory that is not discarded with SOF or SOF packets reception. Page 1706 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 29 USB 2.0 Host/Function Module The timing at which the operation of the buffer flush function varies depending on the value set for the IITV bit. * If IITV = 0 The buffer flush operation starts from the next frame after the pipe becomes valid. * In any cases other than IITV = 0 The buffer flush operation is carried out subsequent to the first normal transaction. Figure 29.21 shows an example of the buffer flush function of this module. When an unanticipated token is received prior to the interval frame, this module sends the written data or a zero-length packet according to the buffer state. SOF Buffer A Empty Writing Writing ended Transfer enabled Empty Writing Writing ended Buffer flush operation is carried out Buffer B Empty Writing Writing ended Transfer enabled Figure 29.21 Example of Buffer Flush Function Operation Figure 29.22 shows an example of this module generating an interval error. There are five types of interval errors, as shown below. The interval error is generated at the timing indicated by (1) in the figure, and the IN buffer flush function is activated. If an interval error occurs during an IN transfers, the buffer flush function is activated; and if it occurs during an OUT transfer, an NRDY interrupt is generated. The OVRN bit should be used to distinguish between NRDY interrupts such as received packet errors and overrun errors. In response to tokens that are shaded in the figure, responses occur based on the buffer memory status. 1. IN direction: If the buffer is in the transmission enabled state, the data is transferred as a normal response. If the buffer is in the transmission disabled state, a zero-length packet is sent and an underrun error occurs. 2.

The SOF interpolation operation begins when the USBE and SCKE bits in SYSCFG have been set to 1 and an SOF packet is received. The interpolation function is initialized under the following conditions. * Power-on reset * USB bus reset * Suspended state detected Also, the SOF interpolation operates under the following specifications. * 125 s/1 ms conforms to the results of the reset handshake protocol. * The interpolation function is not activated until an SOF packet is received. * After the first SOF packet is received, either 125 s or 1 ms is counted with an internal clock of 48 MHz, and interpolation is carried out. * After the second and subsequent SOF packets are received, interpolation is carried out at the previous reception interval. * Interpolation is not carried out in the suspended state or while a USB bus reset is being received. (With suspended transitions in high-speed operation, interpolation continues for 3 ms after the last packet is received.) This module supports the following functions based on the SOF detection. These functions also operate normally with SOF interpolation, if the SOF packet was corrupted.

If a SOF packet is missing during high-speed operation, the UFRNM bit in UFRMNUM is refreshed. However, if a SOF packet for which the UFRNM = 000 is missing, the FRNM bit is not refreshed. In this case, the FRNM bit is not refreshed even if successive SOF packets other than UFRNM = 000 are received normally. 29.4.10 Pipe Schedule (1) Conditions for Generating a Transaction When the host controller function is selected and UACT has been set to 1, this module generates a transaction under the conditions noted in table 29.30.

Symbols () in the table indicate that the condition is one that is unrelated to the generating of tokens. "Valid" indicates that, for interrupt transfers and isochronous transfers, the condition is generated only in transfer frames that are based on the interval counter. "Invalid" indicates that the condition is generated regardless of the interval counter. 2. This indicates that a transaction is generated regardless of whether or not there is a receive area. If there was no receive area, however, the received data is destroyed. 3. This indicates that a transaction is generated regardless of whether or not there is any data to be sent. If there was no data to be sent, however, a zero-length packet is sent. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1709 of 3088 Section 29 USB 2.0 Host/Function Module (2) SH7268 Group, SH7269 Group Transfer Schedule This section describes the transfer scheduling within a frame of this module. After the module sends an SOF, the transfer is carried out in the sequence described below. 1. Execution of periodic transfers A pipe is searched in the order of Pipe 1 Pipe 2 Pipe 6 Pipe 7 Pipe 8 Pipe 9, and then, if the pipe is one for which an isochronous or interrupt transfer transaction can be generated, the transaction is generated. 2. Setup transactions for control transfers The DCP is checked, and if a setup transaction is possible, it is sent. 3. Execution of bulk and control transfer data stages and status stages A pipe is searched in the order of DCP Pipe 1 Pipe 2 Pipe 3 Pipe 4 Pipe 5, and then, if the pipe is one for which a bulk or control transfer data stage or a control transfer status stage transaction can be generated, the transaction is generated. If a transfer is generated, processing moves to the next pipe transaction regardless of whether the response from the peripheral device is ACK or NAK. Also, if there is time for the transfer to be done within the frame, step 3 is repeated. (3) USB Communication Enabled Setting the UACT bit of the DVSTCTR register to 1 initiates sending of an SOF or SOF, and makes it possible to generate a transaction. Setting the UACT bit to 0 stops the sending of the SOF or SOF and initiates a suspend state. If the setting of the UACT bit is changed from 1 to 0, processing stops after the next SOF or SOF is sent.

If AGCLEVEL = 236 and AGCPRECIS = 10, AGC gain is fixed within the following range: (236 - 10) < Output sync signal amplitude < (236 + 10) In this case, the PGA gain can fall within a 2-step range. For video image with stabilized sync signal amplitude, AGCPRECIS = 4 is recommended, which enables the PGA gain to fall within a 1-step range, when the electric field is strong. For the above setting, the recommended value is 10 to avoid hunting in a weak electric field.

Supported color systems are NTSC, PAL, and SECAM. This module consists of an A/D converter for video signal input, sync separator circuit, burst controlled oscillator (BCO), a Y/C separator circuit, a chroma decoding circuit, a digital clamp circuit, and an output gain adjustment circuit. Figure 30.25 shows an overall block diagram. Figure 30.25 Overall Block Diagram (1) A/D Converter for Video Signal Input The A/D converter processes the composite video signal (CVBS) using the sync tip clamp block and the programmable gain amplifier (PGA) and A/D-converts the signal. The composite video signals from either VIN1 or VIN2 pin are selected. (2) Sync Separator Circuit The sync separator circuit extracts the horizontal and vertical sync signals from the composite video signal. This circuit also detects the amplitude of the sync signals and automatically adjusts the PGA gain (automatic gain control = AGC). R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1845 of 3088 Section 30 Digital Video Decoder (3) SH7268 Group, SH7269 Group Burst Controlled Oscillator (BCO) The BCO extracts the color burst signal from the composite video signal and reproduces the color sub-carrier signal required for color demodulation. The BCO also acquires phase and frequency information from the color burst signal and detects the color system used. (4) Y/C Separator Circuit The Y/C separator circuit separates the composite video signal of the NTSC, PAL, or SECAM format into the Y and C signals. Two-dimensional adaptive separation is used for NTSC and PAL and one-dimensional separation for SECAM. (5) Chroma Decoding Circuit The chroma decoding circuit demodulates the C signal extracted by the Y/C separator circuit into the Cb/Cr signal. This circuit has the automatic color control function (ACC), in which the amplitude of the color burst signal is detected to adjust the color gain automatically and also has the TINT/R-Y axis correction function, in which hue is adjusted at demodulation. (6) Digital Clamp Circuit The digital clamp circuit provides pedestal clamp for the Y signals and center clamp for the Cb/Cr signals at any position. This circuit also detects the amount of noise using the autocorrelation function. (7) Output Adjustment Circuit The output adjustment circuit sets the capturing position and adjusts the contrast and color.

(3) Programmable Gain Amplifier (PGA) The PGA adjusts the gain so that the input video signal voltage ( 0.8 Vpp to 1.6 Vpp) should be the level to be input to the A/D converter ( 2.0 Vpp). One of 32 levels of gain values can be set. One level corresponds to gain of 0.2 dB (typ.). The minimum gain is 1.835 dB (typ.) and maximum gain is 8.023 dB (typ.). Table 30.35 shows the PGA gain setting and gain values.

