Re: Discrepancy of timing during debugging versus non-debugging

2006-02-21 by Jeff Davis

I do have PLL code (which does work when enabled), but I've been
running most all of the debugging with the PLL disabled (removing
calls to config PLL with "#ifdef USE_PLL") because of this problem. 
So this problem actually crops up while running with straight crystal
speeds (12.288MHz).
