2.2 Protection by RES (only the HN58V66A series)
EEPROM’s RES pin. RES should be kept V

in case that RES falls low during programming operation. RES should be kept high for 10 ms after
the last data input.
The unprogrammable state can be realized by that the CPU’s reset signal inputs directly to the
