Rev. 3.00 Sep. 28, 2009 Page ii of xxx REJ09B0313-0300 General Precautions in the Handling of MPU/MCU Products The following usage notes are applicable to all MPU/MCU products from Renesas. For detailed usage notes on the products covered by this manual, refer to the relevant sections of the manual. If the descriptions under General Precautions in the Handling of MPU/MCU Products and in the body of the manual differ from each other, the description in the body of the manual takes precedence. 1. Handling of Unused Pins Handle unused pins in accord with the directions given under Handling of Unused Pins in the manual. The input pins of CMOS products are generally in the high-impedance state. In operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of LSI, an associated shoot-through current flows internally, and malfunctions may occur due to the false recognition of the pin state as an input signal. Unused pins should be handled as described under Handling of Unused Pins in the manual. 2. Processing at Power-on The state of the product is undefined at the moment when power is supplied. The states of internal circuits in the LSI are indeterminate and the states of register settings and pins are undefined at the moment when power is supplied. In a finished product where the reset signal is applied to the external reset pin, the states of pins are not guaranteed from the moment when power is supplied until the reset process is completed. In a similar way, the states of pins in a product that is reset by an on-chip power-on reset function are not guaranteed from the moment when power is supplied until the power reaches the level at which resetting has been specified. 3. Prohibition of Access to Reserved Addresses Access to reserved addresses is prohibited. The reserved addresses are provided for the possible future expansion of functions. Do not access these addresses; the correct operation of LSI is not guaranteed if they are accessed. 4. Clock Signals After applying a reset, only release the reset line after the operating clock signal has become stable. When switching the clock signal during program execution, wait until the target clock signal has stabilized. When the clock signal is generated with an external resonator (or from an external oscillator) during a reset, ensure that the reset line is only released after full stabilization of the clock signal. Moreover, when switching to a clock signal produced with an external resonator (or by an external oscillator) while program execution is in progress, wait until the target clock signal is stable. 5. Differences between Products Before changing from one product to another, i.e. to one with a different type number, confirm that the change will not lead to problems. The characteristics of MPU/MCU in the same group but having different type numbers may differ because of the differences in internal memory capacity and layout pattern. When changing to products of different type numbers, implement a system-evaluation test for each of the products.

Index Rev. 3.00 Sep. 28, 2009 Page iv of xxx REJ09B0313-0300 Preface This LSI is an RISC (Reduced Instruction Set Computer) microcomputer which includes a Renesas Technology-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 30, List of Registers. Rev. 3.00 Sep. 28, 2009 Page v of xxx REJ09B0313-0300 * 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. Rev. 0.50, 10/04, page 416 of 914 (3) Note: The bit names and sentences in the above figure are examples and do not refer to specific data in this manual. Rev. 3.00 Sep. 28, 2009 Page vi of xxx REJ09B0313-0300 * Description of Registers Each register description includes a bit chart, illustrating the arrangement of bits, and a table of bits, describing the meanings of the bit settings. The standard format and notation for bit charts and tables are described below. [Bit Chart] Bit: Initial value: R/W: 15 14 13 12 11 ASID2 ASID1 ASID0 10 9 8 7 6 5 4 Q 3 2 1 0 ACMP2 ACMP1 ACMP0 IFE 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 R/W R/W R/W R/W R/W R R R/W R/W R/W R/W R/W R/W R/W R/W R/W (1) [Table of Bits] Bit (2) (3) (4) (5) Bit Name - - Initial Value R/W 0 0 R R Reserved These bits are always read as 0. 13 to 11 ASID2 to ASID0 All 0 R/W Address Identifier These bits enable or disable the pin function. 10 - 0 R Reserved This bit is always read as 0. 9 - 1 R Reserved This bit is always read as 1. - 0 15 14 Description Note: The bit names and sentences in the above figure are examples, and have nothing to do with the contents of this manual. (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.

The CPU in this LSI is the SH-2A CPU that provides upward compatibility for SH-1, SH-2, and SH-2E CPUs at object code level. It has a RISC-type instruction set and uses a superscalar architecture and a Harvard architecture, which greatly improves instruction execution speed. In addition, the 32-bit internal-bus architecture that is independent from the direct memory access controller (DMAC) enhances data processing power. This CPU brings the user the ability to set up high-performance systems with strong functionality at less expense than was achievable with previous microcontrollers, and is even able to handle realtime control applications requiring highspeed characteristics. This LSI has a floating-point unit (FPU) and cache. In addition, this LSI includes on-chip peripheral functions necessary for system configuration, such as 64-Kbyte RAM for high-speed operation, 16-Kbyte RAM for data retention, a multi-function timer pulse unit 2 (MTU2), a compare match timer (CMT), a realtime clock (RTC), a serial communication interface with FIFO 2 (SCIF), a synchronous serial communication unit (SSU), an I C bus interface 3 (IIC3), a serial sound interface (SSI), a controller area network (RCAN-TL1), an A/D converter, a D/A converter, an AND/NAND flash memory controller (FLCTL), a USB2.0 host/function module (USB), an interrupt controller (INTC), and I/O ports. This LSI also provides an external memory access support function to enable direct connection to various memory devices or peripheral LSIs. These on-chip functions significantly reduce costs of designing and manufacturing application systems. Furthermore, I/O pins in this LSI have weak keeper circuits that prevent the pin voltage from entering an intermediate potential range. Therefore, no external circuits to fix the input level are required, which reduces the parts number considerably. The features of this LSI are listed in table 1.1.

The register set consists of sixteen 32-bit general registers, four 32-bit control registers, and four 32-bit system registers. 2.1.1 General Registers Figure 2.1 shows the general registers. 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. Figure 2.1 General Registers Rev. 3.00 Sep. 28, 2009 Page 47 of 1650 REJ09B0313-0300 Section 2 CPU 2.1.2 Control Registers The control registers consist of four 32-bit registers: the status register (SR), the global base register (GBR), the vector base register (VBR), and the jump table base register (TBR). 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) 0 31 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 - - - - - - - - - - - - - - - - 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: Rev. 3.00 Sep. 28, 2009 Page 48 of 1650 REJ09B0313-0300 I[3:0] 1 R/W 1 R/W 1 R/W 1 R/W 16 Section 2 CPU Bit Bit Name Initial Value 31 to 15 -- All 0 R/W Description R Reserved These bits are always read as 0.

Rev. 3.00 Sep. 28, 2009 Page 49 of 1650 REJ09B0313-0300 Section 2 CPU 2.1.3 System Registers The system registers consist of four 32-bit registers: the high and low multiply and accumulate registers (MACH and MACL), the procedure register (PR), and the program counter (PC). MACH and MACL store the results of multiply or multiply and accumulate operations. PR stores the return address from a subroutine procedure. PC indicates the address four bytes ahead of the instruction being executed 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.

(3) Program Counter (PC) PC indicates the address four bytes ahead of the instruction being executed. Rev. 3.00 Sep. 28, 2009 Page 50 of 1650 REJ09B0313-0300 Section 2 CPU 2.1.4 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 6.8, 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 + 1 Address m 31 Address m + 2 23 Byte Address 2n Address 4n Address m + 3 15 Byte 7 Byte Word 0 Byte Word Longword Figure 2.5 Data Formats in Memory Rev. 3.00 Sep. 28, 2009 Page 52 of 1650 REJ09B0313-0300 Section 2 CPU 2.2.3 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. Rev. 3.00 Sep. 28, 2009 Page 53 of 1650 REJ09B0313-0300 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 instruction. H'1234 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. Rev. 3.00 Sep. 28, 2009 Page 54 of 1650 REJ09B0313-0300 Section 2 CPU (6) 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. Rev. 3.00 Sep. 28, 2009 Page 55 of 1650 REJ09B0313-0300 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.

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.

Instruction execution cycles: The execution cycles shown in the table are minimums. In practice, the number of instruction execution states will be increased in cases such as the following: a. When there is a conflict between an instruction fetch and a data access b. When the destination register of a load instruction (memory register) is the same as the register used by the next instruction. 2. Depending on the operand size, displacement is scaled by x1, x2, or x4. For details, refer to the SH-2A, SH2A-FPU Software Manual.

REJ09B0313-0300 Section 2 CPU 2.5 Processing States The CPU has five processing states: reset, exception handling, bus-released, program execution, and power-down. 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 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 cleared NMI interrupt or IRQ interrupt occurs Exception handling ends Bus request cleared Bus request generated Bus request generated NMI interrupt, IRQ interrupt*, manual reset, and power-on reset Program execution state STBY bit cleared for SLEEP instruction Sleep mode 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 Note: * IRQ can be released only by PE11 to PE4. Figure 2.6 Transitions between Processing States Rev. 3.00 Sep. 28, 2009 Page 90 of 1650 REJ09B0313-0300 Section 2 CPU (1) 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 value of the EN.V bit in FPSCR is 1, FPU exception handling is triggered by an invalid operation exception. 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. The qNAN values as operation results are as follows: * Single-precision qNaN: H'7FBF FFFF * Double-precision qNaN: H'7FF7 FFFF FFFF FFFF See the individual instruction descriptions for details of floating-point operations when a nonnumber (NaN) is input.

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.

The FPU exception flag field bit remains set to 1 until it is cleared to 0 by software. FPU exception handling occurs if the corresponding bit in the FPU exception enable field is set to 1.

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 Rev. 3.00 Sep. 28, 2009 Page 101 of 1650 REJ09B0313-0300 Section 3 Floating-Point Unit (FPU) 3.4 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. Rev. 3.00 Sep. 28, 2009 Page 102 of 1650 REJ09B0313-0300 Section 3 Floating-Point Unit (FPU) 3.5 FPU Exceptions 3.5.1 FPU Exception Sources FPU exceptions may be triggered by floating point operation instructions. 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 Rev. 3.00 Sep. 28, 2009 Page 103 of 1650 REJ09B0313-0300 Section 3 Floating-Point Unit (FPU) The possibilities for exception handling caused by floating point operations are described in the individual instruction descriptions. All exception events that originate in floating point operations are assigned as the same FPU exception handling event. The meaning of an exception caused by a 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 occurs. Except for the above, 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.

The CPG consists of a crystal oscillator, PLL circuits, and divider circuits. 4.1 Features * Four clock operating modes The mode is selected from among the four clock operating modes based on the frequency range to be used and the input clock type: the clock from crystal resonator, the external clock or the clock for USB. * Three clocks generated independently An internal clock (I) for the CPU and cache; a peripheral clock (P) for the on-chip peripheral modules; a bus clock (B = CKIO) for the external bus interface * Frequency change function Internal and peripheral clock frequencies can be changed independently using the PLL (phase locked loop) circuits and divider circuits within the CPG. 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 28, Power-Down Modes.

One of them is selected according to the clock operating mode. (2) Divider 1 Divider 1 divides the output from the crystal oscillator or the external clock input. The division ratio depends on the clock operating mode. (3) PLL Circuit PLL circuit multiplies the frequency of the output from the divider 1. The multiplication ratio is set by the frequency control register. (4) Divider 2 Divider 2 generates a clock signal whose operating frequency can be used for the internal clock, the peripheral clock, and the bus clock. The division ratio of the internal clock and peripheral clock are set by the frequency control register. The division ratio of the bus clock is determined by the clock operating mode and the PLL multiplication ratio. (5) Clock Frequency Control Circuit The clock frequency control circuit controls the clock frequency using the MD_CLK0 and MD_CLK1 pins and the frequency control register (FRQCR). (6) Standby Control Circuit The standby control circuit controls the states of the clock pulse generator 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 28, Power-Down Modes. (7) 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, the frequency multiplication ratio of PLL circuit, and the frequency division ratio of the internal clock and the peripheral clock (P).

The PLL circuit shapes waveform and the frequency is multiplied according to the frequency control register setting before the clock is supplied to the LSI. The frequency range of CKIO is from 40 to 66.66 MHz. To reduce current consumption, fix the EXTAL pin (pull up, pull down, connect to power supply, or connect to ground) and open the XTAL pin when the SH7203 is used in mode 2.

All of these are controlled by software through the frequency control register (FRQCR). The methods are described below. 4.5.1 Changing the Multiplication Rate Oscillation settling time must be provided when the multiplication rate of the PLL circuit is changed. The on-chip WDT counts the settling time. The oscillation settling time is the same as when software standby mode is canceled. 1. In the initial state, the multiplication rate of PLL circuit is 8 time. 2. Set a value that will become the specified oscillation settling time in the WDT and stop the WDT. The following must be set: WTCSR.TME = 0: WDT stops WTCSR.CKS[2:0]: Division ratio of WDT count clock WTCNT counter: Initial counter value (The WDT count is incremented using the clock after the setting.) 3. Set the desired value in the STC1 and STC0 bits. The division ratio can also be set in the IFC and PFC2 to PFC0 bits. 4. This LSI pauses temporarily and the WDT starts incrementing. The internal and peripheral clocks both stop and the WDT is supplied with the clock. The clock will continue to be output at the CKIO pin. This state is the same as software standby mode. Whether or not registers are initialized depends on the module. For details, see section 30.3, Register States in Each Operating Mode. 5. Supply of the clock that has been set begins at WDT count overflow, and this LSI begins operating again. The WDT stops after it overflows. Rev. 3.00 Sep. 28, 2009 Page 116 of 1650 REJ09B0313-0300 Section 4 Clock Pulse Generator (CPG) 4.5.2 Changing the Division Ratio Counting by the WDT does not proceed if the frequency divisor is changed but the multiplier is not. 1. In the initial state, IFC = B'0 and PFC[2:0] = B'011. 2. Set the desired value in the IFC and PFC2 to IFC0 bits. The values that can be set are limited by the clock operating mode and the multiplication rate of PLL circuit. Note that if the wrong value is set, this LSI will malfunction. 3. After the register bits (IFC and PFC2 to PFC0) have been set, the clock is supplied of the new division ratio. Notes: 1. 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. 2. When the frequency-multiplier of the PLL circuit is changed and while oscillation is settling after exit from software standby mode, an unstable CKIO clock will be output in clock mode 0, 1, or 3. Control bits 14, 13, and 12 in FRQCR to ensure that this unstable CKIO clock does not lead to malfunctions.

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.

Table 5.2 Timing of Exception Source Detection and Start of Exception Handling Exception Source Timing of Source Detection and Start of Handling Reset Power-on reset Starts when the RES pin changes from low to high, when the H-UDI reset negate command is set after the H-UDI reset assert command has been set, or when the WDT overflows. Manual reset Starts when the MRES pin changes from low to high or when the WDT overflows. Address error Detected when instruction is decoded and starts when the previous executing instruction finishes executing. Interrupts Detected when instruction is decoded and starts when the previous executing instruction finishes executing. Register bank Bank underflow error Starts upon attempted execution of a RESBANK instruction when saving has not been performed to register banks. Instructions Bank overflow In the state where saving has been performed to all register bank areas, starts when acceptance of register bank overflow exception has been set by the interrupt controller (the BOVE bit in IBNR of the INTC is 1) and an interrupt that uses a register bank has occurred and been accepted by the CPU. Trap instruction Starts from the execution of a TRAPA instruction. General illegal instructions Starts from the decoding of undefined code anytime except immediately after a delayed branch instruction (delay slot) (including FPU instructions and FPU-related CPU instructions in FPU module standby state). 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 exception Starts when detecting division-by-zero exception or overflow exception caused by division of the negative maximum value (H'80000000) by -1. Rev. 3.00 Sep. 28, 2009 Page 125 of 1650 REJ09B0313-0300 Section 5 Exception Handling Exception Source Timing of Source Detection and Start of Handling Instructions FPU exception Starts when detecting invalid operation exception defined by IEEE standard 754, division-by-zero exception, overflow, underflow, or inexact exception. 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 5.1.3, 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. The BN bit in IBNR of the interrupt controller (INTC) 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. (2) 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 or user breaks 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 an address error, register bank error, NMI interrupt, user break interrupt, or instruction, 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 INTC is 0). If a setting to accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the INTC 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.

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. Table 5.3 shows the vector numbers and vector table address offsets. Table 5.4 shows how vector table addresses are calculated.

Table 5.5 Pin Configuration Pin Name Symbol I/O Function Power-on reset RES Input When this pin is driven low, this LSI shifts to the poweron reset processing Manual reset MRES Input When this pin is driven low, this LSI shifts to the manual reset processing. 5.2.2 Types of Reset A reset is the highest-priority exception handling source. There are two kinds of reset, power-on and manual. As shown in table 5.6, 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. Table 5.6 Reset States Conditions for Transition to Reset State Internal States Type RES H-UDI Command MRES WDT Overflow CPU Other Modules Power-on reset Low -- -- -- Initialized Initialized High H-UDI reset assert command is set -- -- Initialized Initialized High Command other than H-UDI reset assert is set -- Power-on reset Initialized * High Command other than H-UDI reset assert is set Low -- Initialized * High Command other than H-UDI reset assert is set High Manual reset Initialized * Manual reset Note: * See section 30.3, Register States in Each Operating Mode. Rev. 3.00 Sep. 28, 2009 Page 129 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.2.3 (1) Power-On Reset Power-On Reset by Means of RES Pin When the RES pin is driven low, this LSI enters the power-on reset state. 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 (unfixed) 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 appendix A, 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. The BN bit in IBNR of the INTC 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 H-UDI Reset Assert Command When the H-UDI reset assert command is set, this LSI enters the power-on reset state. Power-on reset by means of an H-UDI reset assert command is equivalent to power-on reset by means of the RES pin. Setting the H-UDI reset negate command cancels the power-on reset state. The time required between an H-UDI reset assert command and H-UDI 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 an H-UDI reset assert command, setting the H-UDI 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. Rev. 3.00 Sep. 28, 2009 Page 130 of 1650 REJ09B0313-0300 Section 5 Exception Handling (3) Power-On Reset Initiated by WDT When a setting is made for a power-on reset to be generated in the WDT's watchdog timer mode, and WTCNT of the WDT overflows, this LSI enters the power-on reset state. In this case, WRCSR of the WDT and FRQCR of the CPG are not initialized by the reset signal generated by the WDT. If a reset caused by the RES pin or the H-UDI reset assert command occurs simultaneously with a reset caused by WDT overflow, the reset caused by the RES pin or the H-UDI 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 WDT, the CPU operates in the same way as when a poweron reset was caused by the RES pin. Rev. 3.00 Sep. 28, 2009 Page 131 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.2.4 (1) Manual Reset Manual Reset by Means of MRES Pin When the MRES pin is driven low, this LSI enters the manual reset state. To reset this LSI without fail, the MRES pin should be kept at the low level for at least 20-tcyc. In the manual reset state, the CPU's internal state is initialized, but all the on-chip peripheral module registers are not initialized. In the manual reset state, manual reset exception handling starts when the MRES 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. The BN bit in IBNR of the INTC 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. (2) Manual Reset Initiated by WDT When a setting is made for a manual reset to be generated in the WDT's watchdog timer mode, and WTCNT of the WDT overflows, this LSI enters the manual reset state. When manual reset exception processing is started by the WDT, the CPU operates in the same way as when a manual reset was caused by the MRES pin. (3) Note in Manual Reset When a manual reset is generated, the bus cycle is retained, but if a manual reset occurs while the bus is released or during DMAC burst transfer, manual reset exception handling will be deferred until the CPU acquires the bus. The CPU and the BN bit in IBNR of the INTC are initialized by a manual reset. The FPU and other modules are not initialized.

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. Note: * In the case of an address error caused by a data read or write, if the address error is caused by an instruction fetch and the bus cycle in which the address error occurred has not ended by the end of the above operation, the CPU restarts address error exception handling before the bus cycle ends.

(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. 5.4.2 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. To prevent multiple interrupts from occurring at a bank overflow, the interrupt priority level 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.

Rev. 3.00 Sep. 28, 2009 Page 136 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.5.2 Interrupt Priority Level The interrupt priority order is predetermined. When multiple interrupts occur simultaneously (overlap), the interrupt controller (INTC) determines their relative priorities and starts processing 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 user break interrupt and H-UDI interrupt priority level 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 17 (IPR01, IPR02, and IPR05 to IPR17) of the INTC as shown in table 5.9. The priority levels that can be set are 0 to 15. Level 16 cannot be set. See section 6.3.1, Interrupt Priority Registers 01, 02, 05 to 17 (IPR01, IPR02, IPR05 to IPR17), for details of IPR01, IPR02, and IPR05 to IPR17. Table 5.9 Interrupt Priority Order Type Priority Level Comment NMI 16 Fixed priority level. Cannot be masked. User break 15 Fixed priority level. H-UDI 15 Fixed priority level. IRQ 0 to 15 Set with interrupt priority registers 01, 02, and 05 to 17 (IPR01, IPR02, and IPR05 to IPR17). PINT On-chip peripheral module Rev. 3.00 Sep. 28, 2009 Page 137 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.5.3 Interrupt Exception Handling When an interrupt occurs, its priority level is ascertained by the interrupt controller (INTC). 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 or user breaks 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 an address error, NMI interrupt, user break interrupt, or instruction, 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 INTC is 0). If a setting to accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the INTC 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 6.6, Operation, for further details of interrupt exception handling.

Table 5.10 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.

Rev. 3.00 Sep. 28, 2009 Page 139 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.6.2 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. 5.6.3 Slot Illegal Instructions An instruction placed immediately after a delayed branch instruction is said to be 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. Rev. 3.00 Sep. 28, 2009 Page 140 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.6.4 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. 5.6.5 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. Rev. 3.00 Sep. 28, 2009 Page 141 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.6.6 FPU Exceptions FPU exception handling takes place when the V, Z, O, U, or I bit in the FPU enable field (Enable) of the floating point status/control register (FPSCR) is set to 1. This indicates the occurrence of an invalid operation exception defined by the IEEE 754 standard, a division-by-zero exception, an overflow (in the case of an instruction for which this is possible), an underflow (in the case of an instruction for which this is possible), or an inexact exception (in the case of an instruction for which this is possible). The instructions that may trigger FPU exception handling are FADD, FSUB, FMUL, FDIV, FMAC, FCMP/EQ, FCMP/GT, FLOAT, FTRC, FCNVDS, FCNVSD, and FSQRT. FPU exception handling occurs only when the corresponding FPU exception enable bit (Enable) is set to 1. When an exception source triggered by a floating-point operation is detected, FPU operation is halted and the occurrence of FPU exception handling is reported to the CPU. When exception handling starts, the CPU operates 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 on the stack. 3. The program counter (PC) is saved on 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 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 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 instruction is executed. When the V bit in the FPU exception enable field (Enable) of FPSCR and the QIS bit in FPSCR are both set to 1, FPU exception handling occurs when qNAN or is input to a floating-point operation instruction source. Rev. 3.00 Sep. 28, 2009 Page 142 of 1650 REJ09B0313-0300 Section 5 Exception Handling 5.7 When Exception Sources Are Not Accepted When an address error, FPU exception, register bank error (overflow), or interrupt is generated immediately after a delayed branch instruction, it is sometimes not accepted immediately but stored instead, as shown in table 5.11. 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. 5.9.2 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. 5.9.3 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.

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.

The INTC registers set the order of priority of each interrupt, allowing the user to process interrupt requests according to the user-set priority. 6.1 Features * 16 levels of interrupt priority can be set By setting the fifteen 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. * Occurrence of interrupt can be reported externally (IRQOUT pin) For example, when this LSI has released the bus mastership, this LSI can inform the external bus master of occurrence of an on-chip peripheral module interrupt and request for the bus mastership. * Register banks This LSI has register banks that enable register saving and restoration required in the interrupt processing to be performed at high speed.

Rev. 3.00 Sep. 28, 2009 Page 164 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 6.4 Interrupt Sources There are six types of interrupt sources: NMI, user break, H-UDI, 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. 6.4.1 NMI Interrupt The NMI interrupt has a priority level of 16 and is accepted at all times. NMI interrupt requests are edge-detected, and the NMI edge select bit (NMIE) in interrupt control register 0 (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. 6.4.2 User Break Interrupt A user break interrupt which occurs when a break condition set in the user break controller (UBC) 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 7, User Break Controller (UBC). 6.4.3 H-UDI Interrupt The user debugging interface (H-UDI) interrupt has a priority level of 15, and occurs at serial input of an H-UDI interrupt instruction. H-UDI interrupt requests are edge-detected and retained until they are accepted. The H-UDI interrupt exception handling sets the I3 to I0 bits in SR to level 15. For H-UDI interrupts, see section 29, User Debugging Interface (H-UDI). 6.4.4 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 INTC while the IRQ7 to IRQ0 pins are low. An interrupt request signal is stopped being sent to the INTC when the IRQ7 to IRQ0 pins are driven high. The status of the interrupt requests can be Rev. 3.00 Sep. 28, 2009 Page 165 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 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 INTC. 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. 6.4.5 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 INTC while the PINT7 to PINT0 pins are low. An interrupt request signal is stopped being sent to the INTC 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 highlevel 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 17 (IPR05 to IPR17). 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. Rev. 3.00 Sep. 28, 2009 Page 167 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 6.5 Interrupt Exception Handling Vector Table and Priority Table 6.4 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 5.4. 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 17 (IPR01, IPR02, and IPR05 to IPR17). However, if two or more interrupts specified by the same IPR among IPR05 to IPR17 occur, the priorities are defined as shown in the IPR setting unit internal priority of table 6.4, 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 6.4.

177 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 6.6 Operation 6.6.1 Interrupt Operation Sequence The sequence of interrupt operations is described below. Figure 6.2 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 17 (IPR01, IPR02, and IPR05 to IPR17). 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 6.4. 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. When the interrupt controller accepts an interrupt, a low level is output from the IRQOUT pin. 5. 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 6.4). 6. The interrupt exception service routine start address is fetched from the exception handling vector table corresponding to the accepted interrupt. 7. 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. 8. The program counter (PC) is saved onto the stack. 9. 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. 10. A high level is output from the IRQOUT pin. However, if the interrupt controller accepts an interrupt with a higher priority than the interrupt just being accepted, the IRQOUT pin holds low level. Rev. 3.00 Sep. 28, 2009 Page 178 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 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 6.5 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 6.4.4, IRQ Interrupts. Interrupts held pending due to edge-sensing are cleared by a power-on reset.

