NOTE:
1. Q(A2) refers to output from address A2. Q(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. Timing is shown assuming that the device was not enabled before entering into this sequence. OE# does not cause Q
to be driven until after the following clock rising edge.
4. Outputs are disabled within two clock cycles after deselect.
