Write Cycle No. 2 (WE Controlled, OE HIGH During Write)[13, 14]
Write Cycle No. 3 (WE Controlled, OE LOW)[14]
Notes:
13. Data I/O is high impedance if OE = VIH.
14. If CE1 goes HIGH or CE2 goes LOW simultaneously with WE going HIGH, the output remains in a high-impedance state.
15. During this period the I/Os are in the output state and input signals should not be applied.
