Virtual connections provide a simple way of inter-
peripheral connection without utilizing a physical pin.
For example, by setting the FLT1R<6:0> bits of the
RPINR12 register to the value of ‘b0000001, the
output of the Analog Comparator C1OUT will be
connected to the PWM Fault 1 input, which allows the
Analog Comparator to trigger PWM faults without the
use of an actual physical pin on the device.
