Receiver Termination Select:
Upon power up, the receivers are in “High” impedance. The LIU pro-
vides an option for user to have either software or hardware control
over receive termination. If RxTCNTL (bit 6 in Register 0x0FE2) is
set to’0’, receive termination can be selected by programming this
register bit. To switch control to the hardware pin (RxTSEL pin),
RxTCNTL must be programmed to “1”. Once control has been
granted to the hardware pin, RxTSEL must be pulled “High” to
switch to internal termination.
If RxTCNTL is set to’0’, receive termination can be selected by set-
ting this bit according to the following table:

Transmit Termination Select:
This bit is used to select between internal termination or “High”
impedance modes for the T1 transmitter according to the following
table:

Termination Impedance Select [1:0]:
These bits are used to control the transmit and receive termination
impedance when the LIU block is configured in Internal Termination
Mode.
In internal termination mode, (i.e., TXTSEL = “1” and RXTSEL =
“1”), internal transmit and receive termination can be selected
according to the following table:
NOTE:
In the internal termination mode, the transmitter output
should be AC coupled to the transformer.
