In-Circuit Programming of FLASH Memory Using
the Monitor Mode for the MC68HC908MR16/32
By Timothy J. Airaudi
Applications Engineering, Microcontroller Division
Austin, Texas
Introduction
This engineering bulletin describes how to perform in-circuit
programming (ICP) of the FLASH memory using monitor mode.
Two methods are discussed here:
• Using the M68ICS08MR in-circuit simulator (ICS) with P&E
Microsystems software
• Using an external communications circuit with P&E Microsystems
software
ICP is a process in which user code is programmed into the device’s
FLASH memory after the part has been assembled into the application.
ICP alsoallowsthe original user code to be erased and re-programmed.
This method can be used in development, production/manufacturing,
and in a field environment.
