Bit 7: Receiver Transformer Turns Ratio Channel 6 (RTR6). 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. Note that in order to use fully internal receive
impedance termination, a 1:1 transformer must be used and this bit must be set to 1.
Bits 6 to 4: Channel 6 Receive Sensitivity/Monitor Select [2:0] (C6RSM[2:0]). Bits C6RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See
Bit 3: Receiver Transformer Turns Ratio Channel 5 (RTR5). 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. Note that in order to use the fully internal
receive impedance termination, a 1:1 transformer must be used and this bit must be set to 1.
Bits 2 to 0: Channel 5 Receive Sensitivity/Monitor Select [2:0] (C5RSM[2:0]). Bits C5RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See

Bit 7: Receiver Transformer Turns Ratio Channel 14 (RTR14). 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. Note that in order to use fully internal
receive impedance termination, a 1:1 transformer must be used and this bit must be set to 1.
Bits 6 to 4: Channel 14 Receive Sensitivity/Monitor Select [2:0] (C14RSM[2:0]). Bits C14RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See
Bit 3: Receiver Transformer Turns Ratio Channel 13 (RTR13). 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. Note that in order to use the fully
internal receive impedance termination, a 1:1 transformer must be used and this bit must be set to 1.
Bits 2 to 0: Channel 13 Receive Sensitivity/Monitor Select [2:0] (C13RSM[2:0]). Bits C13RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See
