The Interface Control register enables alternative interfaces. All of these modes are
optional features provided for legacy link cores. Setting more than one of these fields
results in undefined behavior.

Description
Operation Mode: Selects the required bit-encoding style during transmit.
00b — Normal operation
01b — Non-driving
10b — Disable bit-stuffing and NRZI encoding
11b — Do not automatically add SYNC and EOP when transmitting; must be used only for
high-speed packets
Termination Select: Controls the internal 1.5 k full-speed pull-up resistor and 45
high-speed terminations. Control over bus resistors changes, depending on
XCVRSELECT[1:0], OPMODE[1:0], DP_PULLDOWN and DM_PULLDOWN, as shown in
Table
Transceiver Select: Selects the required transceiver speed.
00b — Enable the high-speed transceiver
01b — Enable the full-speed transceiver
10b — Enable the low-speed transceiver
11b — Enable the full-speed transceiver for low-speed packets (full-speed preamble is
automatically prefixed)
