Bit 7 to 4: Receiver Signal Level 3 to 0 (RSL[3:0]). This read-only real-time status field indicates the incoming
signal level at the LIU receiver. Note that the range of signal levels reported this field is limited by the equalizer gain
limit (EGL) in short-haul applications. See section 10.13.3.3.

Bit 0: Receive Failure (RFAIL).
This is a read-only real-time status bit.
0 = No short detected on the RTIP/RRING pin
s
1 = Short detected on the RTIP/RRING pins
