Chapter 1 Introduction Freescale Semiconductor, Inc... The DSP56311 Evaluation Module (EVM) is used to demonstrate the abilities of the DSP56311 and provide a hardware tool allowing the development of applications that use the DSP56311. The DSP56311EVM is an evaluation module board that includes a DSP56311 part, peripheral expansion connectors, external memory, and a voice codec. The peripheral expansion connectors are used for signal monitoring and user-feature expandability. The DSP56311EVM is designed for the following purposes: * To allow new users to become familiar with the features of the 56300 architecture. The tools and examples provided with the DSP56311EVM facilitate evaluation of the feature set and the benefits of the family. * To serve as a platform for real-time software development. The tool suite enables the user to develop and simulate routines, download the software to on-chip or on-board RAM, and then run and debug the software using a debugger via the JTAG/OnCETM port. The breakpoint features of the OnCE port enable the user to easily specify break conditions and to execute user-developed software at full speed, until the break conditions are satisfied. The ability to examine and modify all user-accessible registers, memory, and peripherals through the OnCE port greatly facilitates the task of the developer. * To serve as a platform for hardware development. The hardware platform enables the user to connect external hardware peripherals. The on-board peripherals can be disabled, providing the user with the ability to reassign any and all of the DSP's peripherals. The OnCE port's unobtrusive design means that all of the memory on the board and on the DSP chip is available to the user. 1.1 DSP56311EVM Architecture The DSP56311EVM is used to facilitate the evaluation of various features of the DSP56311 part. The DSP56311EVM can be used to develop real-time software and hardware products based on the DSP56311. The DSP56311EVM provides the features necessary for a user to write and debug software, to demonstrate the functionality of that software, and to be able to interface with the customer's application specific device(s). The DSP56311EVM is flexible enough to allow the user to fully exploit the features of the DSP56311. See Figure 1-1.

DSP56311EVM Functional Block Diagram 2.3.1 FSRAM The DSP56311EVM uses one bank of 64K x 24-bit fast static RAM (GS71024T-8, labelled U2) for memory expansion. The GS71024T-8 uses a single 3.3 V power supply and has an access time of 8 ns. The following sections detail the operation of the FSRAM.

