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.
