rx_dataoutfull[24]- rx_ctrldetect (MSB)
Two Receiver Error Detect Bits
rx_dataoutfull[9] - rx_errdetect (LSB) and
rx_dataoutfull[25]- rx_errdetect (MSB)
Two Receiver Sync Status Bits
rx_dataoutfull [10] - rx_syncstatus (LSB) and
rx_dataoutfull[26] - rx_syncstatus (MSB)
Two Receiver Disparity Error Bits
rx_dataoutfull [11] - rx_disperr (LSB) and
rx_dataoutfull[27] - rx_disperr (MSB)
Two Receiver Pattern Detect Bits
rx_dataoutfull[12] - rx_patterndetect (LSB) and
rx_dataoutfull[28]- rx_patterndetect (MSB)

FIFO deletion status indicator (rx_rmfifodatadeleted) in
non-PIPE/PCIe modes
rx_dataoutfull[14] and rx_dataoutfull[46]: Rate Match
FIFO insertion status indicator (rx_rmfifodatainserted) in
