Write Cycle No. 1 (WE Controlled)[10, 16, 17]
Write Cycle No. 2 (CE Controlled)[10, 16, 17]
Notes:
16. Data I/O is high impedance if OE = VIH.
17. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
18. During this period, the I/Os are in the output state and input signals should not be applied.
