Introduction
This application note applies to the MC68HC908LB8, MC68HC908QL4, MC68HC908QB4/QB8/QY8,
and MC68HC908QY4A Series
1
FLASH-based microcontroller units (MCUs). To program, erase, and
verify FLASH, these MCUs have on-chip FLASH support routines residing in ROM (read-only memory).
These routines may be accessed in either user mode or monitor mode and eliminate the need to develop
separate FLASH routines for applications.
This application note describes how to call each of the routines in user software, what is performed, and
what is returned as confirmation of routine execution. The software files are available as a zip file,
AN2635SW, from the Freescale Semiconductor website: www.freescale.com

With the exception of mask set errata documents, if any other
