Notes:
11.
CE
1
and
WE
must
be
LOW,
and
CE2
HIGH
for
WRITE
cycle.
12. OE is LOW for this WRITE cycle to show tWZ and tOW.
13.
If
CE
1
goes
HIGH,
or
CE2
goes
LOW,
simultaneously
with
WE
HIGH,
the output remains in a high impedance state.
14. Write Cycle Time is measured from the last valid address to the first
transitioning address.
