Write Burst Identified (WE#=LOW)
Notes:
1. Non-default BCR settings for burst WRITE operation, with fixed-length burst of 4, burst wrap enabled:
Fixed latency; latency code two (three clocks); WAIT active LOW; WAIT asserted during delay.
2. WAIT asserts for LC cycles for both fixed and variable latency. LC = latency code (BCR[13:11]).
3. tAS required if tCSP > 20ns.
