10.2.3 Line I/O Pin Timing Source Selection
The line I/O pins can use any input clock pin (RLCLKn or TCLKIn) or output clock pin (TLCLKn, RCLKOn, or
TCLKOn) for its clock pin and meet the AC timing specifications as long as the clock signal is valid for the mode the
part is in. The clock select bit for the transmit line IO signal group PORT.CR3.TLTS selects the correct input or
output clock timing.
identifies the source of the output signal TCLKOn based on certain variables and register bits.
identifies the source of the output signal RCLKOn based on certain variables and register bits.