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.

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.

Rev. 3.00 Sep. 28, 2009 Page 190 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 6.8.3 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. Rev. 3.00 Sep. 28, 2009 Page 191 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 6.8.4 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. 6.8.5 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. Rev. 3.00 Sep. 28, 2009 Page 192 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 6.9 Data Transfer with Interrupt Request Signals Interrupt request signals can be used to activate the DMAC and transfer data. Interrupt sources that are designated to activate the DMAC are masked without being input to the INTC. 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) Figure 6.13 shows a block diagram of interrupt control. Here, DME is bit 0 in DMAOR of the DMAC, and DEn (n = 0 to 7) is bit 0 in CHCR0 to CHCR7 of the DMAC. For details, see section 10, Direct Memory Access Controller (DMAC).

If, DMAC activating sources are selected, clear the DE bit to 0 for the relevant channel of the DMAC. 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. 6.9.2 Handling Interrupt Request Signals as Sources for Activating DMAC but Not CPU Interrupt 1. Select DMAC 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 DMAC when interrupts occur. 3. The DMAC clears the interrupt sources when starting transfer. Rev. 3.00 Sep. 28, 2009 Page 194 of 1650 REJ09B0313-0300 Section 6 Interrupt Controller (INTC) 6.10 Usage Note 6.10.1 Timing to Clear an Interrupt Source 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 6.5 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 interrupt source flag, read the flag three times after clearing it. 6.10.2 Timing of IRQOUT Negation Once the interrupt controller has accepted an interrupt request, the low level is output from the IRQOUT pin until the CPU jumps to the first address of the interrupt exception service routine, after which the high level is output from the IRQOUT pin. If, however, the interrupt controller has accepted an interrupt request and the low level is being output from the IRQOUT pin, but the interrupt request is canceled before the CPU has jumped to the first address of the interrupt exception service routine, the low level continues to be output from the IRQOUT pin until the CPU has jumped to the first address of the interrupt exception service routine for the next interrupt request.

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 DMAC) 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 the UBC. 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 DMA issues bus cycles. The UBC monitors the C bus and I bus. 7.1 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.

Rev. 3.00 Sep. 28, 2009 Page 209 of 1650 REJ09B0313-0300 Section 7 User Break Controller (UBC) 7.4 Operation 7.4.1 Flow of the User Break Operation 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, the UBC sends a user break interrupt request to the INTC, 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 INTC 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 6, Interrupt Controller (INTC). 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 INTC, 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 8.8. Rev. 3.00 Sep. 28, 2009 Page 210 of 1650 REJ09B0313-0300 Section 7 User Break Controller (UBC) 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. 7.4.2 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. Rev. 3.00 Sep. 28, 2009 Page 211 of 1650 REJ09B0313-0300 Section 7 User Break Controller (UBC) 7.4.3 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 7.4.1, 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 7.3. Table 7.3 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. When C bus/data access cycle or I bus/data access cycle is specified as a break condition: The address after executing several instructions of the instruction that matched the break condition is saved to the stack.

Rev. 3.00 Sep. 28, 2009 Page 216 of 1650 REJ09B0313-0300 Section 7 User Break Controller (UBC) 7.5 Usage Notes 1. The CPU can read from or write to the UBC registers via the internal CPU bus. Accordingly, during the period from executing an instruction to rewrite the UBC register till the new value is actually rewritten, the desired break may not occur. In order to know the timing when the UBC register is changed, read from the last written register. Instructions after then are valid for the newly written register value. 2. The UBC 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 5.1 in section 5, 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 UBC module standby mode. Do not read from or write to the UBC registers during UBC 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. Each of the address and data sections is divided into 128 entries per way. 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 8.1 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 external memory access. 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 9, Bus State Controller (BSC)), 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. Rev. 3.00 Sep. 28, 2009 Page 220 of 1650 REJ09B0313-0300 Section 8 Cache (3) 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 8.1 when the cache lock function (only for operand cache) is not used (concerning the case where the cache lock function is used, see section 8.2.2, Cache Control Register 2 (CCR2)). If a bit pattern other than those listed in table 8.1 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 8.1. 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 8.3. 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 8.4. 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. 8.3.1 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 8.2 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 8.2 shows a hit on way 1.

LRU is updated so that the hit way is the latest. (2) Read Miss An external bus cycle starts and the entry is updated. The way replaced follows table 8.4. Entries are updated in 16-byte units. When the desired data that caused the miss is loaded from external memory 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 write-back 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 updates and write-backs to memory are performed in wrap-around fashion. For example, if the value of the lower four bits of an address that triggers a read miss is H'4, the value of the lower four address bits changes from H'4 to H'8, H'C, and H'0, in that order, when cache updates or write-backs are performed. 8.3.3 (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 8.3. Other operations are the same in case of read miss. Rev. 3.00 Sep. 28, 2009 Page 230 of 1650 REJ09B0313-0300 Section 8 Cache 8.3.4 (1) 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 external memory write cycle 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 an external memory write cycle 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 external bus cycle starts when a write miss occurs, and the entry is updated. The way to be replaced follows table 8.4. 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 updates and write-backs to memory are performed in wrap-around fashion. For example, if the value of the lower four bits of an address that triggers a write miss is H'4, the value of the lower four address bits changes from H'4 to H'8, H'C, and H'0, in that order, when cache updates or write-backs are performed. In write-through mode, no write to cache occurs in a write miss; the write is only to the external memory. 8.3.5 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. 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 external memory. 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 8.3 shows the configuration of the write-back buffer. A (31 to 4) Longword 0 Longword 1 Longword 2 Longword 3 A (31 to 4): Physical address written to external memory (upper three bits are 0) Longword 0 to 3: One line of cache data to be written to external memory Figure 8.3 Write-Back Buffer Configuration Rev. 3.00 Sep. 28, 2009 Page 231 of 1650 REJ09B0313-0300 Section 8 Cache Operations in sections 8.3.2 to 8.3.5 are summarized in table 8.8.

When memory shared by this LSI and another device is mapped in the cache-enabled space, operate the memorymapped cache to invalidate and write back as required. Rev. 3.00 Sep. 28, 2009 Page 233 of 1650 REJ09B0313-0300 Section 8 Cache 8.4 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'F000 0000 to H'F07F FFFF, and the data array onto addresses H'F100 0000 to H'F17F FFFF. The operand cache address array is mapped onto addresses H'F080 0000 to H'F0FF FFFF, and the data array onto addresses H'F180 0000 to H'F1FF FFFF. Only longword can be used as the access size for the address array and data array, and instruction fetches cannot be performed. 8.4.1 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 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 8.4. 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. When Rev. 3.00 Sep. 28, 2009 Page 234 of 1650 REJ09B0313-0300 Section 8 Cache memory write-backs are performed, the value of the lower four address bits changes from H'0 to H'4, H'8, and H'C, in that order. (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. When memory write-backs are performed, the value of the lower four address bits changes from H'0 to H'4, H'8, and H'C, in that order. 8.4.2 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 8.4. 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. Rev. 3.00 Sep. 28, 2009 Page 235 of 1650 REJ09B0313-0300 Section 8 Cache (2) Data Array Write The longword data specified by the data is written to the position specified by the L bit in the address from the entry address specified by the address and the entry corresponding to the way. 1.

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 8.4 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 Rev. 3.00 Sep. 28, 2009 Page 237 of 1650 REJ09B0313-0300 Section 8 Cache 8.4.4 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 DMAC.

BSC functions enable this LSI to connect directly with SRAM, SDRAM, and other memory storage devices, and external devices. 9.1 Features 1. External address space A maximum of 64 Mbytes for each of areas CS0 to CS7. Can specify the normal space interface, SRAM interface with byte selection, burst ROM (clocked synchronous or asynchronous), MPX-I/O, burst MPX-I/O, SDRAM, and PCMCIA interface for each address space. Can select the data bus width (8, 16, or 32 bits) for each address space. Controls insertion of wait cycles for each address space. Controls insertion of wait cycles for each read access and write access. Can set independent idle cycles during the continuous access for five cases: read-write (in same space/different spaces), read-read (in same space/different spaces), the first cycle is a write access. 2. Normal space interface Supports the interface that can directly connect to the SRAM. 3. Burst ROM interface (clocked asynchronous) High-speed access to the ROM that has the page mode function. 4. MPX-I/O interface Can directly connect to a peripheral LSI that needs an address/data multiplexing. 5. SDRAM interface Can set the SDRAM in up to two areas. Multiplex output for row address/column address. Efficient access by single read/single write. High-speed access in bank-active mode. Supports an auto-refresh and self-refresh. Supports low-frequency and power-down modes. Issues MRS and EMRS commands. Rev. 3.00 Sep. 28, 2009 Page 239 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) 6. PCMCIA direct interface Supports the IC memory card and I/O card interface defined in JEIDA specifications Ver. 4.2 (PCMCIA2.1 Rev. 2.1). Wait-cycle insertion controllable by program. 7. SRAM interface with byte selection Can connect directly to a SRAM with byte selection. 8. Burst MPX-I/O interface Can connect directly to a peripheral LSI that needs an address/data multiplexing.

External address spaces CS0 to CS7 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 30, List of Registers. Do not access addresses which are not described in these sections. Otherwise, the correct operation cannot be guaranteed. Data Bus Width and Pin Function Setting in Each Area In this LSI, the data bus width of area 0 and the initial data bus width of areas 1 to 7 can be set to 16, or 32 bits through external pins during a power-on reset. The bus width of area 0 cannot be modified after a power-on reset. The initial data bus width of areas 1 to 7 is set to the same size as that of area 0, but can be modified to 8, 16, or 32 bits through register settings during program execution. Note that the selectable data bus widths may be limited depending on the connected memory type. After a power-on reset, the LSI starts execution of the program stored in the external memory allocated in area 0. Since ROM is assumed as the external memory in area 0, minimum pin functions such as the address bus, data bus, CS0, and RD are available. The sample access waveforms shown in this section include other pins such as BS, RD/WR, and WEn, which are available after they are selected through the pin function controller. Do not attempt any form of memory access other than reading of area 0 until the pin function settings have been completed by the program. When the LSI has been started up with a 32-bit bus and the bus width of an area other than area 0 is changed to 16 bits, the A1 pin setting becomes necessary for access to that area. In the same way, both A1 and A0 pin settings become necessary when the bus width of an area is changed to 8 bits. When area 7 is in use, the CS7 and A0 functions are assigned to the same pin. In this case, therefore, note that the 8-bit bus width is not selectable. For details on pin function settings, see section 25, Pin Function Controller (PFC).

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. The REFOUT signal can be asserted when a refresh request is generated while the bus is released. For details, see the description of Relationship between Refresh Requests and Bus Cycles in section 9.5.6 (9), Relationship between Refresh Requests and Bus Cycles, and section 9.5.13, Bus Arbitration. 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. Little endian cannot be selected for area 0. However, the endian of areas 1 to 7 can be changed by the setting in the CSnBCR register setting as long as the target space is not being accessed. Three data bus widths (8 bits, 16 bits, and 32 bits) are selectable for areas 1 to 7, allowing the connection of normal memory and of SRAM with byte selection. Two data bus widths (16 bits and 32 bits) are available 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 can be fixed to either 8 or 16 bits, or made selectable as 8 bits or 16 bits by one of the address lines. The data bus width for burst MPX-I/O is fixed at 32 bits. Data alignment is in accord 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. The data bus width of area 0 is fixed to 16 bits or 32 bits by the MD pin setting at a power-on reset. Tables 9.5 to 9.10 show the relationship between device data width and access unit. Note that the correspondence between addresses and strobe signals for the 32- and 16-bit bus widths depends on the endian setting. For example, with big endian and a 32-bit bus width, WE3 corresponds to the 0th address, which is represented by WE0 when little endian has been selected. Area 0 cannot be set to little endian mode. In addition, fetching instructions from a little endian area can be difficult because 32-bit and 16-bit accesses are mixed, so big endian mode should be used for instruction execution.

When using SRAM with a byte-selection pin, see section 9.5.8, SRAM Interface with Byte Selection. Figure 9.2 shows the basic timings of normal space access.

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, to avoid collision. Figures 9.3 and 9.4 show the basic timings of normal space access. 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 9.3). If the WM bit in CSnWCR is set to 1, external waits are ignored and no Tnop cycle is inserted (figure 9.4).

It is possible for areas 1, 4, 5, and 7 to insert wait cycles independently in read access and in write access. Areas 0, 2, 3, and 6 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 9.10 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. Timing charts are shown in figures 9.11 to 9.13.

The control signals for direct connection of SDRAM are RASU, RASL, CASU, CASL, 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 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 can be set to 32 or 16 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 RASU, RASL, CASU, CASL, 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 9.5.1, Endian/Access Size and Data Alignment. Figures 9.14 to 9.16 show examples of the connection of the SDRAM with the LSI. Rev. 3.00 Sep. 28, 2009 Page 316 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) As shown in figure 9.16, two sets of SDRAMs of 32 Mbytes or smaller can be connected to the same CS space by using RASU, RASL, CASU, and CASL. In this case, a total of 8 banks are assigned to the same CS space: 4 banks specified by RASL and CASL, and 4 banks specified by RASU and CASU. When accessing the address with A25 = 0, RASL and CASL are asserted. When accessing the address with A25 = 1, RASU and CASU are asserted. 64M SDRAM (1M x 16-bit x 4-bank) This LSI A13 ... ... A15 ...

Tables 9.11 to 9.16 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), the A0 pin 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.

Rev. 3.00 Sep. 28, 2009 Page 331 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) (3) Burst Read A burst read occurs in the following cases with this LSI. * Access size in reading is larger than data bus width. * 16-byte transfer in cache miss. * 16-byte transfer by DMAC * 16-byte to 128-byte transfer by LCDC This LSI always accesses the SDRAM with burst length 1. For example, read access of burst length 1 is performed consecutively 4 times to read 16-byte continuous data from the SDRAM that is connected to a 32-bit data bus. This access is called the burst read with the burst number 4. Table 9.17 shows the relationship between the access size and the number of bursts. Note: For details, see section 24, LCD Controller (LCDC).

For details, see section 24, LCD Controller (LCDC). Rev. 3.00 Sep. 28, 2009 Page 332 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) Figures 9.17 and 9.18 show a timing chart 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 9.18 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 NOT 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 and WTRCD0 bit 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 4 times to write 16-byte continuous data to the SDRAM that is connected to a 32-bit data bus. This access is called burst write with the burst number 4. The relationship between the access size and the number of bursts is shown in table 9.17. Figure 9.20 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 either the upper or lower bits of 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 or both the upper and lower bits of area 3 are connected 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 9.22, a burst read cycle for the same row address in figure 9.23, and a burst read cycle for different row addresses in figure 9.24. Similarly, a burst write cycle without auto-precharge is shown in figure 9.25, a burst write cycle for the same row address in figure 9.26, and a burst write cycle for different row addresses in figure 9.27. In figure 9.23, 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 Rev. 3.00 Sep. 28, 2009 Page 340 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) 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. 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 9.22 or 9.25, followed by repetition of the cycle in figure 9.23 or 9.26. 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 9.24 or 9.27 is executed instead of that in figure 9.23 or 9.26. 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.

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. (a) 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, 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 9.28 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 9.29. 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, or when exiting standby mode other than through a power-on reset, auto-refreshing is restarted if the RFSH bit is set to 1 and the RMODE bit is cleared to 0 when self-refresh mode is cleared. If the transition from clearing of self-refresh mode to the start of auto-refreshing 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 4, Clock Pulse Generator (CPG). The contents of SDRAM can be retained by placing the SDRAM in the selfrefresh 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. This LSI has the REFOUT pin to request the bus while waiting for refresh execution. For REFOUT pin function selection, see section 25, Pin Function Controller (PFC). This LSI continues to assert REFOUT (low level) until the bus is acquired. On receiving the asserted REFOUT signal, the external device must negate the BREQ signal and return the bus. 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. Rev. 3.00 Sep. 28, 2009 Page 351 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) (10) Low-Frequency Mode When the SLOW bit in SDCR is set to 1, output of commands, addresses, and write data, and fetch of read data are performed at a timing suitable for operating SDRAM at a low frequency. Figure 9.30 shows the access timing in low-frequency mode. In this mode, commands, addresses, and write data are output in synchronization with the falling edge of CKIO, which is half a cycle delayed than the normal timing. Read data is fetched at the rising edge of CKIO, which is half a cycle faster than the normal timing. This timing allows the hold time of commands, addresses, write data, and read data to be extended. If SDRAM is operated at a high frequency with the SLOW bit set to 1, the setup time of commands, addresses, write data, and read data are not guaranteed. Take the operating frequency and timing design into consideration when making the SLOW bit setting.

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.

This pause interval should be provided by a power-on reset generating circuit or software. To perform SDRAM initialization correctly, the bus state controller registers 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, RASU, RASL, CASU, CASL, 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 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, 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 9.18. 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. Idle cycles, of which number is one or more, 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 there is data in a work area other than the specific area can be lost without severe repercussions. The low-power SDRAM supports the extension mode register (EMRS) in addition to the mode registers as the normal SDRAM. This LSI supports issuing of the EMRS command. 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 W1 to W0 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 9.20 lists a relationship between bus width, access size, and the number of bursts. Figure 9.35 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 9.36. 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 9.37 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 9.38 shows the access timing when a software wait is specified.

In addition, the bits SA[1:0] in CSnWCR (n = 5 and 6) assign the upper or lower 32 Mbytes of each area 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 or CS6BCR. Figure 9.41 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), tri-state buffers must be connected between the 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 areas 5 and 6 are 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 and CS6WCR. 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, CE1B, CE2B), 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 areas 5 and 6 to be specified independently, using CS5WCR and CS6WCR. In the PCMCIA interface, as in the normal space interface, a software wait or hardware wait using the WAIT pin can be inserted. Figure 9.43 shows the PCMCIA memory bus wait timing.

As shown in the example in figure 9.44, 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 and CS6WCR. 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 or 6 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 and CE2B signals are 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 or CE2. The basic waveforms for dynamic bus-size adjustment are shown in figure 9.46. 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.

Figures 9.48 to 9.51 show the burst MPX space access timings. Area 6 can be specified as the address/data multiplex I/O (MPX-I/O) interface using the TYPE2 to TYPE0 bits in CS6BCR. This MPX-I/O interface enables the LSI to be easily connected to an external memory controller chip that uses an address/data multiplexed 32-bit single bus. In this case, the address and the access size for the MPX-I/O interface are output to D25 to D0 and D31 to D29, respectively, in address cycles. For the access sizes of D31 to D29, see the description of CS6WCR for the burst MPX-I/O in section 9.4.3 (5), Burst MPX-I/O. Address pins A25 to A0 are used to output normal addresses. In the burst MPX-I/O interface, the bus size is fixed at 32 bits. The BSZ1 and BSZ0 bits in CS6BCR must be specified as 32 bits. In the burst MPX-I/O interface, a software wait and hardware wait using the WAIT pin can be inserted. In read cycles, a wait cycle is inserted automatically following the address output even if the software wait insertion is specified as 0. 64K x 16-bit SRAM This LSI CS6 CS BS BS FRAME FRAME RD/WR WE D31 I/O31 D0 I/O0 WAIT WAIT Figure 9.47 Burst MPX Device Connection Example Rev. 3.00 Sep. 28, 2009 Page 374 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) Tm1 Tmd1w Tmd1 CKIO FRAME D31 to D0 A D A25 to A0 CS6 RD/WR WAIT BS DACKn* Note: * The waveform for DACKn is when active low is specified.

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. If the bus width is 16 bits, the burst length must be specified as 8. If 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 and CE2B for PCMCIA. There are eight conditions that determine the number of idle cycles on the external bus as shown in table 9.21. The effects of these conditions are shown in figure 9.53. Rev. 3.00 Sep. 28, 2009 Page 380 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) Table 9.21 Conditions for Determining Number of Idle Cycles No. Condition Description Range Note [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 DMAC 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] 0 to 3 SDRAM-related These bits specify precharge completion and startup wait cycles bits in and idle cycles between commands CSnWCR for SDRAM access. This condition is effective only for SDRAM access and generates idle cycles after the access is completed [4] WM in CSnWCR Specify these bits in accordance with the specification of the target SDRAM. 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. Rev. 3.00 Sep. 28, 2009 Page 381 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) No. Condition Description [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. [6] Internal bus External bus access requests from 0 or idle cycles, etc. the CPU or DMAC and their results larger 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 BSC 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 clock ratio. Tables 9.22 and 9.23 show the relationship between the clock ratio and the minimum number of internal bus idle cycles. [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 Note One idle cycle is always generated after a read cycle with SDRAM or PCMCIA interface. To ensure the minimum pulse width 0 to 2.5 The number of idle cycles on the signal-multiplexed pins, idle depends on the target memory cycles may be inserted before types. See table 9.24. access after memory types are switched. For some memory types, idle cycles are inserted even when memory types are not switched.

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.

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 DMAC 6. Setting the BLOCK bit in CMNCR to 1 7. 16-byte to 128-byte transfer by the LCDC Moreover, by using DPRTY bit in CMNCR, whether the bus mastership request is received or not can be selected during DMAC burst transfer. 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. 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, RASU, RASL, CASU, CASL, CKE, DQMxx, WEn, RD, and RD/WR) are placed in Rev. 3.00 Sep. 28, 2009 Page 387 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) the high-impedance state at subsequent rising edges of CKIO. Bus request signals are sampled at the falling edge of CKIO. Note that CKE, RASU, RASL, CASU, and CASL 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 9.55 shows the bus arbitration timing. When it is necessary to refresh SDRAM while releasing the bus mastership, the bus mastership should be returned using the REFOUT signal. For details on the selection of REFOUT, see section 25, Pin Function Controller (PFC). The REFOUT signal is kept asserting at low level until the bus mastership is acquired. The BREQ signal is negated by asserting the REFOUT signal and the bus mastership is returned from the external device. If the bus mastership is not returned for a 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. Internal bus masters other than the CPU and bus state controller 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 cache bus is disabled. This gives rise to the following problems. On-chip bus masters such as DMAC 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 Rev. 3.00 Sep. 28, 2009 Page 389 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) 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. 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 (BSC) incorporates a one-stage write buffer, the BSC 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 BSC functions in the same way for an access by a bus master other than the CPU such as the DMAC. 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 write cycle will not be initiated until the previous write cycle is completed. Rev. 3.00 Sep. 28, 2009 Page 390 of 1650 REJ09B0313-0300 Section 9 Bus State Controller (BSC) Changing the registers in the BSC while the write buffer is operating may disrupt correct write access. Therefore, do not change the registers in the BSC immediately after a write access. If this change becomes necessary, do it after executing a dummy read of the write data. (3) On-Chip Peripheral Module Access To access an on-chip module register, two or more peripheral module clock (P) 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 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. 9.6 Usage Notes 9.6.1 Note when using both the bus arbitration function and the software standby mode When using both the bus arbitration function and the software standby mode, set the bus arbitration function disable (set the BLOCK bit in CMNCR to 1) before entering the software standby mode, and set the bus arbitration function enable (set the BLOCK bit in CMNCR to 0) after cancelling the software standby mode. If the LSI enter the software standby mode in the case that the BLOCK bit is set to 0, BACK pin outputs low for 1 bus clock (B) cycle after canceling the software standby mode even though BREQ input is high.

Eight SCIF sources, eight IIC3 sources, one A/D converter source, five MTU2 sources, two CMT sources, two USB sources, two FLCTL sources, two RCAN-TL1 sources, four SSI sources, four SSU sources * Selectable bus modes Cycle steal mode (normal mode and intermittent mode) Burst mode * Selectable channel priority levels: The channel priority levels are selectable between fixed mode and round-robin mode. * Interrupt request: An interrupt request can be sent to the CPU on completion of half- or fulldata transfer. Through the HE and HIE bits in CHCR, an interrupt is specified to be issued to the CPU when half of the initially specified DMA transfer is completed. Rev. 3.00 Sep. 28, 2009 Page 393 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) * External request detection: There are following four types of DREQ input detection. Low level detection High level detection Rising edge detection Falling edge detection * Transfer request acknowledge and transfer end signals: Active levels for DACK and TEND can be set independently. * Support of reload functions in DMA transfer information registers: DMA transfer using the same information as the current transfer can be repeated automatically without specifying the information again. Modifying the reload registers during DMA transfer enables next DMA transfer to be done using different transfer information. The reload function can be enabled or disabled independently in each channel or reload register.

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.

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.* 2 Even if the DE bit is set to 1 while the TEMASK bit is 0 and this bit is 1, transfer is not enabled. 0: During the DMA transfer or DMA transfer has been terminated [Clearing condition] * 2 Writing 0 after reading TE = 1* 1: DMA transfer ends by the specified count (DMATCR = 0) 0 DE 0 R/W DMA Enable Enables or disables the DMA transfer. 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 Notes: 1. Only 0 can be written to clear the flag after 1 is read.

If the flag is read at the same timing it is set to 1, the read data will be 0, but the internal state may be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be cleared to 0 because the internal state is the same as when writing 0 after reading 1.

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.

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.

If the DME bit and DE bit in CHCR are set to 1, DMA transfer is enabled. However, transfer is enabled only when the TE bit in CHCR of the transfer corresponding channel, the NMIF bit in DMAOR, and the AE bit are all cleared to 0. Clearing the DME bit to 0 can terminate the DMA transfer on all channels. 0: DMA transfer is disabled on all channels 1: DMA transfer is enabled on all channels Notes: 1. Only 0 can be written to clear the flag after 1 is read. 2. If the flag is read at the same timing it is set to 1, the read data will be 0, but the internal state may be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be cleared to 0 because the internal state is the same as when writing 0 after reading 1. For details, refer to section 10.5.5, Notes on Using Flag Bits. If the priority mode bits are modified after a DMA transfer, the channel priority is initialized. If fixed mode 2 is specified, the channel priority is specified as CH0 > CH4 > CH1 > CH5 > CH2 > CH6 > CH3 > CH7. If fixed mode 1 is specified, the channel priority is specified as CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7. If the round-robin mode is specified, the transfer end channel is reset. Table 10.3 show the priority change in each mode (modes 0 to 2) specified by the priority mode bits. In each priority mode, the channel priority to accept the next transfer request may change in up to three ways according to the transfer end channel. For example, when the transfer end channel is channel 1, the priority of the channel to accept the next transfer request is specified as CH2 > CH3 > CH0 >CH1 > CH4 > CH5 > CH6 > CH7. When the transfer end channel is any one of the channels 4 to 7, round-robin will not be applied and the priority level is not changed at the end of transfer in the channels 4 to 7.

