18.7 On-Board and Off-Board Flash Memory Programming
18.7.1 Flash memory programming mode
78K0S/KA1+ in the flash memory programming mode. When the 78K0S/KA1+ is connected to the flash memory
programmer and a communication command is transmitted to the microcontroller, the microcontroller is set in the flash
memory programming mode.
18.7.2 Communication commands
the flash memory programmer to the 78K0S/KA1+ are called communication commands, and the commands sent
from the 78K0S/KA1+ to the dedicated flash memory programmer are called response.