This circuit also detects the amplitude of the sync signals and automatically adjusts the PGA gain (automatic gain control = AGC). Figure 30.28 shows the block diagram of the sync separator circuit. Figure 30.28 Block Diagram of Sync Separator Circuit (1) Clipping Block The clipping block clips the high tone component of the video signal to reduce amplitudedependency of the video signal. The specific clipping level can be set using SYNSCR3.SSCLIPSEL[3:0]. The clipping level should be within the range so that the composite sync signal component should not be deteriorated (should be detectable). (2) Noise Reduction Low-Pass Filter (LPF) for Horizontal Sync The noise reduction LPF reduces the superimposed noise on the video signals before composite sync signal separation. The LPFs can be separately set for the horizontal sync and vertical sync. The cutoff frequency of the horizontal sync LPF can be set using SYNSCR1.LPFHSYNC[2:0]. The cutoff frequency should be within a range that assures that the composite sync signal components are not degraded (are detectable). (3) Noise Reduction Low-Pass Filter (LPF) for Vertical Sync The noise reduction LPF reduces the superimposed noise on the video signals before composite sync signal separation. The LPFs can be separately set for the horizontal sync and vertical sync. The cutoff frequency of the vertical sync LPF can be set using SYNCSCR1.LPFVSYNC[2:0]. The Page 1850 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder cutoff frequency should be within a range that assures that the composite sync signal components are not degraded (are detectable). (4) Composite Sync Separator for Horizontal Sync The composite sync separator separates the composite sync signal from the video signal according to the slice level. The composite sync slice levels can be separately set for the vertical and vertical sync signals. The slice level can be set either automatically or manually according to the SYNSCR1.SLICERMODE_H[1:0] setting. When automatic setting is used, the slice level is automatically set according to the SYNSCR1.SLICERMODE_H[1:0], SYNSCR2.SYNCMAXDUTY_H[5:0], and SYNSCR2.SYNCMINDUTY_H[5:0] setting. The slice level detection speed can be set using SYNSCR1.VELOCITYSHIFT_H[3:0]. When manual setting is used, the slice level is determined by SYNSCR3.CSYNCSLICE_H[9:0]. (5) Composite Sync Separator for Vertical Sync The composite sync separator separates the composite sync signal from the video signal according to the slice level. The composite sync slice levels can be separately set for the vertical and vertical sync signals. The slice level can be set either automatically or manually according to the SYNSCR1.SLICERMODE_V[1:0] setting. When automatic setting is used, the slice level is automatically set according to the SYNSCR1.SLICERMODE_V[1:0], SYNSCR4.SYNCMAXDUTY_H[5:0], and SYNSCR4.SYNCMINDUTY_H[5:0] setting. When manual setting is used, the slice level is determined by SYNSCR5.CSYNCSLICE_V[9:0]. (6) Vertical Sync Separator The vertical sync separator extracts the vertical sync signal from the composite video signal separated using (5) above. The threshold value for separating the vertical sync signal can be set using SYNSCR5.VSYNCSLICE[4:0]. The value should be set depending on the serration pulse width of each video signal format. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1851 of 3088 Section 30 Digital Video Decoder (7) SH7268 Group, SH7269 Group Horizontal Automatic Frequency Control (AFC) Block The horizontal AFC, which is a digital PLL, extracts the horizontal sync signal from the composite video signal separated using (4) above. The AFC removes the pseudo horizontal sync signal and interpolates the incomplete horizontal sync signal to generate a stable horizontal sync signal. The center frequency and lock range of the horizontal AFC can be set using HAFCCR1.HAFCTYP[9:0], HAFCCR2.HAFCMAX[9:0], and HAFCCR3.HAFCMIN[9:0]. If the horizontal AFC is locked, VSYNCSR.FHLOCK becomes 1; and if the horizontal AFC is unlocked, VSYNCSR.FHLOCK becomes 0. The horizontal AFC oscillation cycle can be checked by reading HSYNCSR.FHCOUNT[16:1] and VSYNCSR.FHCOUNT[0]. The loop gain (response speed) of the horizontal AFC can be set using HAFCCR1.HAFCCGAIN[3:0]. As the speed is increased, the lockup time becomes shorter. However, the horizontal oscillation frequency will be more susceptible to noise. With HAFCCR3.HAFCMODE[1], AFCPFCR.PHDET_FIX, and AFCPFCR.PHDET_DIV[2:0], the loop gain can be reduced when S/N is low to prevent malfunction attributed to noise. Whether S/N is low or not can be checked with VSYNCSR.ISNOISY. The loop gain during the vertical blanking period (VBI) can be set using HAFCCR2.HAFCSTART[3:0], HAFCCR3.HAFCEND[3:0], and HAFCCR3.HAFCMODE[0]. This is usually used to avoid malfunction in the VCR head switch. (8) Vertical Countdown Block The vertical countdown block removes the pseudo vertical sync signal from the vertical sync signal separated using (6) above and interpolates the incomplete vertical sync signal to generate a stable vertical sync signal. The oscillation cycle of the vertical countdown block can be set using VCDWCR1.VCDDEFAULT[1:0]. When set to 0, the input vertical sync signal is detected and the oscillation cycle is automatically set appropriately. The detection result of the input vertical sync signal is indicated by VSYNCSR.FVMODE. When set to 1, 50.00-Hz oscillation mode is set. Here, it is recommended to set VCDWCR1.NOVCD60 to 1 (60-Hz oscillation off) to avoid unexpected malfunction. When set to 2 or 3, 59.94-/60.00-Hz oscillation mode is set. Here, it is recommended to set VCDWCR1.NOVCD50 to 1 (50-Hz oscillation off) to avoid unexpected malfunction. The lock range of the vertical countdown block can be set using VCDWCR1.VCDWINDOW[5:0] and VCDWCR1.VCDOFFSET[4:0]. If the vertical countdown block is locked, VSYNCSR.FVLOCK becomes 1; and if the vertical countdown block is unlocked, VSYNCSR.FVLOCK becomes 0. Page 1852 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder The cycle of the input vertical sync signal can be checked by reading VSYNCSR.FVCOUNT[7:0]. When the vertical sync signal input cannot be detected, VSYNCSR.NOSIGNAL is set to 1. (9) Automatic Gain Control (AGC) Block with Peak Limiter The AGC block detects the amplitude of the sync signal and automatically controls the PGA gain to the target value. The AGC function is activated with ADCCR1.AGCMODE = 1. * Gain Control according to Sync Amplitude The target sync signal amplitude can be set using AGCCR1.AGCLEVEL[8:0] and AGCCR2.AGCPRECIS[5:0]. For example, when NTSC signals are quantized by the 10-bit A/D converter, the sync signal amplitude for the full range of the A/D converter can be provided by: 1023[LSB] x (40[IRE] / 173[IRE]) = 236.53179[LSB] Therefore, 236[LSB] should be set to AGCCR1.AGCLEVEL[8:0]. The gain is fixed when it falls within the following range. Target value (= AGCCR1.AGCLEVEL[8:0]) AGCCR2.AGCPRECISE[5:0] Whether the gain is fixed or not can be checked by reading AGCCR2.AGCCONVERGE. The detected sync signal amplitude can be checked using SYNCSSR.SYNCDEPTH[9:0]. The AGC response speed can be set using AGCCR1.AGCRESOPONSE[2:0]. As the speed is increased, the input signal is tracked more quickly; however, it will result in more susceptibleness to noise. The currently set gain value can be checked using AGCCSR2.AGCGAIN[7:0]. The actual PGA gain setting can be roughly calculated as follows: 0.585776 x (AGCCSR2.AGCGAIN[7:0] - 49) For example, when AGCCSR2.AGCGAIN[7:0] is 64 (corresponding to x1), PGA gain setting = 0.585776 x (64 - 49) 8.78 As a result, the PGA gain setting is 8 or 9. One of 0 to 31 can be set as the PGA gain value. The gain during vertical blanking period (VBI) can be set using AGCCR1.DOREDUCE and AGCCR1.NOREDUCE. The sync amplitude detection result during VBI can be read from SYNCSSR.ISREDUCED. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1853 of 3088 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder * Peak Limiter The peak limiter works when the ratio of the video signal amplitude to the sync signal amplitude is inappropriate. If the ratio is smaller than expected, the PGA gain becomes smaller, and the video signal after gain adjustment becomes smaller than the full range of the A/D converter. Contrarily, if the ratio is larger than expected, the PGA gain becomes larger, and the video signal after gain adjustment becomes larger than the full range of the A/D converter. 1023 [LSB] Smaller than the full range Video signal Ratio of video signal amplitude amplitude to sync signal amplitude is small 236 [LSB] Sync signal Gain adjustment amplitude 0 [LSB] Input video Output signal Overflow 1023 [LSB] Video signal amplitude Ratio of video signal amplitude to sync signal amplitude is large 236 [LSB] Sync signal Gain adjustment amplitude 0 [LSB] Input video Output signal Figure 30.29 Cases in which Ratio of Video Signal Amplitude to Sync Signal Amplitude is Inappropriate To deal with this problem, the peak limiter adjusts the PGA gain based on the sampled video signal peak value. The peak value used to control the gain can be set using PKLIMITCR.PEAKLEVEL[1:0]. When the peak value of the sampled video signal is smaller than the value set using PKLIMITCR.PEAKLEVEL[1:0], the gain is increased. Contrarily, when the peak value of the sampled video signal is larger than the value set using PKLIMITCR.PEAKLEVEL[1:0] exceeding the maximum allowable value set using PKLIMITCR.MAXPEAKSAMPLES[7:0], the gain is decreased. Page 1854 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder The gain increase/decrease response speed and maximum compression ratio can be set using PKLIMITCR.PEAKATTACK[1:0], PKLIMITCR.PEAKRELEASE[1:0], and PKLIMITCR.PEAKRATIO[1:0]. The number of pixels with the peak value larger than the value set using PKLIMITCR.PEAKLEVEL[1:0] can be checked with AGCCSR1.HIGHSAMPLES[7:0]; and the number of overflowing pixels (exceeding 1023[LSB]) can be checked with AGCCSR1.PEAKSAMPLES[7:0]. * Manual Setting Manual setting of the PGA gain can be enabled by setting PGACR.PGA_GAIN_SEL to 1. Here, the value set using PGACR.PGA_GAIN[4:0] is actually set as the PGA gain. When PGACR.PGA_GAIN_SEL is 1, ADCCR1.AGCMODE setting is invalid. Setting PGACR.PGA_GAIN_SEL to 0 (automatic setting) and ADCCR1.AGCMODE to 0 (AGC off) simultaneously is prohibited. (10) Timing Adjustment and Signal Detection Block The timing adjustment and signal detection block adjusts the output timing of the horizontal and vertical sync signals generated using (7) and (8) above. This block also detects the field; whether the interlaced or progressive system is used can be checked with VSYNCSR.INTERLACED. If the field detection function is unstable, setting SYNSCR5.VSYNCDELAY to 1 may improve the function. 30.5.4 Burst Controlled Oscillator (BCO) The BCO extracts the color burst signal from the composite video signal and reproduces the color sub-carrier signal required for color demodulation. It also acquires the phase and frequency information from the color burst signal and detects the color system used. Figure 30.30 shows the block diagram of the BCO. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1855 of 3088 Section 30 Digital Video Decoder SH7268 Group, SH7269 Group Figure 30.30 Block Diagram of Burst Controlled Oscillator (1) Color Burst Extraction Block The color burst extraction block extracts the color burst signal. The position of the color burst signal to be extracted can be adjusted using BTGPCR.BGPWIDTH[6:0] and BTGPCR.BGPSTART[7:0]. The extraction result of the color burst signal can be checked by reading CROMASR1.NOBURST. (2) Color Burst Adjustment Block The color burst adjustment block adjusts the amplitude of the extracted color burst signal. For details, refer to section 30.5.6 (1), Automatic Color Control (ACC) Block. This block also outputs the signal to turn on or off the color killer according to the amplitude of the input color burst signal. For details, refer to section 30.5.6 (2), Color Killer. (3) Burst Lock PLL The burst lock PLL is a digital PLL which reproduces the color sub-carrier signal from the adjusted color signal. The lock range of the burst lock PLL can be set using BTLCR.LOCKRANGE[1:0]. If the burst lock PLL is locked, CROMASR1.FSCLOCK becomes 1; and if unlocked, CROMASR1.FSCLOCK becomes 0. The loop gain of the burst lock PLL can be set using BTLCR.LOOPGAIN[1:0] and BTLCR.LOCKLIMIT[1:0]. As the response speed is increased and the frequency search is started earlier, the lockup time becomes shorter. However, the PLL becomes unstable and unlocked more easily due to noise. The S/N of the color burst signal can be checked using CROMASR2.LOCKLEVEL[7:0]. Page 1856 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (4) Section 30 Digital Video Decoder Color System Detection Block The color system detection block detects the color system of the input video signal based on the oscillation frequency of the burst lock PLL and phase information of the color burst signal. The color system can be detected using BTLCR.NONTSC358, BTLCR.NONTSC443, BTLCR.NOPALM, BTLCR.NOPALN, BTLCR.NOPAL443, and BTLCR.NOSECAM. Color system detection can be set to fully automatic, manual, or semi-automatic (detecting the specified color system only). If the detection result does not apply to any color system type, the color system selected with BTLCR.DEFAULTSYS[1:0] is assumed. When an NTSC, PAL, or SECAM signal is detected, 1 is read from CROMASR2.ISNTSC, CROMASR2.ISPAL, or CROMASR2.ISSEAM, respectively. The currently used color system can be checked by reading CROMASR1.COLORSYS[1:0]. The color sub-carrier frequency can be checked by reading CROMASR1.FSCMODE. 30.5.5 Y/C Separator Circuit The Y/C separator circuit separates the composite video signal of the NTSC, PAL, or SECAM format into the Y and C signals. Two-dimensional adaptive separation is used for NTSC and PAL and one-dimensional separation for SECAM. Figure 30.31 shows a block diagram of the Y/C separator circuit. Figure 30.31 Block Diagram of Y/C Separator Circuit R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1857 of 3088 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder Table 30.36 shows the operation of the Y/C separator circuit for each color format.

This block delays video signals to hold three lines of data. (2) Horizontal and Vertical Filter Block In two-dimensional adaptive Y/C separation, the horizontal band pass filter (BPF), vertical band pass filter (BPF), and horizontal/vertical band pass filter (BPF) are adaptively switched according to the correlation between the horizontally-/vertically-adjacent pixels. This block processes the input signals using the horizontal BPF, vertical BPF, or horizontal/vertical BPF. In onedimensional Y/C separation, only the horizontal BPF is used. Figure 30.32 shows the filter configuration. Page 1858 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder Horizontal BPF HBPF1_9TAP_ON 17TAP BPF HBPF_NARROW 0 0 Output from HBPF filter 9TAP BPF 1 17TAP BPF 1 Output from H17TAP filter Output from H9TAP filter Horizontal/ vertical BPF Upper line Middle line Lower line Vertical BPF Output from VBPF filter HVBPF1_9TAP_ON HVBPF_NARROW 17TAP BPF 0 9TAP BPF 1 0 Output from HVBPF filter 17TAP BPF 1 Output from HV17TAP filter Output from HV9TAP filter Figure 30.32 Horizontal and Vertical Filter Configuration The horizontal BPF is composed of two stages. Either the 9-TAP or 17-TAP BPF is selected at the former stage. When YCSCR8.HBPF1_9TAP_ON/HVBPF1_9TAP_ON is 0, the 17-TAP BPF is selected; and when 1, the 9-TAP BPF is selected. Either bypass operation or the 9-TAP BPF is selected at the latter stage. When YCSCR8.HBPF_NARROW/HVBPF_ NARROW is 0, bypass operation is selected; and when 1, the 17-TAP BPF is selected. (3) Horizontal and Vertical Correlation Detection Block The horizontal and vertical correlation detection block detects the correlation value between the horizontal pixels, vertical pixels, and horizontal/vertical pixels. The value obtained by mixing the detected correlation value and the two-dimensional Y/C separation filter select coefficient is used for selecting the appropriate horizontal, vertical, or horizontal/vertical filter. Table 30.37 shows the two-dimensional Y/C separation filter select coefficients.

R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (4) Section 30 Digital Video Decoder Correlation Detection Filter Block The correlation detection filter block, specific to this module, attaches greater importance to the correlation between lines to reduce dot crawl, especially at the intersection of a cross. By mixing the signals after correlation detection filter block, dot crawl can be reduced when dot crawl is not fully removed by the horizontal and vertical filter block. (5) Horizontal and Vertical Signal Mixing Block The horizontal and vertical signal mixing block mixes the signals output from the horizontal, vertical, and horizontal/vertical filter blocks with the signals output from the horizontal and horizontal/vertical filters of the former stage. After that, the appropriate signal is selected from among the signals output from the horizontal, vertical, and horizontal/vertical filters according to the correlation value obtained using (3). Figure 30.33 shows the configuration of the horizontal and vertical signal mixing block. Figure 30.33 Configuration of Horizontal and Vertical Signal Mixing Block The signal to be mixed, which is output from either the horizontal or horizontal/vertical filter of the former stage, can be selected with YCSCR8.HFIL_TAP_SEL. When YCSCR8. HFIL_TAP_SEL is 0, the signal output from the 17-TAP filter is selected; and when 1, the signal output from the 9-TAP filter is selected. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1861 of 3088 Section 30 Digital Video Decoder SH7268 Group, SH7269 Group This block mixes the signals output from the horizontal filter with the signals output from the above described horizontal filter of the former stage. The mixing ratio can be set with YCSCR9.HSEL_MIX_Y[3:0]. Similarly, this block mixes the signals output from the vertical or horizontal/vertical filter with the signals output from the above described horizontal/vertical filter of the former stage. The mixing ratio can be set with YCSCR9.VSEL_MIX_Y[3:0] and YCSCR9.HVSEL_MIX_Y[3:0]. This block selects the appropriate signal from among the signals output from the horizontal, vertical, and horizontal/vertical filters according to the correlation value obtained using (3). (6) Correlation Detection Value Mixing Block The correlation detection value mixing block mixes the C signal for Y generation, and the C signal generated using (5) with the signals after correlation detection filter block (4). Figure 30.34 shows the configuration of the correlation detection value mixing block. Figure 30.34 Configuration of Correlation Detection Value Mixing Block When YCSCR9.DET2_ON is 1, this block mixes the signal after the correlation detection filter block. The mixing ratio of the C signal for Y generation to the signal after the correlation detection filter block can be set with YCSCR12.DET2_MIX_Y[3:0]. Similarly, the mixing ratio of the C signal to the signal after the correlation detection filter block can be set with YCSCR12.DET2_MIX_C[3:0]. When YCSCR9.DET2_ON is 0, this block outputs the signal after the horizontal and vertical filter block without mixing.

(8) Cascade Filter Block The cascade filter block allows the C signal to pass through the cascade filter or TAKE-OFF filter to further narrow the bandwidth. Figure 30.35 shows the configuration of the cascade filter block. Figure 30.35 Configuration of Cascade Filter Block The cascade filter block is composed of two stages. Either bypass operation or 17-TAP filter is selected at the former stage. Bypass operation, cascade, or TAKE-OFF filter can be selected at the former stage with YCSCR12.FIL2_MODE_2D[1:0]. Similarly, either bypass operation or 17-TAP filter can be selected at the latter stage with YCSCR12.FIL2_NARROW_2D. Both of the former- and latter-stage filters are universal and can be set with YCTWA_F0 to YCTWA_F8, YCTWB_F0 to YCTWB_F8, YCTNA_F0 to YCTNA_F8, and YCTNB_F0 to YCTNB_F8. Tables 30.38 to 30.40 show the recommended setting for each filter.

To reduce this phenomenon, the over-range control block automatically inserts the low-pass filter for Y signals (cuts off the frequency components of the vertical lines) Page 1866 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder Setting RGORCR7.UCMP_SW to 1 enables over-range control, and setting RGORCR7.DCMP_SW to 1 enables under-range control. One of four over-range levels can be set with RGORCR1.RADJ_O_LEVEL0[9:0], RGORCR3.RADJ_O_LEVEL1[9:0], and RGORCR5.RADJ_O_LEVEL2[9:0]. Similarly, one of four under-range levels can be set with RGORCR2.RADJ_U_LEVEL0[9:0], RGORCR4.RADJ_U_LEVEL1[9:0], and RGORCR6.RADJ_U_LEVEL2[9:0]. The filter to be inserted is appropriately selected according to the over-range and under-range levels. Setting HWIDE_SW to 1 enables detection of the maximum (minimum) level of five pixels in the horizontal direction in addition to the currently processed pixel to detect over-range or underrange occurrence. 30.5.6 Chroma Decoding Circuit The chroma decoding circuit demodulates the C signal extracted by the Y/C separator circuit into the Cb/Cr signal. This circuit has the automatic color control function (ACC), in which the amplitude of the color burst signal is detected to adjust the color gain automatically and also has the TINT/R-Y axis correction function, in which hue is adjusted at demodulation. Figure 30.36 shows the block diagram of the chroma decoding circuit.