Rev. 3.00 Sep. 28, 2009 Page 420 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) 10.4 Operation When there is a DMA transfer request, the DMAC 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. 10.4.1 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, the DMAC 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, the DMAC 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 the DMAC 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_7 and DMARS0 to DMARS3. (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 the DMAC to automatically generate a transfer request signal internally. When the DE bits in CHCR_0 to CHCR_7 and the DME bit in DMAOR are set to 1, the transfer begins so long as the TE bits in CHCR_0 to CHCR_7, and the AE and NMIF bits in DMAOR are 0. (2) External Request Mode In this mode a transfer is performed at the request signals (DREQ0 to DREQ3) of an external device. Choose one of the modes shown in table 10.5 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 10.5 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 External device with DACK External device with DACK External memory, memory-mapped external device Rev. 3.00 Sep. 28, 2009 Page 423 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) Choose to detect DREQ by either the edge or level of the signal input with the DL and DS bits in CHCR_0 to CHCR_3 as shown in table 10.6. 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 10.6 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 10.7 Selecting External Request Detection with DO Bit CHCR DO Bit External Request 0 Overrun 0 1 Overrun 1 Rev. 3.00 Sep. 28, 2009 Page 424 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) (3) On-Chip Peripheral Module Request In this mode, the transfer is performed in response to the DMA transfer request signal from an onchip peripheral module. Table 10.8 lists the DMA transfer request signals sent from on-chip peripheral modules to DMAC. 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 10.8.

Three modes (fixed mode 1, fixed mode 2, and round-robin mode) are selected using the PR1 and PR0 bits in DMAOR. (1) Fixed Mode In fixed modes, the priority levels among the channels remain fixed. There are two kinds of fixed modes as follows: Fixed mode 1: CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Fixed mode 2: CH0 > CH4 > CH1 > CH5 > CH2 > CH6 > CH3 > CH7 These are selected by the PR1 and PR0 bits in the DMA operation register (DMAOR). (2) Round-Robin Mode Each time one unit of word, byte, longword, or 16 bytes is transferred on one channel, the priority order is rotated. The channel on which the transfer was just finished is rotated to the lowest of the priority order among the four round-robin channels (channels 0 to 4). The priority of the channels other than the round-robin channels (channels 0 to 4) does not change even in round-robin mode. The round-robin mode operation is shown in figure 10.3. The priority in round-robin mode is CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 immediately after a reset. When the round-robin mode has been specified, do not concurrently specify cycle steal mode and burst mode as the bus modes of any two or more channels. Rev. 3.00 Sep. 28, 2009 Page 428 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) (1) When channel 0 transfers Initial priority order CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Priority order after transfer CH1 > CH2 > CH3 > CH0 > CH4 > CH5 > CH6 > CH7 Channel 0 is given the lowest priority among the round-robin channels. (2) When channel 1 transfers Initial priority order CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Priority order after transfer CH2 > CH3 > CH0 > CH1 > CH4 > CH5 > CH6 > CH7 Channel 1 is given the lowest priority among the round-robin channels. The priority of channel 0, which was higher than channel 1, is also shifted. (3) When channel 2 transfers Initial priority order CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Priority order after transfer CH3 > CH0 > CH1 > CH2 > CH4 > CH5 > CH6 > CH7 Post-transfer priority order when there is an immediate transfer request to channel 5 only Channel 2 is given the lowest priority among the round-robin channels. The priority of channels 0 and 1, which were higher than channel 2, is also shifted. If there is a transfer request only to channel 5 immediately after that, the priority does not change because channel 5 is not a round-robin channel. CH3 > CH0 > CH1 > CH2 > CH4 > CH5 > CH6 > CH7 (4) When channel 7 transfers Initial priority order CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Priority order after transfer CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Priority order does not change. Figure 10.3 Round-Robin Mode Rev. 3.00 Sep. 28, 2009 Page 429 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) Figure 10.4 shows how the priority order changes when channel 0 and channel 3 transfers are requested simultaneously and a channel 1 transfer is requested during the channel 0 transfer. The DMAC operates as follows: 1. Transfer requests are generated simultaneously to channels 0 and 3. 2. Channel 0 has a higher priority, so the channel 0 transfer begins first (channel 3 waits for transfer). 3. A channel 1 transfer request occurs during the channel 0 transfer (channels 1 and 3 are both waiting) 4. When the channel 0 transfer ends, channel 0 is given the lowest priority among the round-robin channels. 5. At this point, channel 1 has a higher priority than channel 3, so the channel 1 transfer begins (channel 3 waits for transfer). 6. When the channel 1 transfer ends, channel 1 is given the lowest priority among the round-robin channels. 7. The channel 3 transfer begins. 8. When the channel 3 transfer ends, channels 3 and 2 are lowered in priority so that channel 3 is given the lowest priority among the round-robin channels.

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. The DMAC supports the transfers shown in table 10.9.

The transfer source and destination can be located externally or internally. 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 the DMAC. In the transfer between external memories as shown in figure 10.5, data is read to the DMAC 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. DMAC SAR Data bus Address bus DAR Memory 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 DMAC. First bus cycle DMAC Memory Data bus DAR Address bus SAR Transfer source module Transfer destination module Data buffer The DAR value is an address and the value stored in the data buffer in the DMAC is written to the transfer destination module. Second bus cycle Figure 10.5 Data Flow of Dual Address Mode Auto request, external request, and on-chip peripheral module request are available for the transfer request. 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. Rev. 3.00 Sep. 28, 2009 Page 432 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) Figure 10.6 shows an example of DMA transfer timing in dual address mode.

In this mode, the DMAC 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 10.7, when the external device outputs data to the data bus, that data is written to the external memory in the same bus cycle. External address bus External data bus This LSI External memory DMAC External device with DACK DACK DREQ Data flow (from memory to device) Data flow (from device to memory) Figure 10.7 Data Flow in Single Address Mode Two kinds of transfer are possible in single address mode: (1) transfer between an external device with DACK and a memory-mapped external device, and (2) transfer between an external device with DACK and external memory. 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 10.9 shows an example of DMA transfer timing in cycle-steal normal mode. Transfer conditions shown in the figure are; Rev. 3.00 Sep. 28, 2009 Page 435 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) Dual address mode DREQ low level detection DREQ Bus mastership returned to CPU once Bus cycle CPU CPU CPU DMAC DMAC CPU Read/Write DMAC DMAC CPU Read/Write Figure 10.9 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, DMAC 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, DMAC obtains the bus mastership from other bus master after waiting for 16 or 64 cycles of B clock. DMAC 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 DMAC obtains again the bus mastership, DMA transfer may be postponed in case of entry updating due to cache miss. 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 10.10 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 DMAC DMAC Read/Write CPU CPU DMAC DMAC CPU Read/Write Figure 10.10 Example of DMA Transfer in Cycle-Steal Intermittent Mode (Dual Address, DREQ Low Level Detection) Rev. 3.00 Sep. 28, 2009 Page 436 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) (b) Burst Mode In burst mode, once the DMAC 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 DMAC 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 MTU2 and CMT as the transfer request source, the requesting module must be designated as the transfer source or the transfer destination. 2. 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, channels 0 to 3 are only available. 4. External requests, auto requests, and on-chip peripheral module requests are all available.

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 10.12. 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 10.18. Figures 10.13 to 10.17 show the cases where DACK and TEND are not divided in the DMA transfer.

Even though the value of DMATCR_n is rewritten by reload operation, half end flag is set based on the value set when transfer is started. Because of this, there may be errors where (a) the set timing of the half end flag is not correct, or (b) the half end flag can not be set, may be generated. When executing DMA transfer by reload function under the condition that different values are set to RDMATCR_n from DMATCR_n, do not use half end flag or half end interrupt. 10.5.2 Timing of DACK and TEND Outputs When the external memory is the MPX-I/O or burst MPX-I/O, the DACK output is asserted with the timing of the data cycle. For details, see the respective figures in section 9.5.5, MPX-I/O Interface, or section 9.5.10, Burst MPX-I/O Interface. When the memory is other than the MPX-I/O or burst 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.

If using other than the above four ways, there is a possibility that DACKn pin and TENDn pin show wrong transfer channel and since then until power-on reset DMA transfer is unavailable. Additionally if this state occurs in burst-mode, CPU becomes unable to fetch instructions, then system becomes suspended.

Rev. 3.00 Sep. 28, 2009 Page 446 of 1650 REJ09B0313-0300 Section 10 Direct Memory Access Controller (DMAC) 10.5.5 Notes on Using Flag Bits The notes on using the following flag bits are described here. * DMA channel control register (CHCR) HE (Half-End) and TE (Transfer End Flag) bits * DMA operation register (DMAOR) AE (Address Error Flag) and NMIF (NMI Flag) bits If a flag is read at the same timing it is set to 1, the read data will be 0, but the internal state may be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be cleared to 0 because the internal state is the same as when writing 0 after reading 1. In the case of using a flag, to prevent from unintentionally clearing the flag bit to 0, perform read/write as follows: (a) In the case of intended bit clear, write 0 to the flag bit after reading it as 1. (b) In other cases, write 1 to the flag bit. If a flag is not used, just writing 0 to the flag bit does not generate errors (in the case of intended bit clear, write 0 to the flag bit after reading it as 1).

When the input clock is counted using both edges, the input clock period is halved (e.g. P/4 both edges = P/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 P/4 or slower. When P/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.

The MTU2 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 MTU2 external pins set function using the pin function controller (PFC). (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 11.4 shows an example of the count operation setting procedure. [1] Select the counter clock with bits TPSC2 to TPSC0 in TCR. At the same time, select the input clock edge with bits CKEG1 and CKEG0 in TCR.

When the relevant bit in TSTR is set to 1 the corresponding TCNT counter starts up-count 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, the MTU2 requests an interrupt. After overflow, TCNT starts counting up again from H'0000. Figure 11.5 illustrates free-running counter operation. TCNT value H'FFFF H'0000 Time CST bit TCFV Figure 11.5 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, the MTU2 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, P/1 should not be selected as the counter input clock used for input capture input. Input capture will not be generated if P/1 is selected. (a) Example of Input Capture Operation Setting Procedure Figure 11.10 shows an example of the input capture operation setting procedure.

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.

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 11.4.5, 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 11.41 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 11.4.5, PWM Modes.

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 11.19 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.

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 11.42 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.

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 synchronization 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 11.44.

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 11.45 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.

[3] When performing brushless DC motor control, set bit BDC in the timer gate control register (TGCR) and set the feedback signal input source and output chopping or gate signal direct output.

In this case, synchronize the channel generating the synchronous clear with channels 3 and 4 using the timer synchro register (TSYR). [6] Set the output PWM duty in the duty registers (TGRB_3, TGRA_4, TGRB_4) and buffer registers (TGRD_3, TGRC_4, TGRD_4). Set the same initial value in each corresponding TGR. [7] This setting is necessary only when no dead time should be generated. Make appropriate settings in the timer dead time enable register (TDER) so that no dead time is generated. [8] Set the dead time in the dead time register (TDDR), 1/2 the carrier cycle in the carrier cycle data register (TCDR) and carrier cycle buffer register (TCBR), and 1/2 the carrier cycle plus the dead time in TGRA_3 and TGRC_3. When no dead time generation is selected, set 1 in TDDR and 1/2 the carrier cycle + 1 in TGRA_3 and TGRC_3. [9] Select enabling/disabling of toggle output synchronized with the PWM cycle using bit PSYE in the timer output control register 1 (TOCR1), and set the PWM output level with bits OLSP and OLSN. When specifying the PWM output level by using TOLBR as a buffer for TOCR_2, see figure 11.3. [10] Select complementary PWM mode in timer mode register 3 (TMDR_3). Do not set in TMDR_4.

Figure 11.39 illustrates counter operation in complementary PWM mode, and figure 11.40 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 11.40 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 11.40 shows an example in which the mode is selected in which the change is made in the trough. In the tb interval (tb1 in figure 11.40) in which data transfer to the temporary register is not performed, the temporary register has the same function as the compare register, and is compared Rev. 3.00 Sep. 28, 2009 Page 560 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) with the counter. 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. Table 11.54 Registers and Counters Requiring Initialization Register/Counter Set Value TGRC_3 1/2 PWM carrier cycle + dead time Td (1/2 PWM carrier cycle + 1 when dead time generation is disabled by TDER) TDDR Dead time Td (1 when dead time generation is disabled by TDER) TCBR 1/2 PWM carrier cycle TGRD_3, TGRC_4, TGRD_4 Initial PWM duty value for each phase TCNT_4 H'0000 Note: The TGRC_3 set value must be the sum of 1/2 the PWM carrier cycle set in TCBR and dead time Td set in TDDR. When dead time generation is disabled by TDER, TGRC_3 must be set to 1/2 the PWM carrier cycle + 1. Rev. 3.00 Sep. 28, 2009 Page 563 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) (d) PWM Output Level Setting In complementary PWM mode, the PWM pulse output level is set with bits OLSN and OLSP in timer output control register 1 (TOCR1) or bits OLS1P to OLS3P and OLS1N to OLS3N in timer output control register 2 (TOCR2). 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 11.41 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 11.42 illustrates the operation when the PWM cycle is updated at the crest. See the following section, Register Data Updating, for the method of updating the data in each buffer register. Counter value TGRC_3 update TGRA_3 update TCNT_3 TGRA_3 TCNT_4 Time Figure 11.42 Example of PWM Cycle Updating Rev. 3.00 Sep. 28, 2009 Page 566 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) (h) Register Data Updating In complementary PWM mode, the buffer register is used to update the data in a compare 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 11.43 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 11.44 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 11.45.

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 data register. While TCNTS is counting, data 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 11.46 to 11.48 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 11.46. 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 11.47, 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 11.48, 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 11.49 to 11.53 show output examples. 100% duty output is performed when the data 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 data 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 11.54. 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.

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 11.56. 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 11.56) immediately after the counters start operation, initial value output is not suppressed.

Figures 11.63 to 11.66 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 PFC). 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. Rev. 3.00 Sep. 28, 2009 Page 587 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) (3) Interrupt Skipping in Complementary PWM Mode Interrupts TGIA_3 (at the crest) and TCIV_4 (at the trough) in channels 3 and 4 can be skipped up to seven times by making settings in the timer interrupt skipping set register (TITCR). 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 11.4.9, 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 11.67 shows an example of the interrupt skipping operation setting procedure. Figure 11.68 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. Interrupt skipping Clear interrupt skipping counter [1] Set skipping count and enable interrupt skipping [2] <Interrupt skipping> [2] Specify the interrupt skipping count within the range from 0 to 7 times in bits 3ACOR2 to 3ACOR0 and 4VCOR2 to 4VCOR0 in TITCR, and enable interrupt skipping through bits T3AEN and T4VEN. 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 11.70 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 11.71 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 outside the buffer transfer-enabled period. Due to the buffer register rewrite timing after an interrupt, the timing of transfers from a buffer register to a temporary register differs from the timing of transfers from a temporary register to a 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 11.72 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 making settings in the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in TADCR. * Example of Procedure for Specifying A/D Converter Start Request Delaying Function Figure 11.73 shows an example of procedure for specifying the A/D converter start request delaying function.

The timing for capturing in TGR can be selected by TIOR. Figure 11.77 shows an example in which TCNT is used as a free-running counter without being cleared, and the TCNT value is captured in TGR at the specified timing (either crest or trough, or both crest and trough).

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 6, Interrupt Controller (INTC). Table 11.55 lists the MTU2 interrupt sources.

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. The MTU2 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. The MTU2 has five overflow interrupts, one for each channel. (3) 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. The MTU2 has two underflow interrupts, one each for channels 1 and 2. Rev. 3.00 Sep. 28, 2009 Page 600 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) 11.5.2 DMAC Activation The DMAC can be activated by the TGRA input capture/compare match interrupt in each channel. For details, see section 10, Direct Memory Access Controller (DMAC). In the MTU2, a total of five TGRA input capture/compare match interrupts can be used as DMAC activation sources, one each for channels 0 to 4. 11.5.3 A/D Converter Activation The A/D converter can be activated by one of the following three methods in the MTU2. Table 11.56 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 the MTU2 is selected as the trigger in the A/D converter, A/D conversion will start. (2) 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 the MTU2 is selected as the trigger in the A/D converter, A/D conversion will start. Rev. 3.00 Sep. 28, 2009 Page 601 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) (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, and DT4BE bit in the A/D converter start request control register (TADCR) is set to 1. For details, refer to section 11.4.9, A/D Converter Start Request Delaying Function. A/D conversion will start if A/D converter start signal TRG4AN from the MTU2 is selected as the trigger in the A/D converter when TRG4AN is generated or if TRG4BN from the MTU2 is selected as the trigger in the A/D converter when TRG4BN is generated.

When a compare match signal is generated, the output value set in TIOR is output at the output compare output pin (TIOC pin). After a match between TCNT and TGR, the compare match signal is not generated until the TCNT input clock is generated.

The initial setting is for MTU2 operation to be halted. Register access is enabled by clearing module standby mode. For details, refer to section 28, Power-Down Modes. 11.7.2 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. The MTU2 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 11.107. 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 11.109 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 11.110 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. Rev. 3.00 Sep. 28, 2009 Page 628 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) 11.7.20 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. 11.7.21 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 DMAC activation source. Interrupts should therefore be disabled before entering module standby mode. 11.7.22 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. Rev. 3.00 Sep. 28, 2009 Page 629 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) 11.8 MTU2 Output Pin Initialization 11.8.1 Operating Modes The MTU2 has the following six operating modes. 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 MTU2 output pin initialization method for each of these modes is described in this section. 11.8.2 Reset Start Operation The MTU2 output pins (TIOC*) are initialized low by a reset and in standby mode. Since MTU2 pin function selection is performed by the pin function controller (PFC), when the PFC is set, the MTU2 pin states at that point are output to the ports. When MTU2 output is selected by the PFC immediately after a reset, the MTU2 output initial level, low, is output directly at the port. When the active level is low, the system will operate at this point, and therefore the PFC setting should be made after initialization of the MTU2 output pins is completed. Note: Channel number and port notation are substituted for *. Rev. 3.00 Sep. 28, 2009 Page 630 of 1650 REJ09B0313-0300 Section 11 Multi-Function Timer Pulse Unit 2 (MTU2) 11.8.3 Operation in Case of Re-Setting Due to Error During Operation, etc. If an error occurs during MTU2 operation, MTU2 output should be cut by the system. Cutoff is performed by switching the pin output to port output with the PFC 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. The MTU2 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 11.57.

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 11.57. The active level is assumed to be low.

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. Figure 12.2 shows the operation of the compare match counter.

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 6, Interrupt Controller (INTC). Clear the CMF bit to 0 by the user exception handling routine. If this operation is not carried out, another interrupt will be generated. The direct memory access controller (DMAC) can be set to 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 DMAC 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 DMAC. 12.4.2 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 12.4 shows the timing of CMF bit setting.

The WDT can simultaneously generate an internal reset signal for the entire LSI. The WDT is a single channel timer that counts up the clock oscillation settling period when the system leaves software standby mode or the temporary standby periods that occur when the clock frequency is changed. It can also be used as a general watchdog timer or interval timer. 13.1 Features * Can be used to ensure the clock oscillation settling time The WDT is used in leaving software standby mode or the temporary standby periods that occur when the clock frequency is changed. * 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. It is possible to select whether to reset the LSI internally when this happens. Either the power-on reset or manual reset signal can be selected as the internal reset type. * Interrupt generation in interval timer mode An interval timer interrupt is generated when the counter overflows. * Choice of eight counter input clocks Eight clocks (P x 1 to P x 1/16384) that are obtained by dividing the peripheral clock can be selected.

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 13.3.4, 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 13.2. 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 Write data 8 7 H'A5 Figure 13.2 Writing to WTCNT and WTCSR Rev. 3.00 Sep. 28, 2009 Page 682 of 1650 REJ09B0313-0300 0 7 H'5A Address: H'FFFE0002 0 Write data Section 13 Watchdog Timer (WDT) (2) 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 13.3. 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. Writing 0 to the WOVF bit 15 Writing to the RSTE and RSTS bits Address: H'FFFE0004 8 7 H'A5 Address: H'FFFE0004 15 0 H'00 8 7 H'5A 0 Write data Figure 13.3 Writing to WRCSR (3) Reading from WTCNT, WTCSR, and WRCSR WTCNT, WTCSR, and WRCSR are read in a method similar to other registers. 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. Rev. 3.00 Sep. 28, 2009 Page 683 of 1650 REJ09B0313-0300 Section 13 Watchdog Timer (WDT) 13.4 WDT Usage 13.4.1 Canceling Software Standby Mode The WDT can be used to cancel software standby mode with an interrupt such as an NMI interrupt. The procedure is described below. (The WDT 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 bit of the standby control register (STBCR: see section 28, PowerDown Modes) to 1, the execution of a SLEEP instruction puts the system in software standby mode and clock operation then stops. 4. The WDT starts counting by detecting the edge change of the NMI signal. 5. When the WDT count overflows, the CPG starts supplying the clock and this LSI resumes operation. The WOVF flag in WRCSR is not set when this happens. 13.4.2 Changing the Frequency To change the frequency used by the PLL, use the WDT. When changing the frequency only by switching the divider, do not use the WDT. 1. Before changing the frequency, 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. However, the WDT counts up using the clock after the setting. 3. When the frequency control register (FRQCR) is written to, this LSI stops temporarily. The WDT starts counting. 4. When the WDT count overflows, the CPG resumes supplying the clock and this LSI resumes operation. The WOVF flag in WRCSR is not set when this happens. Rev. 3.00 Sep. 28, 2009 Page 684 of 1650 REJ09B0313-0300 Section 13 Watchdog Timer (WDT) 5. The counter stops at the value of H'00. 6. Before changing WTCNT after execution of the frequency change instruction, always confirm that the value of WTCNT is H'00 by reading from WTCNT. 13.4.3 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, the WDT sets the WOVF flag in WRCSR to 1, and the WDTOVF signal is output externally (figure 13.4). The WDTOVF signal can be used to reset the system. The WDTOVF signal is output for 64 x P 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 P clock cycles. 6. When a WDT overflow reset 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, the WDT sets the IOVF bit in WTCSR to 1 and an interval timer interrupt request is sent to the INTC. The counter then resumes counting.

The shortest such time period is thus one cycle of the peripheral clock, P, 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. 13.5.2 Prohibition against Setting H'FF to WTCNT When the value in WTCNT reaches H'FF, the WDT assumes that an overflow has occurred. Accordingly, when H'FF is set in WTCNT, an interval timer interrupt or WDT reset will occur immediately, regardless of the current clock selection by the CKS[2:0] bits. 13.5.3 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.

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 clear, 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 14.4 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, RYRCNT The RTC count must be stopped before writing to any of the above registers. 14.5.2 Use of Real-time Clock (RTC) Periodic Interrupts The method of using the periodic interrupt function is shown in figure 14.5. 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 14.5 Using Periodic Interrupt Function 14.5.3 Transition to Standby Mode after Setting Register When a transition to standby mode is made after registers in the RTC are set, sometimes counting is not performed correctly.

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.

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. 15.1 Features * Asynchronous serial communication: Serial data communication is performed by start-stop in character units. The SCIF 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. The SCIF 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 the SCIF 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) Rev. 3.00 Sep. 28, 2009 Page 721 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) * Four types of interrupts: Transmit-FIFO-data-empty interrupt, break interrupt, receive-FIFOdata-full interrupt, and receive-error interrupts are requested independently. * When the SCIF 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 3). * 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.

The SCIF completes the reception of one byte of serial data by moving the received data from the receive shift register (SCRSR) into 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.

The SCIF loads transmit data from the transmit FIFO data register (SCFTDR) into SCTSR, then transmits the data serially from the TxD pin, LSB (bit 0) first. After transmitting one data byte, the SCIF automatically loads the next transmit data from SCFTDR into SCTSR and starts transmitting again.

When the SCIF detects that the transmit shift register (SCTSR) is empty, it moves transmit data written in the SCFTDR into SCTSR and starts serial transmission. 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.

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. 0: Even parity* 1: Odd parity* 1 2 Notes: 1.

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.

The SCIF 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 3 has RTS and CTS signals to be used as modem control signals. The transmission format is selected in the serial mode register (SCSMR), as shown in table 15.9. The SCIF clock source is selected by the combination of the CKE1 and CKE0 bits in the serial control register (SCSCR), as shown in table 15.10. (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 SCIF clock source. When an internal clock is selected, the SCIF 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.) Rev. 3.00 Sep. 28, 2009 Page 763 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) (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 SCIF clock source. When an internal clock is selected, the SCIF 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, the SCIF 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 of the SCIF 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 15.2 shows the general format of asynchronous serial communication. In asynchronous serial communication, the communication line is normally held in the mark (high) state. The SCIF 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, the SCIF synchronizes at the falling edge of the start bit. The SCIF 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 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 15.10, SCSMR and SCSCR Settings and SCIF 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 the SCIF 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 * SCIF Initialization (Asynchronous Mode) Before transmitting or receiving, clear the TE and RE bits to 0 in the serial control register (SCSCR), then initialize the SCIF 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. SCIF operation becomes unreliable if the clock is stopped. Rev. 3.00 Sep. 28, 2009 Page 768 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) Figure 15.3 shows a sample flowchart for initializing the SCIF. 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 PFC setting for 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 PFC for 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 the SCIF for transmission. Start of transmission 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 No Yes Break output? No Yes Clear SPB2DT to 0 and set SPB2IO to 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. [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? [1] SCIF 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). [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 15.4 Sample Flowchart for Transmitting Serial Data Rev. 3.00 Sep. 28, 2009 Page 770 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) In serial transmission, the SCIF operates as described below. 1. When data is written into the transmit FIFO data register (SCFTDR), the SCIF transfers the data from SCFTDR to the transmit shift register (SCTSR) and starts transmitting. 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 SCIF checks the SCFTDR transmit data 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 in channel 3, 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 15.6 shows an example of the operation when modem control is used.

