21.2 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 78K0/KB1+ 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 78K0/KB1+ is
mounted on the target system.
Remark
The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
