31.5 Rewriting by Self Programming
31.5.1 Overview
The V850ES/JG3-H and V850ES/JH3-H support a flash macro service that allows the user program to rewrite the
internal flash 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
Note
can be
rewritten in the field.
Note Be sure not to allocate the program code to the block where the constant data of rewriting target is allocated.
See 31.2 Memory Configuration for the block configuration.
