DQM Function(CL=3)
DQM CONTROL
DQM is a dual function signal defined as the data mask for
writes and the output disable for reads. During writes, DQM(U,L)
masks input data word by word. DQM(U,L) to write mask latency
is 0. During reads, DQM(U,L) forces output to Hi-Z word by word.
DQM(U,L) to output Hi-Z latency is 2.