The ACC function is activated with ACCCR1.ACCMODE = 0. The target amplitude of the color burst signal can be set with ACCCR1.ACCLEVEL[8:0]. The gain is fixed when the amplitude falls within ACCCR1.ACCLEVEL[8:0] ACCCR3.ACCPRECIS[5:0]. The maximum ACC gain can be set with ACCCR1.ACCMAXGAIN[1:0]. The currently set gain value can be checked by reading CROMASR1.ACCMAINGAIN[8:0] (main) and CROMASR1.ACCSUBGAIN[1:0] (sub). The C signal gain can also be set manually by setting ACCCR1.ACCMODE to 1. The specific gain value can be set with ACCCR2.CHROMAMAINGAIN[8:0] (main) and ACCCR2.CHROMASUBGAIN[1:0] (sub). (2) Color Killer The color killer deletes color information when the color bust signal amplitude is small in a weak electric field. The color killer is turned on or off based on the hysteresis; specifically, it is turned on when the amplitude reaches the value set with ACCCR3.KILLERLEVEL[5:0] and turned off when the amplitude reaches the value determined by ACCCR3.KILLERLEVEL[5:0] + ACCCR1.KILLEROFFSET[3:0]. The color killer can also be turned off forcibly by so setting ACCCR3.KILLERMODE. (3) Hue Adjustment Correction Block The hue adjustment correction block adjusts the color sub-carrier signal phase to adjust the Cb/Cr hue after chroma decoding. This function can be used only for the NTSC and PAL systems. The phase of the demodulation axis is controlled with TINTCR.TINTMAIN[9:0] and the phase of the R-Y axis is controlled with TINTCR.TINTSUB[5:0]. (4) Chroma Decoding Block The chroma decoding block demodulates the Cb/Cr signal from the C signal. Line averaging can be carried out before demodulation according to YCDCR.DEMODMODE[1:0] setting. YCDCR.DEMODMODE[1:0] should usually be set to 2 (two-line demodulation for PAL only; one-line demodulation for NTSC).

The Y signal can be delayed by -16 to 15 clock pulses with YCDCR.LUMADELAY[4:0]. (6) Frequency Band Inhibition LPF The frequency band inhibition LPF inhibits the frequency band of the Cb/Cr signal after chroma decoding. This LPF is turned on or off according to YCDCR.CHROMALPF setting. 30.5.7 Digital Clamp Circuit The digital clamp circuit provides pedestal clamp for the Y signals and center clamp for the Cb/Cr signals at any position. This circuit also detects the amount of noise using the autocorrelation function. Figure 30.37 shows the block diagram of the digital clamp circuit.

The setting is used in common to Y, Cb, and Cr signals. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1869 of 3088 Section 30 Digital Video Decoder (2) SH7268 Group, SH7269 Group Y Signal Horizontal Clamp Position Control Block The horizontal clamp start position of the Y signal can be set with DCPCR7.DCPPOS_Y[7:0]. The horizontal clamp width can be set with DCPCR6.DCPWIDTH[6:0]. The horizontal clamp width setting is used in common to Y, Cb, and Cr signals. (3) Cb/Cr Signal Horizontal Clamp Position Control Block The horizontal clamp start position of the Cb/Cr signal can be set with DCPCR8.DCPPOS_C[7:0]. The horizontal clamp width can be set with DCPCR6.DCPWIDTH[6:0]. The horizontal clamp width setting is used in common to Y, Cb, and Cr signals. (4) Pedestal Clamp Control Block The pedestal clamp control block stabilizes the Y signal pedestal level. When DCPCR1.DCPMODE_Y is 0, the value set with DCPCR1.BLANKLEVEL_Y[9:0] is subtracted from the Y signal, which is expressed as: Y signal output = Y signal input - DCPCR1.BLANKLEVEL_Y[9:0] When DCPCR1.DCPMODE_Y is 1, the Y signal level detected at the set clamp position and DCPCR1.BLANKLEVEL_Y[9:0] are added together and the resulting value is subtracted from the Y signal, which is expressed as: Y signal output = Y signal input - (detected value + DCPCR1.BLANKLEVEL_Y[9:0]) The detected value can be used from DSPCR1.CLAMPLEVEL_Y[9:0]. The clamp response speed can be set with DCPCR3.DCPRESPONSE[2:0]. The setting is used in common to Y, Cb, and Cr signals. (5) Center Clamp Control Block The center clamp control block stabilizes the Cb/Cr signal center level. When DCPCR2.DCPMODE_C is 0, the value set with DCPCR2.BLANKLEVEL_CB/DCPCR2.BLANKLEVEL_CR[5:0] is subtracted from the Cb/Cr signal, which is expressed as: Cb signal output = Cb signal input - DCPCR2.BLANKLEVEL_CB[5:0] Cr signal output = Cr signal input - DCPCR2.BLANKLEVEL_CR[5:0] Page 1870 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 30 Digital Video Decoder When DCPCR2.DCPMODE_C is 1, the Cb/Cr signal level detected at the set clamp position and DCPCR2.BLANKLEVEL_CB/DCPCR2.BLANKLEVEL_CR[5:0] are added together and the resulting value is subtracted from the Cb/Cr signal, which is expressed as: Cb signal output = Cb signal input - (detected value + DCPCR2.BLANKLEVEL_CB[5:0]) Cr signal output = Cr signal input - (detected value + DCPCR2.BLANKLEVEL_CR[5:0]) The detected value can be used from DSPCR1.CLAMPLEVEL_CB[5:0] and DSPCR2.CLAMPLEVEL_CR[5:0]. The clamp response speed can be set with DCPCR3.DCPRESPONSE[2:0]). The setting is used in common to Y, Cb, and Cr signals. (6) Noise Detection Block Using the autocorrelation function, the noise amount at the set clamp position can be detected. With NSDCR.ACFINPUT[1:0], either Y, Cb, or Cr signal can be selected for which to calculate the autocorrelation function. The delay time for autocorrelation function calculation can be set with NSDCR.ACFLAGTIME[4:0] and accumulated field amount of autocorrelation function can be set with NSDCR.ACFFILTER[1:0]. The autocorrelation function (correlation coefficient) can be read from NSDSR.ACFSTRENGTH[15:0]. 30.5.8 Output Control Circuit The output control circuit sets the signal capturing position and adjusts the contrast and color. Figure 30.38 shows the block diagram of the output control circuit Figure 30.38 Block Diagram of Output Control Circuit R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1871 of 3088 Section 30 Digital Video Decoder (1) SH7268 Group, SH7269 Group Capturing Position Setting Block The capturing position setting block sets the position to capture the input video signals. The position can be set with TGCR1.SRCLEFT[8:0], TGCR2.SRCTOP[5:0], TGCR2.SRCHEIGHT[9:0], and TGCR3.SRCWIDTH[10:0]. These settings are applied only to this module. To set the display size of the input video signals, the vertical capture size register (SCL0_DS2) and horizontal capture size register (SCL0_DS3) of the scaler of video display controller 4 should be used. (2) Contrast and Color Adjustment Block The contrast and color adjustment block adjusts the gain of the output Y/Cb/Cr signals. The contrast (Y signal gain) can be adjusted with YGAINCR.Y_GAIN2[9:0] and the color (Cb/Cr signal gain) can be adjusted with CBGAINCR.CB_GAIN2[9:0] and CRGAINCR.CR_GAIN2[9:0].

The video image clock is used while the video image is processed in the input controller, passed to the scale-down control block in the scaler, and then written to the buffer (internal bus write control). When the INP_SEL bit is 0 (video decoder output selected) in INP_SEL_CNT of the input controller, the VIDEO_X1 clock (27 MHz) is used as the video image clock. When INP_SEL is 1 (external input pin selected), the DV_CLK clock is used as the video image clock. The pixel clock is used in graphics read-out processing by the scaler (internal bus read controller) through output controller processing. When the parallel RGB output is selected in the output controller, the frequencies of the pixel clock and panel clock (LCD_CLK) are the same. The panel clock can be selected from the video image clock, LCD_EXTCLK, and peripheral bus clock 1 (P1) with the PANEL_ICKSEL[1:0] bits in SYSCNT_PANEL_CLK of the system controller. When the serial RGB output (3/4 speed mode) is selected in the output controller, the pixel clock frequency is 1/3 or 1/4 the panel clock (LCD_CLK) frequency. Note: Points to be aware of when using LCD_EXTCLK The LCD_EXTCLK signal is multiplexed in three locations: pins PE0, PH5, and PG27. However, it is recommended that pins PE0 and PG27 be used when the digital video decoder is employed. Using pin PH5 can result in the generation of noise on the analog input screen.

Since the Hsync and Vsync signals are used as the reference signals for the LCD TCON, which generates various LCD panel driving timings, they are also the reference signals for the control signals (LCD_TCON6 to LCD_TCON0 pins) passed to the LCD panel. The output Hsync signal always operates at a free-running frequency, and the horizontal period is set with SCL0_FRC4.RES_FH[10:0]. On the other hand, the output Vsync signal is selected from the external input (video decoder or digital pin input) and free-running Vsync signals with SCL0_FRC3.RES_VS_SEL of the scaler. (1) External Input Vsync In this mode, the output Vsync signal is generated according to an external input Vsync signal. For displaying video image input from the video decoder or a digital pin on the panel, always use this mode. However, the output Hsync signal is free running even in this mode.

Noise reduction is controlled through noise component frequency band (TAP), noise level (threshold), and noise reduction intensity (gain). (1) Frequency Band (TAP) Setting for Noise Component The noise frequency band can be selected independently from the following four types by using the NR1D_Y_TAP[1:0], NR1D_CB_TAP[1:0], and NR1D_CR_TAP[1:0] bits. When the number of adjacent pixels is one (noise reduction NR1D_Y/CB/CR_TAP is 0): BPF(1) = ( 1 - 1 x Z ( -1) , 2 x Z (0 ) , - 1 x Z ( +1) 4 ) When the number of adjacent pixels is two (noise reduction NR1D_Y/CB/CR_TAP is 1): BPF( 2) = Page 1916 of 3088 ( 1 - 1 x Z ( -2) , 2 x Z (0 ) , - 1 x Z ( +2) 4 ) R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group Section 32 Video Display Controller 4 (2): Input Controller When the number of adjacent pixels is three (noise reduction NR1D_Y/CB/CR_TAP is 2): BPF(3 ) = ( 1 - 1 x Z ( -3 ) , 2 x Z (0 ) , - 1 x Z ( +3 ) 4 ) When the number of adjacent pixels is four (noise reduction NR1D_Y/CB/CR_TAP is 3): BPF( 4 ) = ( 1 - 1 x Z ( -4 ) , 2 x Z ( 0 ) , - 1 x Z ( +4 ) 4 ) Note: Z(0) indicates the target pixel for noise reduction and Z(N) indicates the pixel that is n pixels off from Z(0) In the horizontal direction. (2) Setting Noise Level (Threshold) The absolute value of the detected noise amount (BPF output value) is compared with the values of the NR1D_Y_TH[6:0], NR1D_CB_TH[6:0], and NR1D_CR_TH[6:0] bits. When the detected noise amount is greater than NR1D_Y/CB/CR_TH, the absolute value of the detected noise amount is considered as NR1D_Y/CB/CR_TH (fixed value). ABS(BPF(n)) absolute value of detected noise amount when ABS(BPF(n)) NR1D_Y/CB/CR_TH: NOISE_ABS = ABS(BPF(n)) ABS(BPF(n)) > absolute value of detected noise amount when ABS(BPF(n)) > NR1D_Y/CB/CR_TH: NOISE_ABS = NR1D_Y/CB/CR_TH (3) Setting Noise Reduction Intensity (Gain) The absolute value of the detected noise amount is multiplied by the value of gain specified by the NR1D_Y_GAIN[1:0], NR1D_CB_GAIN[1:0], and NR1D_CR_GAIN[1:0] bits, and the feedback is calculated for the original signal. Computation when the amount of detected noise (BPF(n)) is negative (-): DOUT = DIN + (NR1D_Y/CB/CR_GAIN+1) NOISE_ABS / 2 Computation when the amount of detected noise (BPF(n) is positive (+): DOUT = DIN - (NR1D_Y/CB/CR_GAIN+1) NOISE_ABS / 2 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 1917 of 3088 SH7268 Group, SH7269 Group Section 32 Video Display Controller 4 (2): Input Controller Table 32.20 Horizontal Noise Reduction Register Name Bit Name Initial Value IMGCNT_NR_CNT0 NR1D_MD 1 Description Horizontal Noise Reduction Operating Mode 0: R/G/B mode 1: Y/Cb/Cr mode IMGCNT_NR_CNT0 NR1D_ON 0 Noise Reduction On/Off Control 0: Noise Reduction Off 1: Noise Reduction On IMGCNT_NR_CNT0 NR1D_Y_TAP[1:0] 0 Y/G Signal TAP Select 0: Adjacent pixel 1: 2 adjacent pixels 2: 3 adjacent pixels 3: 4 adjacent pixels IMGCNT_NR_CNT0 NR1D_Y_TH[6:0] 8 Maximum Value (Absolute Value) of Y/G Signal Coring Coring is implemented when detected noise amount value NR1D_Y_TH.

This is achieved by setting the start timing to receive the next Vsync signal after receiving an input Vsync signal. The Vsync signal reception masking period is set with the RES_VMASK[15:0] bits. Masking period [usec] = RES_VMASK x 128 / pixel clock frequency [MHz] This function is enabled or disabled by the RES_VMASK_ON bit.

This is achieved by setting the wait time after reception of an input Vsync signal until reception of the next Vsync signal. If no Vsync signals are received during the wait time, an internally generated sync signal is inserted. The wait time can be set using the RES_VLACK[15:0] bits. Wait time [usec] = RES_VLACK x 128 / pixel clock frequency [MHz] This function is enabled or disabled by the RES_VLACK_ON bit. If no Vsync signals are input during the Vsync signal reception time, the RES_QVLACK bit is set to the high level. If Vsync signals are continuously detected four or more times during the Vsync signal reception time, the RES_QVLOCK bit is set to the high level. The RES_QVLOCK bit is valid even when both the RES_VMASK_ON and RES_VLACK_ON bits are set to turn off the corresponding functions. Note that, however, the RES_VMASK and RES_VLACK bits must be set correctly. Missing Vsync signal VSIN Wait time VSOUT RES_VLACK[15:0]x128 If no Vsync signal is input during the wait time, a missing-sync compensating pulse is output. After a missing-sync compensation, the wait time measurement is started from the missing-sync pulse.

SCL0_FRC9 RES_QVLOCK Locked Vsync Signal Detection Flag 1: No repeated or missing Vsync signal input has been detected for four or more vertical periods. 0: Repeated or missing Vsync signal input has been detected. For the Vsync signal, repeated-signal masking is first carried out and then missing-signal compensation is carried out, followed by another repeated-signal masking. Repetition masking is inserted after missing-Vsync compensation to prevent output of the Vsync signal even in cases such as the input of a Vsync signal immediately after the input of a pulse to compensate for a missing Vsync signal. On/off control of the missing-Vsync compensation also applies to the second repeated-Vsync masking; and masking period setting of the first repeated-Vsync masking also applies to the second repeated-Vsync masking.

