прерывание pwm dspic30f2023 Опции

[pipka]

Здравствуйте, помогите разобраться почему не срабатывает прерывание ШИМ.

код(MPLAB C30):


#include <p30f2023.h>
#include "functions.h"


_FOSCSEL(FRC_PLL); //FRC with PLL
_FOSC(CSW_FSCM_OFF & FRC_HI_RANGE & OSC2_IO & HS_EC_DIS); //Clock switching is disabled,FCKSM is disabled
_FWDT(FWDTEN_OFF); //Watchdog timer off
_FPOR(PWRT_OFF); //Power-on Reset
_FICD(ICS_PGD);

int main(void)
{
init();
while(1)
{

}

}
