I am working on outputing a PWM signal, and everytime I set up my initialization and enable the timer. The interrupt flags for channels 1,2 and 3 all get set and i am not sure why? even if i don't enable those 3 channels to have interrupts they are set high as soon as the timer is enabled. (using Timer1 and Timer 8)

Any suggestions?

This is a problem why? The update/zero event likely occurred, the CCRx match, there is a difference between this being flagged in the status bits, and whether an interrupted is actually masked and generating a physical interrupt.