DSP56311EVM Technical Summary 2.3.1.1 FSRAM Connections The basic connection for the FSRAM is shown in Figure 2-3. DSP56311 FSRAM A0-A14 A0-A14 D0-D23 IO0-IO23 CE1 AA0 RD OE WR WE A15 1 A15 2 Freescale Semiconductor, Inc... AA3 3 AA2066 J3 Figure 2-3. FSRAM Connections to the DSP56311 The data input/output pins IO0-IO23 for the FSRAM are connected to the DSP56311 D0-D23 pins. The FSRAM write enable (WE) and output enable (OE) lines are connected to the DSP56311 write enable (WR) and read enable (RD) lines, respectively. The FSRAM chip enable (CE1) is generated by the DSP56311 address attribute 0 (AA0). The FSRAM activity is controlled by AA0 and the corresponding address attribute register 0 (AAR0). The FSRAM address input pins, A0-A14, are connected to the respective port A address pins of the DSP. Address bit A15 and address attribute 3 (AA3) are connected to jumper J3 pin 1 and pin 3 respectively. Pin 2 of jumper J3 is then connected to address bit A15 of the FSRAM. This allows the external FSRAM to be configured as either unified or split memory map. Table 2-1 illustrates the FSRAM configurations selectable via jumper J3. The default board configuration selects a unified memory map of 64K words. Table 2-1. J3 FSRAM Memory Configuration Options J3 Memory Map Type 1-2 Unified Memory Map (Default) 2-3 Split Memory Map When a unified memory map is selected, jumper shorting J3 pins 1 and 2, the 64K words of available external FSRAM are not partitioned into X data, Y data, and program memory. Thus, accesses to P:$1000, X:$1000, and Y:$1000 are treated as accesses to the same memory cell, and 48-bit long memory data moves are not possible to or from the external FSRAM. Selecting the split memory map partitions the 64K of available FSRAM memory into two contiguous 32K memory blocks. This configuration allows for 48-bit long memory data moves from FSRAM. Thus, access to X:$1000 and Y:$1000 could access different memory cells in the partitioned external FSRAM. The split memory map utilizes address attribute pin 3 (AA3). Activity of the DSP56311 pin AA3 is controlled by the corresponding AAR3 register. 2-4 DSP56311 Evaluation Module Hardware Reference Manual For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Memory 2.3.1.2 Example: Programming AAR0 As mentioned previously, the FSRAM activity is controlled by the DSP56311 pin AA0 and the corresponding AAR0. AAR0 controls the external access type, the memory type, and which external memory addresses access the FSRAM. Figure 2-4 shows the memory map that is attained with the AAR0 settings described in this example. NOTE: In this example, the memory switch bit in the operating mode register (OMR) is cleared, and the 16-bit compatibility bit in the status register is cleared. Freescale Semiconductor, Inc... In Figure 2-4, the FSRAM responds to the 64K of X and Y data memory addresses between $040000 and $04FFFF. However, with the unified memory map, accesses to the same external memory location are treated as accesses to the same memory cell. A priority mechanism exists among the four AAR control registers. AAR3 has the highest priority and AAR0 has the lowest. Bit 14 of the OMR, the address priority disable (APD) bit, controls which AA pins are asserted when a selection conflict occurs (that is the external address matches the address and the space that is specified in more than one AAR). If the APD bit is cleared when a selection conflict occurs, only the highest priority AA pin is asserted. If the APD bit is set when a selection conflict occurs, the lower priority AA pins are asserted in addition to the higher priority AA pin. For this example, only one AA pin must be asserted, AA0. Thus, the APD bit can be cleared. Memory Map (MS = 0, SC = 0) Program X Data Y Data $FFFFFF = Internal Memory $FF0000 $050000 Unified FSRAM $040000 $00C000 $008000 $000000 AA2067 Figure 2-4. Example Memory Map with the Unified External Memory Figure 2-5 shows the settings of AAR0 for this example. The external access type bits (BAT1 and BAT0) are set to 0 and 1, respectively, to denote FSRAM access. The address attribute polarity bit (BAAP) is cleared to define AA0 as active low. Bit 6 (BAM) of the AAR is reserved and should be written with 0 only. Packing is not needed with the FSRAM; thus, the packing enable bit (BPAC) is cleared to disable this option.

Address Attribute Register AAR0 The P, X data, and Y data space enable bits (BPEN, BXEN, and BYEN) define whether the FSRAM is activated during external P, X data, or Y data space accesses, respectively. For this example, the BXEN and BYEN bits are set, and BPEN is cleared to allow the FSRAM to respond to X and Y data memory accesses only. The number of address-bits to compare, BNC(3:0), and the address-to-compare bits, BAC(11:0), determine which external memory addresses access the FSRAM. The BNC bits define the number of upper address bits that are compared between the BAC bits and the external address to determine if the FSRAM is accessed. For this example, the FSRAM is assigned to respond to addresses between $040000 and $04FFFF. Thus, the BNC bits are set to $8 and the BAC bits are set to $040. If the eight most significant bits of the external address are 00000100, the FSRAM is accessed. 2.3.2 Flash The DSP56311EVM uses an Atmel AT29LV010A-20TC chip (U3) to provide a 128K x 8-bit CMOS flash for stand-alone operation (that is startup boot operation without accessing the DSP56311 through the JTAG/OnCE port). The AT29LV010 uses a 3.3 V power supply and has a read access time of 200 ns. 2-6 DSP56311 Evaluation Module Hardware Reference Manual For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.