The input format depends on the RES_MD[1:0] bit setting in the writing mode register (SCL1_WR1). When the horizontal reduction ratio is high and there is too much folding frequency component to ignore, the horizontal prefilter should be turned on.

For the scaling filter, either hold or linear interpolation mode can be selected. (1) One-TAP Hold Interpolation When the interpolation position is between input pixels Xn and Xn+1, the Xinterpo interpolation value is defined as follows.

Xinterpo = (Xn x (4096 - phase) + Xn+1 x phase) / 4096 (3) Calculation of Horizontal Scale Down Ratio The value to be set to the horizontal scale-down ratio RES_DS_H_RATIO can be obtained using the following equation based on the number of input pixels RES_HW and number of output pixels RES_OUT_HW, where the decimals are rounded off. RES_DS_H_RATIO = round (RES_HW / RES_OUT_HW x 4096) Note that, for 100% horizontal scale-up, the RES_HW and RES_OUT_HW values should be identical and the RES_DS_H_RATIO bits should be set to 4096. (4) Handling for Lack of Last-Input Pixel Interpolation is carried out between the second-last-input and last-input pixels to produce the lastoutput pixel at the right end of a screen. The interpolation position of the last-output pixel may be close to the second-last-input pixel depending on the horizontal scale-down ratio; in this case, it may appear that the last-input pixel is lacking. The undesirable influence by lack of last-input pixel can be decreased by appropriately adjusting the horizontal scale-down ratio using the following equations. Pre-adjustment horizontal scale-down ratio RATIO_org should be calculated first to find adjustment value , and then scale-down ratio RES_DS_H_RATIO should be determined.

Xinterpo = (Xn x (4096 - phase) + Xn+1 x phase) / 4096 (3) Calculation of Vertical Scale Down Ratio The value to be set to the vertical scale-down ratio RES_V_RATIO can be obtained using the following equation based on the number of input lines RES_VW and number of output lines RES_OUT_VW, where the decimals are rounded off. RES_V_RATIO = round (RES_VW / RES_OUT_VW x 4096) Note that the RES_VW and RES_OUT_VW values should be identical for vertical enlargement or 100% vertical enlargement. For 100% vertical enlargement, reduction is carried out assuming RES_V_RATIO as 4096. (4) Handling for Lack of Last-Input Line Interpolation is carried out between the second-last-input and last-input lines to produce the lastoutput line at the lower end of a screen. The interpolation position of the last-output line may be close to the second-last-input line depending on the vertical scale-down ratio; in this case, it may appear that the last-input line is lacking. The undesirable influence by the lack of last-input line can be decreased by appropriately adjusting the vertical scale-down ratio using the following equations. Pre-adjustment vertical scale-down ratio RATIO_org should be calculated first to find adjustment value , and then scale-down ratio RES_V_RATIO should be determined.

For 128-byte transfer, bits [6:5] in the address control registers should be fixed to 0 since addresses should be specified in 128-byte units. For the data size of a line and the number of lines in a frame, the relevant register values set for the scaling-down control block are used.

Data is written to the buffer in cyclic mode according to the number of frames specified by the RES_FLM_NUM bits. For rotation, the RES_FLM_NUM bits should be set to 1 (2 frames). To use the frame buffer as the ring buffer in line mode, the RES_FLM_NUM bits should be set to 0 (1 frame) and the RES_LOOP bit to 1.

When displaying input video image signals or displaying enlarged graphics, data is read from the frame buffer via the scaling-up control block. However, graphics can be enlarged and displayed by the scaling-up control block only when the RGB565, RGB888, or YCbCr422 format is used. When displaying graphics without enlargement, the data is read from the frame buffer via the graphics 1 processing block. With the RES_IBUS_SYNC_SEL bit, sync signals for reading out the frame buffer and read size setting bits are selected.

Edge enhancement of the blanking signal is turned off. Input signal Output signal after correction Figure 34.6 Sharpness Correction After edge detection of the image, the sharpness can be independently controlled in the three horizontal bands. In horizontal sharpness, a 3-tap low-pass filter (LPF) is inserted before edge detection to prevent folding. The LPF can be turned on or off by register setting.

Edge enhancement is accomplished when the edge detection result of the image is greater than the value of SHP_CORE. In edge enhancement, a correction value is output by multiplying (edge amplitude value SHP_CORE) by sharpness gain. Sharpness is turned off when the edge detection result of the image is smaller than the value of SHP_CORE. When edge amplitude value = SHP_CORE Sharpness turned on using (edge amplitude value-SHP_CORE) When edge amplitude value < SHP_CORE Sharpness turned off SHP_CORE Correction value output Edge detection result Figure 34.7 Sharpness Characteristics R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2075 of 3088 Section 34 Video Display Controller 4 (4): Image Quality Improver SH7268 Group, SH7269 Group Table 34.7 Sharpness Control Register Name Bit Name Initial Value Description ADJ_ENH_SHP1 SHP_H_ON 0 Sharpness On/Off Control 0: Horizontal sharpness off 1: Horizontal sharpness on ADJ_ENH_SHP3 SHP_H2_LPF_ SEL 0 LPF Selection for Folding Prevention Before H2 Edge Detection 0: LPF not selected 1: LPF selected ADJ_ENH_SHP2 SHP_H1_CLIP_O 0 [7:0] Sharpness Correction Value Clipping (on the Overshoot Side) Correction value clipped according to SHP_H1_CLIP_O ADJ_ENH_SHP2 SHP_H1_CLIP_U [7:0] 0 Sharpness Correction Value Clipping (on the Undershoot Side) Correction value clipped according to SHP_H1_CLIP_U ADJ_ENH_SHP2 SHP_H1_GAIN_O 0 [7:0] Sharpness Edge Amplitude Value Gain (on the Overshoot Side) 0 (0 times) to 64 (+1 times) to 255 (+ approx. 4 times) Sharpness correction value = SHP_H1_GAIN_O x (edge amplitude value - SHP_H1_CORE) ADJ_ENH_SHP2 SHP_H1_GAIN_U 0 [7:0] Sharpness Edge Amplitude Value Gain (on the Undershoot Side) 0 (0 times) to 64 (+1 times) to 255 (+ approx. 4 times) Sharpness correction value = SHP_H1_GAIN_U x (edge amplitude value - SHP_H1_CORE) ADJ_ENH_SHP1 SHP_H1_CORE [6:0] 0 Active Sharpness Range Edge amplitude value SHP_H1_CORE: Sharpness processing on Edge amplitude value < SHP_H1_CORE: Sharpness processing off Sharpness processing is always on when the edge detection value is 128 or greater.

Two graphics planes + video or three graphics planes can be selected for synthesis. RGB565, RGB888, RGB1555, RGB4444, RGB8888, CLUT8, CLUT4, CLUT1, and YCbCr422 (for the graphics 1 process) formats can be used for graphics data, and RGB565, RGB888, and YCbCr422 formats for video data. On each of the graphics planes, background color, lower-layer graphics, current graphics, or blended image (graphics 2 and 3 processes) of lower-layer graphics and current graphics can be displayed. The large-capacity on-chip RAM and external SDRAM can be used as the frame buffer. However, display may not be possible if the bus bandwidth is insufficient when using external SDRAM. Therefore, it is recommended that the frame buffer be allocated in the large-capacity on-chip RAM. The functional block diagram of the image synthesizer is shown below.

The register bits of each process can be identified by the number in the register name like GR1_xxxx, GR2_xxxx, and GR3_xxxx, respectively. In the sections except for Register Descriptions, however, the number is omitted like GR_xxxx for convenience sake. (1) Updating Registers The Vsync signal is used to control the update timing of all the registers for graphics display and frame buffer read control. After 1 is set to the bits in the update control register, the contents of the relevant registers are actually modified at the rising edge of the Vsync signal, when the update control register is automatically cleared to 0.

(12) Display Start Pixel Setting for Read Data When a horizontal offset is applied to display the image data in the frame buffer, the display start pixel is set with the GR_BASE[31:0] and GR_STA_POS[5:0] bits. Calculation of the values for the GR_BASE[31:0] and GR_STA_POS[5:0] bits depends on the signal format. The display start pixel can be calculated with the formulas in the table below, where H_OFF is a horizontal offset from the display start pixel.

The system controller controls whether to output these interrupt signals. One is written to the corresponding INT_STA* bit when an interrupt signal is to be accepted. After 1 has been written to the bit, however, its value is still read out as 0 until the interrupt signal is accepted. Once the interrupt signal has been accepted, the INT_STA* bit is read out as 1. The bit for an accepted interrupt signal is cleared by writing 0 to the INT_STA* bit. If further interrupt signals are to be accepted after the INT_STA* bit has been cleared, 1 is again written to the bit.

(1) Specifying 1/7 frequency division In the initial settings after a power-on reset or after returning from deep-standby, and when changing the input source of the panel clock by means of the INP_SEL bit in the INP_SEL_CNT register of the input control block and the PANEL_ICKSEL[1:0] bits, do not fail to perform the steps below to confirm that the 1/7 clock ratio output is selected for the panel clock. (a) After specifying the panel clock input source by means of the INP_SEL bit in the INP_SEL_CNT register of the input control block and the PANEL_ICKSEL[1:0] bits, set the PANEL_DCDR[5:0] bits to specify 1/7 as the clock ratio. (b) Set PANEL_ICKEN to 1. (c) In the scaling block, set the period of the vertical sync signal. (d) Set to 1 the TCON_VEN bit in the TCON_UPDATE register of the output control block. (e) After the vertical sync signal period set in (d) has elapsed, read the TCON_VEN bit. If the read value is 0, the panel clock is being output correctly and the setting procedure is complete. If the read value is 1, the panel clock output is fixed at low or high level. (f) If the output is fixed, initialize video display controller 4 by means of the VDC4SRST bit in the SWRSTCR2 register of the power-down modes, then redo the setting procedure from (a). (2) Specifying 1/3, 1/4, 1/6, 1/8, 1/12, 1/16, 1/24, or 1/32 frequency division In the initial settings after a power-on reset or after returning from deep-standby, and when changing the input source of the panel clock by means of the INP_SEL bit in the INP_SEL_CNT register of the input control block and the PANEL_ICKSEL[1:0] bits, do not fail to perform the steps below to confirm that the 1/12 clock ratio output is selected for the panel clock, then specify the desired clock ratio. If the 1/12 clock ratio output is abnormal, output at the desired clock ratio will also be abnormal. (a) After specifying the panel clock input source by means of the INP_SEL bit in the INP_SEL_CNT register of the input control block and the PANEL_ICKSEL[1:0] bits, set the PANEL_DCDR[5:0] bits to specify 1/12 as the clock ratio. (b) Set PANEL_ICKEN to 1. (c) In the scaling block, set the period of the vertical sync signal. (d) Set to 1 the TCON_VEN bit in the TCON_UPDATE register of the output control block. (e) After the vertical sync signal period set in (d) has elapsed, read the TCON_VEN bit. If the read value is 0, set the PANEL_DCDR[5:0] bits to specify the desired clock ratio and complete the setting procedure.

(f) If the output is fixed, initialize video display controller 4 by means of the VDC4SRST bit in the SWRSTCR2 register of the power-down modes, then redo the setting procedure from (a). (3) Specifying a frequency division ratio other than the above There is no need to confirm the division ratio of the panel clock output. (a) After specifying the panel clock input source by means of the INP_SEL bit in the INP_SEL_CNT register of the input control block and the PANEL_ICKSEL[1:0] bits, set the PANEL_DCDR[5:0] bits to specify the desired clock ratio.

By comparing the CRC code with the pre-calculated expected CRC code value, this module can detect whether the display output is obtained as expected. Main features of this module are as follows. * Graphics data can be selected from graphics plane 1 to graphics plane 3 * Graphics data after blending can be selected * Arbitrary rectangular area of the selected graphics data can be specified * Pixel format can be selected from ARGB88888 and RGB888 for 32 bits/pixel or RGB565 for 16 bits/pixel * Interrupt is generated when the compared CRC codes do not match. 39.4.2 System Configuration This module is configured as shown in figure 39.2. The CRC code is calculated after receiving the graphics data output from the graphics display module. The calculated CRC code is then compared with the pre-calculated expected CRC code value. The graphics data can be selected from graphics plane 1 to graphics plane 3, and the data after blending.

Thus, if the register is updated with the CMPRU bit in DOCMCR as 1, an unexpected result is likely to be obtained in the CRC code calculation. The registers that affect the CRC code calculation (i.e., registers other than DOCMCLSTR and DOCMIENR) should be updated after confirming that the CMPRU bit in DOCMCR is 0. The CMPR bit in DOCMCR is loaded inside upon detection of the start of the valid period of the graphics data. Thus, even if the register is rewritten to in the middle of a frame, the CRC code calculation of the frame does not get affected. (2) Timing when Internal State is Reflected in Registers The internal state is reflected in DOCMSTR and DOCMCCRCR at the end of the valid period of the graphics data. The internal state of the CMPR bit is reflected in the CMPRU bit in DOCMCR at the start of the valid period of the graphics data. Figure 39.5 shows the register update timing.

The interrupt request is generated when the CMPIEN bit in DOCMIENR and the CMPST bit in DOCMSTR are both set to 1. The CMPST bit should be cleared from within the interrupt service routine. However, withdrawing the interrupt request from the CPU after clearing of the CMPST bit takes a fixed amount of time. Thus, avoid erroneous acceptance of the interrupt for which the source bit should have been cleared by checking twice to ensure that the CMPST bit is actually clear, and only then issue the RTE instruction. 39.6 Usage Note 39.6.1 Expected CRC Value When graphics plane 1 to graphics plane 3 are selected, the expected CRC code value (DOCMECRCR) should be calculated from the graphics data to be used by using the software. When the graphics data after blending is selected, the graphics data after blending should be selected at the time of debugging and the calculated CRC code value read from DOCMCCRCR should be used as the expected CRC code value. This is because there is a possibility of mismatching of the result of superimposition of the graphics data by the software and the result of superimposition by the graphics display module due to an error in calculation when the graphics data after blending is selected. 39.6.2 Expansion Control Functionality When scaling settings are applied for expansion processing by video display controller 4, this module becomes incapable of generating CRC codes. Stop this module while expansion processing is being applied.

