56800E Flash Programmer User Guide

The 56800E Flash Programmer provides a means to program the on-chip Flash of the 56800E DSC family. 
The Flash Memory blocks are programmed 

in circuit

, using the JTAG/EOnCE interface. The 56800E 

Flash Programmer is suitable for both a low volume production environment as well as for in-field 
firmware upgrades.

The 56800E Flash Programmer runs under a 32-bit Windows environment on PC compatible computers. 
A Parallel Command Converter or CodeWarrior USB TAP is needed to provide the interface between the 
JTAG/OnCE interface of the target system and the computer. The connection is outlined in the figure 
below.

The 56800E Flash Programmer is provided in two forms. The first is command-line oriented to allow easy 
integration with scripts. The second is a GUI running under windows to allow easy rapid Flash loading 
onto the target device. The command line version is backwards compatible with the old 

Flash over JTAG

tool.
