In the normal operation mode, input a voltage of EV
programming mode, supply a write voltage of EV
Because the FLMD0 pin serves as a write protection pin in the self programming mode, a voltage of EV
must be supplied to the FLMD0 pin via port control, etc., before writing to the flash memory. For details, see
22.5.5 (1) FLMD0 pin.
