Hi All,
I was hoping you might be able to help me. I have a project that is using a
PIC16LF876. It is intended to run on 3.3V but I can't get it to do so. It
runs fine at 5V. The problem seems to be the oscillator, I have looked at the
OSC pins with a CRO and it doesn't appear to be oscillating when powered
from 3.3V. I have tried a 4Mhz resonator and a 4Mhz crystal with the
associated capacitors of various values from 10pF to 22pF and also tried
adding a resistor like it says in the reference manual. I have the config
set to the XT mode. Does anyone have any tips for making the thing
oscillate at 3.3V?

Wesley
