DQM CONTROL
DQMB0-7 is a dual function signal defined as the data mask for writes and the output
disable for reads. During writes, DQMB0-7 masks input data word by word. DQMB0-7
to write mask latency is 0.
During reads, DQMB0-7 forces output to Hi-Z word by word. DQMB0-7 to output Hi-Z
latency is 2.
