PCS‑VLANE Registers
Table 3-38: PCS‑VLANE Registers
When the RX PCS is properly locked, the PCS-VLANE registers contain a permutation of the numbers [0–19]
stored in 5-bit values. You may need this information to isolate a problem with the remote transmitter. Any
problem with the permutation, for example two lanes with the same number, stops the reception of valid data.
