Write Cycle 1 (WE Controlled)[15, 19, 20, 21]
Write Cycle 2 (CE1 or CE2 Controlled)
[15, 19, 20, 21]
Notes:
19. Data IO is high impedance if OE = VIH.
20. If CE1 goes HIGH and CE2 goes LOW simultaneously with WE = VIH, the output remains in a high-impedance state.
21. During this period, the IOs are in output state and input signals should not be applied.
