LS_RX_INVPAIR LS Serdes lane outputs polarity on the receive channel.
0 = Normal polarity. OUTxyP considered positive data. OUTxyN considered negative data
(Default 1’b0)
1 = Inverted polarity. OUTxyP considered negative data. OUTxyN considered positive data
14
LS_TX_INVPAIR LS Serdes lane inputs polarity on the transmit channel.
0 = Normal polarity. INxyP considered positive data and INxyN considered negative data
(Default 1’b0)
1 = Inverted polarity. INxyP considered negative data and INxyP considered positive data

HS_LOS_MASK
0 = HS Serdes LOS status is used to generate HS channel synchronization status. If
HS Serdes indicates LOS, channel synchronization indicates synchronization is not
achieved
1 = HS Serdes LOS status is not used to generate HS channel synchronization status
