Table 35. Deﬁnition of the Status Bits of MRWDx that Vary for Different Channels

The code violation signals will only be valid if the corresponding CV_SELx = “1”. (If 8b10bR=0, CV_SEL should

also be zero. The CV_x_OR signals are obtained by ORing four code violation signals from the 1:4 DEMUX block.

These are primarily indicators of received signal quality, since a single code violation will not force a loss of sync
