Notes:

15.Address valid prior to or coincident with CE transition LOW.

16.Data I/O is high impedance if OE = VIH.

17.During this period, the I/Os are in output state and input signals should not be applied.

18.If CE goes HIGH simultaneously with WE HIGH, the output remains in high-impedance state.
