Notes:
14. Address valid prior to or coincident with CE transition LOW.
15. Data I/O is high impedance if OE = VIH.
16. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
17. During this period, the I/Os are in output state and input signals should not be applied.
