Introduction

The intent of this application note is to introduce a standard method for implementing HCS12 FLASH
erase and programming functions for devices with single FLASH array implementations. The example
presented here enables the HCS12 user to program / erase FLASH locations conveniently from user
code.

In the HCS12 Family, there are different implementations of the various FLASH memories in several
devices. Fo