[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] 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] SCIF 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? Yes 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 SCIF monitors the transmission line, and if a 0 start bit is detected, performs internal synchronization and starts reception. 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, the SCIF carries out the following checks. A. Stop bit check: The SCIF checks whether the stop bit is 1. If there are two stop bits, only the first is checked. B. The SCIF checks whether receive data can be transferred from the receive shift register (SCRSR) to SCFRDR. C. Overrun check: The SCIF checks that the ORER flag is 0, indicating that the overrun error has not occurred. D. Break check: The SCIF 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 SCIF transmitter and receiver 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 15.11 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, the SCIF receives data by synchronizing with the rising edge of the serial clock. Rev. 3.00 Sep. 28, 2009 Page 777 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) (1) Transmit/Receive Formats The data length is fixed at eight bits. 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 SCIF transmit/receive clock. When the SCIF 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 the SCIF is not transmitting or receiving, 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 * SCIF 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 the SCIF. 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.

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, the SCIF outputs eight synchronous clock pulses. If an external clock source is selected, the SCIF outputs data 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 SCIF checks the SCFTDR transmit data 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 15.14 shows an example of SCIF transmit operation.

The SCIF synchronizes with serial clock input or output and starts the reception. 2. Receive data is shifted into SCRSR in order from the LSB to the MSB. After receiving the data, the SCIF checks the receive data can be loaded from SCRSR into SCFRDR or not. If this check is passed, the RDF flag is set to 1 and the SCIF stores the received data 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, the SCIF requests a receive-data-full interrupt (RXI). 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, the SCIF requests a break interrupt (BRI).

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 15.18 Sample Flowchart for Transmitting/Receiving Serial Data Rev. 3.00 Sep. 28, 2009 Page 784 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) 15.5 SCIF Interrupts The SCIF has four interrupt sources: transmit-FIFO-data-empty (TXI), receive-error (ERI), receive FIFO data full (RXI), and break (BRI). Table 15.12 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 DMAC 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 DMAC 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, the SCIF requests an ERI or 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 15.12 SCIF Interrupt Sources Interrupt Source Description DMAC Activation Priority on Reset Release High 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) Possible Low Rev. 3.00 Sep. 28, 2009 Page 785 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) 15.6 Usage Notes Note the following when using the SCIF. 15.6.1 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). 15.6.2 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). Rev. 3.00 Sep. 28, 2009 Page 786 of 1650 REJ09B0313-0300 Section 15 Serial Communication Interface with FIFO (SCIF) 15.6.3 Restriction on DMAC Usage When the DMAC 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. 15.6.4 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 SCIF receiver continues to operate. 15.6.5 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. 15.6.6 Receive Data Sampling Timing and Receive Margin (Asynchronous Mode) The SCIF operates on a base clock with a frequency 16 or 8 times the bit rate. In reception, the SCIF synchronizes internally with the fall of the start bit, which it samples on the base clock. Receive data is latched at the rising edge of the eighth or fourth base clock pulse. When the SCIF operates on a base clock with a frequency 16 times the bit rate, the receive data is sampled at the timing shown in figure 15.19.

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%.

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 15.6.6, 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).

In SSU mode, when clearing RDRF in SSSR while reading receive data (reading SSRDR) when a slave device is in the receive operation state, or clearing TDRE in SSSR while writing transmit data (writing to SSTDR) when a slave device is in the transmit operation state, an incomplete error occurs at the end of the frame, even if clearing does not complete by the beginning of the next frame.

When 8-bit data length is selected by bits DATS1 and DATS0 in SSCRL, SSTDR0 is valid. When 16-bit data length is selected, SSTDR0 and SSTDR1 are valid. When 32-bit data length is selected, SSTDR0 to SSTDR3 are valid. The SSTDR that has not been enabled must not be accessed. When the SSU detects that SSTRSR is empty, it transfers the transmit data written in SSTDR to SSTRSR and starts serial transmission. If the next transmit data has already been written to SSTDR during serial transmission, the SSU performs consecutive serial transmission. Although SSTDR can always be read from or written to by the CPU and DMAC, to achieve reliable serial transmission, write transmit data to SSTDR after confirming that the TDRE bit in SSSR is set to 1.

When 32-bit data length is selected, SSRDR0 to SSRDR3 are valid. The SSRDR that has not been enabled must not be accessed. When the SSU has received 1-byte data, it transfers the received serial data from SSTRSR to SSRDR where it is stored. After this, SSTRSR is ready for reception. Since SSTRSR and SSRDR function as a double buffer in this way, consecutive receive operations can be performed. Read SSRDR after confirming that the RDRF bit in SSSR is set to 1. SSRDR is a read-only register, therefore, cannot be written to by the CPU.

When data is transferred from SSTDR to SSTRSR, bit 0 of transmit data is bit 0 in the SSTDR contents (MLS = 0: LSB first communication) and is bit 7 in the SSTDR contents (MLS = 1: MSB first communication). The SSU transfers data from the LSB (bit 0) in SSTRSR to the SSO pin to perform serial data transmission. In reception, the SSU sets serial data that has been input via the SSI pin in SSTRSR from the LSB (bit 0). When 1-byte data has been received, the SSTRSR contents are automatically transferred to SSRDR. SSTRSR cannot be directly accessed by the CPU.

Before using this module, enable the SSCK pin function in the PFC. When the MSS bit in SSCRH is 1, an internal clock is selected and the SSCK pin is used as an output pin. When transfer is started, the clock with the transfer rate set by bits CKS2 to CKS0 in SSMR is output from the SSCK pin. When MSS = 0, an external clock is selected and the SSCK pin is used as an input pin. 16.4.2 Relationship of Clock Phase, Polarity, and Data The relationship of clock phase, polarity, and transfer data depends on the combination of the CPOS and CPHS bits in SSMR when the value of the SSUMS bit in SSCRL is 0. Figure 16.2 shows the relationship. When SSUMS = 1, the CPHS setting is invalid although the CPOS setting is valid. When SSUMS = 1, the transmit data change timing and receive data fetch timing are the same as that shown as "(1) When CPHS = 0" in figure 16.2. Setting the MLS bit in SSMR selects either MSB first or LSB first communication. When MLS = 0, data is transferred from the LSB to the MSB. When MLS = 1, data is transferred from the MSB to the LSB.

Figure 16.3 shows the relationship. The SSU transmits serial data from the SSO pin and receives serial data from the SSI pin when operating with BIDE = 0 and MSS = 1 (standard, master mode) (see figure 16.3 (1)). The SSU transmits serial data from the SSI pin and receives serial data from the SSO pin when operating with BIDE = 0 and MSS = 0 (standard, slave mode) (see figure 16.3 (2)). The SSU transmits and receives serial data from the SSO pin regardless of master or slave mode when operating with BIDE = 1 (bidirectional mode) (see figures 16.3 (3) and (4)). However, even if both the TE and RE bits are set to 1, transmission and reception are not performed simultaneously. Either the TE or RE bit must be selected. The SSU transmits serial data from the SSO pin and receives serial data from the SSI pin when operating with SSUMS = 1. The SSCK pin outputs the internal clock when MSS = 1 and function as an input pin when MSS = 0 (see figures 16.3 (5) and (6)).

In addition, the SSU supports bidirectional mode in which a single pin functions as data input and data output lines. (1) Initial Settings in SSU Mode Figure 16.4 shows an example of the initial settings in SSU mode. Before data transfer, clear both the TE and RE bits in SSER to 0 to set the initial values. Note: Before changing operating modes and communications formats, clear both the TE and RE bits to 0. Although clearing the TE bit to 0 sets the TDRE bit to 1, clearing the RE bit to 0 does not change the values of the RDRF and ORER bits and SSRDR. Those bits retain the previous values.

When transmitting data, the SSU operates as shown below. In master mode, the SSU outputs a transfer clock and data. In slave mode, when a low level signal is input to the SCS pin and a transfer clock is input to the SSCK pin, the SSU outputs data in synchronization with the transfer clock. Writing transmit data to SSTDR after the TE bit is set to 1 clears the TDRE bit in SSSR to 0, and the SSTDR contents are transferred to SSTRSR. After that, the SSU sets the TDRE bit to 1 and starts transmission. At this time, if the TIE bit in SSER is set to 1, a transmit-data-empty SSTXI interrupt is generated. When 1-frame data has been transferred with TDRE = 0, the SSTDR contents are transferred to SSTRSR to start the next frame transmission. When the 8th bit of transmit data has been transferred with TDRE = 1, the TEND bit in SSSR is set to 1 and the state is retained. At this time, if the TEIE bit is set to 1, a transmit-end SSTXI interrupt is generated. After transmission, the output level of the SSCK pin is fixed high when CPOS = 0 and low when CPOS = 1. While the ORER bit in SSSR is set to 1, transmission is not performed. Check that the ORER bit is cleared to 0 before transmission.

When receiving data, the SSU operates as shown below. After setting the RE bit to 1 and dummy-reading SSRDR, the SSU starts data reception. In master mode, the SSU outputs a transfer clock and receives data. In slave mode, when a low level signal is input to the SCS pin and a transfer clock is input to the SSCK pin, the SSU receives data in synchronization with the transfer clock. When 1-frame data has been received, the RDRF bit in SSSR is set to 1 and the receive data is stored in SSRDR. At this time, if the RIE bit in SSER is set to 1, an SSRXI interrupt is generated. The RDRF bit is automatically cleared to 0 by reading SSRDR. During continuous slave reception in SSU mode, read the SS receive data register (SSRDR) before the next reception operation starts (before the externally connected master device starts the next transmission). When the next reception operation starts after the receive data full (RDRF) bit in the SS status register (SSSR) is set to 1 and before SSRDR is read, and SSRDR is read before reception of one frame completes, the conflict/incomplete error (CE) bit in SSSR is set to 1 after the reception operation ends. In addition, when the next reception operation starts after RDRF is set to 1 and before SSRDR is read, and SSRDR is not read before reception of one frame completes, the receive data is discarded, even though neither the CE bit nor the overrun error (ORER) bit in SSSR is set to 1.

The data transmission/reception is performed combining the data transmission and data reception as mentioned above. The data transmission/reception is started by writing transmit data to SSTDR with TE = RE = 1. When the RDRF bit is set to 1, at the 8th rising edge of the transfer clock the ORER bit in SSSR is set to 1, an overrun error (SSERI) is generated, and both transmission and reception are stopped. Transmission and reception are not possible while the ORER bit is set to 1. To resume transmission and reception, clear the ORER bit to 0. Before switching transmission mode (TE = 1) or reception mode (RE = 1) to transmission/reception mode (TE = RE = 1), clear the TE and RE bits to 0. When starting the transfer, confirm that the TEND, RDRF, and ORER bits are cleared to 0 before setting the TE or RE bit to 1.

A conflict error detection period is from setting the MSS bit in SSCRH to 1 to starting serial transfer and after transfer ends. When a low level signal is input to the SCS pin within the period, a conflict error occurs. At this time, the CE bit in SSSR is set to 1 and the MSS bit is cleared to 0.

(1) Initial Settings in Clock Synchronous Communication Mode Figure 16.12 shows an example of the initial settings in clock synchronous communication mode. Before data transfer, clear both the TE and RE bits in SSER to 0 to set the initial values. Note: Before changing operating modes and communications formats, clear both the TE and RE bits to 0. Although clearing the TE bit to 0 sets the TDRE bit to 1, clearing the RE bit to 0 does not change the values of the RDRF and ORER bits and SSRDR. Those bits retain the previous values. Start setting initial values [1] [2] Clear the TE and RE bits in SSER to 0 [1] Make appropriate settings in the PFC for the external pins to be used.

When transmitting data in clock synchronous communication mode, the SSU operates as shown below. In master mode, the SSU outputs a transfer clock and data. In slave mode, when a transfer clock is input to the SSCK pin, the SSU outputs data in synchronization with the transfer clock. Writing transmit data to SSTDR after the TE bit is set to 1 clears the TDRE bit in SSSR to 0, and the SSTDR contents are transferred to SSTRSR. After that, the SSU sets the TDRE bit to 1 and starts transmission. At this time, if the TIE bit in SSER is set to 1, a transmit-data-empty SSTXI interrupt is generated. When 1-frame data has been transferred with TDRE = 0, the SSTDR contents are transferred to SSTRSR to start the next frame transmission. When the 8th bit of transmit data has been transferred with TDRE = 1, the TEND bit in SSSR is set to 1 and the state is retained. At this time, if the TEIE bit in SSER is set to 1, a transmit-end SSTXI interrupt is generated. While the ORER bit in SSSR is set to 1, transmission is not performed.

When receiving data, the SSU operates as shown below. After setting the RE bit in SSER to 1, the SSU starts data reception. In master mode, the SSU outputs a transfer clock and receives data. In slave mode, when a transfer clock is input to the SSCK pin, the SSU receives data in synchronization with the transfer clock. When 1-frame data has been received, the RDRF bit in SSSR is set to 1 and the receive data is stored in SSRDR. At this time, if the RIE bit is set to 1, an SSRXI interrupt is generated. The RDRF bit is automatically cleared to 0 by reading SSRDR. When the RDRF bit has been set to 1 at the 8th rising edge of the transfer clock, the ORER bit in SSSR is set to 1. This indicates that an overrun error (SSERI) has occurred. At this time, data reception is stopped. While the ORER bit in SSSR is set to 1, reception is not performed.

Of these interrupt sources, a receive data register full, and a transmit data register empty can activate the DMAC for data transfer. Since both an overrun error and a conflict error interrupts are allocated to the SSERI vector address, and both a transmit data register empty and a transmit end interrupts are allocated to the SSTXI vector address, the interrupt source should be decided by their flags. Table 16.8 lists the interrupt sources. When an interrupt condition shown in table 16.8 is satisfied, an interrupt is requested. Clear the interrupt source by CPU or DMAC data transfer.

The initial setting is for SSU operation to be halted. Access to registers is enabled by clearing module standby mode. For details, refer to section 28, Power-Down Modes. 16.6.2 Note on Continuous Transmission/Reception in SSU Slave Mode During continuous transmission or reception in SSU slave mode, negate (drive high level) the SCS pin once per frame. Correct transmission and reception are not possible if the SCS pin is asserted (low level) for more than one frame. 16.6.3 Note in the Master Transmission Operation or the Master Transmission/Reception Operation of SSU Mode In the master transmission operation or the master transmission/reception operation of SSU mode, please operate one of the following three ways. (1) Write the next transmission data to the SSTDR after the TDRE bit of the SSSR is set to 1 and before the transmission of one bit before the last bit starts. (2) Write the next transmission data to the SSTDR after the TEND bit of the SSSR is set to 1. (3) Set the SSCR2 as "TENDSTS = 0" or "TENDSTS = 1 and SCSATS = 1".

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. 17.1 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 (DMAC) 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 (DMAC) can be activated by a transmit-data-empty request or receive-data-full request to transfer data.

For master transmit mode operation timing, refer to figures 17.5 and 17.6. 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 17.7 and 17.8. 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.

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.

For slave receive mode operation timing, refer to figures 17.11 and 17.12. The reception procedure and operations in slave receive 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 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 change of the acknowledge before reading ICDRR, to be returned to the master device, is reflected to the next transmit frame. 4. The last byte data is read by reading ICDRR.

When the MST bit in ICCR1 is 1, the transfer clock output from SCL is selected. When MST is 0, the external clock input is selected. (1) Data Transfer Format Figure 17.13 shows the clocked synchronous serial transfer format. 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 17.14. 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 17.15. 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 17.16 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 17.17 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 17.4 shows the contents of each interrupt request. Table 17.4 Interrupt Requests Interrupt Request Abbreviation Interrupt Condition I2C Bus Format Clocked Synchronous Serial Format Transmit data Empty TXI (TDRE = 1) * (TIE = 1) Transmit end 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) Arbitration lost/ overrun error When the interrupt condition described in table 17.4 is 1, the CPU executes an interrupt exception handling. Note that a TXI or RXI interrupt can activate the DMAC if the setting for DMAC 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. 17.7.3 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 is 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. Rev. 3.00 Sep. 28, 2009 Page 873 of 1650 REJ09B0313-0300 Section 17 I2C Bus Interface 3 (IIC3) 17.7.4 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. 17.7.5 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 Rev. 3.00 Sep. 28, 2009 Page 874 of 1650 REJ09B0313-0300 Section 18 Serial Sound Interface (SSI) Section 18 Serial Sound Interface (SSI) The serial sound interface (SSI) is a module designed to send or receive audio data interface with various devices offering Philips format compatibility.

If UIRQ = 1 and UIEN = 1, an interrupt occurs. * TRMD = 0 (Receive mode) If UIRQ = 1, SSIRDR was read before there was new unread data indicated by the DMRQ or DIRQ bit. This can lead to the same received sample being stored twice by the host leading to potential corruption of multi-channel data. * TRMD = 1 (Transmit mode) If UIRQ = 1, SSITDR did not have data written to it before it was required for transmission. This will lead to the same sample being transmitted once more and a potential corruption of multi-channel data. This is more serious error than a receive mode underflow as the output SSI data results in error. Note: When underflow error occurs, the current data in the data buffer of this module is transmitted until the next data is filled.

If OIRQ = 1 and OIEN = 1, an interrupt occurs. * TRMD = 0 (Receive mode) If OIRQ = 1, SSIRDR was not read before there was new unread data written to it. This will lead to the loss of a sample 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. * TRMD = 1 (Transmit mode) If OIRQ = 1, SSITDR had data written to it before it was transferred to the shift register.

The bus format can be selected from one of the eight major modes shown in table 18.3.

It supports Philips, Sony and Matsushita modes 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 the SSI 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 the SSI module, operation is not guaranteed. (3) 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 the SSI module. If the incoming data does not follow the configured format, operation is not guaranteed. (4) 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 the SSI module. (5) Operating Setting Related to Word Length All bits related to the SSICR's word length are valid in non-compressed modes. There are many configurations the SSI module supports, but some of the combinations are shown below for the popular formats by Philips, Sony, and Matsushita.

The SSI module supports the transfer of 4, 6 and 8 channels by using the CHNL, SWL and DWL bits only when the system word length (SWL) is greater than or equal to the data word length (DWL) multiplied by channels (CHNL). Table 18.4 shows the number of padding bits for each of the valid setting. If setting is not valid, "" is indicated instead of a number.

When the SSI module acts as a receiver, each word received by the serial audio bus is read in the order received from the SSIRDR register. Figures 18.7 to 18.9 show how 4, 6 and 8 channels are transferred to the serial audio bus. Note that there are no padding bits in the first example, the second example is left-aligned and the third is right-aligned. This selection is arbitrary and is just for demonstration purposes only.

Figure 18.19 shows how the module enters each of these modes.

All required configuration fields in the control register should be defined in this mode, before the SSI module is enabled by setting the EN bit. Setting the EN bit 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 18.4.4, Transmit Operation and section 18.4.5, Receive Operation, below. Rev. 3.00 Sep. 28, 2009 Page 903 of 1650 REJ09B0313-0300 Section 18 Serial Sound Interface (SSI) 18.4.4 Transmit Operation Transmission can be controlled either by DMA or interrupt. 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 the DMAC has finished its transfer. The alternative method is using the interrupts that the SSI module generates to supply data as required. This mode has a higher interrupt load as the module is only double buffered and will require data to be written at least every system word period. When disabling the module, the SSI clock* must remain present until the SSI module is in idle state, indicated by the IIRQ bit. Figure 18.20 shows the transmit operation in DMA control mode, and figure 18.21 shows the transmit operation in interrupt control mode. Note: * Input clock from the SSISCK pin when SCKD = 0. Oversampling clock when SCKD = 1.

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 the SSI 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 the SSI module is indicating will be received next, and so resynchronize with the audio data stream. 18.4.6 Temporary Stop and Restart Procedures in Transmit Mode The following procedures can be used for implementation. (1) Procedure for the transfer and stop without having to reconfigure the DMAC 1. Set SSICR.DMEN = 0 (disabling a DMA request) to stop the DMA transfer. 2. Wait for SSISR.DIRQ = 1 (transmit mode: the transmit buffer is empty) using a polling, interrupt, or the like. 3. With SSICR.EN = 0 (disabling an SSI module operation), stop the transfer. 4. Before attempting another transfer, make sure that SSISR.IDST = 1 is reached. 5. Set SSICR.EN = 1 (enabling an SSI module operation). 6. Wait for SSISR.DIRQ = 1, using a polling, interrupt, or the like. 7. Setting SSICR.DMEN = 1 (enabling a DMA request) will restart the DMA transfer. (2) Procedure for Reconfiguring the DMAC after an SSI stop 1. Set SSICR.DMEN = 0 (disabling a DMA request) to stop the DMA transfer. 2. Wait for SSISR.DIRQ = 1 (transmit mode: the transmit buffer is empty), using a polling, interrupt, or the like. 3. With SSICR.EN = 0 (disabling an SSI module operation), stop the transfer. 4. Stop the DMAC with CHCR of the DMAC. 5. Before attempting another transfer, make sure that SSISR.IDST = 1 is reached. 6. Set SSICR.EN = 1 (enabling an SSI module operation). 7. Set the DMAC registers and start the transfer. 8. Setting SSICR.DMEN = 1 (enabling a DMA request) will restart the DMA transfer. Rev. 3.00 Sep. 28, 2009 Page 910 of 1650 REJ09B0313-0300 Section 18 Serial Sound Interface (SSI) 18.4.7 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), the SSI 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), the SSI module is in clock master mode, and the shift register uses the oversampling clock, or the bit clock that is generated by dividing it. The oversampling clock is then divided by the ratio in the serial oversampling clock divide ratio bit (CKDV) in SSICR and used as the bit clock in the shift register. In either case the module pin, SSISCK, is the same as the bit clock. Rev. 3.00 Sep. 28, 2009 Page 911 of 1650 REJ09B0313-0300 Section 18 Serial Sound Interface (SSI) 18.5 Usage Notes 18.5.1 Limitations from Underflow or Overflow during DMA Operation If an underflow or overflow occurs while the DMA is in operation, the module should be restarted. The transmit and receive buffers in the SSI 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 two types of error interrupts (underflow, overflow) or the corresponding error status flag (the bits UIRQ, OIRQ in SSISR), write 0 to the EN and DMEN 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.

It serves to facilitate the hardware/software interface so that engineers involved in the RCAN-TL1 implementation can ensure the design is successful. 19.1.2 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 the RCAN-TL1 module in terms of process, packaging or power supply criteria. These issues are resolved where appropriate in implementation specifications. 19.1.3 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 the RCAN-TL1 user interface LSI engineers must use this document to understand the hardware requirements. 19.1.4 References 1.

The module is formed from 5 different functional entities. These are the Micro Processor Interface (MPI), Mailbox, Mailbox Control, Timer, and CAN Interface. The figure below shows the block diagram of the RCAN-TL1 Module. The bus interface timing is designed according to the peripheral bus I/F required for each product.

Longword (32-bit) accesses are converted into two consecutive word accesses by the bus interface. Figure 19.1 RCAN-TL1 architecture Rev. 3.00 Sep. 28, 2009 Page 916 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) Important: Although core of RCAN-TL1 is designed based on a 32-bit bus system, the whole RCAN-TL1 including MPI for the CPU has 16-bit bus interface to CPU. In that case, LongWord (32-bit) access must be implemented as 2 consecutive word (16-bit) accesses. In this manual, LongWord access means the two consecutive accesses. * Micro Processor Interface (MPI) The MPI allows communication between the Renesas CPU and the RCAN-TL1'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 RCAN-TL1 so that the RCAN-TL1 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. Rev. 3.00 Sep. 28, 2009 Page 917 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) * Timer The Timer function is the functional entity, which provides RCAN-TL1 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.

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 RCAN-TL1 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.

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 Rev. 3.00 Sep. 28, 2009 Page 927 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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 RCAN-TL1 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', RCAN-TL1 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 Rev. 3.00 Sep. 28, 2009 Page 928 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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.

Rev. 3.00 Sep. 28, 2009 Page 929 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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. DLC[3] DLC[2] DLC[1] 0 0 0 0 Data Length = 0 bytes (Initial value) 0 0 0 1 Data Length = 1 byte 0 0 1 0 Data Length = 2 bytes 0 0 1 1 Data Length = 3 bytes 0 1 0 0 Data Length = 4 bytes 0 1 0 1 Data Length = 5 bytes 0 1 1 0 Data Length = 6 bytes 0 1 1 1 Data Length = 7 bytes 1 x x x Data Length = 8 bytes (2) DLC[0] Description Local Acceptance Filter Mask (LAFM) This area is used as Local Acceptance Filter Mask (LAFM) for receive boxes. 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 12 11 10 9 8 7 6 5 4 3 2 STDID_LAFM[10:0] EXTID_LAFM[15:0] H'106 + N*32 1 0 EXTID_ LAFM[17:16] Word/LW LAFM Field Word Figure 19.4 Acceptance filter If a bit is set in the LAFM, then the corresponding bit of a received CAN identifier is ignored when the RCAN-TL1 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: RCAN-TL1 starts to find a matching identifier from Mailbox-31 down to Mailbox-0. As soon as RCAN-TL1 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. Rev. 3.00 Sep. 28, 2009 Page 930 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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 RCAN-TL1 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. Rev. 3.00 Sep. 28, 2009 Page 931 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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) RCAN-TL1 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 Mailboxes 30 and 31, Timestamp captures the TCNTR (Timer Counter Register) value at SOF. Rev. 3.00 Sep. 28, 2009 Page 932 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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 0 R/W Offset[5:0] 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.

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, RCAN-TL1 does not clear the corresponding TXPR bit (among Mailbox-30 to 24) to carry on performing the periodic transmission. In order to stop the periodic transmission, TXPR must be cleared by TXCR. Please note that in this case it is possible that both TXACK and ABACK are set for the same Mailbox if TXACK is not cleared right after completion of transmission. Please refer to figure 19.7.

