Receive Termination Select
Upon power up, the receiver is in "High" impedance. RxTSEL is
used to switch between the internal termination and "High" imped-
ance.
0 = "High" Impedance
1 = Internal Termination
Transmit Termination Select
Upon power up, the transmitter is in "High" impedance. TxTSEL is
used to switch between the internal termination and "High" imped-
ance.
0 = "High" Impedance
1 = Internal Termination

Receive Line Impedance Select
TERSEL is used to select the line impedance for E1.
"0" = 75 
"1" = 120 
Jitter Attenuator Select
JASEL[1:0] are used to select the jitter attenuator in the transmit or
receive path. By default, the jitter attenuator is disabled.
