Write command to Precharge command interval (same bank)
When the precharge command is executed for the same bank as the write command that preceded it, the minimum
interval between the two commands is 1 clock. However, if the burst write operation is unfinished, the input data
must be masked by means of DQM for assurance of the clock defined by tDPL.
