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). --- In lpc2000@yahoogroups.com, "Danish Ali" <danish@...> wrote: > > If you single-step through the setup routine for the PLL, it is possible that this > kills the PLL feed sequence and you'll probably be running at the crystal frequency. > > I haven't tried this, but it's what I would expect.
