Write Cycle Timing Chart 2 (/CE1 Controlled)
Cautions 1. During address transition, at least one of pins /CE1, CE2, /WE should be inactivated.
Remark
16
Address (Input)
2. Do not input data to the I/O pins while they are in the output state.
Write operation is done during the overlap time of a low level /CE1, /WE and a high level CE2.
