DM Control
DM can mask input data. By setting DM to low, data can be written. UDM and LDM can mask the upper and lower
byte of input data, respectively. When DM is set to high, the corresponding data is not written, and the previous data
is held. The latency between DM input and enabling/disabling mask function is 0.