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'. Bits 10 to 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 RCAN-TL1 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 19.4.1, Test Mode Settings. Please note that the test modes are allowed only for diagnosis and tests and not when RCAN-TL1 is used in normal operation.

If this bit is set, the RCAN-TL1 automatically cancels the sleep mode (MCR5) by detecting CAN bus activity (dominant bit). If MCR7 is cleared the RCAN-TL1 does not automatically cancel the sleep mode. RCAN-TL1 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, RCAN-TL1 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. Rev. 3.00 Sep. 28, 2009 Page 940 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) Bit 5 -- Sleep Mode (MCR5): Enables or disables Sleep mode transition. If this bit is set, while RCAN-TL1 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, RCAN-TL1 will ignore all CAN bus activities until the sleep mode is terminated. When leaving this mode the RCAN-TL1 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, RCAN-TL1 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: RCAN-TL1 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 RCAN-TL1 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 RCAN-TL1 sleep mode released (Initial value) 1 Transition to RCAN-TL1 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 Rev. 3.00 Sep. 28, 2009 Page 941 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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). The RCANTL1 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, RCAN-TL1 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 RCAN-TL1 enters BusOff. In the Halt mode, the RCAN-TL1 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 re-join the CAN bus. After this bit has been cleared, RCAN-TL1 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 Rev. 3.00 Sep. 28, 2009 Page 942 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) Bit 0 -- Reset Request (MCR0): Controls resetting of the RCAN-TL1 module. When this bit is changed from `0' to `1' the RCAN-TL1 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. RCAN-TL1 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, the RCAN-TL1 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 RCAN-TL1 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 RCAN-TL1. * 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 the RCAN-TL1 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.

Bit 15: IRR15 Description 0 Timer Compare Match has not occurred to the TCMR1 (Initial value) [Clearing condition] Writing 1 1 Timer Compare Match has occurred to the TCMR1 [Setting condition] TCMR1 matches to Cycle Time (TCMR1 = CYCTR) Bit 14 -- Timer Compare Match Interrupt 0 (IRR14): Indicates that a Compare-Match condition occurred to the Timer Compare Match Register 0 (TCMR0).

It indicates that: The Timer (TCNTR) has overrun when RCAN-TL1 is working in event-trigger mode (including test modes) Rev. 3.00 Sep. 28, 2009 Page 951 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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 the RCAN-TL1 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.

Bit 11: IRR11 Description 0 Timer Compare Match has not occurred to the TCMR2 (initial value) [Clearing condition] Writing 1 1 Timer Compare Match has occurred to the TCMR2 [Setting condition] TCMR2 matches to Cycle Time (TCMR2 = CYCTR) Bit 10 -- Start of new system matrix Interrupt (IRR10): Indicates that a new system matrix is starting. 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. Rev. 3.00 Sep. 28, 2009 Page 953 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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. (Initial value) [Clearing Condition] All the TXACK and ABACK bits are cleared/setting MBIMR for all TXACK and ABACK set 1 Message has been transmitted or aborted, and new message can be stored (in TT mode Mailbox 24 to 30 can be programmed with a new message only in case of abortion) [Setting condition] When a TXACK or ABACK bit is set (if related MBIMR = 0).

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 RCAN-TL1 enters the Bus-off state or when RCAN-TL1 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 the RCAN-TL1 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 RCAN-TL1 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 RCAN-TL1 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 Rev. 3.00 Sep. 28, 2009 Page 955 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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 RCAN-TL1 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 RCAN-TL1 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. Rev. 3.00 Sep. 28, 2009 Page 956 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) Bit 1: IRR1 Description 0 [Clearing condition] Clearing of all bits in RXPR (Initial value) 1 Data frame received and stored in Mailbox [Setting condition] When data is received and the corresponding MBIMR = 0 Bit 0 - Reset/Halt/Sleep Interrupt Flag (IRR0): This flag can get set for three different reasons. 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 RCAN-TL1 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 19.15 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 RCAN-TL1 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 Rev. 3.00 Sep. 28, 2009 Page 957 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) (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 Bits 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, RCAN-TL1 needs to be put into Halt Mode.

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. Rev. 3.00 Sep. 28, 2009 Page 961 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) In Event Triggered Mode RCAN-TL1 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 RCAN-TL1 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, the RCAN-TL1 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 the RCAN-TL1 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. Bits 15 to 0 -- Requests the corresponding Mailbox to transmit a CAN Frame. The bit 15 to 0 corresponds to Mailbox-31 to 16 respectively. When multiple bits are set, the order of the transmissions is governed by the MCR2 - CAN-ID or Mailbox number.

Rev. 3.00 Sep. 28, 2009 Page 963 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) (2) Transmit Cancel Register (TXCR1, TXCR0) The TXCR1 and TXCR0 are 16-bit read/conditionally-write registers. 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.

These registers are used to signal to the CPU that a mailbox transmission has been aborted as per its request. When an abort has succeeded the RCAN-TL1 sets the corresponding bit in the ABACK register. The CPU may clear the Abort Acknowledge bit by writing a `1' to the corresponding bit location. Writing a `0' has no effect. An ABACK bit position is set by the RCAN-TL1 to acknowledge that a TXPR bit has been cleared by the corresponding TXCR bit. * ABACK1 Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 ABACK1[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.

(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.

Bit[15:0]: RFPR0 Description 0 [Clearing Condition] Writing `1' (Initial value) 1 Corresponding Mailbox received Remote Frame [Setting Condition] Completion of remote frame receive in corresponding mailbox (7) Mailbox Interrupt Mask Register (MBIMR) The MBIMR1 and MBIMR0 are 16-bit read/write registers. 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 the RCAN-TL1 from clearing the corresponding TXPR/TXCR bit + setting the TXACK bit for successful transmission, and it does not prevent the RCAN-TL1 from clearing the corresponding TXPR/TXCR bit + setting the ABACK bit for abortion of the transmission. A mask is set by writing a `1' to the corresponding bit position for the mailbox activity to be masked. At reset all mailbox interrupts are masked. * MBIMR1 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 MBIMR1[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 Bits 15 to 0 -- Enable or disable interrupt requests from individual Mailbox-31 to Mailbox-16 respectively.

If the CPU has not cleared the corresponding bit in the RXPR or RFPR when a new message for that mailbox is received, the corresponding UMSR bit is set to `1'. This bit may be cleared by writing a `1' to the corresponding bit location in the UMSR. Writing a `0' has no effect. If a mailbox is configured as transmit box, the corresponding UMSR will not be set. * UMSR1 Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 UMSR1[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.

Its purpose is to store the number of the basic cycle for Time -Triggered Transmissions. Its value is updated in different fashions depending if RCAN-TL1 is programmed to work as a potential time master or as a time slave. If RCAN-TL1 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 RCAN-TL1 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 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 Bits 15 to 6: Reserved.

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). Bits 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 0 R 0 R 0 R 0 R 0 R 0 R 0 R 0 R Rev. 3.00 Sep. 28, 2009 Page 983 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) (8) 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 Bits 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 RCAN-TL1 is not in the halt status.

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 Rev. 3.00 Sep. 28, 2009 Page 988 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) Normal Mode: RCAN-TL1 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, 1) Output is disabled so that RCAN-TL1 does not generate error frames or acknowledgment bits. IRR13 is set when a message error occurs. Self Test Mode 1: RCAN-TL1 generates its own Acknowledge bit, and can store its own messages into a reception mailbox (if required). The CRxn/CTxn (n = 0, 1) pins must be connected to the CAN bus. Self Test Mode 2: RCAN-TL1 generates its own Acknowledge bit, and can store its own messages into a reception mailbox (if required). The CRxn/CTxn (n = 0, 1) pins do not need to be connected to the CAN bus or any external devices, as the internal CTxn (n = 0, 1) is looped back to the internal CRxn (n = 0, 1). CTxn (n = 0, 1) pin outputs only recessive bits and CRxn (n = 0, 1) pin is disabled. Write Error Counter: TEC/REC can be written in this mode. RCAN-TL1 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, RCAN-TL1 can be forced to become an Error Warning by writing a value greater than 95 into them. RCAN-TL1 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: RCAN-TL1 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, RCAN-TL1 will enter BusOff if TEC reaches 256 (Dec). However when this mode is used RCAN-TL1 will not be able to become Error Active. Consequently, at the end of the Bus Off recovery sequence, RCAN-TL1 will move to Error Passive and not to Error Active. When message error occurs, IRR13 is set in all test modes. Rev. 3.00 Sep. 28, 2009 Page 989 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 19.4.2 Configuration of RCAN-TL1 RCAN-TL1 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 RCAN-TL1 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 the RCAN-TL1 after (S/W or H/W) reset. After reset, all the registers are initialised, therefore, RCAN-TL1 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? IRR[0] = 1, GSR[3] = 1 (automatically) Yes Clear IRR[0] Bit RCAN-TL1 is in Tx_Rx Mode Configure MCR[15] - Set TXPR to start transmission - or stay idle to receive Clear Required IMR Bits RCAN-TL1 Timer Reg Setting Mailbox Setting (STD-ID, EXT-ID, LAFM, DLC, RTR, IDE, MBC, MBIMR, DART, ATX, NMC, Tx-Trigger Time Message-Data)*2 Transmission_Reception (Tx_Rx) Mode Detect 11 recessive bits and Join the CAN bus activity Receive*3 Transmit*3 Timer Start*4 Set Bit Timing (BCR) Clear MCR[0] Notes: 1. 2. 3. 4. 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 19.14 Reset Sequence Rev. 3.00 Sep. 28, 2009 Page 990 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) * Halt mode When RCAN-TL1 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 the RCAN-TL1 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 RCAN-TL1 transit to Halt Mode, GSR4 is set. Once the configuration is completed the Halt request needs to be released. RCAN-TL1 will join CAN Bus activity after the detection of 11 recessive bits on the CAN Bus. * Sleep mode When RCAN-TL1 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. Rev. 3.00 Sep. 28, 2009 Page 991 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) The following diagram shows the flow to follow to move RCAN-TL1 into sleep mode.

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 RCAN-TL1 moves to Bus Off and MCR14 and MCR6 are both set. 4. When MCR5 is cleared and MCR1 is set at the same time, RCAN-TL1 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). Mailbox[x] is ready to be updated for next transmission RCAN-TL1 is in Tx_Rx Mode (MBC[x] = 0) Update Message Data of Mailbox[x] Clear TXACK[x] Yes Write '1' to the TXPR[x] bit at any desired time Internal Arbitration 'x' Highest Priority?

Yes Transmission Start CAN Bus Arbitration End Of Frame CAN Bus Figure 19.16 Transmission request * Internal Arbitration for transmission The following diagram explains how RCAN-TL1 manages to schedule transmission-requested messages in the correct order based on the CAN identifier. `Internal arbitration' picks up the highest priority message amongst transmit-requested messages. Rev. 3.00 Sep. 28, 2009 Page 995 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) Transmission Frame-1 CAN bus state RCAN-TL1 scheduler state Bus Idle SOF EOF Interm SOF Message Tx Arb for Tx/Rx Arb for Frame-1 Frame-1 Reception Frame-2 Tx Arb for Frame-3 Transmission Frame-3 EOF Interm SOF Message Tx/Rx Arb for Frame-3/2 Tx Arb for Frame-3 Tx/Rx Arb for Frame-3 Scheduler start point TXPR/TXCR/ Error/Arb-Lost Set Point 1-1 Interm: SOF: EOF: Message: 1-2 2-1 2-2 3-1 3-2 Intermission Field Start Of Frame End Of Frame Arbitration + Control + Data + CRC + Ack Field Figure 19.17 Internal Arbitration for transmission The RCAN-TL1 has two state machines. 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, RCAN-TL1 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, RCAN-TL1 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, RCAN-TL1 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. Bit 6 in TTCR0 has to be cleared to prevent TCNTR from being cleared after a match. 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 RCAN-TL1 can be used to handle the main functions requested by the TTCAN standard. TCNTR Local Time RFMK Ref_Mark CYCTR Cycle Time = TCNTR - RFMK RFTROFF Ref_Trigger_Offset for Mailbox-30 Mailbox-31 Mailbox dedicated to the reception of time reference message Mailbox-30 Mailbox dedicated to the transmission of time reference message when working as a potential time master Mailbox-29 to 24 Mailboxes supporting time-triggered transmission Mailbox-23 to 16 Mailboxes supporting reception without timestamp (may also be implemented as Mailboxes supporting Event Triggered transmission) Mailbox-15 to 0 Mailboxes supporting reception with timestamp timestamp (may also be implemented as Mailboxes supporting Event Triggered transmission) Tx-Trigger Time Time_Mark to specify when a message should be transmitted Rev. 3.00 Sep. 28, 2009 Page 997 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) CMAX Specifies the maximum number of basic cycles when working as potential time master TEW Specify the width of Tx_Enable TCMR0 Init_Watch_Trigger (compare match with Local Time) TCMR1 Compare match with Cycle Time to monitor users-specified events TCMR2 Watch_Trigger (compare match with Cycle Time).

TEW in the following expressions is the register value. TTT (Mailbox-24) < TTT (Mailbox-25) < TTT (Mailbox-26) < TTT (Mailbox-27) < TTT (Mailbox-28) < TTT (Mailbox-29) < TTT (Mailbox-30) and TTT (Mailbox-i) - TTT (Mailbox- i-1) > TEW + the maximum frame length + 9 TTT (Mailbox-24) to TTT (Mailbox-29) correspond to Time_Marks, and TTT (Mailbox-30) corresponds to Time_Ref showing the length of a basic cycle, respectively when working as potential time master.

Change from Init_Watch_Trigger to Watch_Trigger RCAN-TL1 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.

Rev. 3.00 Sep. 28, 2009 Page 1003 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) If, at any time, a reference message cannot be detected on the CAN Bus, and the cycle time CYCTR reaches TCMR2, RCAN-TL1 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 19.21 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, RCAN-TL1 immediately transfers the message into the Tx buffer. At this point, RCAN-TL1 will attempt a transmission within the specified Time Enable Window. If RCAN-TL1 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 RCAN-TL1 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 Rev. 3.00 Sep. 28, 2009 Page 1004 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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. RCAN-TL1 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 RCANTL1 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 19.22 Example of Time trigger system as Time Slave Rev. 3.00 Sep. 28, 2009 Page 1005 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) 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.

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 19.24 Message receive sequence Rev. 3.00 Sep. 28, 2009 Page 1009 of 1650 REJ09B0313-0300 Section 19 Controller Area Network (RCAN-TL1) When RCAN-TL1 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 RCAN-TL1 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) th to 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 RCAN-TL1 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 RCAN-TL1 will not be able to receive/transmit messages during the Halt state. In case RCAN-TL1 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. RCAN-TL1 will not lose a message if the message is currently on the CAN bus and RCANTL1 is a receiver. RCAN-TL1 will be moving into Halt Mode after completing the current reception. Please note that it might take longer if RCAN-TL1 is receiving or transmitting a message (as the transition to the halt state is delayed until the end of the reception/transmission), and also RCAN-TL1 will not be able to receive/transmit messages during the Halt Mode. In case RCAN-TL1 is in the Bus Off state the transition to halt mode depends on the configuration of the bit 6 and 14 of MCR.

A Renesas HA13721 transceiver IC and its compatible products are recommended. As the CRx and CTx pins use 3 V, an external level shifter is necessary.

For details on the settings of I/O ports, see section 25, Pin Function Controller (PFC). Two methods are available using three channels of the RCAN-TL1 in this LSI. * Using RCAN-TL1 as a 2-channel module (channels 0 and 1) Each channel has 32 Mailboxes. * Using RCAN-TL1 as a 1-channel module (channels 0 and 1 functioning as a single channel) When the second method is used, see section 19.9.1, Notes on Port Setting for Multiple Channels Used as Single Channel.

When using multiple channels as a single channel, keep the following in mind. CTx0 RCAN0 (32 Mailboxes) CRx0 CTx1 RCAN1 (32 Mailboxes) CRx1 PB9 PB8 Figure 19.30 Connection Example when Using RCAN-TL1 as 1-Channel Module (64 Mailboxes x 1 Channel) 1. 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. 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.

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. 20.4.1 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, MTU2, 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.

Figure 20.2 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, MTU2, 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 20.3 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, MTU2, 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 20.4 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. Rev. 3.00 Sep. 28, 2009 Page 1033 of 1650 REJ09B0313-0300 Section 20 A/D Converter (ADC) 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 MTU2, set the A/D trigger enable bits (TRGS[3:0]). When an external trigger or an A/D conversion request from the MTU2 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. 20.4.5 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 20.5 shows the A/D conversion timing. Table 20.4 indicates the A/D conversion time. As indicated in figure 20.5, 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 20.4. In multi mode and scan mode, the values given in table 20.4 apply to the first conversion. In the second and subsequent conversions, time is the values given in table 20.5.

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 20.6 shows the timing. P ADTRG Internal trigger signal ADST A/D conversion Figure 20.6 External Trigger Input Timing Rev. 3.00 Sep. 28, 2009 Page 1038 of 1650 REJ09B0313-0300 Section 20 A/D Converter (ADC) 20.5 Interrupt Sources and DMAC 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 (DMAC) can be activated by an ADI interrupt depending on the DMAC setting. In this case, an interrupt is not issued to the CPU. If the setting to activate the DMAC has not been made, an interrupt request is sent to the CPU. Having the converted data read by the DMAC in response to an ADI interrupt enables continuous conversion to be achieved without imposing a load on software. In single mode, set the DMAC 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 DMAC transfer all conversion data, set the ADDR where A/D conversion data is stored as the transfer source address, set the number of converted channels as the transfer count, and set the TC bit in the DMA channel control register (CHCR) to 1. When the DMAC is activated by ADI, the ADF bit in ADCSR is automatically cleared to 0 when data is transferred by the DMAC.

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 20.7. 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 20.7, 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 20.7, item (2)). Quantization error is the intrinsic error of the A/D converter and is expressed as 1/2 LSB (figure 20.7, item (3)). Nonlinearity error is the deviation between actual and ideal A/D conversion characteristics between zero voltage and full-scale voltage (figure 20.7, 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 28, Power-Down Modes. 20.7.2 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 = PVss. Do not leave the AVcc and AVss pins open when the A/D converter or D/A 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 (PVss). 3. Setting range of AVref input voltage Set the reference voltage range of the AVref pin as 3.0 V AVref AVcc. 20.7.3 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 AN7), 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 (PVss) 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.

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 20.10). When converting a high-speed analog signal, a low-impedance buffer should be inserted.

Be sure to connect AVss, etc. to an electrically stable GND. Care is also required to insure that filter circuits do not communicate with digital signals on the mounting board (i.e., acting as antennas). 20.7.7 A/D Conversion in Deep Standby Mode Before entering deep standby mode, disable A/D conversion by clearing the ADST bit to 0. If the LSI enters deep standby mode with A/D conversion enabled, the states on the A/D converter pins are not guaranteed. 20.7.8 Note on Usage in Scan Mode and Multi Mode Starting conversion immediately after stopping scan mode or multi mode can cause incorrect conversion results. To continue with conversion in which cases, allow a duration equivalent to the A/D conversion time for one channel to elapse after clearing ADST to 0 before starting conversion (by setting ADST to 1). (The A/D conversion time for one channel differs depending on the peripheral register settings.)

When the DAOE bit in DACR is set to 1, D/A conversion is enabled and the conversion result is output. An operation example of D/A conversion on channel 0 is shown below. Figure 21.2 shows the timing of this operation. 1. Write the conversion data to DADR0. 2. Set the DAOE0 bit in DACR to 1 to start D/A conversion. The conversion result is output from the analog output pin DA0 after the conversion time tDCONV has elapsed. The conversion result continues to be output until DADR0 is written to again or the DAOE0 bit is cleared to 0. The output value is expressed by the following formula: Contents of DADR 256 x AVref 3.

The initial setting is for operation of the D/A converter to be halted. Register access is enabled by canceling module standby mode. For details, see section 28, Power-Down Modes. 21.5.2 D/A Output Hold Function in Software Standby Mode When this LSI enters software standby mode with D/A conversion enabled, the D/A outputs are retained, and the analog power supply current is equal to as during D/A conversion. If the analog power supply current needs to be reduced in software standby mode, clear the DAOE0, DAOE1, and DAE bits to 0 to disable the D/A outputs. 21.5.3 Setting Analog Input Voltage The reliability of this LSI may be adversely affected if the following voltage ranges are exceeded. 1. AVcc and AVss input voltages Input voltages AVcc and AVss should be PVcc - 0.3 V AVcc PVcc and AVss = PVss. Do not leave the AVcc and AVss pins open when the A/D converter or D/A 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 (PVss). 2. Setting range of AVref input voltage Set the reference voltage range of the AVref pin as 3.0 V AVref AVcc. 21.5.4 D/A Conversion in Deep Standby Mode Before entering deep standby mode, disable D/A conversion by clearing all of the DAOE0, DAOE1, and DAE bits to 0. If the LSI enters deep standby mode with D/A conversion enabled, the states on the D/A converter pins are not guaranteed.

To take measures for errors specific to flash memory, the ECC-code generation function and error detection function are available. Note: The flash memory using Multi Level Cell (MLC) technology is not supported by this LSI. 22.1 (1) Features AND-Type Flash Memory Interface * Interface directly connectable to AND-type flash memory * Read or write in sector units (512 + 16 bytes) and ECC processing executed An access unit of 2048 + 64 bytes, referred to as a page, is used in some datasheets for ANDtype flash memory. In this manual, an access unit of 512 + 16 bytes, referred to as a sector, is always used. For products in which 2048 + 64 bytes is referred to as a page, a page is divided into units of 512 + 16 bytes (i.e. four sectors per page) for processing. * Read or write in byte units * Supports addresses for 2 Gbits and more by extension to 5-byte addresses (2) NAND-Type Flash Memory Interface * Interface directly connectable to NAND-type flash memory * Read or write in sector units (512 + 16 bytes) and ECC processing executed An access unit of 2048 + 64 bytes, referred to as a page, is used in some datasheets for NANDtype flash memory. In this manual, an access unit of 512 + 16 bytes, referred to as a sector, is always used. For products in which 2048 + 64 bytes is referred to as a page, a page is divided into units of 512 + 16 bytes (i.e. four sectors per page) for processing. * Read or write in byte units * Supports addresses for 2 Gbits and more by extension to 5-byte addresses Rev. 3.00 Sep. 28, 2009 Page 1053 of 1650 REJ09B0313-0300 Section 22 AND/NAND Flash Memory Controller (FLCTL) (3) Access Modes: The FLCTL can select one of the following two access modes. * Command access mode: Performs an access by specifying a command to be issued from the FLCTL to flash memory, address, and data size to be input or output. Read, write, or erasure of data without ECC processing can be achieved. * Sector access mode: Performs a read or write in sector units by specifying a sector and controls ECC-code generation and check. By specifying the number of sectors, the continuous sectors can be read or written. (4) Sectors and Control Codes * A sector is the basic unit of access and comprised of 512-byte data and 16-byte control code. The 16-byte control code includes 8-byte ECC. * The position of the ECC in the control code can be specified in 4-byte units. * User information can be written to the control code other than the ECC. (5) ECC * 8-byte ECC code is generated and error check is performed for a sector (512-byte data + 16byte control code). (Note that the ECC code generation in the 16-byte control code and the number of bytes to be checked differ depending on the specifications.) * Error correction capability is up to three errors. * In a write operation, an ECC code is generated for data and control code prior to the ECC. The control code following the ECC is not considered. * In a read operation, an ECC error is checked for data and control code prior to the ECC. An ECC on the control code in the FIFO is replaced with the check result by the ECC circuit, not an ECC code read from flash memory. * An error correction is not performed even when an ECC error occurs. Error corrections must be performed by software. (6) Data Error * When a program error or erase error occurs, the error is reflected on the error source flags. Interrupts for each source can be specified. * When a read error occurs, an ECC in the control code is other than 0. This read error is reflected on the ECC error source flag. * When an ECC error occurs, perform an error correction, specify another sector to be replaced, and copy the contents of the block to another sector as required.

(8) DMA Transfer * By individually specifying the destinations of data and control code of flash memory to the DMA controller, data and control code can be sent to different areas. (9) Access Time * The operating clock (FCLK) on the pins for the AND-/NAND-type flash memory is generated by dividing the peripheral clock (P). * The division ratio can be specified by the FCKSEL bit and the QTSEL bit in the common control register (FLCMNCR). * Before changing the CPG specification, the FLCTL must be placed in a module stop state. * In NAND-type flash memory, the FSC and FWE pins operate with the FCLK frequency. In AND-type flash memory, the FSC pin operates with the FCLK operating frequency and the FWE pin operates with a frequency half the FCLK operating frequency. The operating frequencies must be specified within the maximum operating frequency of memory to be connected.

In programming, an ECC is added. In read, an ECC error check (detection) is performed. Since 512-byte data is stored in FLDTFIFO and 16-byte control code is stored in FLECFIFO, the DREQ1EN and DREQ0EN bits in FLINTDMACR can be set to transfer by the DMA. Figure 22.14 shows the relationship of DMA transfer between sectors in flash memory (data and control code) and memory on the address space.

