Figure 45. Burst WRITE Interrupted by Burst WRITE or READ - Variable Latency Mode
Note:
1. Non-default BCR settings for burst WRITE interrupted by burst WRITE or READ in variable latency mode: Variable latency; latency code two
2. Burst interrupt shown on first allowable clock (i.e., after first data word written).
3. CE# can stay LOW between burst operations, but CE# must not remain LOW longer than t
(three clocks); WAIT active LOW; WAIT asserted during delay. All bursts shown for variable latency; no refresh collision.
