Figure 32. READ Burst Suspend
Note:
1. Non-default BCR settings for READ burst suspend: Fixed or variable latency; latency code two (three clocks); WAIT active LOW; WAIT asserted
2. CLK can be stopped LOW or HIGH, but must be static, with no LOW-to-HIGH transitions during burst suspend.
3. OE# can stay LOW during burst suspend. If OE# is LOW, DQ[15:0] will continue to output valid data.
