Notes
Document #: 38-05442 Rev. *H
19. Device is continuously selected. OE, CE = V
20. WE is HIGH for read cycles.
21. Address valid before or similar to CE transition LOW.
22. Data I/O is high impedance if OE = V
23. If CE goes HIGH simultaneously with WE HIGH, the output remains in high impedance state.
24. During this period, the I/Os are in output state and input signals must not be applied.
