Figure 33. Burst READ at End-of-Row (Wrap Off)
Note:
1. Non-default BCR settings for burst READ at end of row : fixed or variable latency, WAIT active LOW; WAIT asserted during delay.
2. For burst READs, CE# must go HIGH before the second CLK after the WAIT period begins ( before the second CLK after WAIT asserts with BCR[8]=0, or before the
third CLK after WAIT asserts with BCR[8]=1 ).
