Cautions 1. During address transition, at least one of pins /CE1, CE2, /WE should be inactivated.
2. Do not input data to the I/O pins while they are in the output state.
Remark
Write operation is done during the overlap time of a low level /CE1, a low level /WE, a low level /LB (or low
level /UB) and a high level CE2.
