Data can be written to the flash memory on-board or off-board, by using a dedicated flash memory programmer.
The contents of the flash memory can be rewritten after the 78K0/FE2 has been mounted on the target system.
The connectors that connect the dedicated flash memory programmer must be mounted on the target system.
Data can be written to the flash memory with a dedicated program adapter (FA series) before the 78K0/FE2 is
mounted on the target system.
Remark The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.

using the clock output of the dedicated flash memory programmer, pin connection varies depending on the
type of the dedicated flash memory programmer used.
