Freescale Semiconductor Application Note
AN2635 Rev. 4, 10/2005
On-Chip FLASH Programming Routines
For MC68HC908LB8, MC68HC908QL4, MC68HC908QB8, MC68HC908QB4, MC68HC908QY8, and MC68HC908QY4A Series1

Introduction
This application note applies to the MC68HC908LB8, MC68HC908QL4, MC68HC908QB4/QB8/QY8, and MC68HC908QY4A Series1 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.
