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/OnCE
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 hybrid
controller's peripherals. The OnCE port's unobtrusive design means that all of the
memory on the board and on the hybrid controller chip are available to the user.
1.1 56F827EVM Architecture
The 56F827EVM facilitates the evaluation of various features present in the 56F827 part.
The 56F827EVM can be used to develop real-time software and hardware products based
on the 56F827. The 56F827EVM provides the features necessary for a user to write and
debug software, demonstrate the functionality of that software and interface with the
