Introduction

The 56F827EVM is used to demonstrate the abilities of the 56F827 and to provide a hardware tool allowing the development of applications that use the 56F827.

The 56F827EVM is an evaluation module board that includes a 56F827 part, 16-bit stereo codec, external memory and a daughter card expansion interface. The daughter card expansion connectors are for signal monitoring and user feature expandability.

The 56F827EVM is designed for the following purposes:

• Allowing new users to become familiar with the features of the 56800 architecture. The tools and examples provided with the 56F827EVM facilitate evaluation of the feature set and the benefits of the family.

• Serving 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, run it, and debug it using a debugger via the JTAG/OnCETM port. The breakpoint features of the OnCE port enable the user to easily specify complex 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.

• Serving 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 controllers peripherals. The OnCE ports unobtrusive design means that all of the memory on the board and on the controller chip are available to the user.
