25.5.4 Communication commands
The RL78/G13 communicates with the dedicated flash memory programmer or external device by using commands.
The signals sent from the flash memory programmer or external device to the RL78/G13 are called commands, and the
signals sent from the RL78/G13 to the dedicated flash memory programmer or external device are called response.