The JPEG core is activated. A marker is output. (After a marker is output, image data can be input.) Approximately 30,000 cycles (necessary for making SOI to SOS markers) 2. Image data is transferred in MCUs from the external buffer to this module. If the count mode for stopping the input of image data lines is on, reading is stopped each time the number of lines set in JIFESLC is read. Reading is resumed by setting the DINRCMD bit in JIFECNT to 1. When the DINRINI bit in JIFECNT is zero, the addresses for reading on resumption are continued from the addresses in the previous round of transfer. When the DINRINI bit is one, the address set in JIFESA is used on resumption. Reading is also stopped when one frame of image data is completely transferred. If the count mode for stopping the input of image data lines is off, reading is continued until one frame of image data is completely transferred. 3. Image data is input to the JPEG core. The input data is processed in MCUs at any time in the JPEG core. 4. Coded data is transferred from this module to the external buffer. 5. Compression is completed after one frame of data is processed completely.

After this module has been activated, the JPEG markers (SOI to SOS) are generated and output. It takes approximately 30,000 cycles to generate the markers.

However, this module continues processing since the coded data remains to be transferred. The CBTF bit in JINTS1 is set to 1 when the last coded data is transferred. The interrupt source is cleared by writing 0 to the INS6 bit. However, the interrupt request asserted by this interrupt source cannot be cleared by writing 0 to the INS6 bit. Set an interrupt request clear command (by setting the JEND bit in JCCMD to 1) to clear the interrupt request. * When this module has completed compression and all coded data has been transferred, the CBTF flag in JINTS1 is set to 1. When the CBTEN bit in JINTE1 is 1 here, an interrupt is generated. The interrupt source is cleared by writing 0 to the CBTF flag. * If the count mode for stopping image data lines is on, when the specified number of image data lines set in JIFESLC has been read, the DINLF flag in JINTS1 is set to 1, and reading is stopped. When the DINLEN bit in JINTE1 is 1 here, an interrupt is generated. An interrupt source is cleared by writing 0 to the DINLEN bit. Setting the DINRCMD bit in JIFECNT to 1 resumes reading. When the DINRINI bit in JIFECNT is zero, the addresses for reading on resumption are continued from the addresses in the previous round of transfer. When the DINRINI bit is one, the address set in JIFESA is used on resumption. (c) Data Correction When after dividing the output coded data by 8 the remainder is 1 to 6 bytes, transfer of bytes 1 to 6 of the remainder may not complete successfully. If the transfer is unsuccessful, bytes 1 to 6 of the remainder are written to the address specified in the JPEG interface compression destination address register (JIFEDA), overwriting the existing data.* For this reason it is necessary to check whether the output coded data was transferred successfully and, if not, to perform data correction. Note: * This module handles the output of coded data in 16-bit units. For this reason, if the coded data has an odd code length, the final code output will be H'D9FF. (H'FF is appended.) When the remainder is 1, 3, or 5 bytes, the remainder data (1, 3, or 5 bytes) + H'FF is written to the address specified in JIFEDA, overwriting the existing data.

This module handles the output of coded data in 16-bit units. For this reason, if the coded data have an odd code length (are fractional), the final code for output will be H'D9FF. The JOUTSWAP bits in JIFECNT can be used to alter the arrangement of coded data in the output. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2409 of 3088 Section 41 JPEG Codec Unit 41.3.2 (1) SH7268 Group, SH7269 Group Decompression Overview of Processing The decompression process flows are described below. 1. The JPEG core is activated. 2. Coded data is transferred from the external buffer to this module. If the count mode for stopping the input of coded data is on, reading is stopped each time the amount of coded data set in JIFDSLC is read. Reading is resumed by setting the JINRCMD bit in JIFDCNT to 1. When the JINRINI bit in JIFDCNT is zero, the addresses for reading on resumption are continued from the addresses in the previous round of transfer. When the JINRINI bit is one, the address set in JIFDSA is used on resumption. Reading is stopped when the end of the coded data is detected. If the count mode for stopping the input of coded data is off, reading is continued until the end of code is detected. With this module, more coded data may be read than the coded data size since coded data reading is continued until the end of code is detected. 3. Coded data is input to the JPEG core. The input data is processed in MCUs at any time in the JPEG core. 4. Image data is transferred in MCUs from this module to the external buffer. When the count mode for stopping the output of image data lines is on, writing is stopped each time the number of image data lines set in JIFDDLC is written. Writing is resumed by setting the DOUTRCMD bit in JIFECNT to 1. When the DOUTRINI bit in JIFDCNT is zero, the addresses for writing on resumption are continued from the addresses in the previous round of transfer. When the DOUTRINI bit is one, the address set in JIFDDA is used on resumption. Writing is stopped when one frame of image data is completely transferred.

However, this module continues processing since the image data remains to be transferred. The DBTF bit in JINTS1 is set to 1 when the last image data is transferred. The interrupt source is cleared by writing 0 to the INS6 bit. However, the interrupt request asserted by this interrupt source cannot be cleared by writing 0 to the INS6 bit. Set an interrupt request clear command (by setting the JEND bit in JCCMD to 1) to clear the interrupt request. * When this module has completed decompression process and all image data has been transferred, the DBTF flag in JINTS1 is set to 1. When the DBTEN bit in JINTE1 is 1 here, an interrupt is generated. The interrupt source is cleared by writing 0 to the DBTF flag. * If the count mode for stopping input coded data is on, when the specified amount of coded data set in JIFDSDC have been read, the JINF flag in JINTS1 is set to 1, and reading is stopped. When the JINEN bit in JINTE1 is 1 here, an interrupt is generated. An interrupt source is cleared by writing 0 to the JINF bit. Setting the JINRCMD bit in JIFDCNT to 1 resumes reading. When the JINRINI bit in JIFDCNT is zero, the addresses for reading on resumption are continued from the addresses in the previous round of transfer. When the JINRINI bit is one, the address set in JIFDSA is used on resumption. * If the count mode for stopping the output image data is on, when the specified number of image data lines set in JIFDDLC have been written, the DOUTLF flag in JINT1 is set to 1, and writing is stopped. When the DOUTLEN bit in JINTE1 is 1 here, an interrupt is generated. An interrupt source is cleared by writing 0 to the DOUTLF bit. Setting the DOUTRCMD bit in JIFDCNT to 1 resumes writing. When the DOUTRINI bit in JIFDCNT is zero, the addresses for writing on resumption are continued from the addresses in the previous round of transfer. When the DOUTRINI bit is one, the address set in JIFDDA is used on resumption.

Read the ERR bits in JCDERR to determine the cause of the error. The interrupt signal asserted due to the interrupt source indicated by the INS5 bit cannot be negated by clearing the interrupt status through 0-writing. To clear the interrupt request, set the interrupt request clear command (by setting the JEND bit in JCCMD to 1). When performing decompression/compression processing after error handling finishes, start the processing from the initial settings. Start error handling Clear all the flags in JINTS0.

Error handling completed Figure 41.10 Error Handling Flow (2) Input JPEG Coded Data Markers to be processed in decompression are SOI, SOF0, SOS, DQT, DHT, DRI, RSTm, and EOI. Other markers except for the error markers shown below are ignored even if they are read. The JINSWAP bits in JIFDCNT can be used to alter the arrangement for the input of coded data.

When an error is detected, this module generates an interrupt signal and terminates decoding. The stored code value will be set to B'1010 (default value) at the start of processing of the next frame or after a bus reset. Table 41.3 Decompression Error Codes Code Description B'0000 Normal B'0001 SOI not detected: SOI not detected until EOI detected B'0010 SOF1 to SOFF detected B'0011 Unprovided pixel format detected B'0100 SOF accuracy error: Other than 8 detected B'0101 DQT accuracy error: Other than 0 detected B'0110 Component error 1: The number of SOF0 header components detected is other than 1, 3, or 4 B'0111 Component error 2: The number of components differs between SOF0 header and SOS B'1000 SOF0, DQT, and DHT not detected when SOS detected B'1001 SOS not detected: SOS not detected until EOI detected B'1010 EOI not detected (default) B'1011 Restart interval data number error detected B'1100 Image size error detected B'1101 Last MCU data number error detected B'1110 Block data number error detected Page 2416 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (b) Section 41 JPEG Codec Unit Huffman Coded Segment Error During the compressed data analysis in decompression operation, if there is an increase or decrease in the decoded data count due to an error resulting from bit reversal or missing data in the Huffman-coded segment, determine the error type, and set the error code in the ERR bit in JCDERR. Table 41.4 lists the segment error codes. The error code is set, interrupt signal is issued, and the process is ended only if the bits INT7 to INT5 in JINTE0 corresponding to the detected error is set to 1. The set code value will turn to the default value (B'1010) at the start of processing of the next frame or after a bus reset. However, in this error detection, if an error in the Huffman-coded segment does not result in an alteration in the decoded data count, the error will go undetected. [Example] The number of data in a Huffman coded segment with pixel format setting YCbCr422, DRI = 2, X = 80 pixels, and Y = 8 pixels Restart interval 1 SOS Restart interval 2 Coded segment RST Coded segment Restart interval 3 RST Coded segment EOI Number of data in the last MCU: Pixel format setting is YCbCr422, the number of data to be decoded in each MCU is 256. Number of data in the restart interval: In restart intervals 1 and 2, there are data of two MCUs; the number of data to be decoded is 512. Image size: The total number of data to be decoded is 1280. Figure 41.11 Huffman Coded Segment R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2417 of 3088 Section 41 JPEG Codec Unit SH7268 Group, SH7269 Group Table 41.4 Segment Error Codes Code Description B'0000 Normal B'1011 Restart interval data number error: The number of data in each interval is compared with the number of data specified by the DRI marker. If an interval has more or less data that is specified by the DRI marker, the decompression error code (1011) is set. The last interval which is shorter than the restart interval is not compared. If the DRI marker segment is not placed or the specified number is 00, an error is not detected even if the RSTm marker is placed. Also an m which indicates the order of RSTm marker modulo 8 (m = 0 to 7) is exempt from the error detection analysis. When the INT7 bit in JINTE0 is set to 0, this error is not detected. B'1100 Image size error: The data number of an image which is calculated from the number of lines specified by the frame parameter and the number of samples per line is compared with the total number of data from SOS to EOI (in pixel units). If the numbers of data do not match, the decompression error code (1100) is set. When the INT6 bit in JINTE0 is set to 0, this error is not detected. The data number of an image is shown in MCU units. Thus the number of lines and the number of samples per line for calculation need to be shown in MCU units. B'1101 Last MCU data number error: Whether the number of data in the MCUs at the EOI detection is shown in MCU units is checked and fractions are detected. If error (1100) occurs simultaneously, error (1100) has priority. When the INT5 bit in JINTE0 is set to 0, this error is not detected. B'1110 Block data number error: Whether a block is an 8 x 8 array is checked; the check is performed for fractions. When bits INT7 to INT5 in JINTE0 are all set to 0, this error is not detected.

The pixel format of the output image will be YCbCr422, ARGB8888, or RGB565. The flow of conversion of decompressed data to the given output pixel format is shown below.

(2) YCbCr Conversion When data are to be output in the ARGB8888 or RGB565 format, data in the YCbCr422, YCbCr411, or YCbCr420 format are first converted to the YCbCr444 format. When data are to be output in the YCbCr422 format, data in the YCbCr444, YCbCr411, or YCbCr420 format are converted to the YCbCr422 format. Conversion is performed using simple interpolation. (3) YCbCr RGB Conversion Data in the YCbCr444 format are converted to the RGB888 format. The following formulae are used.

For the output format YCbCr422, one cell represents one set of Y0Cb0Y1Cr0 in the figures. As subsampling is carried out by minimum coded units (MCU), the numbers of the horizontal and vertical block units will vary according to the decompressed pixel format.

The two types of interrupt requests are each related to multiple sources. The interrupt request cancellation methods differ depending on the source of the interrupt request. 41.4.1 Compression/Decompression Process Interrupt Request (JEDI) The flags in JINTS0 indicate compression/decompression-related sources. The interrupt requests asserted by these interrupt sources cannot be negated by clearing the corresponding interrupt status bits to 0. Issue an interrupt request clear command (by setting the JEND bit in JCCMD to 1) to clear the interrupt request. When a flag in JINTS0 is set to 1, a compression/decompression process interrupt request is sent to the interrupt controller. (1) Compression * JPEG compression process end When the INS6 bit in JINTS0 is 1, the JPEG compression process has been successfully completed. After all of the coded data is transferred, this module completes compression. (2) Decompression * JPEG decompression process end When the INS6 bit in JINTS0 is 1, the JPEG decompression process has been successfully completed. After all of the image data is transferred, this module completes decompression. * JPEG decompression error occurrence When the INS5 bit in JINTS0 is 1, the input JPEG coded data has an error and this module has stopped the decompression process. Read the error code (ERR bits in JCDERR) and identify the error source. This interrupt occurs when any of the INT7 to INT5 bits in JINTE0 is 1. * Request for reading the image size and pixel format When the INS3 bit in JINTS0 is 1, JPEG coded data has been input and information regarding the image size and pixel format can be read. Since the JPEG decompression process is suspended, resume the JPEG decompression process by setting the process stop clear command after accessing the necessary registers. This interrupt occurs when the INT3 bit in JINTE0 is 1.

The interrupt requests asserted by these interrupt sources can be negated by clearing the corresponding interrupt status bits to 0. (1) Compression * Interrupt request generated after the specified number of input image data lines has been read When the DINLF bit in JINTS1 is 1, the number of image data lines specified by JIFESLC has been transferred; transfer the rest of the image data to the external buffer and resume transferring the data from the external buffer. A data transfer interrupt request is sent when the DINLEN bit in JINTE1 is 1. * Interrupt request generated after all processes are completed When the CBTF bit in JINTS1 is 1, this module has completed compression and transferred all of the coded data. The data transfer interrupt request is sent when the CBTEN bit in JINTE1 is set to 1.

A data transfer interrupt request is sent when the DOUTLEN bit in JINTE1 is 1. * Interrupt request generated after the specified amount of input coded data has been read The JINF bit in JINTS1 becomes 1 when the amount of coded data specified by JIFDSDC has been transferred. Secure the next coded data in the external buffer, and resume transfer process. A data transfer interrupt is also sent at this time if the JINEN bit in JINTE1 is 1. * Interrupt request generated after all processes are completed The DBTF bit in JINTS1 becomes 1 when this module has completed decompression and transferred all of the coded data.

On the other hand, video display controller 4 treats the range from 0 to 255 as input/output values for YCbCr. Therefore, when bidirectionally transferring data in YCbCr pixel formats between this module and video display controller 4, correct YCbCr values by adding or subtracting 128.

All the bits are read as 0. The data input to SRCID is stored in the 8-stage input data FIFO. When the number of data units in the input data FIFO is 8, writing to SRCID has no effect. For stereo data, bits 31 to 16 are for Lch data, and bits 15 to 0 are for Rch data. For monaural data, data in bits 31 to 16 is valid, and data in bits 15 to 0 is invalid.

