Bit 7: Receiver Transformer Turns Ratio Channel 2 (RTR2). 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 2 Receive Sensitivity/Monitor Select [2:0] (C2RSM[2:0]). Bits C2RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See
Bit 3: Receiver Transformer Turns Ratio Channel 1 (RTR1). 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 1 Receive Sensitivity/Monitor Select [2:0] (C1RSM[2:0]). Bits C1RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See

Bit 7: Receiver Transformer Turns Ratio Channel 10 (RTR10). 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 10 Receive Sensitivity/Monitor Select [2:0] (C10RSM[2:0]). Bits C10RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See
Bit 3: Receiver Transformer Turns Ratio Channel 9 (RTR9). 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 9 Receive Sensitivity/Monitor Select [2:0] (C9RSM[2:0]). Bits C9RSM[2:0] are used to
select the receiver sensitivity level and the monitor mode resistive gain. See
