Single Rail / Dual Rail Select Input
This pin is used to select Single Rail or Dual Rail data formats. By default,
Dual Rail is selected. To select Single Rail mode, this pin must be pulled
"High". Once this pin is pulled "High", TNEGn/CODEn can be used to select
between AMI and HDB3 Encoding/Decoding.

Termination Impedance Select
TERSEL[1:0] are used to set the internal impedance of the LIU for the Receive
and Transmit paths.
"00" = 75
for Tx and "High-Z" for Rx
"01" = 120
for Tx and "High-Z" for Rx
"10" = 75

Transmit Clock Data
"Low" = TPOS/TNEG data is sampled on the falling edge of TCLK
"High" = TPOS/TNEG data is sampled on the rising edge of TCLK
