NOTE:
1. Q(A4) refers to output from address A4. 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-Z 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#.
6. Timing is shown assuming that the device was not enabled before entering into this sequence.
