memory programmer change to the high-impedance status. These port pins need not be processed. If problems such
as disabling of the high-impedance status should occur to the external devices connected to the ports, connect them
to EV

DD0
When 0 V is input to the FLMD0 pin, the FLMD1 pin does not function. When EV
(V850E/IG3 only) is supplied to the FLMD0 pin, the flash memory programming mode is entered, so 0 V must
be input to the FLMD1 pin. The following shows an example of the connection of the FLMD1 pin.
