Notes: 1.Non-default BCR settings for burst WRITE operation in fixed latency mode: fixed latency, latency code 2 (3 clocks), WAIT
active LOW, WAIT asserted during delay, burst length 4, burst wrap enabled.
2.WAIT asserts for LC cycles for both fixed and variable latency. LC = latency code (BCR[13:11]).
3. tAS is required if tCSP > 20ns.
4.CE# must go HIGH before any clock edge following the last word of a defined-length burst.
