TCLK: Transmit Clock (Input)
A 2.048/8.192 MHz clock has to be sourced by the system if the internal generated transmit
clock (DCO-X) is not used. Optionally this input is used as a synchronization clock for the
DCO-X circuitry with a frequency of 2.048 MHz.

XCLK: Transmit Line Clock (Output)
Frequency: 2.048 MHz
XLT: Transmit Line Tristate control input, high active
With a high level on this port the transmit lines XL1/2 or XDOP/N are set directly into tristate.
This pin function is logically OR´d with register XPM2.XLT. See
GPI: General Purpose Input, low level
Value of this input is stored in register MFPI.
GPOH: General Purpose Output, high level
Pin is set fixed to high level
GPOL: General Purpose Output, low level
Pin is set fixed to low level

XDIN: Transmit Data In Negative
Negative transmit data in for dual rail mode
XLT: Transmit Line Tristate control input, low active
See XLT
