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