NOTES:
1. D (A2) refers to output from address A2. D (A2+1) refers to output from the next internal burst address following A2.
2. CE2 and CE2 have timing identical to CE. On this diagram, when CE is LOW, CE2 is LOW and CE2 is HIGH. When CE is HIGH, CE2 is HIGH and
CE2 is LOW.
3. OE must be HIGH before the input data setup and held HIGH throughout the data hold time. This prevents input/output data contentin for the
time period prior to the byte write enable inputs being sampled.
4. ADV must be HIGH to permit a WRITE to the load address.
5. Full-width WRITE can be initiated by GW LOW, or GW HIGH and BWE, BWa, - BWd LOW. Timing is shown assuming that the device was not
enabled before entering into its sequence. OE does not cause Q to be driven until after the following clock rising edge.
