WRITE CYCLE NO. 1 (WE CONTROLLED)
(6)
WE
Notes:
6.
CE
1
and
WE
are LOW and CE
2
is HIGH for WRITE cycle.
7.
OE
is LOW for this WRITE cycle to show twz and tow.
8. If
CE
1
goes HIGH or CE
2
goes LOW simultaneously with
WE
HIGH, the output remains in a high impedance state.
9. Write Cycle Time is measured from the last valid address to the first transitioning address.