DSP56311 Flash A0-A16 A0-A16 D0-D7 I/O0-I/O7 AA1 CE RD OE WR WE AA2069 Freescale Semiconductor, Inc... Figure 2-6. Flash Connections The flash address pins (A0-A16) connect the respective port A address pins on the DSP. The flash data input/output pins I/O0-I/O7 are connected to the DSP56311 D0-D7 pins. The flash write enable (WE) and output enable (OE) lines connect the DSP56311 write (WR) and read (RD) enable lines, respectively. Address attribute 1 (AA1) generates the flash chip enable, CE. 2.3.2.2 Programming for Stand-Alone Operation The DSP56311 mode pins determine the chip operating mode and startup procedure when the DSP56311 exits the reset state. The switch at SW3 resets the DSP56311 by asserting and then clearing the RESET pin of the DSP56311. The mode pins MODA, MODB, MODC, and MODD are sampled as the DSP56311 exits the reset state. The mode pins for the DSP56311EVM are controlled by jumper block J1, shown in Figure 2-1 on page 2-2 and Table 2-2. The DSP56311 boots from the flash after reset if there are jumpers connecting pins 3 and 4 and pins 5 and 6 on J1 (Mode 1: MODA and MODD are set, and MODB and MODC are cleared). The DSP56311 moves the 8-bit data from the flash into internal SRAM and then executes it. 2.4 Mode Selector Boot mode selection for the DSP56311 is made by jumper selections on header J1.

Freescale Semiconductor, Inc... 2.5 Audio Codec The DSP56311EVM analog section uses Crystal Semiconductor's CS4218-KQ for two channels of 16-bit A/D conversion and two channels of 16-bit D/A conversion. Refer to Figure 2-1 on page 2-2 for the location of the codec on the DSP56311EVM and to Figure 2-2 on page 2-3 for a functional diagram of the codec within the evaluation module. The CS4218 uses a 3.3 V digital power supply and a 5 V analog power supply. The CS4218 is driven by a 12.288 MHz signal at the codec Master Clock (CLKIN) input pin. The crystal at Y1 creates a 12.288 MHz signal which is buffered and sent to the codec. Refer to the Crystal Semiconductor's 16-Bit Stereo Audio Codec (CS4218) Data Sheet included with this kit for more information. The CS4218 is very flexible, offering selectable sampling frequencies between 8 kHz and 48 kHz. The sampling frequency is selected using jumpers on jumper block J8. Table 2-3 shows jumper positions that select the possible sampling frequencies for the DSP56311EVM. Table 2-3.

Jumper block J9 connects the ESSI1 pins of the DSP56311 to the control pins of the CS4218. Jumper block J7 connects the ESSI0 pins of the DSP56311 to the data pins of the CS4218. By removing these jumpers, the user has full access to the ESSI0 and ESSI1 pins of the DSP56311. The following sections describe the connections for the analog and digital sections of the codec. 2-8 DSP56311 Evaluation Module Hardware Reference Manual For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Audio Codec 2.5.1 Codec Analog Input/Output The DSP56311EVM contains 1/8" stereo jacks for stereo input, output, and headphones. Figure 2-7 shows the analog circuitry of the codec. CS4218 Headphone Out Line In (P3) (P5) RIN2 LIN2 LM4880 RIN1 Unused Freescale Semiconductor, Inc... LIN1 Line Out LOUT (P4) ROUT AA2070 Figure 2-7. Codec Analog Input/Output Diagram The stereo jack labelled Line In (P3) on the DSP56311EVM connects to the codec right and left input pins, RIN2 and LIN2. Standard line-level inputs are 2 VPP, but the codec requires that input levels be limited to 1 VPP. Thus, a voltage divider forms a 6 dB attenuator between P3 and the CS4218. The codec right and left channel output pins, ROUT and LOUT, provide their output analog signals through the stereo jack labelled Line Out (P4) on the DSP56311EVM. The outputs of the codec are also connected to the stereo jack labelled Headphone Out (P5) on the DSP56311EVM through National Semiconductor's LM4880 dual-audio power amplifier at U8. The headphone stereo jack permits the direct connection of stereo headphones to the DSP56311EVM. 2.5.2 Codec Digital Interface Figure 2-8 shows the digital interface to the codec.

