WRITE to PRECHARGE Command Interval (same bank) (BL = 4)
Precharge Termination in Write Cycles
During a burst write cycle without auto precharge, the burst write operation is terminated by a precharge command
of the same bank. In order to write the last input data, tWR (min) must be satisfied. When the precharge command
is issued, the invalid data must be masked by DM.
