在c code:
void __attribute__((__interrupt__, auto_psv, context)) _ADCAN13Interrupt(void)
{
c2p2z_buck_Update(&c2p2z_buck); //call the compensator as soon as possible
// the readout of the ADC register is mandatory to make the reset of the interrupt flag stick
// if we would not read from the ADC register then the interrupt flag would be set immediately after resetting it

// Triggering AD conversion for Vin
ADCON3Lbits.SWCTRG = 1; // Single trigger is generated, this bit it is automatically cleared by
// hardware on the next instruction cycle

pwrCtrlBuck1_Data.voltageOutput = ADCBUF13;
pwrCtrlBuck1_Data.flags.bits.adc_active = true;

_ADCAN13IF = 0; // Clear the ADCANx interrupt flag. read from ADCBUFx first to make it stick

//TODO: discuss, if we should call the buck_Update routine at first or after resetting the interrupt flag?
}
並沒有找到pwm duty 的地方?
輸出'pwm是PG1DC?
volatile uint16_t Drv_PowerControllerBuck1_InitPWM(void)
{
...
PG1DC = MAX_DUTY_CYCLE;
...
}
