With SC2[ACREN] =1, and if the value of CV1 is less than or equal to the value of CV2,
then setting SC2[ACFGT] will select a trigger-if-inside-compare-range inclusive-of-
endpoints function. Clearing SC2[ACFGT] will select a trigger-if-outside-compare-
range, not-inclusive-of-endpoints function.

If CV1 is greater than CV2, setting SC2[ACFGT] will select a trigger-if-outside-
compare-range, inclusive-of-endpoints function. Clearing SC2[ACFGT] will select a
trigger-if-inside-compare-range, not-inclusive-of-endpoints function.

If the condition selected evaluates true, SC1n[COCO] is set.

Upon completion of a conversion while the compare function is enabled, if the compare
condition is not true, SC1n[COCO] is not set and the conversion result data will not be
transferred to the result register, Rn. If the hardware averaging function is enabled, the
compare function compares the averaged result to the compare values. The same compare
function definitions apply. An ADC interrupt is generated when SC1n[COCO] is set and
the respective ADC interrupt is enabled, that is, SC1n[AIEN]=1.

Note

The compare function can monitor the voltage on a channel
while the MCU is in Wait or Normal Stop modes. The ADC
interrupt wakes the MCU when the compare condition is met.

24.5.6 Calibration function

The ADC contains a self-calibration function that is required to achieve the specified
accuracy.

Calibration must be run, or valid calibration values written, after any reset and before a
conversion is initiated. The calibration function sets the offset calibration value, the
minus-side calibration values, and the plus-side calibration values. The offset calibration
value is automatically stored in the ADC offset correction register (OFS), and the plus-
side and minus-side calibration values are automatically stored in the ADC plus-side and
minus-side calibration registers, CLPx and CLMx. The user must configure the ADC
correctly prior to calibration, and must generate the plus-side and minus-side gain
calibration results and store them in the ADC plus-side gain register (PG) after the
calibration function completes.

Prior to calibration, the user must configure the ADC's clock source and frequency, low
power configuration, voltage reference selection, sample time, and high speed
configuration according to the application's clock source availability and needs. If the
