(2) Protection by
RES
(only the HN58C257A series)
The unprogrammable state can be realized by that the CPU’s reset signal inputs directly to the EEPROM’s
RES
pin.
RES
should be kept V
SS
level during V
CC
on/off.
The EEPROM breaks off programming operation when
RES
becomes low, programming operation doesn’t
finish correctly in case that
RES
falls low during programming operation.
RES
should be kept high for 10 ms
after the last data input.
