    Default 10 bit HPWM at 32767 Hz

    Hi Darrel & Charles.

    I need 50% duty cycle at 32767 Hz on CCP2 to drive an Intersema pressure sensor - easy - even I can do that with 8 bit HPWM.

    I also need a variable duty cycle to drive an AGC circuit. With 8 bit HPWM, my AGC is sudden death and one count goes from not quite enough to a little bit too much. 10 bit HPWM would be much less sensitive. The frequency must stay at 32767 Hz to suit the Intersema sensor.

    Can I get 10 bit HPWM at 32767 Hz?

    Cheers
    Brian
