Disable Digital LOS Detector - Channel_n:
This READ/WRITE bit-field is used to enable or disable the Digital LOS
(Loss of Signal) Detector within Channel_n, as described below.
0 - Enables the Digital LOS Detector within Channel_n.
1 - Disables the Digital LOS Detector within Channel_n.
N
Disable Analog LOS Detector - Channel_n:
This READ/WRITE bit-field is used to either enable or disable the Analog
LOS (Loss of Signal) Detector within Channel_n, as described below.
0 - Enables the Analog LOS Detector within Channel_n.
1 - Disables the Analog LOS Detector within Channel_n.

Receive Clock Invert Select - Channel_n:
This READ/WRITE bit-field is used to select the edge of the RxCLK_n out-
put that the Receive Section of Channel_n will use to output the recovered
data via the RxPOS_n and RxNEG_n output pins, as described below.
0 - Configures the Receive Section (within the corresponding channel) to
output the recovered data via the RxPOS_n and RxNEG_n output pins upon
the rising edge of RCLK_n.
1 - Configures the Receive Section (within the corresponding channel) to
output the recovered data via the RxPOS_n and RxNEG_n output pins upon
the falling edge of RCLK_n.
