Reserved.
= 00: The receive slicer generates a mark if the voltage on RTIP/RRING exceeds 40% of the peak amplitude.
= 01: The receive slicer generates a mark if the voltage on RTIP/RRING exceeds 50% of the peak amplitude.
= 10: The receive slicer generates a mark if the voltage on RTIP/RRING exceeds 60% of the peak amplitude.
= 11: The receive slicer generates a mark if the voltage on RTIP/RRING exceeds 70% of the peak amplitude.

Reserved.
These bits select the internal pattern and insert it into transmit data stream.
= 00: Normal operation (PATT_CLK = 0) / insert all zeros (PATT_CLK = 1)
= 01: Insert All Ones
= 10: Insert PRBS (E1: 2
= 11: Insert programmable Inband loopback activate or deactivate code (default value 00001)
= 0: Uses TCLK as the reference clock
= 1: Uses MCLK as the reference clock
Inverts PRBS
= 0: The PRBS data is not inverted
= 1: The PRBS data is inverted before transmission and detection
LOS/AIS criterion is selected as below:
= 0: G.775 (E1) / T1.231 (T1/J1)
= 1: ETSI 300233& I.431 (E1) / I.431 (T1/J1)
AIS enable during LOS
= 0: AIS insertion on RDP/RDN/RCLK is disabled during LOS
= 1: AIS insertion on RDP/RDN/RCLK is enabled during LOS
Automatically Transmit All Ones (enabled only when PATT[1:0] = 01)
= 0: Disabled
= 1: Automatically Transmit All Ones pattern at TTIP/TRING during LOS
