Bits 7 to 0: Remote Loopback Control Bits Channel n (RLBCn). When this bit is set, remote loopback is
enabled on LIUn. The analog received signal goes through the receive digital and is looped back to the transmitter.
The data at TPOS and TNEG is ignored. The jitter attenuator is in use if enabled.

Bits 7 to 0: Transmit All Ones Enable Channel n (TAOEn). When this bit is set, continuous stream of all ones on
TTIP and TRING are sent on Channel n. MCLK is used as a reference clock for Transmit All Ones Signal. The data
arriving at TPOS and TNEG is ignored.

Bits 7 to 0: Loss of Signal Status Channel n (LOSSn). When this bit is set, an LOS condition has been detected
on LIUn. The criteria and conditions of LOS are described in Section 5.5.6.