The FLCTL, however, does not perform error correction. Note that errors must be corrected by software. Rev. 3.00 Sep. 28, 2009 Page 1092 of 1650 REJ09B0313-0300 Section 22 AND/NAND Flash Memory Controller (FLCTL) 22.4.7 Status Read The FLCTL can read the status register of an AND-type or NAND-type flash memory. The data in the status register of an AND-type or NAND-type flash memory is input through the I/O7 to I/O0 pins and stored in the bits STAT[7:0] in FLBSYCNT. The bits STAT[7:0] in FLBSYCNT 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. (1) Status Read of AND-Type Flash Memory The status register of AND-type flash memory can be read by asserting the output enable signal OE (OE = 0). If programming is executed in command access mode or sector access mode while the DOSR bit in FLCMDCR is set to 1, the FLCTL automatically asserts the OE signal and reads the status register of AND-type flash memory. When the status register of AND-type flash memory is read, the I/O7 to I/O0 pins indicate the following information as described in table 22.3. Table 22.3 Status Read of AND-Type Flash Memory I/O Status (definition) Description I/O7 Ready/busy 0: Busy state 1: Ready state I/O6 Reserved I/O5 Erase check 0: Pass (erased) 1: Fail (erase failure) I/O4 Program check 0: Pass (programmed) 1: Fail (program failure) I/O3 to I/O0 Reserved Rev. 3.00 Sep. 28, 2009 Page 1093 of 1650 REJ09B0313-0300 Section 22 AND/NAND Flash Memory Controller (FLCTL) (2) 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, the FLCTL 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 22.4. Table 22.4 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 I/O5 to I/O1 Reserved I/O0 Program/erase 0: Pass 1: Ready state 1: Fail Rev. 3.00 Sep. 28, 2009 Page 1094 of 1650 REJ09B0313-0300 Section 22 AND/NAND Flash Memory Controller (FLCTL) 22.5 Interrupt Sources The FLCTL has six interrupt sources: Status error, ready/busy timeout error, ECC 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, ready/busy timeout error, and ECC error use the common FLSTE interrupt to the CPU. Table 22.5 FLCTL Interrupt Requests Interrupt Source Interrupt Flag Enable Bit Description Priority FLSTE interrupt STERB STERINTE Status error Highest BTOERB RBERINTE Ready/busy timeout error ECERB ECERINTE ECC error FLTEND interrupt TREND TEINTE Transfer end FLTRQ0 interrupt TRREQF0 TRINTE0 FIFO0 transfer request FLTRQ1 interrupt TRREQF1 TRINTE1 FIFO1 transfer request Lowest Rev. 3.00 Sep. 28, 2009 Page 1095 of 1650 REJ09B0313-0300 Section 22 AND/NAND Flash Memory Controller (FLCTL) 22.6 DMA Transfer Specifications The FLCTL can request DMA transfers separately to the data area FLDTFIFO and control code area FLECFIFO. Table 22.6 summarizes DMA transfer enable or disable states in each access mode. Table 22.6 DMA Transfer Specifications Sector Access Mode Command Access Mode FLDTFIFO DMA transfer enabled DMA transfer enabled FLECFIFO DMA transfer enabled DMA transfer disabled In little endian form, these bits should not be used because a 16-byte DMA transfer causes a data replacement in longword units. For details on DMAC settings, see section 10, Direct Memory Access Controller (DMAC). 22.7 (1) Usage Notes Usage Notes for the SNAND bit When using the SNAND bit in FLCMNCR, only the first command or the second command is corresponded in spite of the setting of the DOCMD1 or DOCMD2 bit in FLCMDCR. When no command or only the first command is issued, 0 should be written in the SNAND bit.

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. 0: Outputs no signals 1: Outputs a remote wakeup signal 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 USBCLK must not be stopped even in the suspended state. 7 RWUPE 0 R/W Wakeup Detection Enable Outputs a resume signal to a down port when a remote wakeup signal is detected, by setting this bit to 1.

There are three FIFO ports: the CFIFO, D0FIFO and D1FIFO ports. Each FIFO port is configured of a port register that handles reading of data from the buffer memory and writing of data to the buffer memory, a select register that is used to select the pipe assigned to the FIFO port, a control register, and registers used specially for port functions (an SIE register used exclusively for the CFIFO port and a transaction counter register used exclusively for the DnFIFO port). These registers are initialized by a power-on reset or a software reset.

Notes: 1. The DCP can access the buffer memory only through the CFIFO port. Accessing the buffer memory using DMA transfer can be performed only through the D0FIFO and D1FIFO ports. 2. Accessing the DnFIFO port using the CPU must be performed in conjunction with the functions and restrictions of the DnFIFO port (using the transaction counter, etc.). 3. When using functions specific to the FIFO port, the selected pipe cannot be changed (using the transaction counter, etc.). 4. Registers configuring a FIFO port do not affect other FIFO ports. 5. The same pipe should not be assigned to two or more FIFO ports. 6. There are two sorts of buffer memory states: the access right is on the CPU side and it is on the SIE side. When the buffer memory access right is on the SIE side, the memory cannot be properly accessed from the CPU. 7. The pipe configuration of the pipe selected for the FIFO port should not be changed.

Before using this bit, the following settings are required: * When isochronous-IN transfer is started (1) Set the IFIS bit to 1. (2) Set the PID1 and PID0 bits in PIPEnCTR to 01 (BUF). (3) Write transmit data to the Iso-IN PIPE FIFO buffer. When the IFIS bit is not used for transfer, the above procedures are not required. * When isochronous-IN transfer is ended (1) Clear the PID1 and PID0 bits to 00 (NAK). (2) Set the ACLRM bit in PIPEnCTR to 1. (3) Wait at least 100 ns. (4) Clear the ACLRM bit to 0. When the IFIS bit is not used for transfer, ACLRM setting is not required.

These bits are valid only when the function controller function and isochronous transfer are selected. In other words, these bits can be set when PIPE1 and PIPE2 are selected. * OUT-direction: When this module does not receive the OUT token from the host until the time indicated by these bits, it detects an interval error on the NRDY interrupt and generates the NRDY interrupt. * IN-direction: When this module does not receive the IN token from the host until the time indicated by these bits, it flushes (clears) the buffer if IFIS = 1. When the host controller function is selected, these bits are valid for isochronous transfers and interrupt transfers.

If the SQCLR and SQSET bits in this register and DCPCTR are being used to change the data PID sequence toggle bit for several pipes in succession, an access cycle of 120 ns and 5- or more bus clock cycles is required. 3. The SQCLR bit and SQSET bits should not be set to 1 at the same time. Before operating either bit, PID = NAK should be set. If isochronous transfer is set for the transfer type (TYPE = 11), writing to the SQSET bit is invalid.

(1) Resets Table 23.10 lists the types of controller resets. For the initialized states of the registers following the reset operations, see section 23.3, Register Description. Table 23.10 Types of Reset Name Operation Power-on reset Low level input from the RES pin Software reset Operation using the USBE bit in SYSCFG 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. (3) Enabling High-Speed Operation This module can select a USB communication speed (communication bit rate) of either high-speed or full-speed using software. In order to enable the high-speed operation for this module, the HSE bit in SYSCFG should be set to 1. Changing the HSE bit should be done in the initial settings immediately after a power-on reset or with the D+ line pull-up disabled (DPRPU = 0). 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. Rev. 3.00 Sep. 28, 2009 Page 1170 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (4) USB Data Bus Resistor Control Figure 23.1 shows a diagram of the connections between this module and the USB connectors. 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 DMRPD 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. If a disconnection from the host controller or peripheral device is detected, this module should be initialized by a software reset. 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 control the device connection and disconnection using software with the USB cable being connected. This LSI 5V (Host side) Impedance control has to be taken into consideration when designing the D+ and D- lines.

Table 23.12 shows the conditions under which this module sets 1 to a corresponding bit in BRDYSTS. Under this condition, this module generates BRDY interrupt, if software sets the PIPEBRDYE bit in BRDYENB that corresponds to the pipe to 1 and the BRDYE bit in INTENB0 to 1. Figure 23.3 shows the timing at which the BRDY interrupt is generated. The conditions for clearing the BRDY bit in INTSTS0 by this module depend on the setting of the BRDYM bit in INTENB1. Table 23.13 shows the conditions. When the function controller function is selected, under condition 1 noted below, a zero-length packet is always transmitted for an IN token, and the BRDY interrupt is not generated. 1. When the transfer type is set to bulk IN transfer, PID is set to BUF, and the ATREPM bit in PIPEnCTR is set to H'01.

In continuous transfer (CNTMD = 1), it means that the buffer size of data has been received. If a zero-length packet has been received, the corresponding bit in BRDYSTS is set to 1 but data in the corresponding packet cannot be read. The buffer should be cleared (BCLR = 1) after clearing BRDYSTS. With PIPE1 to PIPE7, if DMA transfer is performed in the reading direction, interrupts can be generated in transfer units, by setting the BFRE bit in PIPECFG to 1.

In this case, this module issues the NRDY interrupt if software sets the PIPENRDYE bit in NRDYENB corresponding to the pipe and the NRDYE bit in INTENB0 to 1. When software clears all the bits in NRDYSTS, this module clears the NRDY bit in INTSTS0. (a) When the host controller function is selected: The NRDY interrupt is generated under either of the following conditions. At this time, hardware sets the PID bits to stop issuing a token. For the operation of the PID bits, see section 23.4.3 (4), Response PID. STALL has been received from the peripheral side for the issued token. No response has been returned from the peripheral side for the issued token. An overrun/underrun error has occurred during isochronous transfer. However, a SIGN interrupt will be generated when no ACK response has been returned from the peripheral side in setup transaction. (b) When the function controller function is selected: The NRDY interrupt is generated under the following conditions. 1. For data transmission If an IN token has been received (data underrun) when the PID bit in PIPEnCTR is set to BUF and there are no data waiting to be transmitted in the buffer memory. 2. For data reception If an OUT token or PING token has been received (data overrun) when the PID bit in PIPEnCTR is set to BUF and there are no area in the buffer memory where data can be stored. In a bulk transfer, when the maximum packet size has not been set (MXPS = 0) and an OUT token or a PINK token has been received When a CRC error or bit stuffing error has occurred during isochronous transfer In an isochronous transfer, when a token has been received in a period other than the interval frame (an interval error).

In this case, this module generates a BEMP interrupt if software sets the PIPEBEMPE bit in BEMPENB corresponding to the corresponding pipe and the BEMPE bit in INTENB0 to 1. If software clears all the bits in BEMPSTS, this module clears the BEMP bit in INTSTS0. 1. When the transmitting direction (writing to the buffer memory) has been set When all of the data stored in the buffer memory has been transmitted If the buffer memory is being used as a double buffer, however, the following conditions should be met. A BEMP interrupt is generated if the buffer on one side is empty and transmitting of data from the buffer on the other side has been completed. A BEMP interrupt is generated if data consisting of less than eight bytes is being written to the buffer on one side, and transmitting of data on the other side of the buffer has been completed. 2. When the receiving direction (reading from the buffer memory) has been set If the size of the data packet that was received exceeded the maximum packet size and the maximum packet size is not set to 0 (MXPS 0), this module sets the PID bit of the corresponding pipe to STALL. Figure 23.5 shows the timing at which a BEMP interrupt is generated when the function controller function has been selected.

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.

Figure 23.6 Device State Transitions Rev. 3.00 Sep. 28, 2009 Page 1185 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (5) Control Transfer Stage Transition Interrupt Figure 23.7 shows a diagram of how this module handles the control transfer stage transition. 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 sequence errors are described below. If an error occurs, the PID bit in DCPCTR is set to B'1x (STALL). 1. 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 2. 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 3. 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 (SERR = 1), 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. (This module retains the setup stage end, and after the interrupt status has been cleared by software, a setup stage end interrupt is generated.)

When the frame number is updated or a damaged SOF packet is detected, the SOFR interrupt is generated. The interrupt operation should be specified using the SOFRM bit in FRMNUM. When the host controller function is selected, SOFRM = 1 should not be set. 1. When SOFRM = 0 is set The SOFR interrupt is generated when the frame number is updated (intervals of approximately 1 ms). Interrupts are generated by the internal interpolation function even if an SOF packet is damaged or missing. During high-speed communication, interrupts are generated at the timing at which the frame number is updated (intervals of approximately 1 ms). Rev. 3.00 Sep. 28, 2009 Page 1187 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 2. When SOFRM = 1 is set The SOFR interrupt is generated when SOF packets are damaged or missing. During highspeed communication, interrupts are generated only if the first packet of a SOF packet with the same frame number is damaged or missing. (Corrupted or missing SOFs are recognized by the SOF interpolation function. For details, see section 23.4.9, SOF Interpolation Function.) 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. 1. Conditions under which SOF lock monitoring begins USBE = 1 2. Conditions under which SOF lock monitoring stops USBE = 0 (software reset), a USB bus reset is received, or suspended state is detected.

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 The RESM interrupt is generated when the device state is the suspended state, and the USB bus state has changed (from J-state to K-state, or from J-state to SE0). Recovery from the suspended state is detected by means of the resume interrupt. (9) 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 function 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 device is detected during full-speed operation when the host controller function has been selected. Note that the DTCH interrupt cannot be used in high-speed mode. Clear DTCHE to 0 in high-speed mode. To detect disconnection during high-speed operation, additional processing is necessary, such as performing periodic control transfers of standard requests and determining disconnection if no response is returned from the peripheral side. Detachment in the suspended state can be detected using the BCHG interrupt. (11) SACK Interrupt The SACK interrupt is generated when an ACK response for the transmitted setup packet has been received from the peripheral side with the host controller function selected. The SACK interrupt can be used to confirm that the setup transaction has been completed successfully.

The SIGN interrupt can be used to detect no ACK response transmitted from the peripheral side or corruption of an ACK packet. 23.4.3 Pipe Control Table 23.14 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 eight pipes that are used for data transfer. Settings should be entered for each of the pipes in conjunction with the specifications of the system.

The transfer types that can be set for the pipes are as follows. 1. DCP: No setting is necessary (fixed at control transfer). 2. PIPE1 and PIPE2: These should be set to bulk transfer or isochronous transfer. 3. PIPE3 to PIPE5: These should be set to bulk transfer. 4. PIPE6 and PIPE7: These should be set to interrupt transfer. (2) Endpoint Number The EPNUM bit in PIPECFG is used to set the endpoint number for each pipe. The DCP is fixed at endpoint 0. The other pipes can be set from endpoint 1 to endpoint 15. 1. DCP: No setting is necessary (fixed at end point 0). 2. PIPE1 to PIPE7: The endpoint numbers from 1 to 15 should be selected and set. These should be set so that the combination of the DIR bit and EPNUM bit is unique. (3) Maximum Packet Size Setting The MXPS bit in DCPMAXP and PIPEMAXP is used to specify the maximum packet size for each pipe. DCP and PIPE1 to PIPE5 can be set to any of the maximum pipe sizes defined by the USB specification. For PIPE6 and PIPE7, 64 bytes are the upper limit of the maximum packet size. The maximum packet size should be set before beginning the transfer (PID = BUF). 1. DCP: 64 should be set when using high-speed operation. 2. DCP: Select and set 8, 16, 32, or 64 when using full-speed operation. 3. PIPE1 to PIPE5: 512 should be set when using high-speed bulk transfer. 4. PIPE1 to PIPE5: Select and set 8, 16, 32, or 64 when using full-speed bulk transfer. 5. PIPE1 and PIPE2: Set a value between 1 and 1024 when using high-speed isochronous transfer. 6. PIPE1 and PIPE2: Set a value between 1 and 1023 when using full-speed isochronous transfer. 7. PIPE6 and PIPE7: Set a value between 1 and 64. The high bandwidth transfers used with interrupt transfers and isochronous transfers are not supported.

The following shows this module operation with various response PID settings: * Response PID settings when the host controller function is selected: The response PID is used to specify the execution of transactions. A. NAK setting: Using pipes is disabled. No transaction is executed. B. 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. C. STALL setting: Using pipes is disabled. No transaction is executed. Setup transactions for the DCP are set with the SUREQ bit. * Response PID settings when the function controller function is selected: The response PID is used to specify the response to transactions from the host. A. NAK setting: The NAK response is always returned in response to the generated transaction. B. BUF setting: Responses are made to transactions based on the status of the buffer memory. C. 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. * When the host controller function has been selected and the response PID is set by hardware: A. NAK setting: In the following cases, PID = NAK is set and issuing of tokens is automatically stopped: * When a transfer other than isochronous transfer has been performed and no response is returned to the issued token. * When a corrupted packet is received in response to the transmitted token. * When a short packet is received in the data stage of a control read transfer. Rev. 3.00 Sep. 28, 2009 Page 1193 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) * 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. B. BUF setting: There is no BUF writing by this module. C. 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. * When the function controller function has been selected and the response PID is set by hardware: A. 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. B. BUF setting: There is no BUF writing by this module. C. 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. (5) Registers that Should Not be Set in the USB Communication Enabled (PID = BUF) State * The ISEL bit in CFIFOSEL (applies only when DCP is selected) * The TGL and SCLR bits in CFIFOSIE * The DCLRM, TRENB, TRCLR, and DEZPM bits in DnFIFOSEL * The TRNCNT bit in DxFIFOTRN * Bits in DCPCFG * Bit in DCPMAXP * Bits in DCPCTR (excepting the CCPL bit) * Bits in PIPECFG * Bits in PIPEBUF * Bits in PIPEMAXP * Bits in PIPEPERI Rev. 3.00 Sep. 28, 2009 Page 1194 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) * Bits in PIPEnCTR (6) 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. DATA0 is returned when the setup stage is ended and DATA1 is returned in a status stage. Therefore, software settings are not required. However, when the host controller function has been selected and control transfer is used, the sequence bit should be set by software at the stage transition. For the Clearfeature request transmission or reception, the data PID sequence bit should be set by software, 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. (7) 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) using software. This function can be used only when bulk transfers are used. Rev. 3.00 Sep. 28, 2009 Page 1195 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (8) 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 buffer memory is an area shared by the CPU and this module. In the 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). 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 C/DnFIFOCTR.

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, software can refer the BSTS bit 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 (DMAC) writes data slowly, software can use the INBUFM bit to confirm the end of sending.

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 and PIPE7 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 pipe can be cleared regardless of the access direction. An access cycle of at least 100 ns is required between ACLRM = 1 and ACLRM = 0. (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 23.10 shows an example of buffer memory settings for this 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 23.10 Example of Buffer Memory Settings Rev. 3.00 Sep. 28, 2009 Page 1201 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (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 DCPCFG and PIPEnCFG. This selection is valid for PIPE0 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. Figure 23.11 shows an example of buffer memory operation for this module. CNTMD = 0 When packet is received CNTMD = 1 When packet is received Max Packet Size Max Packet Size Unused area Interrupt issued Max Packet Size CNTMD = 0 When packet is sent CNTMD = 1 When packet is sent Max Packet Size Max Packet Size Unused area Transmission enabled Interrupt issued Max Packet Size Transmission enabled Figure 23.11 Example of Buffer Memory Operation Rev. 3.00 Sep. 28, 2009 Page 1202 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (2) FIFO Port Functions Table 23.19 shows the settings for the FIFO port functions of this module. 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.

Rev. 3.00 Sep. 28, 2009 Page 1203 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (a) FIFO Port Selection Table 23.20 shows the pipes that can be selected with the various FIFO ports. The pipe to be accessed is selected using the CURPIPE bit in C/DnFIFOSEL. After the pipe has been selected, FRDY = 1 should be confirmed before accessing the FIFO port. 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. Table 23.20 FIFO Port Access Categorized by Pipe Pipe Access Method Port that can be Used DCP CPU access CFIFO port register PIPE1 to PIPE7 CPU access CFIFO port register D0FIFO/D1FIFO port register DMA access (b) D0FIFO/D1FIFO port register REW Bit It is possible to temporarily stop access to the pipe currently being accessed, access a different pipe, and then continue processing using the current pipe once again. 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 confirmed after selecting a pipe. (c) Reading the Buffer Memory on the SIE (CFIFO Port Reading Direction) Even in the FRDY = 0 state, when data cannot be read from the buffer memory, confirming the SBUSY bit in CFIFOSIE and setting 1 for the TGL bit makes it possible for this module to read and access data on the SIE side. PID = NAK should be set and SBUSY = 0 confirmed, and then TGL = 1 written. This module is then able to read data from CFIFO. This function can be used only in the buffer memory reading direction. Also, the BRDY interrupt is generated by operation of the TGL bit. Rev. 3.00 Sep. 28, 2009 Page 1204 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 1 should not be written for the TGL bit in the following circumstances. * When DCP is selected * While the buffer memory is being read * Pipes in the buffer memory writing direction (d) Clearing the Buffer Memory on the SIE (CFIFO Port Writing Direction) This module can cancel data that is waiting to be sent, by confirming the SBUSY bit in CFIFOSIE and setting 1 for the SCLR bit. PID = NAK should be set and SBUSY = 0 confirmed, and then SCLR = 1 written. This module is then able to write new data from CFIFO. This function can be used only in the buffer memory writing direction. Also, the BRDY interrupt is generated by the SCLR bit. 1 should not be written for the SCLR bit in the following circumstances. * When DCP is selected * While data is being written to the buffer memory * Pipes in the buffer memory reading direction (e) Transaction Counter (D0FIFO/D1FIFO Port Reading Direction) When the specified number of transactions has been completed in the data packet receiving direction, this module is able to recognize that the transfer has ended. The transaction counter is a function that operates when the pipe selected by means of the D0FIFO/D1FIFO port has been set in the direction of reading data from the buffer memory. The transaction counter has TRNCNT that specifies the number of transactions and a current counter that counts the transactions internally. When the current counter matches the number of transactions specified in TRNCNT, reading is enabled for the buffer memory. 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 by TRNCNT differs depending on the setting of the TRENB bit. * TRENB = 0: The set transaction counter value can be read. * TRENB = 1: The value of the current counter that counts the transactions internally can be read. The conditions for changing the CURPIPE bit are as noted below. * The CURPIPE bit should not be changed until the transaction for the specified pipe has ended. * The CURPIPE bit cannot be changed if the current counter has not been cleared. Rev. 3.00 Sep. 28, 2009 Page 1205 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) The operation conditions for the TRCLR bit are as noted below. * 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. (f) FIFO Port Access Wait Specification Access to FIFO ports in this module has the following restrictions. * Do not exceed a transfer speed of 48 MB/s. This module can limit access cycle through the access wait set (FWAIT) bit so that the peripheral clock frequency is not limited. The FWAIT bit can be set to each FIFO port, and can be efficiently set according to the CPU speed, the transfer source access cycle, and so on. * Conditions Access direction: writing to FIFO Peripheral clock frequency: 66 MHz MBW bit setting value: 10 (32-bit width) Access type: After transfer data is read from the on-chip memory (the source), it is written to the FIFO port. In this case, 2 clock cycles are required for source access. * Example of calculation (2 + (FWAIT + 2)) x 1/66 MHz 1/48 MHz x 4 (32 bits) FWAIT = 2 (4 clock cycles) (g) Methods of Accessing FIFO Port for Fractional-Width Data If a unit of data narrower than the bit width specified by the MBW bits in the FIFO port select register is to be read from a FIFO port, read the data with the bit width specified by the MBW bits and then use software to discard the unnecessary data. If a unit of data narrower than the bit width specified by the MBW bits in the FIFO port select register is to be written to a FIFO port, access the FIFO port as shown in the example below. The example shows how to write 24-bit-wide data when the FIFO port width has been specified as 32 bits (MBW = 10).

When the DCP setting (CURPIPE = 000) is selected in the CFIFO register, set the CURPIPE bits or ISEL bit and write to the MBW bits simultaneously. Follow the procedure below to change the setting of only the MBW bits for the currently selected pipe. However, once a buffer memory read operation has started, do not change the setting of the MBW bits until all the data has been read. It is possible to change the setting of only the MBW bits directly when the selected CURPIPE is set to the buffer memory write direction. However, once a buffer memory write operation has started, do not change the bit width from 8 bits to 16 or 32 bits, or from 16 bits to 32 bits. * When CURPIPE of DFIFO0, DFIFO1, or CFIFO is set to other than DCP (000) Start [1] Set CURPIPE to 000 [2] Insert wait of at least 120 ns + 5 bus cycles [3] Set MBW and CURPIPE simultaneously [1] Set CURPIPE to a setting other than the current setting.

MBW setting change completed Figure 23.14 Example of Changing the MBW Setting when CURPIPE of DFIFO0, DFIFO1, or CFIFO Is Set to Other Than DCP (000) Rev. 3.00 Sep. 28, 2009 Page 1208 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (3) DMA Transfers (D0FIFO/D1FIFO port) (a) Overview of DMA Transfers For pipes 1 to 7, the FIFO port can be accessed using the DMAC. 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. (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. A DMA transfer signal is output from the DMAC when the number of DMA transfers specified in the DMA transfer count register (DMATCR) has been performed. When a DMA transfer end signal is sampled, the module enables buffer memory transmission (the same condition as when BVAL = 1). The TENDE bit in DnFBCFG can be used to specify whether a DMA transfer end signal is sampled or not. (c) Zero-Length Packet Addition Mode (D0FIFO/D1FIFO Port Writing Direction) With this module, it is possible to add and send one zero-length packet after all of the data has been sent, under the condition below, by setting 1 to the DEZPM bit in DnFIFOSEL. This function can be set only if the buffer memory writing direction has been set (a pipe in the sending direction has been set for the CURPIPE bits). * If the number of data bytes written to the buffer memory is a multiple of the integer for the maximum packet size when a DMA transfer end signal is sampled. (d) 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 corresponding pipe when reading of the data from the buffer memory has been completed. Table 23.21 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 by software 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.

When using DMA transfers, this function can be used to generate an interrupt only when the last data item has been received. The last data item refers to the reception of a short packet, or the ending of the transaction counter. When the BFRE bit is set to 1, the BRDY interrupt is generated after the received data has been read. When the DTLN bit in DnFIFOCTR is read, the length of the data received in the last data packet to have been received can be confirmed. Table 23.22 shows the timing at which the BRDY interrupts are generated by this module.

In the writing direction, the BFRE bit should be fixed at 0. (4) Timing at which the FIFO Port can be Accessed (a) Timing at which the FIFO Port can be Accessed when Switching Pipes Figure 23.15 shows a diagram of the timing up to the point where the FRDY and DTLN bits are determined when the pipe specified by the FIFO port has been switched (the CURPIPE bit in C/DnFIFOSEL has been changed). If the CURPIPE bits have been changed, access to the FIFO port should be carried out after waiting 450 ns and 8 clock cycles at a peripheral clock after writing to C/DnFIFOSEL. The same timing applies with respect to the CFIFO port, when the ISEL bit is changed.

