Notes:
11. This cycle is OE Controlled and WE is HIGH read cycle.
12. Address valid prior to or coincident with CE transition LOW.
13. This cycle is WE controlled, OE is HIGH during write.
14. Data In/Out is high impedance if OE = VIH.
15. During this period the I/Os are in output state and input signals should not be applied.
