DM Control
DM can mask input data. In ×16 products, UDM and LDM can mask the upper and lower byte of input data,
respectively. By setting DM to Low, data can be written. 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.
