PWM Overflow Interrupt
I have set up a PWM module running at 40khz, and wired the interrupt output to an ISR as shown in the attached file.
The problem is that execution nevert reaches the interrupt handler...
I have called the initialisation functions for the PWM module and I know that the PWM is up and running fine. I have also called <ISR>_Start() which internally calls <ISR>_Enable... Did a single step debug to ensure that these functions are indeed called. The PWM is working fine since I have checked it on a 'scope. Cant figure out what I'm missing... Also, what is to be expected if I tie the Interrupt output of the PWM Block to a digital output pin?
