Write Cycle No. 1 (CE Controlled)[15, 16]
Write Cycle No. 2 (WE Controlled, OE HIGH During Write)[15, 16]
Notes:
15. Data I/O is high impedance if OE = VIH.
16. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
17. During this period the I/Os are in the output state and input signals should not be applied.
