I amusing the example program to run a single PWM and it works. All I am trying to do is run the CPU at a slower speed to conserve power. If I run it at 8Mhz with a pll setting of less the times 6 (so 48Mhz), the HRTIM will always timeout during calibration.

I have set the sysTick to give 1ms interrupts.

Is this a limitation of the HRTIM or is there something I can do?