The codec communicates with the DSP56311 through the ESSI0 for the data information and through the ESSI1 for the control information. The codec has three modes of serial operation that are selected by the serial mode select SMODE1, SMODE2, and SMODE3 pins. The SMODE pins on the DSP56311EVM are set to enable serial mode 4, which separates the audio data from the control data. The SMODE pins are also set to enable the master sub-mode with 32-bit frames, the first 16 bits being the left channel, and the second 16 bits being the right channel. The DSP56311 ESSI0 transfers the data information to and from the codec. The DSP56311 serial transmit data (STD0) pin transmits data to the codec. The DSP56311 serial receive data (SRD0) pin receives data from the codec. These two pins are connected to the codec serial port data in (SDIN) and serial port data out (SDOUT) pins, respectively. In master sub-mode, the codec serial port clock (SCLK) pin provides the serial bit rate clock for the ESSI0 interface. It is connected to the DSP56311 bidirectional serial clock (SCK0) pin. The DSP56311 serial control 0 (SC00) pin is programmed to control the codec reset signal RESET. The serial control 2 (SC02) pin is connected to the codec serial port sync (SSYNC) signal. A rising edge on SSYNC indicates that a new frame is about to start. The DSP56311 ESSI1 pins are used as general purpose I/O (GPIO) signals to transfer the control data to the codec. The control data needs to be transferred only when it changes. The DSP56311 serial control 0 (SC10) pin is programmed to control the codec multi-function pin 4 or the control data chip select pin, MF4/CCS. This pin must be low for entering control data. The serial control 1 (SC11) pin connects to the codec multi-function pin 3 or the control data clock pin, MF3/CCLK. The control data is inputted on the rising edge of CCLK. The serial control 2 (SC12) pin is connected to the codec multi-function pin 2 or the control data input pin, MF2/CDIN. This pin contains the control data for the codec. 2-10 DSP56311 Evaluation Module Hardware Reference Manual For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Command Converter 2.6 Command Converter Freescale Semiconductor, Inc... The DSP56311EVM provides an on-board command converter for use with Motorola's DSP56300 Debugger. The on-board command converter communicates with the host PC through a parallel DB25 connector and the PC's parallel printer port. The command converter receives commands from the host PC. The set of commands may include read data, write data, reset OnCE module, reset DSP56311, request JTAG interface, or release OnCE module. The command conversion is performed in software within the Motorola DSP56300 Debugger on the host PC. This software interprets the commands and sends a sequence of instructions to the DSP56311's JTAG/OnCE port. The DSP56311 may then continue to receive data or it may transmit data back to the host PC. The on-board command converter circuitry is enabled by leaving the shorting jumper J6 open. Table 2-6 shows the JTAG enable/disable options. Refer to Figure 2-1 on page 2-2 for the location of J6 on the DSP56311EVM and to Figure 2-2 on page 2-3 for a functional diagram. Figure 2-9 is a block diagram of the parallel port command converter interface. Table 2-8 shows the DB25 connector pinout. Table 2-6.

Parallel Port Interface As an alternative to the on-board command converter, the DSP56311EVM 14-pin JTAG/OnCE connector at J2 allows the user to connect an external JTAG command converter board directly to the DSP56311EVM. Jumper J6 must be shorted to enable this option. Pin 8 has been removed from J2 so that the cable cannot be connected to the DSP56311EVM incorrectly. Table 2-7 shows the JTAG/OnCE (J2) connector pinout. The JTAG cable from the external JTAG command converter is similarly keyed so that the cable cannot be connected to the DSP56311EVM incorrectly.
