Chapter 1
Introduction
The 56F803EVM is used to demonstrate the abilities of the 56F803 and to provide a hardware
tool allowing the development of applications that use the 56F803.
The 56F803EVM is an evaluation module board that includes a 56F803 part, peripheral
expansion connectors, external memory, RS-232 interface and a CAN interface. The expansion
connectors are for signal monitoring and user feature expandability.
The 56F803EVM 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 56F803EVM 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
TM
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 controller’s peripherals.
The OnCE port's unobtrusive design means that all of the memory on the board and on the
chip are available to the user.

1.1 56F803EVM Architecture
The 56F803EVM facilitates the evaluation of various features present in the 56F803 part. The
56F803EVM can be used to develop real-time software and hardware products based on the
56F803. The 56F803EVM provides the features necessary for a user to write and debug
software, demonstrate the functionality of that software and interface with the customer's
application-specific device(s). The 56F803EVM is flexible enough to allow a user to fully

1.3 56F803EVM Connections
An interconnection diagram is shown in Figure 1-3 for connecting the PC and the external +12V
DC power supply to the 56F803EVM board.
Figure 1-3. Connecting the 56F803EVM Cables
Perform the following steps to connect the 56F803EVM cables:
1. Connect the parallel extension cable to the Parallel port of the host computer.
2. Connect the other end of the parallel extension cable to P2, shown in Figure 1-3, on the
56F803EVM board. This provides the connection which allows the host computer to
control the board.
3. Make sure that the external +12V DC, 4.0A power supply is not plugged into a +120V AC
power source.
4. Connect the 2.1mm output power plug from the external power supply into P3, shown in
Figure 1-3, on the 56F803EVM board.
5. Apply power to the external power supply. The green Power-On LED will illuminate
when power is correctly applied.

Technical Summary
The 56F803EVM is designed as a versatile controller development card for developing real-time
software and hardware products to support a new generation of applications in digital and
wireless messaging, servo and motor control, digital answering machines, feature phones,
modems, and digital cameras. The power of the 16-bit 56F803 controller, combined with the
on-board 64K u16-bit external program Static RAM (SRAM), 64K u16-bit external data
SRAM, CAN interface, Hall-Effect/Quadrature Encoder interface, motor zero crossing logic,
motor bus over-current logic, motor bus over-voltage logic and parallel JTAG interface, makes
the 56F803EVM ideal for developing and implementing many motor controlling algorithms, as
