Receiver Termination Select: In Host mode, this bit is used
to select between the internal and external line termination
modes for the receiver according to the following table;
Transmit Termination Select: In Host mode, this bit is used
to select between the internal and external line termination
modes for the transmitter according to the following table;
In Host mode and in internal termination mode, (TXTSEL = “1”
and RXTSEL = “1”) TERSEL[1:0] control the transmit and
receive termination impedance according to the following
table;
In the internal termination mode, the receiver termination of
each receiver is realized completely by internal resistors or by
the combination of internal and one fixed external resistor.
In the internal termination mode, the transmitter output should
be AC coupled to the transformer.
