Freescale Semiconductor, Inc... Chapter 1 Introduction The DSP56824Evaluation Module (EVM) is used to demonstrate the abilities of the DSP56824 and provide a hardware tool allowing the development of applications that use the DSP56824. The DSP56824EVM is an evaluation module board that includes a DSP56824 part, peripheral expansion connectors, external memory and a voice CODEC. The peripheral expansion connectors are used for signal monitoring and user feature expandability. The DSP56824EVM is designed for the following purposes: • To allow new users to become familiar with the features of the 56800 architecture. The tools and examples provided with the DSP56824EVM 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 then 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 DSP56824EVM Architecture The DSP56824EVM is used to facilitate the evaluation of various features of the DSP56824 part. The DSP56824EVM can be used to develop real-time software and hardware products based on the DSP56824.

SPI EEPROM 2.2 Program and Data Memory Freescale Semiconductor, Inc... The DSP56824EVM uses one bank of 128K × 16-bit Fast Static RAM (GSI GS72116, labelled U6) for external memory expansion, as shown in the FSRAM block diagram in Figure 2-1. This physical memory bank is split into two logical memory banks of 64K × 16-bits, one for program memory and the other for data memory. When the DSP’s program strobe PS signal line is used along with the memory chip’s A0 signal line, half of the memory chip is selected when program memory accesses are requested and the other half of the memory chip is selected when data memory access are requested.

The DSP56824 uses its internal PLL to multiply the input frequency, by 19, to achieve its 70MHz maximum operating frequency. Additionally the 3.686MHz clock source is then buffered and used by the SPI UART for its clock source, as shown in Figure 2-6. 2-8 DSP56824EVM Hardware Reference Manual For More Information On This Product, Go to: www.freescale.com Motorola Freescale Semiconductor, Inc.

These LEDs allow the programmer to monitor program execution without having to stop the program during debugging, as shown in Figure 2-7. LED1 is controlled by Port B’s General Purpose Input/Output (GPIO) signal line 8 (PB8). LED2 is controlled by PB9. LED3 is controlled by PB10. Setting PB8, PB9 or PB10 to a logic 1 value will turn on the associated LED.

Two interface connectors are provided to support each of these debugging approaches. These two connectors are designated the JTAG, J8connector and the Host Parallel Interface Connector, P2. 2.9.1 JTAG Connector The JTAG connector on the DSP56824EVM allows the connection of an external command converter for downloading programs and working with the DSP56824’s registers. This connector is used to communicate with an external command converter that passes information and data back and forth with a host processor running a debugger program.
