Bit 7: Receiver Transformer Turns Ratio Channel 4(RTR4).
If this bit is set the Turns Ratio is 1:1 on the receiver
side. This bit should be set when a 1:1 receiver transformer is used and is recommended when using long-haul
mode (SHLHS4). Note that in order to use receive internal impedance termination, a 1:1 transformer must be used
and this bit must be set to 1.

Bit 6 to 4: Channel 4 Receive Sensitivity/Monitor Select [2:0] (C4RSM[2:0]).
When bits C4RSM[2:0] are used
to select the receiver sensitivity level and the monitor mode resistive gain. See
Table 6-17
.
Bit 3: Receiver Transformer Turns Ratio Channel 3(RTR3).
If this bit is set the Turns Ratio is 1:1 on the receiver
side. This bit should be set when a 1:1 receiver transformer is used and is recommended when using long-haul
mode (SHLHS3).
Bit 2 to 0: Channel 3 Receive Sensitivity/Monitor Select [2:0] (C3RSM[2:0]).
When bits C3RSM[2:0] are used
to select the receiver sensitivity level and the monitor mode resistive gain. See
Table 6-17
.

Bit 7: Receiver Transformer Turns Ratio Channel 12(RTR12).
If this bit is set the Turns Ratio is 1:1 on the
receiver side. This bit should be set when a 1:1 receiver transformer is used and is recommended when using long-
haul mode (SHLHS12). Note that in order to use receive internal impedance termination, a 1:1 transformer must be
used and this bit must be set to 1.
