That's OK, I understand

> I'm not sure I fully follow your flow on using Comparators

The thought was to use a comparator to determine the state of the
CWG pins. As they are complementary the state of one will be
the inverse of the other.

For example, wire CWG1A to C1IN+. s/w detects C1IF, which
would be set when CWG1A goes high. PWM is turned on for the
duration of CWG1A=3Dhigh. CWG1A=3Dlow is detected via C1IF
after flipping the comparator polarity bit. The PWM when CWG1A
=3Dhigh comes out of one of the designated PWM pins. Another is
set to an I/O with the opposite polarity to CWG1A, corresponding
to CWG1B=3Dlow. When CWG1A=3Dlow, the opposite happens

You could get the same result by using IOC or polling to determine
the state of the CWG pins

There would be no or negligible effect on the audio

If you can't multiplex CWG with PWM inside the chip then you
can't get what you want on the CWG pins. Adding PWM to CWG
is a requirement Microchip seem not to have envisaged ;-) !!

All this comes with a disclaimer - I don't have a chip and could
easily have overlooked something but I think the two important
points are that CWG cannot be intercepted before the pins and
cannot be used as CLC input
