Cautions 1. During address transition, at least one of pins /CS, /WE should be inactivated.
2. Do not input data to the I/O pins while they are in the output state.
3. If the address is changed using a value that is either lower than the minimum value or higher
than the maximum value for the write cycle time (t
WC
), none of the data can be guaranteed.
Remark
Write operation is done during the overlap time of a Low /CS, /WE, /LB and/or /UB.
