[ Write Interrupted by Precharge ]
Burst write operation can be interrupted by precharge of the same bank. Write recovery time (tWR) is
required from the last data to PRE command. During write recovery, data inputs must be masked by
DQM.
[ Write Interrupted by Burst Terminate ]
Burst terminate command can terminate burst write operation. In this case, the write recovery time is
not required and the bank remains active. WRITE to TBST interval is minimum 1 CLK.
