Notes
15. The device is continuously selected. OE, CE1 = VIL, CE2 = VIH.
16. WE is HIGH for read cycle.
17. Address valid before or similar to CE1 transition LOW and CE2 transition HIGH.
18. Data I/O is high impedance if OE = VIH.
19. If CE1 goes HIGH or CE2 goes LOW simultaneously with WE HIGH, the output remains in high impedance state.
20. During this period, the IOs are in output state. Do not apply input signals.
