C.1 OVERVIEW

The Flash memory on the ADS board cannot be written directly. A special program com- mand sequence is required to unlock it before starting the write process. A flash program is therefore provided with the ADS board for helping users to do re-programming. The sections below will describe the program and provide further information about the process and other required elements.

It is recommended that user should have a basic understanding of bootstrap mode operation of MC68EZ328 before reading the material below. For more details on Bootstrap mode, please refer to the MC68EZ328 user’s manual.
