Notes
Document #: 38-05006 Rev. *H
11. Device is continuously selected. OE, CE = V
12. WE is HIGH for read cycles.
13. Address valid before or similar to CE transition LOW.
14. Data I/O is high impedance if OE = V
15. If CE goes HIGH simultaneously with WE HIGH, the output remains in high impedance state.
16. During this period, the I/Os are in output state. Do not apply input signals.
