INT[6]
RTC Match Rising Edge – If 1, the RTCMATCH output has transitioned high, indicating that the RTC
has reached the desired count.
5
INT[5]
ACM Read Done – If 1, an ACM read cycle has completed and valid data can be read from the
ACM DATA register.
4
INT[4]
ACM Write Done – If 1, an ACM write cycle has completed and valid data has been written into the
AB macro.
3
INT[3]
DATAVALID Rising Edge – If 1, the DATAVALID signal from the AB block has transitioned high,
indicating that valid converted data from the ADC is available on the RESULT[11:0] output port
from the AB block.
2
INT[2]
BUSY Rising Edge – If 1, the BUSY signal from the AB block has transitioned high, indicating that
the ADC has begun an analog-to-digital conversion and is now busy performing that conversion.
1
INT[1]
CALIBRATE Falling Edge – If 1, the CALIBRATE signal from the AB block has transitioned low,
indicating that the ADC has finished its calibration procedure.
0
INT[0]
CALIBRATE Rising Edge – If 1, the CALIBRATE signal from the AB block has transitioned high,
indicating that the ADC has started its calibration procedure.
