WRITE Burst Identified
( WE # = LOW )
Don‟t Care
Note : 1. Non-default BCR settings for burst WRITE operation in variable latency mode; Latency code 2)3 clocks); WAIT active
LOW; WAIT a 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 required if tCSP > 20ns.
