Introduction

The 56F8037EVM is used to demonstrate the abilities of the 56F8037 digital signal controller
and to provide a hardware tool allowing the development of applications.

The 56F8037EVM is an evaluation module board that includes a 56F8037 part, USB interface,
user LEDs, user pushbutton switches and a daughter card connector. The daughter card
connector allows signal monitoring and expandability of user features.

The 56F8037EVM is designed for the following purposes:

• Allowing new users to become familiar with the features of the 56800E architecture. The
tools and examples provided with the 56F8037EVM 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 memory, run it, and
debug it using a debugger via the JTAG/Enhanced OnCE (EOnCE) port. The breakpoint
features of the EOnCE 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 EOnCE 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 processor's peripherals.
The EOnCE port's unobtrusive design means that all memory on the board and on the
processor is available to the user.

1.1 56F8037EVM Architecture

The 56F8037EVM facilitates the evaluation of various features present in the 56F8037 part. The
56F8037EVM can be used to develop real-time software and hardware products. The
56F8037EVM provides the features necessary for a user to write and debug software,
