G18 118 –

I/O General-purpose input/output 133. The AUXCLKIN

function of this GPIO pin could be used to provide a

single-ended 3.3-V level clock signal to the Auxiliary

Phase-Locked Loop (AUXPLL), whose output is used for

the USB module. The AUXCLKIN clock may also be

used for the CAN module.
