Flash Programming
Operational or test code can be programmed into the flash memory using either an in-circuit emulator or the Flash Download
Board Module (FDBM) available from TERIDIAN. The flash programming procedure uses the E_RTS, E_RXTX, and E_TCLK
pins.
MPU Firmware Library
All application-specific MPU functions mentioned above under “Application Information” are available from TERIDIAN as a
standard ANSI C library and as ANSI “C” source code. The code is available as part of the Demonstration Kit for the 71M6403.
The Demonstration Kits come with the 71M6403 IC preprogrammed with demo firmware mounted on a functional example of a
circuit breaker PCB (Demo Board). The Demo Boards allow for quick and efficient evaluation of the IC without having to write
firmware or having to supply an in-circuit emulator (ICE).
A reference guide for firmware development on the 71M6403 is available as a separate document (Software User’s Guide,
“SUG”). The User’s Manual supplied with the Demo Kit contains MPU address maps for the demo code as well as other useful
information, such as sample calibration procedures.