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 side (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. 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 DCPCFG. Completion of data transfer is detected using the BRDY and 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, software must control so as to send a zero-length packet at the end. Rev. 3.00 Sep. 28, 2009 Page 1213 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) For data transfers in the sending direction during high-speed operation, the PING packet is sent. Control for the PING packet is done in the same manner as bulk transfers. (c) 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 DCPCFG. 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 in C/DnFIFOCTR. For data transfers in the sending direction during high-speed operation, the PING packet is sent. Control for the PING packet is done in the same manner as the bulk transfers. (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. 1. 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. 2. 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. Rev. 3.00 Sep. 28, 2009 Page 1214 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 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 23.18. (b) 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. 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. For information on the NYET handshake, see section 23.4.6 (2), NYET Handshake Control when the Function Controller Function is Selected. (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. 1. For control read transfers: The zero-length packet is received from the USB host, and this module sends an ACK response. 2. For control write transfers and no-data control transfers: This module sends a zero-length packet and receives an ACK response from the USB host. Rev. 3.00 Sep. 28, 2009 Page 1215 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (d) Control Transfer Auto Response Function This module automatically responds to a normal SET_ADDRESS request. If any of the following errors occur in the SET_ADDRESS request, a response from the software is necessary. 1. Any transfer other than a control read transfer: bmRequestType H'00 2. If a request error occurs: wIndex H'00 3. For any transfer other than a no-data control transfer: wLength H'00 4. If a request error occurs: wValue > H'7F 5. Control transfer of a device state error: DVSQ = 011 (Configured) For all requests other than the SET_ADDRESS request, a response is required from the corresponding software. 23.4.6 Bulk Transfers (PIPE1 to PIPE5) The buffer memory specifications for bulk transfers (single/double buffer setting, or continuous/non-continuous transfer mode setting) can be selected. 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. If MXPS = 0 has been set, the interrupt specifications are different from those of the other pipes. For details, see section 23.4.3 (3), Maximum Packet Size Setting. (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. Reception of an NAK or NYET handshake returns this module to PING packet sending mode. This control also applies to the control transfers in the data stage and status stage. 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. Rev. 3.00 Sep. 28, 2009 Page 1216 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 8. Sends a PING packet. This controller is returned to PING packet sending mode by a power-on reset, a software reset, receiving a NYET/NAK handshake, setting or clearing the sequence toggle bits (SQSET and SQCLR), and setting the buffer clear bit (ACLRM) in PIPEnCTR. (2) NYET Handshake Control when the Function Controller Function is Selected Table 23.23 shows the NYET handshake responses of this module. The NYET response of this module is made in conformance with the conditions noted below. When a short packet is received, however, the response will be an ACK response instead of a NYET packet response. The same applies to the data stages of control write transfers. Table 23.23 NYET Handshake Responses Value Set Buffer for PID Bit in Memory DCPCTR State NAK/STALL BUF Token Response Note SETUP ACK IN/OUT/ PING NAK/STALL SETUP ACK RCV-BRDY1 OUT/PING ACK If an OUT token is received, a data packet is received.

RCV-BRDY2: When an OUT token is received, there is only enough space in the buffer memory for one packet. RCV-NRDY: When a PING token is received, there is no space in the buffer memory. TRN-BRDY: When an IN token is received, there is data to be sent in the buffer memory. TRN-NRDY: When an IN token is received, there is no data to be sent in the buffer memory. Rev. 3.00 Sep. 28, 2009 Page 1217 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 23.4.7 Interrupt Transfers (PIPE6 and PIPE7) 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. 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. * Software 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. (b) Operation when Transmission/Reception is Impossible at Token Issuance Timing This module cannot issue tokens even at token issuance timing in the following cases. 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.

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. Note: When using isochronous OUT transfer, see section 23.5.1, Note on Using Isochronous OUT Transfer. (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 23.24 and 23.25 show the priority in which errors are confirmed and the interrupts that are generated. 1. PID errors If the PID of the packet being received is illegal 2. CRC errors and bit stuffing errors If an error occurs in the CRC of the packet being received, or the bit stuffing is illegal 3. Maximum packet size exceeded The maximum packet size exceeded the set value. 4. Overrun and underrun errors When host controller function is selected: * When using isochronous IN transfers (reception), the IN token was received but the buffer memory is not empty. * 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.

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. Table 23.24 Error Detection when a Token is Received Detection Priority Error Generated Interrupt and Status 1 PID errors No interrupts are generated in both cases when the host controller function is selected and the function controller function is selected (ignored as a corrupted packet). 2 CRC error and bit stuffing errors No interrupts generated in both cases when the host controller function is selected and the function controller function is selected (ignored as a corrupted packet). 3 Overrun and underrun errors An NRDY interrupt is generated to set the OVRN bit in both cases when host controller function is selected and function controller function is selected. 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 Rev. 3.00 Sep. 28, 2009 Page 1220 of 1650 REJ09B0313-0300 An NRDY interrupt is generated when the function controller function is selected. It is not generated when the host controller function is selected. Section 23 USB 2.0 Host/Function Module (USB) Table 23.25 Error Detection when a Data Packet is Received Detection Priority Order Error Generated Interrupt and Status 1 PID errors No interrupts are generated (ignored as a corrupted packet) 2 CRC error and bit stuffing errors An NRDY interrupt is generated to set the CRCE bit in both cases when the host controller function is selected and the function controller function is selected. 3 Maximum packet size exceeded error A BEMP interrupt is generated to set the PID bits to STALL in both cases when the host controller function is selected and the function controller function is selected.

IN direction DATA0: Sent as data packet PID DATA1: Not sent DATA2: Not sent mDATA: Not sent 2. OUT direction (when using full-speed operation) DATA0: Received normally as data packet PID DATA1: Received normally as data packet PID DATA2: Packets are ignored mDATA: Packets are ignored 3. OUT direction (when using high-speed operation) DATA0: Received normally as data packet PID DATA1: Received normally as data packet PID DATA2: Received normally as data packet PID mDATA: Received normally as data packet PID Rev. 3.00 Sep. 28, 2009 Page 1221 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) (3) Interval Counter The isochronous interval can be set using the IITV bits in PIPEPERI. The interval counter enables the functions shown in table 23.26 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 23.26 Functions of the Interval Counter when the Function Controller Function is Selected Transfer Direction Function Conditions for Detection IN IN buffer flush function When a token cannot be normally received in the interval frame during an isochronous IN transfer OUT Notifies that a token not being received When a 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 isochronism 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) Counter Initialization when the Function Controller Function is Selected This module initializes the interval counter under the following conditions. 1. Power-on reset The IITV bit is initialized. 2. Software reset The IITV bit is initialized. 3. USB bus reset The IITV bit is not initialized, but the counting is initialized. 4. 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. Rev. 3.00 Sep. 28, 2009 Page 1222 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 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. The interval counter is not initialized under the conditions noted below. 1. 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 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. (4) Setup of Data to be Transmitted using Isochronous Transfer when the Function Controller Function is Selected With isochronous data transmission using this module in function controller function, after data has been written to the buffer memory, a data packet can be sent with the next frame in which an SOF packet is detected. 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 23.17 shows an example of transmission using the isochronous transfer transmission data setup function with this module, when IITV = 0 (every frame) has been set. Sending of a zerolength packet is displayed in the figure as Null, in a shaded box. Rev. 3.00 Sep. 28, 2009 Page 1223 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) Received token Buffer A IN Empty IN IN Writing ended Writing Transfer enabled Empty Empty Buffer B Sent packet Null Null Data-A SOF packet Buffer A Empty Writing Empty Buffer B Received token Buffer A Empty Writing Empty Sent packet Sent packet Writing ended Writing Null Received token Buffer B Writing ended Writing IN Buffer B Buffer A Transfer enabled Writing ended IN Transfer enabled Writing Empty Writing ended Writing Null Empty Writing ended Writing Transfer enabled Writing ended Data-A IN Empty IN Data-B IN IN Transfer enabled Empty IN Writing ended Writing Transfer enabled Writing ended Data-A Empty Null Empty Data-B Figure 23.17 Example of Data Setup Function Operation (5) Isochronous Transfer Transmission Buffer Flush when the Function Controller Function Is Selected If an SOF packet or a SOF packet is received without receiving an IN token in the interval frame during isochronous data transmission, this module operates as if an IN token had been corrupted, and clears the buffer for which transmission is enabled, putting that buffer in the writing enabled state. 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. The timing at which the operation of the buffer flush function varies depending on the value set for the IITV bit. Rev. 3.00 Sep. 28, 2009 Page 1224 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 1. If IITV = 0 The buffer flush operation starts from the next frame after the pipe becomes valid. 2. In any cases other than IITV = 0 The buffer flush operation is carried out subsequent to the first normal transaction. Figure 23.18 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. Buffer A Empty Empty Buffer B Writing Writing ended Transfer enabled Writing Writing ended Empty Writing Writing ended Transfer enabled Figure 23.18 Example of Buffer Flush Function Operation Figure 23.19 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. OUT direction: If the buffer is in the reception enabled state, the data is received as a normal response. If the buffer is in the reception disabled state, the data is discarded and an overrun error occurs.

The SOF interpolation operation begins when USBE = 1, SCKE = 1 and an SOF packet is received. The interpolation function is initialized under the following conditions. * Power-on reset * Software 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 the USB 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.) Rev. 3.00 Sep. 28, 2009 Page 1226 of 1650 REJ09B0313-0300 Section 23 USB 2.0 Host/Function Module (USB) 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. * Refreshing of the frame number and the micro-frame number * SOFR interrupt timing and SOF lock * Isochronous transfer interval count If an SOF packet is missing when full-speed operation is being used, the FRNM bit in FRMNUM0 is not refreshed. If a SOF packet is missing during high-speed operation, the UFRNM bit in FRMNUM1 is refreshed. However, if a SOF packet for which the FRNM = 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 FRNM = 000 are received normally.

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.

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, 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 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.

The LCDC module reads data from system memory, uses the palette memory to determine the colors, then puts the display on the LCD panel. It is possible to connect the LCDC to the LCD module* other than microcomputer bus interface types and NTSC/PAL types and those that apply the LVDS interface. Note: * LCD module can be connected to the LVDS interface by using the LSI with LVDS conversion LSI. 24.1 Features The LCDC has the following features. * Panel interface Serial interface method 1 Supports data formats for STN/dual-STN/TFT panels (8/12/16/18-bit bus width)* * Supports 4/8/15/16-bpp (bits per pixel) color modes * Supports 1/2/4/6-bpp grayscale modes 2 * Supports LCD-panel sizes from 16 x 1 to 1024 x 1024* * 24-bit color palette memory (16 of the 24 bits are valid; R:5/G:6/B:5) * STN/DSTN panels are prone to flicker and shadowing. The controller applies 65536-color control by 24-bit space-modulation FRC with 8-bit RGB values for reduced flicker. * Dedicated display memory is unnecessary using part of the synchronous DRAM (area 3) as the VRAM to store display data of the LCDC. * The display is stable because of the large 2.4-kbyte line buffer * Supports the inversion of the output signal to suit the LCD panel's signal polarity * Supports the selection of data formats (the endian setting for bytes, backed pixel method) by register settings * An interrupt can be generated at the user specified position (controlling the timing of VRAM update start prevents flicker) * A hardware-rotation mode is included to support the use of landscape-format LCD panels as portrait-format LCD panels (the horizontal width of the panel before rotation must be within 320 pixels (see table 24.5.) Notes: 1. When connecting the LCDC to a TFT panel with an unwired 18-bit bus, the lower bit lines should be connected to GND or to the lowest bit from which data is output. 2.

There are three LCD panel types: STN, DSTN, and TFT. There are four data bus widths for output to the LCD panel: 4, 8, 12, and 16 bits. When the required data bus width for a TFT panel is 16 bits or more, connect the LCDC and LCD panel according to the data bus size of the LCD panel. Unlike in a TFT panel, in an STN or DSTN panel, the data bus width setting does not have a 1:1 correspondence with the number of display colors and display resolution, e.g., an 8-bit data bus can be used for 16 bpp, and a 12-bit data bus can be used for 4 bpp. This is because the number of display colors in an STN or DSTN panel is determined by how data is placed on the bus, and not by the number of bits. For data specifications for an STN or DSTN panel, see the specifications of the LCD panel used. The output data bus width should be set according to the mechanical interface specifications of the LCD panel. If an STN or DSTN panel is selected, display control is performed using a 24-bit space-modulation FRC consisting of the 8-bit R, G, and B included in the LCDC, regardless of the color and gradation settings. Accordingly, the color and gradation specified by DSPCOLOR is selected from 16 million colors in an STN or DSTN panel. If a palette is used, the color specified in the palette is displayed. 000000: STN monochrome 4-bit data bus module 000001: STN monochrome 8-bit data bus module 001000: STN color 4-bit data bus module 001001: STN color 8-bit data bus module 001010: STN color 12-bit data bus module 001011: STN color 16-bit data bus module 010001: DSTN monochrome 8-bit data bus module 010011: DSTN monochrome 16-bit data bus module 011001: DSTN color 8-bit data bus module 011010: DSTN color 12-bit data bus module 011011: DSTN color 16-bit data bus module 101011: TFT color 16-bit data bus module Settings other than above: Setting prohibited Rev. 3.00 Sep. 28, 2009 Page 1241 of 1650 REJ09B0313-0300 Section 24 LCD Controller (LCDC) 24.3.3 LCDC Data Format Register (LDDFR) LDDFR sets the bit alignment for pixel data in one byte and selects the data type and number of colors used for display so as to match the display driver software specifications.

Write 0 to the lower nine bits. When using the hardware rotation function, set the LDSARU value so that the upper-left address of the image is aligned with the 512-byte boundary. 2. When the hardware rotation function is used (ROT = 1), set the upper-left address of the image which can be calculated from the display image size in this register. The equation below shows how to calculate the LDSARU value when the image size is 240 x 320 and LDLAOR = 256. The LDSARU value is obtained not from the panel size but from the memory size of the image to be displayed. Note that LDLAOR must be a binary exponential at least as large as the horizontal width of the image. Calculate backwards using the LDSARU value (LDSARU - 256 (LDLAOR value) x (320 - 1)) to ensure that the upper-left address of the image is aligned with the 512-byte boundary.

Because the LCDC handles these values as 16-byte data, the values written to the lower four bits of the register are always treated as 0. The lower four bits of the register are always read as 0. The initial values (x resolution = 640) will continuously and accurately place the VGA (640 x 480 dots) display data without skipping an address between lines. For details, see tables 24.4 and 24.5. A binary exponential at least as large as the horizontal width of the image is recommended for the LDLAOR value, taking into consideration the software operation speed. When the hardware rotation function is used, the LDLAOR value should be a binary exponential (in this example, 256) at least as large as the horizontal width of the image (after rotation, it becomes 240 in a 240 x 320 panel) instead of the horizontal width of the LCD panel (320 in a 320 x 240 panel).

Section 24 LCD Controller (LCDC) 24.4 Operation 24.4.1 LCD Module Sizes which Can Be Displayed in this LCDC This LCDC is capable of controlling displays with up to 1024 x 1024 dots and 16 bpp (bits per pixel). The image data for display is stored in VRAM, which is shared with the CPU. This LCDC should read the data from VRAM before display. This LSI has a maximum 32-burst memory read operation and a 2.4-kbyte line buffer, so although a complete breakdown of the display is unlikely, there may be some problems with the display depending on the combination. As a rough standard, the bus occupation ratio shown below should not exceed 40%. Overhead coefficient x Total number of display pixels ((HDCN + 1) x 8 x (VDLN + 1)) x Frame rate (Hz) x Number of colors (bpp) Bus occupation ratio (%) = x 100 CKIO (Hz) x Bus width (bit) The overhead coefficient becomes 1.375 when the CL2 SDRAM is connected to a 32-bit data bus and 1.188 when connected to a 16-bit data bus.

Only the numbers of colors for each resolution are supported as shown in tables 24.4 and 24.5. The size of the SDRAM (the number of column address bits) and its burst length are limited to read the SDRAM continuously. The number of colors for display, SDRAM column addresses, and LCDC burst length are shown tables 24.4 and 24.5. A monochromatic LCD module is necessary for the display of images in the above monochromatic formats. A color LCD module is necessary for the display of images in the above color formats.

The color palette thus allows the simultaneous display of 256 colors chosen from among 16-M colors. The procedure below may be used to set up color palettes at any time. 1. The PALEN bit in the LDPALCR is 0 (initial value); normal display operation 2. Access LDPALCR and set the PALEN bit to 1; enter color-palette setting mode after three cycles of peripheral clock. 3. Access LDPALCR and confirm that the PALS bit is 1. 4. Access LDPR00 to LDPRFF and write the required values to the PALD00 to PALDFF bits. 5. Access LDPALCR and clear the PALEN bit to 0; return to normal display mode after a cycle of peripheral clock. A 0 is output on the LCDC display data output (LCD_DATA) while the PALS bit in LDPALCR is set to 1. 31 Color 23 15 7 0 R7 R6 R5 R4 R3 R2 R1 R0 G7 G6 G5 G4 G3 G2 G1 G0 B7 B6 B5 B4 B3 B2 B1 B0 Monochrome M7 M6 M5 M4 M3 M2 M1 M0 Figure 24.3 Color-Palette Data Format PALDnn color and gradation data should be set as above. For a color display, PALDnn[23:16], PALDnn[15:8], and PALDnn[7:0] respectively hold the R, G, and B data. Although the bits PALDnn[18:16], PALDnn[9:8], and PALDnn[2:0] exist, no memory is associated with these bits. PALDnn[18:16], PALDnn[9:8], and PALDnn[2:0] are thus not available for storing palette data. The numbers of valid bits are thus R: 5, G: 6, and B: 5. A 24bit (R: 8 bits, G: 8 bits, and B: 8 bits) data should, however, be written to the palette-data registers. When the values for PALDnn[23:19], PALDnn[15:10], or PALDnn[7:3] are not 0, 1 or 0 should be written to PALDnn[18:16], PALDnn[9:8], or PALDnn[2:0], respectively. When the values of PALDnn[23:19], PALDnn[15:10], or PALDnn[7:3] are 0, 0s should be written to PALDnn[18:16], PALDnn[9:8], or PALDnn[2:0], respectively. Then 24 bits are extended. Grayscale data for a monochromatic display should be set in PALDnn[7:3]. PALDnn[23:8] are all "don't care". When the value in PALDnn[7:3] is not 0, 1s should be written to PALDnn[2:0]. When the value in PALDnn[7:3] is 0, 0s should be written to PALDnn[2:0]. Then 8 bits are extended.

Rev. 3.00 Sep. 28, 2009 Page 1280 of 1650 REJ09B0313-0300 Section 24 LCD Controller (LCDC) 24.4.5 Setting the Display Resolution The display resolution is set up in LDHCNR, LDHSYNR, LDVDLNR, LDVTLNR, and LDVSYNR. The LCD current-alternating period for an STN or DSTN display is set by using the LDACLNR. The initial values in these registers are typical settings for VGA (640 x 480 dots) on an STN or DSTN display. The clock to be used is set with the LDICKR. The LCD module frame rate is determined by the display interval + retrace line interval (non-display interval) for one screen set in a size related register and the frequency of the clock used. This LCDC has a Vsync interrupt function so that it is possible to issue an interrupt at the beginning of each vertical retrace line period (to be exact, at the beginning of the line after the last line of the display). This function is set up by using the LDINTR. 24.4.6 Power Management Registers An LCD module normally requires a specific sequence for processing to do with the cutoff of the input power supply. Settings in LDPMMR, LDPSPR, and LDCNTR, in conjunction with the LCD power-supply control pins (LCD_VCPWC, LCD_VEPWC, and LCD_DON), are used to provide processing of power-supply control sequences that suits the requirements of the LCD module. Figures 24.4 to 24.7 are summary timing charts for power-supply control sequences and table 24.6 is a summary of available power-supply control sequence periods.

H'0 to H'E settings select from 1 to15 frames. The setting H'F selects 0 frames. Actual sequence periods depend on the register values and the frame frequency of the display. The following table gives power-supply control-sequence periods for display frame frequencies used by typical LCD modules. * When ONB is set to H'6 and display's frame frequency is 120 Hz The display's frame frequency is 120 Hz. 1 frame period is thus 8.33 (ms) = 1/120 (sec). The power-supply input sequence period is 7 frames because ONB setting is subtracted by 1. As a result, the sequence period is 58.33 (ms) = 8.33 (ms) x 7.

Some of the supply voltages described may not be necessary, because some modules internally generate the power supply required for highvoltage systems from the logic-level power-supply voltage. * Notes on display-off mode (LCDC stopped) If LCD module power-supply control-sequence processing is in use by the LCDC or the supply of power is cut off while the LCDC is in its display-on mode, normal operation is not guaranteed. In the worst case, the connected LCD module may be damaged. 24.4.7 Operation for Hardware Rotation Operation in hardware-rotation mode is described below. Hardware-rotation mode can be thought of as using a landscape-format LCD panel instead of a portrait-format LCD panel by placing the landscape-format LCD panel as if it were a portrait-format panel. Whether the panel is intended for use in landscape or portrait format is thus no problem. The panel must, however, be within 320 pixels wide. When making settings for hardware rotation, the following five differences from the setting for no hardware rotation must be noted. (The following example is for a display at 8 bpp. At 16 bpp, the amount of memory per dot will be doubled. The image size and register values used for rotation will thus be different.) Rev. 3.00 Sep. 28, 2009 Page 1286 of 1650 REJ09B0313-0300 Section 24 LCD Controller (LCDC) 1. The image data must be prepared for display in the rotated panel. (If 240 x 320 pixels will be required after rotation, 240 x 320 pixel image data must be prepared.) 2. The register settings for the address of the image data must be changed (LDSARU and LDLAOR). 3. LDLAOR should be power of 2 (when the horizontal width after rotation is 240 pixels, LDLAOR should be set to 256). 4. Graphics software should be set up for the number 3 setting. 5. LDSARU should be changed to represent the address of the data for the lower-left pixel of the image rather than of the data for the upper-left pixel of the image. 1) Normal mode LDSARU (start point) LDSARU + LDLAOR - 1 Picture image Picture image Scanning starts from LDSARU. Scanning is done from small address to large address of X coordination. LDSARU + LDLAOR x LDVDLNR - 1(end point) Start point LCD panel Picture image End point Figure 24.8 Operation for Hardware Rotation (Normal Mode) For example, the registers have been set up for the display of image data in landscape format (320 x 240), which starts from LDSARU = 0x0c001000, on a 320 x 240 LCD panel. The graphics driver software is complete. Some changes are required to apply hardware rotation and use the panel as a 240 x 320 display. If LDLAOR is 512, the graphics driver software uses this power of 2 as the offset for the calculation of the addresses of Y coordinates in the image data. Before setting ROT to 1, the image data must be redrawn to suit the 240 x 320 LCD panel. LDLAOR will then Rev. 3.00 Sep. 28, 2009 Page 1287 of 1650 REJ09B0313-0300 Section 24 LCD Controller (LCDC) be 256 because the size has changed and the graphics driver software must be altered accordingly. The point that corresponds to LDSARU moves from the upper left to the lower left of the display, so LDSARU should be changed to 0x0c001000 + 256 * 319. Note: Hardware rotation allows the use of an LCD panel that has been rotated by 90 degrees. The settings in relation to the LCD panel should match the settings for the LCD panel before rotation. Rotation is possible regardless of the drawing processing carried out by the graphics driver software. However, the sizes in the image data and address offset values which are managed by the graphics driver software must be altered. 2) Rotation mode LDSARU - LDLAOR x (HDCN x 8 - 2) - 1(end point) Picture image Scanning starts from LDSARU. Scanning is done from large address to small address of Y coordination.

In 8-bit access, the register can be read but cannot be written to. 2. The initial value depends on the operating mode of the LSI. 25.2.1 Port B I/O Register L (PBIORL) PBIORL is a 16-bit readable/writable register that is used to set the pins on port B as inputs or outputs. The PB11IOR to PB8IOR bits correspond to the PB11/CTx1 to PB8/CRx0/ CRx0/CRx1 pins, respectively. PBIORL is enabled when the port B pins are functioning as general-purpose input/output (PB11 to PB18). In other states, they are disabled. If a bit in PBIORL is set to 1, the corresponding pin on port B functions as output. If it is cleared to 0, the corresponding pin functions as input. Bits 15 to 12 and bits 7 to 0 in PBIORL are reserved. These bits are always read as 0. The write value should always be 0.

The PC14IOR to PC0IOR bits correspond to the PC14/WAIT to PC0/A0/CS7 pins, respectively. PCIORL is enabled when the port C pins are functioning as general-purpose inputs/outputs (PC14 to PC0). In other states, PCIORL is disabled. If a bit in PCIORL is set to 1, the corresponding pin on port C functions as an output pin. If it is cleared to 0, the corresponding pin functions as an input pin. Bit 15 of PCIORL is reserved. This bit is always read as 0. The write value should always be 0.

The PE15IOR to PE0IOR bits correspond to the PE15/IOIS16/RTS3 to PE0/BS/RxD0/ADTRG pins respectively. PEIORL is enabled when the port E pins are functioning as general-purpose inputs/outputs (PE15 to PE0). In other states, it is disabled. If a bit in PEIORL 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.

However, note that the voltage retained in the high-impedance state may fluctuate due to noise. Rev. 3.00 Sep. 28, 2009 Page 1364 of 1650 REJ09B0313-0300 Section 26 I/O Ports Section 26 I/O Ports This LSI has six ports: A to F. All port pins are multiplexed with other pin functions. The functions of the multiplex pins are selected by means of the pin function controller (PFC). Each port is provided with data registers for storing the pin data and port registers for reading the states of the pins. 26.1 Features 1. Total port number: 99 ports (I/O: 82 ports, Input: 16 ports, Output: 1 ports) Port A: (Input: 8 ports) Port B: (I/O: 4 ports, Input: 8 ports, Output: 1 port) Port C: (I/O: 15 ports) Port D: (I/O: 16 ports) Port E: (I/O: 16 ports) Port F: (I/O: 31 ports) 2. The following pins in this LSI have weak keeper circuits that prevent the pins from floating into intermediate voltage levels. Port B: PB8 to PB12 Port C: PC0 and PC14 Port D: PD0 to PD15 Port E: PE0 to PE15 Port F: PF0 to PF30 The I/O pins include weak keeper circuits that fix the input level high or low when the I/O pins are not driven from outside. Generally in the CMOS products, input levels in unused input pins must be fixed by way of external pull-up or pull-down resistors. However, the I/O pins having weak keeper circuits in this LSI can eliminate these outer circuits and reduce parts number of the system. If the pull-up or pull-down resistors become necessary to fix the pin level, use the resistor of 10 k or smaller.

