Receive slicer threshold
= 00: The receive slicer generates a mark if the voltage on RTIPn/RRINGn exceeds 40% of the peak amplitude.
= 01: The receive slicer generates a mark if the voltage on RTIPn/RRINGn exceeds 50% of the peak amplitude.
= 10: The receive slicer generates a mark if the voltage on RTIPn/RRINGn exceeds 60% of the peak amplitude.
= 11: The receive slicer generates a mark if the voltage on RTIPn/RRINGn exceeds 70% of the peak amplitude.
