programming mode, supply a write voltage of V
Because the FLMD0 pin serves as a write protection pin in the self programming mode, a voltage of V
must be supplied to the FLMD0 pin via port control, etc., before writing to the flash memory. For details, see
30.5.5 (1) FLMD0 pin.
When 0 V is input to the FLMD0 pin, the FLMD1 pin does not function. When V
pin, the flash memory programming mode is entered, so 0 V must be input to the FLMD1 pin. The following
