CHAPTER 27 FLASH MEMORY (TWO POWER)
27.2 Writing with Flash Programmer
Data can be written to the flash memory on-board or off-board, by using a dedicated flash programmer.
(1) On-board programming
The contents of the flash memory can be rewritten after the V850ES/KJ1 has been mounted on the target
system. The connectors that connect the dedicated flash programmer must be mounted on the target system.
(2) Off-board programming
Data can be written to the flash memory with a dedicated program adapter (FA series) before the V850ES/KJ1
is mounted on the target system.
Remark The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
