32.6.6 Low-Pass Filter Mode

The Low-Pass Filter mode (MD = 100) acts similarly to the Average mode in how it handles samples (accumulates samples until the ADCNT value is greater than or equal to ADRPT, then triggers threshold comparison), but instead of a simple average, it performs a low-pass filter operation on all of the samples, reducing the effect of high-frequency noise on the average, then performs a threshold comparison on the results. In this mode, the CRS bits determine the cut-off frequency of the low-pass filter.
