READ/WRITE TIMING3
NOTE:
1. Q(A4) refers to output from address A. Q(A4+1) refers to output from the next internal burst address following A4.
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. The data bus (Q) remains in High-A following a WRITE cycle unless an ADSP\, ADSC\ or ADV\ cycle is performed.
4. GW\ is HIGH.
5. Back-to-back READs may be controlled by either ADSP\ or ADSC\.
