So I am trying to integrate the ETPU PWM (from set1) into a basic structure to set a new duty cycle with an EMIOS mod counter. However, whenever I run the initialization function fs_etpu_init (which is included in the MPC55XX cookbook) an interrupt is generated continuously, nothing else can function. Specifically, it is the interrupt that corresponds to the Loss of Lock. However, I have disabled this option in the PLL config and when I monitor the PLL register it doesn't lose lock.
I am using the MPC5553 with CodeWarrior 5.9. Any help would be appreciated.
