12.3 Terminating a Burst Write Cycle by Precharge Command
During a burst write cycle without auto precharge, the burst write operation is terminated by a precharge command
of the same banks. In order to write the last input data to the memory cell correctly, tWR (MIN.) must be satisfied. When
the precharge command is issued at the rising edge of the clock (CLK), the invalid data from the burst write cycle
must be masked by DM.
