CHAPTER 21 FLASH MEMORY
21.7 Rewriting by Self Programming
21.7.1 Overview
The V850ES/SA2 and V850ES/SA3 support a flash macro service that allows the internal flash memory to be
rewritten by the user program itself. By using this interface and a self programming library that is used to rewrite the
flash memory via a user application program, the flash memory can be rewritten by a user application transferred in
advance to the internal RAM or external memory. Consequently, the user program can be upgraded and constant
data can be rewritten in the field.
