The PDPINTx pin of F2812

The PWM pins are driven to a high-impedance state when the PDPINTx pin is driven low

so i'm wandering that when the pwm pins are in high-impedance status , how can i make the pwm pins into normal status, only restart? thank you

Normally, if you have an active PDPINT-pin you would request an interrupt service in parallel with the high-impedance state of the PWMs. You can then use the interrupt function to find out what happened and then to carefully try to re-initialize the output enable pins of the PWM-registers - or to keep the PWM's OFF because of a serious error.

Hope this helps.

thank you very much i think may be that's the only solution

i find that if reset the pdpinta flag(evaifra(0)) and set fcmope(comcona(9)), pwm will be in normal state again
