Hi i have an issue that i have tracked to this code:

interrupt void ADCScalingInt(void)
{
// unsigned int chan_a_1v5=0;
Int32 i,j,tempOff0A=0,tempOff0B=0,tempOff0C=0,tempOff0D=0;

while (AdcResult.ADCRESULT1== 0)
{
PieCtrlRegs.PIEIFR3.bit.INTx1=0;
//AdcRegs.ADCTRL.bit.RST_SEQ1=1;
}

for (i=0;i<1024;i++)
{
tempOff0A +=1;//AdcResult.ADCRESULT0>>4;
tempOff0C +=11;//AdcResult.ADCRESULT1>>4;
//AdcRegs.ADCTRL2.bit.SOC_SEQ1=1;
for (j=0;j<1;j++) DELAY;
}

CurrLoop.ADCOffset_Phase_A=tempOff0A>>6;
CurrLoop.ADCOffset_Phase_C=tempOff0C>>6;
CurrLoop.IaOff=(Int32)CurrLoop.ADCOffset_Phase_A + ((UInt32)1<<15);
CurrLoop.IcOff=(Int32)CurrLoop.ADCOffset_Phase_C + ((UInt32)1<<15);

}
