Document #: 38-05071 Rev. *D Page 7 of 10
Write Cycle No. 1 (WE Controlled)
[9, 14, 15]
Write Cycle No. 2 (CE Controlled)
[9, 14, 15]
Write Cycle No. 3 (WE Controlled, OE LOW)
[10, 15]
Notes:
14.Data I/O is high impedance if OE
= V
IH
.
15.If CE
goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
16.During this period, the I/Os are in the output state and input signals should not be applied.
