11 TX_DM Output data. TX_DIFFMODE=1, Ignored
TX_DIFFMODE=0, Drives DPM only. TX_DM_OE=1 to
enable drive. DPM=TX_DM
RW 0x0
10 TX_DP Output data. If TX_DIFFMODE=1, Drives DPP/DPM diff
pair. TX_DP_OE=1 to enable drive. DPP=TX_DP,
DPM=~TX_DP
If TX_DIFFMODE=0, Drives DPP only. TX_DP_OE=1 to
enable drive. DPP=TX_DP
RW 0x0
9 TX_DM_OE Output enable. If TX_DIFFMODE=1, Ignored.
If TX_DIFFMODE=0, OE for DPM only. 0 - DPM in Hi-Z
state; 1 - DPM driving
RW 0x0
8 TX_DP_OE Output enable. If TX_DIFFMODE=1, OE for DPP/DPM diff
pair. 0 - DPP/DPM in Hi-Z state; 1 - DPP/DPM driving
If TX_DIFFMODE=0, OE for DPP only. 0 - DPP in Hi-Z state;
1 - DPP driving
