Each bus indicates which PCS lane
will have its status reflected on a specific status pins. For
example, STAT_RX_PCSL_NUMBER_0 indicates
which PCS lane will have its status reflected on pin 0 of the other
status signals. These buses can be used to detect if a PCS lane has
not been found or if one has been mapped to multiple status
pins.
