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.
