25.5 Programming Method
25.5.1 Controlling flash memory
25.5.2 Flash memory programming mode
microcontrollers in the flash memory programming mode. To set the mode, set the TOOLC0/TOOLC1 pins to V
clear the reset signal.
25.5.3 Communication commands
The 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 flash memory control commands of the 78K0/Kx2-L microcontrollers are listed in the table below. All these
