DQM Control
The UDQM and LDQM mask the upper and lower bytes of the DQ data, respectively. The timing of UDQM and
LDQM is different during reading and writing.

Reading
When data is read, the output buffer can be controlled by UDQM and LDQM. By setting UDQM and LDQM to Low,
the output buffer becomes Low-Z, enabling data output. By setting UDQM and LDQM to High, the output buffer
becomes High-Z, and the corresponding data is not output. However, internal reading operations continue. The
latency of UDQM and LDQM during reading is 2 clocks.
Writing
Input data can be masked by UDQM and LDQM. By setting DQM to Low, data can be written. In addition, when
UDQM and LDQM are set to High, the corresponding data is not written, and the previous data is held. The latency
of UDQM and LDQM during writing is 0 clock.
