Write Cycle No. 1 (WE Controlled)
[14, 18, 19]
Write Cycle No. 2 (CE
Controlled)
[14, 18, 19]
Notes:
18. Data I/O is high impedance if OE = V
IH
.
19. If CE goes HIGH simultaneously with WE = V
IH
, the output remains in a high-impedance state.
20. During this period, the I/Os are in output state and input signals should not be applied.
