Write Cycle No. 1 (WE Controlled)
[8, 13, 14]
Write Cycle No. 2 (CE Controlled)
[8, 13, 14]
Write Cycle No. 3 (WE Controlled, OE LOW)
[9, 14]
Notes:
13. Data I/O is high impedance if OE
= V
IH
.
14. If CE
goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
15. During this period, the I/Os are in the output state and input signals should not be applied.
