Write Cycle No. 2
(CE Controlled)
16 17 18
Notes:
13. This cycle is WE controlled, OE is HIGH during write.
14. Data In/Out is high impedance if OE = V
IH
.
15. During this period the I/Os are in output state and input signals should not be applied.
16. This cycle is CE controlled.
17. Data In/Out is high impedance if OE = V
IH
.
18. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
