2. CE2# and CE2 have timing identical to CE#. On this diagram, when CE# is LOW, CE2# is LOW and CE2 is HIGH.
3. OE# must be HIGH before the input data setup and held HIGH throughout the data hold time. This prevents
4. ADV# must be HIGH to permit a WRITE to the loaded address.
5. Full-width WRITE can be initiated by GW# LOW; or GW# HIGH and BWE#, BWa# and BWb# LOW for x18 device;
