30.5 Rewriting by Self Programming
30.5.1 Overview
memory by itself. By using this interface and a self programming library that is used to rewrite the flash memory with 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
rewritten in the field.
The V850ES/JG3-L supports a flash macro service that allows the user program to rewrite the internal flash
Note Be sure not to allocate the program code to the block where the constant data of the rewriting target is
allocated. See 30.2 Memory Configuration for the block configuration.
