PROGRAMMING ON-BOARD FLASH MEMORY
B.1 OVERVIEW

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 MC68VZ328 before reading the material below. For more details on Bootstrap mode,
