Hi Massimiliano, 

I believe you cannot access the RC1 & RC2 via PORTC when the compare module controls
the pin. There is also limitation on using two compares: "The compare(s) should be configured
for the special event trigger, which clears TMR1".

What do you need to achieve - a low frequency PWM on two pins? I cannot come up with
a strightforward solution right now, but it doesn't sound impossible.

Regards,

Josef
