Hi Bryan,

The only case that I know is when I used an oscillator.  If you use a
crystal, that may be different.  You could check to see if the crystal is
inactive during programming mode by putting a frequency counter or an
oscilloscope on the clkin pin.  If it is active, I would think that you
would get the same poor results as I did, but maybe not.

Take care,
