Write Cycle 1 (WE Controlled)[19, 23, 24, 25]
Write Cycle 2 (CE1 or CE2 Controlled)
[19, 23, 24, 25]
Notes:
23. Data I/O is high-impedance if OE = VIH.
24. If CE1 goes HIGH and CE2 goes LOW simultaneously with WE = VIH, the output remains in a high-impedance state.
25. During this period, the I/Os are in output state and input signals should not be applied.
