25.5 Programming Method
25.5.1 Controlling flash memory
25.5.2 Flash memory programming mode
microcontrollers in the flash memory programming mode. The system switches to the flash memory programming mode
once the dedicated flash memory programmer is connected and communication starts.
25.5.3 Communication commands
signals sent from the flash memory programmer to the 78K0/Kx2-L microcontrollers are called commands, and the signals
sent from the 78K0/Kx2-L microcontrollers to the dedicated flash memory programmer are called response.
commands are issued from the programmer and the 78K0/Kx2-L microcontrollers perform processing corresponding to the
respective commands.

The following figure illustrates the procedure to manipulate the flash memory.
To rewrite the contents of the flash memory by using the dedicated flash memory programmer, set the 78K0/Kx2-L
Change the mode by using a jumper when writing the flash memory on-board.
The 78K0/Kx2-L microcontrollers communicate with the dedicated flash memory programmer by using commands. The
The flash memory control commands of the 78K0/Kx2-L microcontrollers are listed in the table below. All these