In addition, when 1 is written to the FL bit while the number of data units in the input buffer memory is less than the values shown in table 42.6, valid output data cannot be received. Thus the internal work memory is cleared without triggering the flush processing.

Table 42.7 summarizes the interrupts. Table 42.7 Interrupt Requests and Generation Conditions Direct Memory Access Controller Activation Interrupt Request Abbreviation Interrupt Condition Input data FIFO empty IDEI IINT = 1, IEN = 1, and SRCEN = 1 Possible Output data FIFO full ODFI OINT = 1, OEN = 1, and SRCEN = 1 Possible Output data FIFO overwrite OVF OVF = 1, OVEN = 1, and Not possible SRCEN = 1 Output data FIFO underflow UDF UDF = 1, UDEN = 1, and Not possible SRCEN = 1 Conversion end CEF CEF = 1, CEEN = 1, and Not possible SRCEN = 1 When the interrupt condition is satisfied, the CPU executes the interrupt exception handling routine. The interrupt source flags should be cleared in the routine. The IDEI and ODFI interrupts can activate the direct memory access controller when the direct memory access controller is set to allow this. If the direct memory access controller is activated, the interrupts from this module are not sent to the CPU. When the direct memory access controller has written data to SRCID resulting in the number of data units in the input data FIFO exceeding that of the specified triggering number, the IINT bit is cleared to 0. Similarly, when the direct memory access controller has read data from SRCOD resulting in the number of data units in the output data FIFO being less than the specified triggering number, the OINT bit is cleared to 0.

To check the updated SRCSTAT state, dummy-read SRCCTRL or SRCSTAT after the instruction used to write to SRCCTRL. 42.5.2 Notes on Flush Processing When 1 is written to the FL bit in SRCCTRL, this module continues conversion processing by adding 0-data to the input data end point. Flush processing, therefore, should be performed when the audio data end point is input and there is no subsequent data. To perform conversion again after flush processing, clear the internal work memory in either of the following ways. * Write 1 to the CL bit in SRCCTRL. * Write 0 and then 1 to the SRCEN bit in SRCCTRL.

The operation stop procedure, operating clock and attenuator function on/off settings are specified by the SGCR1 setting. When the attenuator function is on, the attenuation cycle is selected. The interrupt request is set by the SGIE bit in SGCSR. (2) Activation The operation of this module is enabled by setting the SGST bit in SGCR1 to 1 and clearing the SGEND bit in SGCR2 to 0. Set the TCHG bit in SGCR2 to 1 to cancel the write protect for SGSFR and SGTFR. Use bits SFS7 to SFS0 in SGSFR to select the reference frequency and bits TONE6 to TONE0 in SGTFR to select the tone frequency. SGLR specifies the output pulse duty. This module starts operation after writing to SGCR2, SGLR, SGTFR, and SGSFR is completed. (3) Stopping The operation stop procedure of this module is specified by the STPM bit in SGCR1. When the attenuator function is off and STPM is 0, the operation is stopped by the SGST bit regardless of the SGEND bit setting. When the attenuator function is off and STPM is 1, the operation is stopped by clearing the SGST bit to 0 and setting the SGEND bit to 1. When the attenuator function is on and STPM is 0, clearing the SGST bit to 0 stops operation even though the automatic attenuation does not end and the SGDEF bit is not set to 1. When the attenuator function is on and STPM is 1, clearing the SGST bit to 0 does not stop operation until the automatic attenuation ends and the SGDEF bit is set to 1.

The tone frequency is calculated by: Reference frequency (Hz) = SGCLK (Hz)/SFS Tone frequency (Hz) = Reference frequency (Hz)/(2 x TONE) = SGCLK (Hz)/(2 x SFS x TONE) Setting values of the TONE bit in SGTFR and SFS bit in SGFSR are calculated by: SFS = SGCLK (Hz)/reference frequency (Hz) (0 < SFS 255) TONE = Reference frequency (Hz)/(2 x TONE frequency (Hz)) (0 < TONE 127) An example of relationship between the tone frequency and output error is shown in table 43.4.

This module generates three types of interrupt requests: normal operation, error/timeout, and card detection. When an interrupt flag is set to 1and also the corresponding interrupt is enabled, an interrupt request is asserted.

The DMA transfer request stays asserted for the amount of data specified by BLKSIZ (the block size set in CE_BLOCK_SET) x BLKCNT (the number of blocks for transfer set in CE_BLOCK_SET), and negated after the last block has been transferred. Note that the BUFWEN bit in CE_INT will not be asserted during DMA transfer. If an error has occurred during DMA transfer or DMA transfer is forcibly terminated, the command sequence is stopped automatically, which causes the DMA transfer request to be negated. 45.5.2 DMA for Buffer Reading The DMA transfer request is asserted for buffer reading when the buffer stores data of the block size specified in CE_BLOCK_SET while the DMAREN bit in CE_BUF_ACC is set to 1. The DMA transfer request stays asserted for the amount of data specified by BLKSIZ (the block size set in CE_BLOCK_SET) x BLKCNT (the number of blocks for transfer set in CE_BLOCK_SET), and negated after the last block has been transferred. Note that the BUFREN bit in CE_INT will not be asserted during DMA transfer. If an error has occurred during DMA transfer or DMA transfer is forcibly terminated, the command sequence is stopped automatically, which causes the DMA transfer request to be negated.

Therefore, for multi-block writing, if one block of data (512 bytes) stored in one buffer has been transmitted but the other buffer is full, the next block of data can be continuously transmitted. For multi-block reading, if one block of receive data has been stored in one buffer but the other buffer is empty, the next block of receive data can be continuously stored in the buffer. If neither of the buffers is empty for multi-block reading, the MMC clock is stopped and reception is suspended. When one of the buffers becomes empty, the MMC clock supply is started to start reception. The buffer is accessed with CE_DATA. If the transfer block size is set to 4 x n + 1 or 4 x n + 3, CE_DATA should be accessed for 4 x n + 2 bytes or 4 x (n + 1) bytes in 16-bit access, and for 4 x (n + 1) bytes in 32-bit access.

(1) Initial Settings Set the PWM output polarity in PWPR_n; select the clock to be input to PWCNT_n with the CKS2 to CKS0 bits in PWCRn; set the PWM conversion cycle in PWCYR_n; and set the first frame of data in PWBFR_nA, PWBFR_nC, PWBFR_nE, and PWBFR_nG. (2) Activation When the CST bit in PWCR_n is set to 1, PWCNT_n starts counting up. On compare match between PWCNT_n and PWCYR_n, data is transferred from the buffer register to the duty register and the CMF bit in PWCR_n is set to 1. At the same time, if the IE bit in PWCR_n has been set to 1, an interrupt can be requested or the direct memory access controller can be activated. (3) Waveform Output The PWM outputs selected by the OTS bits in PWDTR_nA, PWDTR_nC, PWDTR_nE, and PWDTR_nG go high when a compare match occurs between PWCNT_n and PWCYR_n. The PWM outputs not selected by the OTS bit are low. When a compare match occurs between PWCNT_n and PWDTR_nA, PWDTR_nC, PWDTR_nE, or PWDTR_nG, the corresponding PWM output goes low. If the corresponding bit in PWPR_n is set to 1, the output is inverted.

PWCNT_n is reset and starts counting up from H'000. The CMF bit in PWCR_n is set, and if the IE bit in PWCR_n has been set, an interrupt can be requested or the direct memory access controller can be activated. (5) Stopping When the CST bit in PWCR_n is cleared to 0, PWCNT_n is reset and stops. All PWM outputs go low (or high if the corresponding bit in PWPR_n is set to 1). 46.5.2 Buffer Transfer Control Setting a corresponding bit in the PWM buffer transfer control register disables a buffer transfer on compare match. This prevents the output from changing when compare match occurs while the buffer register is being changed. A buffer transfer on compare match is resumed after cleaning the bit.

PWM output changed by the cycle register compare match is not changed by modification of the duty register due to conflict. This may result in unanticipated duty output. Buffer register modification must be completed before automatic transfer by the direct memory access controller, exception handling due to a compare match interrupt, or the occurrence of a cycle register compare match on detection of the rise of CMF (compare match flag) in PWCR_n.

(Note that the F bus is connected only to the read ports.) The F bus and M bus are used for access by the CPU, and the ID bus is used for access by the direct memory access controller. Each page of the on-chip large-capacity RAM has one read and write port and is connected to the internal CPU bus (IC bus), internal DMA bus (ID bus) and internal graphics buses (IV1 to IV4, RGP1 to RGP4).

Although each access is completed correctly, this kind of conflict degrades the memory access speed. Therefore, it is advisable to provide software measures to prevent such conflicts as far as possible. For example, no conflict will arise if different pages are accessed by each bus. 47.2.2 RAME and RAMWE Bits Before disabling memory operation or write access to the on-chip high-speed RAM through the RAME or RAMWE bit, be sure to read from any address and then write to the same address in each page; otherwise, the last written data in each page may not be actually written to the RAM. // For page 0 MOV.L #H'FFF80000,R0 MOV.L @R0,R1 MOV.L R1,@R0 // For page 1 MOV.L #H'FFF84000,R0 MOV.L @R0,R1 MOV.L R1,@R0 // For page 2 MOV.L #H'FFF88000,R0 MOV.L @R0,R1 MOV.L R1,@R0 // For page 3 MOV.L #H'FFF8C000,R0 MOV.L @R0,R1 MOV.L R1,@R0 Figure 47.1 Examples of Read/Write Page 2558 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group 47.2.3 Section 47 On-Chip RAM Data Retention Data in the on-chip high-speed RAM and the large-capacity RAM (including on-chip data retention RAM) are retained in the states other than power-on reset and deep standby mode. In power-on reset and deep standby mode, these RAMs operate as described below.

Data are not retained when the setting of the VRAME and VRAMWE bits are both enabled. (c) On-Chip Data Retention RAM Data are retained on a power-on reset by disabling the setting of any of the VRAME, VRAMWE, or RRAMWE, excluding the case that deep standby mode is canceled by power-on reset. Data are not retained when the setting of the VRAME, VRAMWE and RRAMWE bits are all enabled. (2) Deep Standby Mode (a) On-Chip High-Speed RAM and On-Chip Large-Capacity RAM (Excluding On-Chip Data Retention RAM) Data are not retained. (b) On-Chip Data Retention RAM Data are retained in deep standby mode by enabling the setting of the RRAMKP bit, excluding the case that deep standby mode is canceled by power-on reset. In the case that deep standby mode is canceled by interrupt or pins for cancelling, power-on reset exception handling is executed, but the data are retained.

The PA1IOR and PA0IOR bits correspond to the PA1 and PA0 pins, respectively. If a bit in PAIOR0 is set to 1, the corresponding pin on port A functions as output. If it is cleared to 0, the corresponding pin function as input. Bits 15 to 9, and 7 to 1 in PAIOR0 are reserved. These bits are always read as 0. The write value should always be 0.

The PA1DR and PA0DR bits correspond to the PA1 and PA0 pins, respectively. When a pin function is general output, if a value is written to PADR0, that value is output from the pin, and if PADR0 is read, the register value is returned regardless of the pin state. When a pin function is general input, if PADR0 is read, the pin state, not the register value, is returned directly. If a value is written to PADR0, although that value is written into PADR0, it does not affect the pin state. Table 48.12 summarizes PADR0 read/write operation.

The PB22IOR to PB1IOR bits correspond to the PB22 to PB1 pins, respectively. PBIOR1 and PBIOR0 are enabled when the port B pins are functioning as generalpurpose I/O (PB22 to PB1) or TIOC I/O of multi-function timer pulse unit 2. In other states, they are disabled. If a bit in PBIOR1 or PBIOR0 is set to 1, the corresponding pin on port B functions as output pin. If it is cleared to 0, the corresponding pin functions as an input pin. Bits 15 to 7 in PBIOR1 and bit 0 in PBIOR0 are reserved. These bits are always read as 0. The write value should always be 0.

The PB22DR to PB1DR bits correspond to the PB22 to PB1 pins, respectively. When a pin function is general output, if a value is written to PBDR1 or PBDR0, the value is output directly from the pin, and if PBDR is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PBDR1 or PBDR0 is read, the pin state, not the register value, is returned directly. If a value is written to PBDR1 or PBDR0, although that value is written into PBDR1 or PBDR0, it does not affect the pin state. Table 48.13 summarizes PBDR1/PBDR0 read/write operation.

The setting of PDIOR0 is valid for the pins for which general I/O function is selected and has no effect on the pins for which other function is selected. If a bit in PDIOR0 is set to 1, the corresponding pin on port D functions as an output. If it is cleared to 0, the corresponding pin functions as an input.

The PD15DR to PD0DR bits correspond to the PD15 to PD0 pins, respectively. When a pin function is general output, if a value is written to PDDR0, that value is output directly from the pin, and if PDDR0 is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PDDR0 is read, the pin state, not the register value, is returned directly. If a value is written to PDDR0, although that value is written into PDDR0, it does not affect the pin state. Table 48.15 summarizes PDDR0 read/write operation.

The PE7IOR to PE0IOR bits correspond to the PE7 to PE0 pins respectively. PEIOR0 is enabled when the port E pins are functioning as general-purpose inputs/outputs (PE7 to PE0). In other states, it is disabled. If a bit in PEIOR0 is set to 1, the corresponding pin on port E functions as an output pin. If it is cleared to 0, the corresponding pin functions as an input pin. Bits 15 to 8 of PEIOR0 and bits 7 to 4 of PEIOR0 in the SH7268 Group are reserved. This bit is always read as 0. The write value should always be 0.

The PE7DR to PE0DR bits correspond to the PE7 to PE0 pins, respectively. 8 pins on Port E are open-drain outputs. When a pin function is general output, if 0 is written to PEDR0, 0 is output from the pin and if 1 is written to, the pin will be in the high-impedance state. If PEDR0 is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PEDR0 is read, the pin state, not the register value, is returned directly. If a value is written to PEDR0, although that value is written into PEDR0, it does not affect the pin state. Table 48.16 summarizes PEDR0 read/write operation.

The PF23IOR to PF0IOR bits correspond to the PF23 to PF0 pins, respectively. PFIOR0 or PFIOR1 is enabled when the port F pins are functioning as generalpurpose I/O (PF23 to PF0) or TIOC I/O of multi-function timer pulse unit 2. In other states, they are disabled. If a bit in PFIOR0 or PFIOR1 is set to 1, the corresponding pin on port F functions as an output. If it is cleared to 0, the corresponding pin functions as an input. Bits 15 to 8 in PFIOR1 are reserved. These bits are always read as 0. The write value should always be 0.

