4.11 Connecting the Emulator Port Pins
Even when the emulator is not used, small shunt capacitors to ground (22 pF) should be used for protection
from EMI as illustrated in
4.12 Flash Programming
4.12.1 Flash Programming via the ICE Port
Operational or test code can be programmed into the flash memory using either an in-circuit emulator or
the Flash Programmer Module (TFP-2) available from Teridian. The flash programming procedure uses
the E_RST, E_RXTX, and E_TCLK pins.
4.12.2 Flash Programming via the SPI Port
It is possible to erase, read and program the flash memory of the 71M6543 via the SPI port. See
2.5.12
4.13 MPU Demonstration Code
All application-specific MPU functions mentioned in
demonstration C source code supplied by Teridian. The code is available as part of the Demonstration Kit
for the 71M6543. The Demonstration Kits come with the 71M6543 preprogrammed with demonstration
firmware and mounted on a functional sample meter 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).
