(SYNCHRONOUS BURST WRITE CYCLE - CS Toggling Consecutive Burst Write)
1. The new burst operation can be issued only after the previous burst operation is finished. For the new burst operation, tBEADV
should be met.
2. Multiple clock risings are allowed during low ADV period. The burst operation starts from the first clock rising.
3. /WAIT Low(tWL or tAWL) : Data not available(driven by CS low going edge or ADV low going edge)
/WAIT High(tWH) : Data available(driven by Latency-1 clock)
/WAIT High-Z(tWZ) : Data don’t care(driven by CS high going edge)
4. D2 is masked by UB and LB.
5. Burst Cycle Time(tBC) should not be over 2.5µs.
