Help with multiple SPWM

[retepsnikrep]

I have the below program and want it to generate the following pwm signals.

1) 2khz HPWM this is working fine as shown by scope.
2) 25hz 50% duty SPWM this is working fine as shown by scope.
3) 25hz 7% duty SPWM this is not working correctly and is broken up and irregular.
4) 12hz Manual pause defined PWM, again this is not working correctly and the led I have to check the loop is not working
The loop1 is is not executing for some reason.

Perhaps something in my config/register setup?

It uses Darrells Instant interrupts and SPWM but I can't see anything obviously wrong. Can you?

Your 25 Hz 50% signal won’t be accurate either because it’s not evenly divisible by your instruction time 16/4 = 4 MHz.
Only the 2kHz 50% signal can be free of resolution error with the 16 MHz clock.

I've managed to fix it, appears I had not disabled the Adc and the analog inputs and they were somehow causing issues.
