10.2.2 Sources of Clock Output Pin Signals
The clock output pins can be sourced from many clock sources. The clock sources are the transmit input clocks
pins (TCLKIn), the receive clock input pins (RLCLKn), and the clock signals in the clock rate adapter circuit
(CLAD). The default clock source for the receive logic is the RLCLKn pin. The default clock source for the transmit
logic is the CLAD clocks.
The bits LM, LBM[2:0], LOOPT and CLADC are located in the port configuration registers.

configured. Putting the device in loopback will typically mux in a different clock than the normal clock source.
