External Ocilator PIC16f690 Help

[Gusse]

I connected a 20mhz cystal to OSCL1 and OSCL2 with 22uF ceramic caps but that did not drop the frequency of a HPWM signal.

I hope this is just a typo, right capacitor range is in pF.

Gusse is right. I thought it is something like 12pf needed for 20 Mhz crystal. Why not just slap in a 20 Mhz resonator with the capacitor built in.

Nice catch !
