Introduction
This engineering bulletin describes how to perform in-circuit
programming (ICP) of the FLASH memory using monitor mode for the
MC68HC908SR12.

Two ICP methods are discussed here:
• Using the M68ICS08SR in-circuit simulator (ICS) with P&E
   Microcomputer Systems software
• Using P&E Microcomputer Systems software with an external
   communications circuit

ICP is a process where user code is programmed into the device’s
FLASH memory after the part has been assembled into the application.
ICP also allows the original users code to be erased and
re-programmed. This method can be used in development,
production/manufacturing, and in a field environment.
