Note : 1. Non-default BCR settings for burst WRITE interrupted by burst WRITE or READ in fixed latency mode: Fixed latency;
latency code 2(3 clocks); WAIT active LOW; WAIT asserted during delay.
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 tCEM.
