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 71M6511
and 71M6511H ICs. The Demonstration Kits come with the 71M6511 or 71M6511H IC preprogrammed with demo firmware
mounted on a functional sample meter 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 71M6511 and 71M6511H is available as a separate document (Software
User’s Guide, “SUG”). The User’s Manuals supplied with the Demo Kits contain MPU address maps for the demo code as well
as other useful information, such as sample calibration procedures.
