(internal) connections to the output of the comparator
modules CMP1OUT, CMP2OUT and CMP3OUT (see
Figure 25-1
In addition, dsPIC33EPXXXMU806/810/814 devices
support virtual connections to the filtered QEI module
inputs FINDX1, FHOME1, FINDX2 and FHOME2 (see

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 CMP1OUT 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.

enforced lockouts between any of the peripheral
mapping SFRs. Literally any combination of peripheral
mappings across any or all of the RPn/RPIn pins is
possible. This includes both many-to-one and one-to-
many mappings of peripheral inputs and outputs to
pins. While such mappings may be technically possible
from a configuration point of view, they may not be
supportable from an electrical point of view.