The PA7DR to PA0DR bits correspond to the PA7/AN7/DA1 to PA0/AN0 pins, respectively. The general input function of the PA7 to PA0 pins is enabled only when the A/D and D/A converters are halted. Writing to these bits is ignored, and therefore does not affect the pin state. If these bits are read, the pin state, not the bit value, is directly returned. Note that, however, this register should not be read during operation of the A/D or D/A converter. Table 26.2 summarizes PADRL read/write operation.

The PF30DR to PF0DR bits correspond to the PF30/AUDIO_CLK to PF0/TCLKA/LCD_DATA0/SSCK0 pins, respectively. When a pin function is general output, if a value is written to PEDRH or PEDRL, that value is output directly from the pin, and if PEDRH or PEDRL is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PEDRH or PEDRL is read, the pin state, not the register value, is returned directly. If a value is written to PEDRH or PEDRL, although that value is written into PEDRH or PEDRL, it does not affect the pin state. Table 26.12 summarizes PFDRH/PFDRL read/write operation.

These memory units can be used to store instructions or data. On-chip high-speed RAM operation and write access to the RAM can be enabled or disabled through the RAM enable bits and RAM write enable bits. Retention or non-retention of data by the on-chip RAM for data retention in deep standby mode is selectable on a per-page basis. 27.1 Features * Memory map The on-chip RAM is located in the address spaces shown in tables 27.1 and 27.2.

(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 DMAC. The on-chip RAM for data retention has one read/write port and is connected to the peripheral bus. * Priority When the same page of the on-chip high-speed RAM is accessed from different buses simultaneously, the access is processed according to the priority. The priority is ID bus > M bus > F bus. * Number of access cycles On-chip high-speed RAM: the number of cycles for access to read or write from buses F and I is one cycle of I. Number of cycles for access from the ID bus depend on the ratio of the internal clock (I) to the bus clock (B). Table 27.3 indicates number of cycles for access from the ID bus. Table 27.3 Number of Cycles for Access to On-Chip High-Speed RAM from the ID Bus Read/Write Ratio of I and B Number of Access (B) Cycles Read 1:1 3 1:2 2 1:3 2 1:4 2 1:6 1 1:8 1 1:1 2 1:2 2 1:3 2 1:4 2 1:6 1 1:8 1 Write Note: For the settable ratios of I to B, see section 5, Clock Pulse Generator. On-chip data retention RAM: The number of cycles required to read or write from the IC bus or ID bus ranges from 1 B + 2 P (minimum) to 3 P (maximum).

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. 27.2.2 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 27.1 Examples of Read/Write Rev. 3.00 Sep. 28, 2009 Page 1395 of 1650 REJ09B0313-0300 Section 27 On-Chip RAM 27.2.3 Areas where Placing Instructions Is Prohibited Do not place instructions at the addresses within 16 bytes of the last address in the on-chip RAM for data retention, i.e., at addresses H'FFFFBFF0 to H'FFFFBFFF. If an instruction is placed at any of these prohibited locations, an overrun may cause the CPU to fetch from the address space (H'FFFFC000 and subsequent addresses) for the on-chip peripheral modules, and this will lead to an address error.

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. 28.1 Features 28.1.1 Power-Down Modes This LSI has the following power-down modes and function: 1. Sleep mode 2. Software standby mode 3.

The pin state is retained or set to high impedance. For details, see appendix A, Pin States. 2. RTC operates when the START bit in the RCR2 register is set to 1. For details, see section 14, Realtime Clock (RTC). When deep standby mode is canceled by a poweron reset, the running state cannot be retained. Make the initial setting for the realtime clock again. 3. Setting the bits RAMKP3 to RAMKP0 in the RAMKP register to 1 enables to retain the data in the corresponding area on the on-chip RAM during the transition to deep standby. However, the stored contents are initialized when deep standby mode is canceled by a power-on reset. 4. Deep standby mode can be canceled by an interrupt (NMI or IRQ) or a reset (manual reset or power-on reset). However, when deep standby mode is canceled by the NMI interrupt or IRQ interrupt, power-on reset exception handling is executed instead of interrupt exception handling. The power-on reset exception handling is executed also in the cancellation of deep standby mode by manual reset. 5. The stored contents are initialized when software standby mode is canceled by a power-on reset. 6. The stored contents can be retained even when software standby mode is canceled by a power-on reset by disabling access to the on-chip RAM (high-speed) by means of the RAME bits in the SYSCR1 register or the RAMWE bits in the SYSCR2 register.

Only byte access is valid. When an RAME bit is set to 1, the corresponding on-chip RAM (high-speed) area is enabled. When an RAME bit is cleared to 0, the corresponding on-chip RAM (high-speed) area cannot be accessed. In this case, an undefined value is returned when reading data or fetching an instruction from the on-chip RAM (high-speed), and writing to the on-chip RAM (high-speed) is ignored. The initial value of an RAME bit is 1. Note that when clearing the RAME bit to 0 to disable the on-chip RAM (high-speed), be sure to execute an instruction to read from or write to the same arbitrary address in each page before setting the RAME bit. If such an instruction is not executed, the data last written to each page may not be written to the on-chip RAM (high-speed). Furthermore, an instruction to access the on-chip RAM (high-speed) should not be located immediately after the instruction to write to SYSCR1. If an on-chip RAM (high-speed) access instruction is set, normal access is not guaranteed. When setting the RAME bit to 1 to enable the on-chip RAM (high-speed), an instruction to read SYSCR1 should be located immediately after the instruction to write to SYSCR1.

(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 in clock modes 0, 1 and 3. 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 30.3, Register States in Each Operating Mode. The CPU takes one cycle to finish writing to STBCR, 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 STBCR to have the values written to STBCR 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 WDT's timer control register (WTCSR) to 0 to stop the WDT. 2. Set the WDT's timer counter (WTCNT) 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 STBCR to 1 and 0 respectively, read STBCR. Then, execute a SLEEP instruction. Rev. 3.00 Sep. 28, 2009 Page 1424 of 1650 REJ09B0313-0300 Section 28 Power-Down Modes (2) Canceling Software Standby Mode Software standby mode is canceled by interrupts (NMI or IRQ) or a reset (manual reset or poweron reset). In clock modes 0, 1 and 3, 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 interrupt control register 0 (ICR0) of the interrupt controller (INTC)) 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 (INTC)) is detected, clock oscillation is started. This clock pulse is supplied only to the oscillation settling counter (WDT) 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 WDT before the transition to software standby mode, the WDT 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 IRRQ) 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 WDT 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. When software standby mode is canceled by the falling edge of the NMI pin, the NMI pin should be high when the CPU enters software standby mode (when the clock pulse stops) and should be low when software standby mode is canceled (when the clock is initiated after oscillation settling). When software standby mode is canceled by the rising edge of the NMI pin, the NMI pin should be low when the CPU enters software standby mode (when the clock pulse stops) and should be high when software standby mode is canceled (when the clock is initiated after oscillation settling). (The same applies to the IRQ pin.) * 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. When the MRES pin is driven low, software standby mode is canceled and the LSI enters the manual reset state. After that, if the MRES pin is driven high, the manual reset exception handling is started. Rev. 3.00 Sep. 28, 2009 Page 1425 of 1650 REJ09B0313-0300 Section 28 Power-Down Modes Keep the RES or MRES pin low until the clock oscillation settles. The internal clock will continue to be output to the CKIO pin in clock modes 0, 1 and 3. (3) Note on Release from Software Standby Mode Release from software standby mode is triggered by interrupts (NMI and IRQ) or resets (manual reset and power-on reset). If, however, a SLEEP instruction and an interrupt other than NMI and IRQ are generated at the same time, cancellation of software standby mode may occur 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. Rev. 3.00 Sep. 28, 2009 Page 1426 of 1650 REJ09B0313-0300 Section 28 Power-Down Modes 28.3.3 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 28.1. 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 STBCR 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 RAM (for data retention) retaining area specified by the RRAMKP3 to RRAMKP0 bits in DSCTR and RTC. 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 DSCTR, 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 DSCTR to reflect the values written to DSCTR by the CPU in the SLEEP instruction without fail. The procedure for switching to deep standby mode is as follows. Figure 28.2 also shows its flowchart. 1. To ensure that data is actually retained in deep standby mode by the on-chip RAM (for data retention), set H'09 to DSRTR. 2. Set the RRAMKP3 to RRAMKP0 bits in DSCTR for the corresponding on-chip RAM (for data retention) area that must be retained. Transfer the programs to be retained to the specified areas of the on-chip RAM (for data retention). 3. To cancel deep standby mode by an interrupt, set to 1 the bit in DSSSR corresponding to the pin to be used for cancellation. In this case, also set the input signal detection mode (using interrupt control registers 0 and 1 (ICR0 and ICR1) of the interrupt controller (INTC)) for the pin used for cancellation. In the case of deep standby mode, only rising- or falling-edge detection is valid. (Low-level detection or both-edge detection of the IRQ signal cannot be used to cancel deep standby mode.) 4. Execute read and write of an arbitrary but the same address for each page in the retaining onchip RAM (for data retention) area. When this is not executed, data last written may not be written to the on-chip RAM (for data retention). If there is a write to the on-chip RAM (for data retention) after this time, execute this processing after the last write to the on-chip RAM (for data retention). 5. Set the STBY and DEEP bits in the STBCR register to 1. 6. Read out the DSFR register after clearing the flag in the DSFR register. Then execute the SLEEP instruction.

When canceling the mode by the interrupt NMI or IRQ, a power-on reset exception handling is executed instead of an interrupt exception handling. When canceling the mode by manual reset, the same handling is executed. Figure 28.3 shows the flowchart of canceling deep standby mode.

After the oscillation settling time has elapsed, deep standby mode is cancelled and the power-on reset exception handling is executed. 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 deep standby mode is not canceled. The clock output phase of the CKIO pin may be unstable immediately after detecting an interrupt and until deep standby mode is canceled. When deep standby mode is canceled by the falling edge of the NMI pin, the NMI pin should be high when the CPU enters deep standby mode (when the clock pulse stops) and should be low when deep standby mode is canceled (when the clock is initiated after oscillation settling). When deep standby mode is canceled by the rising edge of the NMI pin, the NMI pin should be low when the CPU enters deep standby mode (when the clock pulse stops) and should be high when deep standby mode is canceled (when the clock is initiated after oscillation settling). (The same applies to the IRQ pin.) In addition, the pin levels of the NMI pin and all interrupt pins (IRQ) selected to cancel deep standby mode (by settings in the deep standby mode cancelation source select register) should be as follows during the transition to deep standby mode, regardless of whether or not those pins are actually used to cancel deep standby mode: Pins set to cancel deep standby mode at their rising edge should be low during the transition. Pins set to cancel deep standby mode at their falling edge should be high during the transition. * Canceling with a reset When the RES pin is driven low, this LSI leaves deep standby mode and enters the power-on reset state. After this, driving the RES pin high initiates power-on reset exception handling. Driving the RES pin low in clock mode 0, 1, or 3 starts output of the internal clock from the CKIO pin. Driving the MRES pin low cancels deep standby mode and causes a transition to the power-on reset state. After this, driving the MRES pin high initiates power-on reset exception handling. In clock mode 0, 1, or 3, output of the internal clock from the CKIO pin also starts by driving the MRES pin high. Keep the RES or MRES pin low until the clock oscillation has settled.

By setting the CS0KEEPE bit, the states of the external bus control pins can be retained even after cancellation of deep standby mode. Table 28.3 shows the pin states after cancellation of deep standby mode according to the setting of each bit. Table 28.4 lists the external bus control pins. Table 28.3 Pin States after Cancellation of Deep Standby Mode and System Activation Method by the DSCTR2 Settings CS0KEEPE Bit RAMBOOT Bit Activation Method Pin States After Cancellation of Deep Standby Mode 0 0 External bus The states of the external bus control pins are not retained.

Pins retain the state immediately before the transition to deep standby mode. However, in system activation through the external bus, the retention of the states of the external bus 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 from the same bit. In system activation from the on-chip RAM (for data retention), after cancellation of deep standby mode, both the external bus control pins and other pins continues to retain the pin states until writing 0 to the IOKEEP bit in DSFR 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 CPG, INTC, BSC, I/O ports, PFC, 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 After deep standby mode is specified, interrupts other than those set as cancel sources in the deep standby cancel source select register are masked. If multiple interrupts are set as cancel sources in the deep standby cancel source select register and more than one of these cancel sources are input, multiple cancel source flags are set. In addition, if a SLEEP instruction to initiate the transition to deep standby mode coincides with an NMI or IRQ interrupt, or with a manual reset, acceptance of the interrupt may cause cancellation of deep standby mode. Rev. 3.00 Sep. 28, 2009 Page 1433 of 1650 REJ09B0313-0300 Section 28 Power-Down Modes 28.3.5 (1) Module Standby Function Transition to Module Standby Function Setting the standby control register MSTP bits to 1 halts the supply of clocks to the corresponding on-chip peripheral modules. 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 30.3, 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 RTC, H-UDI, UBC, and DMAC). 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. 28.4 Usage Notes 28.4.1 Notes on Writing to Registers When writing to the registers related to power-down modes, note the following. 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. 28.4.2 Notice about Deep Standby Control Register 2 (DSCTR2) After (1) power-on reset by RES pin is released, and (2) the LSI transits to deep standby mode in case that bit 7 (CS0KEEPE) and bit 6 (RAMBOOT) of deep standby control register 2 (DSCTR2) are set to "1", these bits become unable to be written as "0" since then. To write these as "0", it is necessary to assert RES pin to low. Rev. 3.00 Sep. 28, 2009 Page 1434 of 1650 REJ09B0313-0300 Section 28 Power-Down Modes 28.4.3 Notice about Power-On Reset Exception Handling * After (1) power-on reset by RES pin is released, (2) the LSI transit to deep standby mode in case that bit 6 (RAMBOOT) of deep standby control register 2 (DSCTR2) is set to "1", (3) the deep standby mode is cancelled, and (4) power-on reset by WDT or H-UDI reset is occurred before power-on reset by RES pin is executed again, then the behavior of the power-on reset exception handling is as table 28.5. So if applicable as above case, PC and SP are necessary to be retained in the area of on-chip RAM for data retention. Table 28.5 Power-On Reset Exception Handling Address where the program counter (PC) is fetched Address where the stack pointer (SP) is fetched H'FFFF8000 H'FFFF8004 * After (1) power-on reset by RES pin is released, (2) the LSI transit to deep standby mode, and (3) the deep standby mode is cancelled, if there is a possibility that power-on reset by WDT or H-UDI reset is occurred before power-on reset by RES pin is executed again, the settings of WDT or H-UDI should be done in the condition that bit 15 (IOKEEP) and bits 9~0 of deep standby cancel source flag register (DSFR) are all cleared after canceling deep standby mode (if some bits are 1, please write these as "0"). If (1) the setting of WDT or H-UDI is done in the condition that IOKEEP bit is not 0, and (2) power-on reset by WDT or H-UDI reset is occurred before power-on reset by RES pin is executed again, the pin status of the pins, whose pin status are retained in deep standby mode and which are not in table 28.4, are kept retained. Additionally, in the case that bit 7 (CS0KEEPE) of deep standby control register 2 (DSCTR2) are set to "1", the pin status of the pins in table 28.4 are also keep retained. If (1) the settings of WDT or H-UDI is done in the condition that bits 9~0 are not all 0, and (2) power-on reset by WDT or H-UDI reset is occurred before power-on reset by RES pin is executed again, the internal information about the deep standby canceling source is not cleared, and deep standby mode are cancelled by the wrong canceling source when the LSI attempt to transit to deep standby mode since then.

In this state, the CPU does not start up. When TRST is driven high, H-UDI operation is enabled, but the CPU does not start up. The reset hold state is cancelled by a power-on reset. 29.4.3 TDO Output Timing The initial value of the TDO change timing is to perform data output from the TDO pin on the TCK falling edge. However, setting a TDO change timing switch command in SDIR via the HUDI pin and passing the Update-IR state synchronizes the TDO change timing to the TCK rising edge. Hereafter, to synchronize the change timing of TD0 to the falling edge of TCK, the TRST pin must be simultaneously asserted with the power-on reset. In a 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 negate of the RES pin, the TD0 change timing switch command is cleared, resulting the TD0 change timing synchronized with the falling edge of TCK. To prevent this, make sure to put a period of 20 times of tcyc or longer between the signal change timing of the RES and TRST pins.

An H-UDI reset is of the same kind as a power-on reset. An H-UDI reset is released by setting an H-UDI reset negate command. The required time between the H-UDI reset assert command and H-UDI reset negate command is the same as time for keeping the RES pin low to apply a power-on reset. SDIR H-UDI reset assert H-UDI reset negate Chip internal reset Fetch the initial values of PC and SR from the exception handling vector table CPU state Figure 29.4 H-UDI Reset 29.4.5 H-UDI Interrupt The H-UDI interrupt function generates an interrupt by setting a command from the H-UDI in SDIR. An H-UDI 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. H-UDI interrupts are accepted in sleep mode, but not in software standby mode. Rev. 3.00 Sep. 28, 2009 Page 1443 of 1650 REJ09B0313-0300 Section 29 User Debugging Interface (H-UDI) 29.5 Usage Notes 1. An H-UDI command, once set, will not be modified as long as another command is not set again from the H-UDI. 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 H-UDI module standby state, all of the functions in the H-UDI cannot be used. To retain the TAP status before and after standby mode, keep TCK high before entering standby mode. 3. Regardless of whether or not the H-UDI is in use, be sure to keep the TRST pin low to initialize the H-UDI when power is supplied or when assertion of the RES signal cancels deep standby mode. 4. When the TDO change timing switch command is set and the TRST pin is asserted immediately after and the RES pin is negated, the TDO change timing switch command may be cleared. To prevent this, make sure to insert an interval of 20 tcyc or more between the signal changes of the RES and TRST pins when the TDO change timing switch command is set. Make sure to put 20 tcyc or more between the signal change timing of the RES and TRST pins. For details, see section 29.4.3, TDO Output Timing. 5. When starting the TAP controller after the negation of the TRST pin, make sure to allow 200 ns or more after the negation. Rev. 3.00 Sep. 28, 2009 Page 1444 of 1650 REJ09B0313-0300 Section 30 List of Registers Section 30 List of Registers This section gives information on the on-chip I/O registers of this LSI in the following structures. 1. 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. 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. 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. 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 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.

An indefinite period of time appears, from the time that power is turned on to the time that both of the 1.2-V power supply and the 3.3-V power supply rise to the Min. voltage (1.1 V for 1.2-V power supply and 3.0 V for 3.3-V power supply), or from the time that either of the 1.2-V power supply or the 3.3-V power supply is turned off and passes the Min. voltage (1.1 V for 1.2-V power supply and 3.0 V for 3.3-V power supply) to the time that both of the 1.2V power supply and the 3.3-V power supply fall to GND. During these periods, states of output pins and in-out pins and internal states become undefined. So it should be as short as possible. Also design the system so that these undefined states do not cause an overall malfunction.

The pin states after a power-on reset by the H-UDI reset assert command or WDT overflow are the same as the initial pin states at normal operation (see section 25, Pin Function Controller (PFC)). Rev. 3.00 Sep. 28, 2009 Page 1611 of 1650 REJ09B0313-0300 Appendix 2. After the chip has shifted to the power-on reset state from deep standby mode by the input on any of pins NMI, MRES, and IRQ7 to IRQ0, the pins retain the state until the IOKEEP bit in the deep standby cancel source flag register (DSFR) is cleared (see section 28, Power-Down Modes). 3. The week keeper circuits included in the I/O pins are turned off. 4. When pins for the connection with a crystal resonator are not used, the input pins (EXTAL, RTC_X1, AUDIO_X1, and USB_X1) must be fixed (pulled up, pulled down, connected to power supply, or connected to ground) and the output pins (XTAL, RTC_X2, AUDIO_X2, and USB_X2) must be open. 5. The initial pin function depends on the data bus width of area 0 (see section 25, Pin Function Controller (PFC)). 6. Depends on the setting of the CKOEN bit in the frequency control register (FRQCR) of the CPG (see section 4, Clock Pulse Generator (CPG)). 7. Depends on the setting of the HIZ bit in the standby control register 3 (STBCR3) (see section 28, Power-Down Modes). 8. Depends on the setting of the HIZMEM bit in the common control register (CMNCR) of the BSC (see section 9, Bus State Controller (BSC)). 9. Depends on the setting of the HIZCNT bit in the common control register (CMNCR) of the BSC (see section 9, Bus State Controller (BSC)). 10. Depends on the setting of the corresponding bit in the deep standby cancel source select register (DSSSR) (see section 28, Power-Down Modes). 11. Depends on the setting of the RTCEN bit in the RTC control register 2 (RCR2) of the RTC (see section 14, Realtime Clock (RTC)). 12. Depends on the AXTALE bit in the standby control register (STBCR) (see section 28, Power-Down Modes). 13. When the CS0KEEPE bit in the deep standby control register 2 (DSCTR2) is 1, this pin retains the state of deep standby mode. When the CS0KEEPE bit is 0, this pin enters the state of a power-on reset (see section 28, Power-Down Modes). 14.

If these bits are set to 01, the CKIO pin is fixed at low during standby mode or cancellation of standby mode. Therefore, the malfunction of an external circuit caused by an unstable CKIO clock during cancellation of standby mode can be prevented. In clock operating mode 2, the CKIO pin functions as an input regardless of the value of these bits. In deep standby mode, the normal state is retained.

If DMA transfer ends because of an NMI interrupt, a DMA address error, or clearing of the DE bit or the DME bit in DMAOR before the transfer count reaches half of the initial DMATCR value, the HE bit is not set to 1. If DMA transfer ends due to an NMI interrupt, a DMA address error, or clearing of the DE bit or the DME bit in DMAOR after the HE bit is set to 1, the bit remains set to 1.

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.*2 Even if the DE bit is set to 1 while the TEMASK bit is 0 and this bit is 1, transfer is not enabled. 0: During the DMA transfer or DMA transfer has been terminated [Clearing condition] * Writing 0 after reading TE = 1*2 1: DMA transfer ends by the specified count (DMATCR = 0) 411 Notes added Notes: 1. Only 0 can be written to clear the flag after 1 is read. 2. If the flag is read at the same timing it is set to 1, the read data will be 0, but the internal state may be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be cleared to 0 because the internal state is the same as when writing 0 after reading 1.

This bit can only be cleared by writing 0 after reading 1.*2 When the NMI is input, the DMA transfer in progress can be done in one transfer unit. Even if the NMI interrupt is input while the DMAC is not in operation, the NMIF bit is set to 1. 0: No NMI interrupt 1: NMI interrupt occurred [Clearing condition] * 416 Writing 0 after reading NMIF = 1*2 Notes added Notes: 1. Only 0 can be written to clear the flag after 1 is read. 2. If the flag is read at the same timing it is set to 1, the read data will be 0, but the internal state may be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be cleared to 0 because the internal state is the same as when writing 0 after reading 1.

Even though the value of DMATCR_n is rewritten by reload operation, half end flag is set based on the value set when transfer is started. Because of this, there may be errors where (a) the set timing of the half end flag is not correct, or (b) the half end flag can not be set, may be generated. When executing DMA transfer by reload function under the condition that different values are set to RDMATCR_n from DMATCR_n, do not use half end flag or half end interrupt.

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 IRRQ) 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. 1431 Description amended * Canceling by an interrupt When the falling edge or rising edge of the NMI pin (selected by the NMI edge select bit (NMIE) in interrupt control register 0 (ICR0) of the interrupt controller (INTC)) or the falling edge or rising edge of an IRQ pin (IRQ7 to IRQ0 assigned to PE11 to PE4) (selected by the IRQn sense select bits (IRQn1S and IRQn0S) in interrupt control register 1 (ICR1) of the interrupt controller (INTC)) is detected, clock oscillation is started after the wait time for the oscillation settling time. After the oscillation settling time has elapsed, deep standby mode is cancelled and the power-on reset exception handling is executed. 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 deep standby mode is not canceled. ... (The same applies to the IRQ pin.) In addition, the pin levels of the NMI pin and all interrupt pins (IRQ) selected to cancel deep standby mode (by settings in the deep standby mode cancelation source select register) should be as follows during the transition to deep standby mode, regardless of whether or not those pins are actually used to cancel deep standby mode: Pins set to cancel deep standby mode at their rising edge should be low during the transition. Pins set to cancel deep standby mode at their falling edge should be high during the transition. Rev. 3.00 Sep. 28, 2009 Page 1634 of 1650 REJ09B0313-0300 Item Page Revision (See Manual for Details) 28.3.4 Deep Standby Mode 1433 Description amended ... Pins retain the state immediately before the transition to deep standby mode. However, in system activation through the external bus, the retention of the states of the external bus 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 from the same bit. In system activation from the on-chip RAM (for data retention), after cancellation of deep standby mode, both the external bus control pins and other pins continues to retain the pin states until writing 0 to the IOKEEP bit in DSFR from the same bit. (3) Operation after Canceling Deep Standby Mode 28.4.3 Notice about Power-On Reset Exception Handling 1435 30.2 Register Bits 1496 Description amended * After (1) power-on reset by RES pin is released, (2) the LSI transit to deep standby mode, and (3) the deep standby mode is cancelled, if there is a possibility that power-on reset by WDT or H-UDI reset is occurred before power-on reset by RES pin is executed again, the settings of WDT or H-UDI should be done in the condition that bit 15 (IOKEEP) and bits 9~0 of deep standby cancel source flag register (DSFR) are all cleared after canceling deep standby mode (if some bits are 1, please write these as "0" ).
