Write Cycle No. 1 (WE Controlled)
[15, 19, 20]
Write Cycle No. 2 (CE
Controlled)
[15, 19, 20]
Notes:
19.Data I/O is high impedance if OE = V
.
20.If CE goes HIGH simultaneously with WE = V
, the output remains in a high-impedance state.
21.During this period, the I/Os are in output state and input signals should not be applied.