The PF23DR to PF0DR bits correspond to the PF23 to PF pins respectively. When a pin function is general output, if a value is written to PFDR0 or PFDR1, that value is output directly from the pin, and if PFDR0 or PFDR1 is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PFDR0 or PFDR1 is read, the pin state, not the register value, is returned directly. If a value is written to PFDR0 or PFDR1, although that value is written into PFDR0 or PFDR1, it does not affect the pin state. Table 48.17 summarizes PFDR0/PDFR1 read/write operation.

The PG27IOR to PG0IOR bits correspond to the PG27 to PG0, respectively. PGIOR1 and PGIOR0 are enabled when the port G pins are functioning as general-purpose I/O (PG27 to PG0) or TIOC I/O of multi-function timer pulse unit 2. In other states, they are disabled. If bits in PGIOR1 and PGIOR0 are set to 1, corresponding pins on port G functions as outputs. If they are cleared to 0, the corresponding pins function as inputs. Bits 15 to 12 in PGIOR1 are reserved. These bits are always read as 0. The write values should always be 0.

The PG27DR to PG0DR bits correspond to the PG27 to PGDR0 pins, respectively. When a pin function is general output, if a value is written to PGDR1 or PGDR0, that value is output from the pin, and if PGDR1 or PGDR0 is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PGDR1 or PGDR0 is read, the pin state, not the register value, is returned directly. If a value is written to PGDR1 or PGDR0, although that value is written into PGDR1 or PGDR0, it does not affect the pin state. Table 48.18 summarizes PGDR1/PGDR0 read/write operation.

The PJ31IOR to PJ0IOR bits correspond to the PJ31 to PJ0 pins respectively. The setting of PJIOR0 or PJIOR1 is valid for the pins for which general I/O (PJ31 to PJ0) function and has no effect on the pins for which other function is selected. If a bit in PJIOR0 or PJIOR1 is set to 1, the corresponding pin on port J functions as an output pin. If it is cleared to 0, the corresponding pin functions as an input pin.

The PJ31DR to PJ0DR bits correspond to the PJ31 to PJ0 pins, respectively. When a pin function is general output, if a value is written to PJDR0 or PJDR1, that value is output from the pin, and if PJDR0 or PJDR1 is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PJDR0 or PJDR1 is read, the pin state, not the register value, is returned directly. If a value is written to PJDR0 or PJDR1, although that value is written into PJDR0 or PJDR1, it does not affect the pin state. Table 48.19 summarizes PJDR0/PJDR1 read/write operation.

In power-down modes, functions of CPU, clocks, on-chip memory, or part of on-chip peripheral modules are halted or the power-supply is turned off, through which low power consumption is achieved. These modes are canceled by a reset or interrupt. 49.1 Features 49.1.1 Power-Down Modes This LSI has the following power-down modes and function: 1. Sleep mode 2. Software standby mode 3. Deep standby mode 4. Module standby function Table 49.1 shows the transition conditions for entering the modes from the program execution state, as well as the CPU and peripheral module states in each mode and the procedures for canceling each mode.

The pin state is retained or set to high impedance. For details, see section 53.1, Pin States in section 53, States and Handling of Pins. 2. The realtime clock operates when the START bit in the RCR2 register is set to 1. For details, see section 15, Realtime Clock. When deep standby mode is canceled by a power-on reset, the running state cannot be retained. Make the initial setting for the realtime clock again. 3. Setting the bits RRAMKP3 to RRAMKP0 in the RRAMKP register to 1 enables to retain the data in the corresponding area on the on-chip data-retention RAM during the transition to deep standby. When the deep standby is canceled by a power-on reset, the retained contents are initialized. 4. Deep standby mode can be canceled by an interrupt (NMI or realtime clock alarm interrupt), a power-on reset, or change on the pins for canceling (PJ23 to PJ20, PG3, PG2, PF19 to PF16, PC7, and PC5). Even when deep standby mode is canceled by a source other than a reset, power-on reset exception handling is executed instead of interrupt exception handling. PJ23 to PJ20 can be used only in the SH7269 Group. 5. When software standby mode is canceled by a power-on reset, the retained contents are initialized. 6. By setting the RAME bit in SYSCR1 or RAMWE bit in SYSCR2 to disable accesses, contents in the high-speed on-chip RAM can be retained even when software standby mode is canceled by a power-on reset. 7. By setting the VRAME bit in SYSCR3 or VRAMWE bit in SYSCR4 to disable accesses, contents in the large-capacity on-chip RAM (including on-chip data-retention RAM) can be retained even when software standby mode is canceled by a power-on reset.

Although the CPU halts immediately after executing the SLEEP instruction, the contents of its internal registers remain unchanged. The on-chip peripheral modules continue to run in sleep mode. The clock output from the CKIO pin is continued. (2) Canceling Sleep Mode Sleep mode is canceled by an interrupt (NMI, IRQ, and on-chip peripheral module), a DMA address error, or a reset (manual reset or power-on reset). * Canceling by an interrupt When an NMI, IRQ, or on-chip peripheral module interrupt occurs, sleep mode is canceled and interrupt exception handling is executed. When the priority level of the generated interrupt is equal to or lower than the interrupt mask level that is set in the status register (SR) of the CPU, or the interrupt by the on-chip peripheral module is disabled on the module side, the interrupt request is not accepted and sleep mode is not canceled. * Canceling by a DMA address error When a DMA address error occurs, sleep mode is canceled and DMA address error exception handling is executed. * Canceling by a reset Sleep mode is canceled by a power-on reset or a manual reset.

In software standby mode, not only the CPU but also the clock and on-chip peripheral modules halt. The clock output from the CKIO pin also stops. The contents of the CPU and cache registers remain unchanged. Some registers of on-chip peripheral modules are, however, initialized. As for the states of on-chip peripheral module registers in software standby mode, see section 51.3, Register States in Each Operating Mode. The CPU takes one cycle to finish writing to STBCR1, and then executes processing for the next instruction. However, it takes one or more cycles to actually write. Therefore, execute a SLEEP instruction after reading STBCR1 to have the values written to STBCR1 by the CPU to be definitely reflected in the SLEEP instruction. The procedure for switching to software standby mode is as follows: 1. Clear the TME bit in the timer control register of the watchdog timer (WTCSR) to 0 to stop the watchdog timer. 2. Set the timer counter (WTCNT) of the watchdog timer to 0 and the CKS[2:0] bits in WTCSR to appropriate values to secure the specified oscillation settling time. 3. After setting the STBY and DEEP bits in STBCR1 to 1 and 0 respectively, read STBCR1. Then, execute a SLEEP instruction. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2717 of 3088 Section 49 Power-Down Modes (2) SH7268 Group, SH7269 Group Canceling Software Standby Mode Software standby mode is canceled by interrupts (NMI or IRQ) or a reset (power-on reset). Clock signal starts to be output from the CKIO pin. * Canceling by an interrupt When the falling edge or rising edge of the NMI pin (selected by the NMI edge select bit (NMIE) in the interrupt control register 0 (ICR0) of the interrupt controller) or the falling edge or rising edge of an IRQ pin (IRQ7 to IRQ0) (selected by the IRQn sense select bits (IRQn1S and IRQn0S) in interrupt control register 1 (ICR1) of the interrupt controller) is detected, clock oscillation is started. This clock pulse is supplied only to the oscillation settling counter (watchdog timer) used to count the oscillation settling time. After the elapse of the time set in the clock select bits (CKS[2:0]) in the watchdog timer control/status register (WTCSR) of the watchdog timer before the transition to software standby mode, the watchdog timer overflow occurs. Since this overflow indicates that the clock has been stabilized, the clock pulse will be supplied to the entire chip after this overflow. Software standby mode is thus cleared and NMI interrupt exception handling (IRQ interrupt exception handling in case of IRQ) is started. If the priority level of the generated interrupt is equal to or lower than the interrupt mask level specified in the status register (SR) of the CPU, the interrupt request is not accepted and software standby mode is not canceled. When canceling software standby mode by the NMI interrupt or IRQ interrupt, set the CKS[2:0] bits so that the watchdog timer overflow period will be equal to or longer than the oscillation settling time. The clock output phase of the CKIO pin may be unstable immediately after detecting an interrupt and until software standby mode is canceled. * Canceling by a reset When the RES pin is driven low, software standby mode is canceled and the LSI enters the power-on reset state. After that, if the RES pin is driven high, the power-on reset exception handling is started. Keep the RES pin low until the clock oscillation settles. The internal clock will continue to be output to the CKIO pin.

If, however, a SLEEP instruction and an interrupt other than NMI and IRQ are generated at the same time, software standby mode may be canceled due to acceptance of the interrupt. When initiating a transition to software standby mode, make settings so that interrupts are not generated before execution of the SLEEP instruction. (4) Note on Canceling Software Standby Mode After software standby mode is canceled, unstable clock pulses are output from the CKIO pin during oscillation settling time. To prevent malfunction due to the unstable pulses, bits 13 and 12 in FRQCR should be modified. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2719 of 3088 SH7268 Group, SH7269 Group Section 49 Power-Down Modes 49.3.3 Software Standby Mode Application Example This example describes a transition to software standby mode on the falling edge of the NMI signal, and cancellation on the rising edge of the NMI signal. The timing is shown in figure 49.1. When the NMI pin is changed from high to low level while the NMI edge select bit (NMIE) in the interrupt control register 0 (ICR0) is set to 0 (falling edge detection), the NMI interrupt is accepted. When the NMIE bit is set to 1 (rising edge detection) by the NMI exception service routine, the STBY and DEEP bits in STBCR1 are set to 1 and 0 respectively, and a SLEEP instruction is executed, software standby mode is entered. Thereafter, software standby mode is canceled when the NMI pin is changed from low to high level.

In deep standby mode, not only the CPU, clocks, and on-chip peripheral modules but also power supply is turned off excluding the on-chip data-retention RAM area specified by the RRAMKP3 to RRAMKP0 bits in RRAMKP and realtime clock. This can significantly reduce power consumption. Therefore, data in the registers of the CPU, cache, and on-chip peripheral modules are not retained. Pin state values immediately before the transition to deep standby mode are retained. The CPU takes one cycle to finish writing to DSFR, and then executes processing for the next instruction. However, it actually takes one or more cycles to write. Therefore, execute a SLEEP instruction after reading DSFR to reflect the values written to DSFR by the CPU in the SLEEP instruction without fail. The procedure for switching to deep standby mode is as follows. Figure 49.2 also shows its flowchart. 1. Set the RRAMKP3 to RRAMKP0 bits in RRAMKP for the corresponding on-chip dataretention RAM area that must be retained. Transfer the programs to be retained to the specified areas of the on-chip data-retention RAM. 2. Set the RAMBOOT and EBUSKEEPE bits in DSCTR to specify the activation method for returning from deep standby mode and to select whether the external memory control pin status is retained or not. 3. When canceling deep standby mode by an interrupt, set the corresponding bit in DSSSR to select the pin or source to cancel deep standby mode. In this case, specify the input signal detection mode for the selected pin with the corresponding bit in DSESR. 4. Execute read and write of an arbitrary but the same address for each page in the on-chip dataretention RAM area. When this is not executed, data last written may not be written to the onchip data-retention RAM. If there is a write to the on-chip data-retention RAM after this time, execute this processing after the last write to the on-chip data-retention RAM. 5. Set the STBY and DEEP bits in STBCR1 to 1. 6. Read out the DSFR register after clearing the flag in the DSFR register. Then execute the SLEEP instruction.

The realtime clock alarm interrupt can always cancel deep standby mode regardless of the interrupt priority level or the status register (SR) setting in the CPU. When canceling the mode by a source other than a reset, a power-on reset exception handling is executed instead of an interrupt exception handling. Figure 49.3 shows the flowchart of canceling deep standby mode. Deep standby mode Detect an interrupt (NMI or realtime clock alarm). Detect change on the pins for canceling.

After the oscillation settling time has elapsed, deep standby mode is cancelled and the power-on reset exception handling is executed. The clock output phase of the CKIO pin may be unstable immediately after detecting a cancel source and until deep standby mode is canceled. The detecting of the NMI pin, the pins for canceling, and the realtime clock alarm interrupt becomes enable when the corresponding bits in DSSSR are set. The detected cancel sources are kept, but they are reflected to DSFR after canceling the deep standby mode. When the CPU accepts any interrupts, all of the cancel sources that are kept are cleared. When the CPU enters the deep standby mode as the detected cancel sources are kept, the deep standby mode is canceled immediately after the CPU enters the deep standby mode. * Canceling with a reset Driving the RES pin low cancels deep standby mode and causes a transition to the power-on reset state. After this, driving the RES pin high initiates power-on reset exception handling. Output of the internal clock from the CKIO pin also starts by driving the RES pin low. Keep the RES pin low until the clock oscillation has settled.

By setting the EBUSKEEPE bit, the states of the external memory control pins can be retained even after cancellation of deep standby mode. Table 49.3 shows the pin states after cancellation of deep standby mode according to the setting of each bit. Table 49.4 lists the external memory control pins.

Pins retain the state immediately before the transition to deep standby mode. However, in system activation through the external memory, the retention of the states of the external memory control pins is cancelled so that programs can be fetched after cancellation of deep standby mode. Other pins, after cancellation of deep standby mode, continue to retain the pin states until writing 0 to the IOKEEP bit in DSFR after reading 1 from the same bit. In system activation from the on-chip data-retention RAM, after cancellation of deep standby mode, both the external memory control pins and other pins continues to retain the pin states until writing 0 to the IOKEEP bit in DSFR after reading 1 from the same bit. Reconfiguration of peripheral functions is required to return to the previous state of deep standby mode. Peripheral functions include all functions such as the clock pulse generator, interrupt controller, general I/O ports, and peripheral modules. After the reconfiguration, the retention of the pin state can be canceled and the LSI returns to the state prior to the transition to deep standby mode by reading 1 from the IOKEEP bit in DSFR and then writing 0 to it. (4) Notes on Transition to Deep Standby Mode If multiple canceling sources have been specified and multiple canceling sources are input, multiple cancel source flags will be set.

