AD0BUSY: ADC0 Conversion In-Progress Flag.
0: ADC0 is not performing conversions.
1: ADC0 conversion in progress.
AD0CBSY: ADC0 Calibration In-Progress Flag.
0: ADC0 is not performing a calibration.
1: ADC0 calibration in progress.
AD0INT: ADC0 Conversion Complete Interrupt Flag.
This flag must be cleared in software.
0: ADC0 has not completed a conversion since the last time this flag was cleared.
1: ADC0 conversion is complete.
AD0S3C: ADC0 SINC3 Filter Clip Flag.
This error flag indicates that a clip has occurred in the SINC3 filter during the conversion
process.
0: ADC0 SINC3 filter clip did not occur.
1: ADC0 SINC3 filter clip occurred during conversion.
AD0FFC: ADC0 Fast Filter Clip Flag.
This error flag indicates that a clip has occurred in the fast filter during the conversion pro-
cess.
0: ADC0 fast filter clip did not occur.
1: ADC0 fast filter clip occurred during conversion.
AD0CALC: ADC0 Calibration Complete Flag.
0: ADC0 calibration not complete.
1: ADC0 calibration complete.
AD0ERR: ADC0 Error Flag
This bit is set by hardware under the following conditions:
1) A conversion cycle produced an AD0OVR, AD0S3C, or AD0FFC error.
2) A calibration cycle produced a result that is beyond the limits of the offset or gain
register.
0: ADC0 error did not occur.
1: ADC0 error occurred.
AD0OVR: ADC0 Overrun Flag
This error flag indicates an overrun condition.
0: ADC0 Overrun did not occur.
1: ADC0 Overrun occurred.
