RL78/G1P
23.5.4 Communication commands
The RL78/G1P 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/G1P are called commands, and the
signals sent from the RL78/G1P to the dedicated flash memory programmer or external device are called response.
The flash memory control commands of the RL78/G1P are listed in the table below. All these commands are issued
from the programmer or external device, and the RL78/G1P performs processing corresponding to the respective
commands.

Note Confirm that no data has been written to the write area. Because data cannot be erased after block erase is
prohibited, do not write data if the data has not been erased.
The RL78/G1P returns a response for the command issued by the dedicated flash memory programmer or external
device. The response names sent from the RL78/G1P are listed below.
