Data In D1
Cautions 1. During address transition, at least one of pins /CE1 and /WE, or both of /LB and /UB pins should
be inactivated.
2. Do not input data to the DQ pins while they are in the output state.
3. In write cycle, CE2 and /OE should be fixed HIGH.
4. CLK should be fixed HIGH or LOW.
Remark
Write operation is done during the overlap time of LOW of following signals.
/CE1
/WE
/LB and/or /UB
