DQMB Control
The DQMB mask the DQ data. The timing of DQMB is different during reading and writing.
Reading:
When data is read, the output buffer can be controlled by DQMB. By setting DQMB to Low,
the output buffer becomes Low-Z, enabling data output. By setting DQMB to High, the output buffer
becomes High-Z, and the corresponding data is not output. However, internal reading operations continue.
The latency of DQMB during reading is 3 clocks.
Writing:
Input data can be masked by DQMB. By setting DQMB to Low, data can be written. In
addition, when DQMB is set to High, the corresponding data is not written, and the previous data is held.
The latency of DQMB during writing is 1 clock.