This function can be used to reduce the power consumption in the program execution state and sleep mode. Disable a module before placing it in the module standby mode. In addition, do not access the module's registers while it is in the module standby state. For details on the states of registers, see section 51.3, Register States in Each Operating Mode. (2) Canceling Module Standby Function The module standby function can be canceled by clearing each MSTP bit to 0, or by a power-on reset (only possible for the realtime clock, user debugging interface, and direct memory access controller). When taking a module out of the module standby state by clearing the corresponding MSTP bit to 0, read the MSTP bit to confirm that it has been cleared to 0. 49.3.6 Adjustment of XTAL Crystal Oscillator Gain The gain of the crystal oscillator can be adjusted using the GAIN bit in XTALCTR. To modify the gain, PLL settling time is needed. The settling time is counted using the on-chip watchdog timer. 1. The large gain is selected in the initial state. 2. Set the watchdog timer so that the specified settling time should be obtained and stop the watchdog timer. Specifically, the following settings are necessary: TME in WTCSR = 0: Stop the watchdog timer. CKS[2:0] in WTCSR: Division ratio for watchdog timer count clock WTCNT: Initial counter value (The watchdog timer starts counting on the set clock.) 3. Set the GAIN bit to the desired value. 4. The LSI is internally stopped and the watchdog timer starts counting. The clock is supplied only to the watchdog timer and other internal clocks are stopped. In this state, the CKIO pin continues to output an unstable clock. To avoid malfunction due to the unstable clock, modify the CKOEN2 bit in FRQCR appropriately. Since this state is equivalent to the software standby mode state, some registers of on-chip peripheral modules are initialized. For details, see section 51.3, Register States in Each Operating Mode. 5. When an overflow occurs on the watchdog timer, the specified clock supply is started and the LSI starts operation. The watchdog timer stops after an overflow.

When writing to the register related to power-down modes, the CPU, after executing a write instruction, executes the next instruction without waiting for the write operation to complete. Therefore, to reflect the change specified by writing to the register while the next instruction is executed, insert a dummy read of the same register between the register write instruction and the next instruction. 49.4.2 Usage Notes when the Realtime Clock is not Used When the realtime clock is not used, set the MSTP30 bit in STBCR3 to 1 after setting the bits in registers of the realtime clock. For details, see section 49.2.3, Standby Control Register 3 (STBCR3).

This module incorporates a boundary scan TAP controller and an emulation TAP controller for controlling the user debugging interface interrupt function. When the TRST pin is asserted, including the case of power-on, the boundary scan TAP controller is selected. By inputting the emulation TAP controller switching command, the emulation TAP controller is selected. To switch from the emulation TAP controller to the boundary scan TAP controller, assert the TRST pin. In ASE mode, the emulation TAP controller is selected. For connection with the emulator, see the manual for the emulator. Figure 50.1 shows a block diagram.

Mode select input pin TMS Input The state of the TAP control circuit is determined by changing this signal in synchronization with TCK. The protocol complies with the JTAG standard (IEEE Std.1149.1). Reset input pin TRST Input Input is accepted asynchronously with respect to TCK, and when low, this module is reset. TRST must be low for a period when power is turned on regardless of using the function. See section 50.5.2, Reset Configuration, for more information. Serial data input pin TDI Input Data is transferred to this module by changing this signal in synchronization with TCK. Serial data output pin TDO Output Data is read from this module by reading this pin in synchronization with TCK. The initial value of the data output timing is the TCK falling edge, but this initial value can be changed to the TCK rising edge by inputting the TDO transition timing switching command to SDIR. See section 50.5.3, TDO Output Timing, for more information. ASE mode select pin ASEMD* Input Note: * If a low level is input at the ASEMD pin while the RES pin is asserted, ASE mode is entered; if a high level is input, product chip mode is entered. In ASE mode, dedicated emulator function can be used. The input level at the ASEMD pin should be held for at least one cycle after RES negation. When the emulator is not in use, fix this pin to the high level.

The TDI value is sampled at the rising edge of TCK; shifting occurs at the falling edge of TCK. For details on transition timing of the TDO value, see section 50.5.3, TDO Output Timing. The TDO is at high impedance, except with shift-DR and shift-IR states. During the change to TRST = 0, there is a transition to test-logic-reset asynchronously with TCK. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2741 of 3088 SH7268 Group, SH7269 Group Section 50 User Debugging Interface 50.5.2 Reset Configuration Table 50.7 Reset Configuration ASEMD* RES TRST Chip State H L L Power-on reset and the reset of this module H Power-on reset L Reset this module only H Normal operation L Reset hold* H Power-on reset L Reset this module only H Normal operation 1 H L L H 2 Notes: 1. Performs product chip mode and ASE mode settings ASEMD = H, normal mode ASEMD = L, ASE mode 2. In ASE mode, reset hold is entered if the TRST pin is driven low while the RES pin is negated. In this state, the CPU does not start up. When TRST is driven high, the operation of this module is enabled, but the CPU does not start up. The reset hold state is cancelled by a power-on reset. 50.5.3 TDO Output Timing When the emulation TAP controller is selected, a transition on the TDO pin is output on the falling edge of TCK with the initial value. However, setting a TDO transition timing switching command in SDIR via the pin and passing the Update-IR state synchronizes the TDO transition with the rising edge of TCK. This command does not affect the output timing of the boundary scan TAP controller. To synchronize the transition of TDO with the falling edge of TCK after setting the TDO transition timing switching command, the TRST pin must be asserted simultaneously with the power-on reset. In the case of power-on reset by the RES pin, the sync reset is still in operation for a certain period in the LSI even after the RES pin is negated. Thus, if the TRST pin is asserted immediately after the negation of the RES pin, the TDO transition timing switching command is cleared, resulting in TDO transitions synchronized with the falling edges of TCK. To prevent this, make sure to allow a period of 20 tcyc or longer between the signal transitions of the RES and TRST pins.

A user debugging interface reset is of the same kind as a power-on reset. A user debugging interface reset is cleared by setting a user debugging interface reset negate command. The required time between the user debugging interface reset assert command and user debugging interface reset negate command is the same as time for keeping the RES pin low to apply a poweron reset.

A user debugging interface interrupt is a general exception/interrupt operation, resulting in fetching the exception service routine start address from the exception handling vector table, jumping to that address, and starting program execution from that address. This interrupt request has a fixed priority level of 15. User debugging interface interrupts are accepted in sleep mode, but not in software standby mode. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2743 of 3088 Section 50 User Debugging Interface 50.6 SH7268 Group, SH7269 Group Boundary Scan By setting the commands in BSIR by this module, pins can be configured for boundary scan mode defined by JTAG. 50.6.1 Supported Instructions This LSI supports three required instructions (BYPASS, SAMPLE/PRELOAD, and EXTEST) and three optional instructions (IDCODE, CLAMP, and HIGHZ) defined by JTAG. (1) BYPASS The BYPASS instruction is a required standard instruction to operate the bypass register. This instruction is used to increase the transfer speed of serial data of other LSIs on the printed circuit board by reducing the shift path. During execution of this instruction, the test circuit does not affect the system circuit. (2) SAMPLE/PRELOAD The SAMPLE/PRELOAD instruction inputs a value from the internal circuit of the LSI to the boundary scan register, and output the data from scan path or load the data to the scan path. During execution of the instruction, the value on the input pin of the LSI is transferred to the internal circuit and the value of the internal circuit is output externally from the output pin. Execution of the instruction does not affect the system circuit of the LSI. In SAMPLE operation, the snapshots of the value transferred from the input pin to the internal circuit and the value transferred from the internal circuit to the output pin are captured in the boundary scan register and then read from the scan path. Capturing of the snapshots is performed in synchronization with the rising edge of TCK in the capture-DR state. The capturing is performed without interfering with normal operation of the LSI. In PRELOAD operation, an initial value is set in the output latch of the boundary scan register from the scan path before execution of the EXTEST instruction. Without PRELOAD operation, an undefined value is output from the output pin until the first scan sequence is completed (transferred to the output latch) during execution of the EXTEST instruction (the parallel output latch is always output to the output pin with the EXTEST instruction). Page 2744 of 3088 R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 SH7268 Group, SH7269 Group (3) Section 50 User Debugging Interface EXTEST The EXTEST instruction tests the external circuit when this LSI is mounted on the printed circuit board. During execution of this instruction, the output pin is used to output the test data (set in advance by the SAMPLE/PRELOAD instruction) from the boundary scan register to the printed circuit board and the input pin is used to capture the test result from the printed circuit board to the boundary scan register. When a test is performed using the EXTEST instruction N times, the N-th test data is scanned-in during (N-1)-th scan-out. The data loaded in the boundary scan register of the output pin in the capture-DR state of this instruction is not used in testing of the external circuit (an exchange is made in shift operation). (4) IDCODE Setting a command to SDIR can set pins to IDCODE mode that is defined by JTAG. When this module is initialized (TRST is asserted or TAP is placed in the test-logic-reset state), IDCODE mode is entered. (5) CLAMP and HIGHZ Setting a command to SDIR can set pins to CLAMP/HIGHZ mode that is defined by JTAG. When this module is initialized (TRST is asserted or TAP is placed in the test-logic-reset state), IDCODE mode is entered. 50.6.2 Notes 1. The clock related signals (EXTAL, XTAL, CKIO, AUDIO_X1, AUDIO_X2, USB_X1, USB_X2, RTC_X1, RTC_X2, and MD_CLK0) are inapplicable to the boundary scan. 2. The reset-related signal (RES) is inapplicable to the boundary scan. 3. Related signals (TCK, TDI, TDO, TMS, TRST, and ASEMD) of this module are inapplicable to the boundary scan. 4. The USB related signals (DP, DM, VBUS, and REFRIN) are inapplicable to the boundary scan. 5. Execute the boundary scan in product chip mode and input the ASEMD pin to high during the RES pin assertion period. And make sure to fix the ASEMD pin at high while executing the boundary scan. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2745 of 3088 Section 50 User Debugging Interface 50.7 SH7268 Group, SH7269 Group Usage Notes 1. Once a command of this module has been set, it will not be modified until another command is not set again. If the same command is to be set continuously, the command must be set after a command (BYPASS mode, etc.) that does not affect chip operations is once set. 2. In software standby mode and in this module's standby state, none of the functions of this module can be used. To retain the TAP status before and after standby mode, keep TCK high before entering standby mode. 3. Regardless of whether this module is used, make sure to keep the TRST pin low to initialize this module at power-on or in recovery from deep standby by the RES pin assertion. 4. If the TRST pin is asserted immediately after the setting of the TDO transition timing switching command and the negation of the RES pin, the TDO transition timing switching command is cleared. To avoid this case, make sure to put 20 tcyc or longer between the signal transition timing of the RES and TRST pins. For details, see section 50.5.3, TDO Output Timing. 5. When starting the TAP controller after the negation of the TRST pin, make sure to allow 200 ns or longer after the negation. 6. Please keep TMS pin high for 200 ns from TRST pin negation.

Register Addresses (by functional module, in order of the corresponding section numbers) * Registers are described by functional module, in order of the corresponding section numbers. * Access to reserved addresses which are not described in this register address list is prohibited. * When registers consist of 16 or 32 bits, the addresses of the MSBs are given when big endian mode is selected. * An asterisk (*) in the column "Access Size" indicates that the unit of access in reading differs from that in writing for the given register. For details, see the register descriptions in the relevant section. 2. Register Bits * Bit configurations of the registers are described in the same order as the Register Addresses (by functional module, in order of the corresponding section numbers). * Reserved bits are indicated by "--" in the bit name. * No entry in the bit-name column indicates that the whole register is allocated as a counter or for holding data. 3. Register States in Each Operating Mode * Register states are described in the same order as the Register Addresses (by functional module, in order of the corresponding section numbers). * For the initial state of each bit, refer to the description of the register in the corresponding section. * The register states described are for the basic operating modes. If there is a specific reset for an on-chip peripheral module, refer to the section on that on-chip peripheral module. R01UH0048EJ0200 Rev. 2.00 Sep 26, 2012 Page 2747 of 3088 Section 51 List of Registers SH7268 Group, SH7269 Group 4. Notes when Writing to the On-Chip Peripheral Modules * To access an on-chip module register, two or more peripheral module clock (P) cycles are required. When the CPU writes data to the internal peripheral registers, the CPU performs the succeeding instructions without waiting for the completion of writing to registers. For example, a case is described here in which the system is transferring to the software standby mode for power savings. To make this transition, the SLEEP instruction must be performed after setting the STBY bit in the STBCR register to 1. However a dummy read of the STBCR register is required before executing the SLEEP instruction. If a dummy read is omitted, the CPU executes the SLEEP instruction before the STBY bit is set to 1, thus the system enters sleep mode not software standby mode. A dummy read of the STBCR register is indispensable to complete writing to the STBY bit. To reflect the change by internal peripheral registers while performing the succeeding instructions, execute a dummy read of registers to which write instruction is given and then perform the succeeding instructions.

After the chip has shifted to the power-on reset state from deep standby mode by the input on any of pins NMI, PC8 to PC5, PJ3, and PJ1, the pins retain the state until the IOKEEP bit in the deep standby cancel source flag register (DSFR) is cleared (see section 49, Power-Down Modes). 3. The EBUSKEEPE bit in deep standby control register (DSTCR) (see section 49, PowerDown Modes). 4. This LSI enters the power-on reset state for a certain period after recovery from deep standby control mode (see section 49, Power-Down Modes). 5. Depends on the setting of the RCKSEL bit in the realtime clock control register 5 (RCR5) (see section 15, Realtime Clock). 6. When pins for the connection with a crystal resonator are not used, the input pins (EXTAL, RTC_X1, AUDIO_X1, USB_X1, and VIDEO_X1) must be fixed (pull-up/down resistor, power supply, or ground.) and the output pins (XTAL, RTC_X2, AUDIO_X2, USB_X2, and VIDEO_X2) must be open. 7. Depends on the setting of the CKOEN bit in the frequency control register (FRQCR) of the clock pulse generator (see section 5, Clock Pulse Generator). 8. Depends on the setting of the AXTALE bit in the software reset control register (SWRSTCR) (see section 49, Power-Down Modes). 9. Depends on the setting of the HIZ bit in the standby control register 3 (STBCR3) (see section 49, Power-Down Modes). 10. Depends on the setting of the HIZMEM bit in the common control register (CMNCR) of the bus state controller (see section 10, Bus State Controller). 11. Depends on the setting of the HIZCNT bit in the common control register (CMNCR) of the bus state controller (see section 10, Bus State Controller). 12. Depends on the setting of the corresponding bit in the deep standby cancel source select register (DSSSR) (see section 49, Power-Down Modes). 13. Depends on the setting of the RTCEN bit in the realtime clock control register 2 (RCR2) (see section 15, Realtime Clock). 14. Z when the TAP controller of the user debugging interface is neither the Shift-DR nor Shift-IR state. 15. These are the pin states in product chip mode (ASEMD = H). See the Emulation Manual for the pin states in ASE mode (ASEMD = L). 16. When this is an output, the output is fixed to either the High or Low level. There is no oscillation.
