Transmit ON/OFF
Upon power up, the transmitters are powered off. This bit is used
to turn the transmitter for this channel On or Off.
0 = Transmitter is Powered OFF
1 = Transmitter is Powered ON
Loopback Diagnostic Select
LOOP[2:0] are used to select the loopback mode.
0XX = No Loopback
100 = Dual Loopback
101 = Analog Loopback
110 = Remote Loopback
111 = Digital Loopback
This Register Bit is Not Used.
Encoding/Decoding Select (Single Rail Mode Only)
0 = HDB3
1 = AMI Coding
Receive External Fixed Resistor
RxRES[1:0] are used to select the value for a high precision exter-
nal resistor to improve return loss.
00 = None
01 = 320 
10 = 280 
11 = 190 
Insert Bipolar Violation
When this bit transitions from a "0" to a "1", a bipolar violation will
be inserted in the transmitted QRSS/PRBS pattern. The state of
this bit will be sampled on the rising edge of TCLK. To ensure
proper operation, it is recommended to write a "0" to this bit before
writing a "1".
