• Bits 2:0 - EVACT[2:0]: ADC Event Mode
These bits define how many of the selected event channel that are in use, and also some spe-
cial event modes as defined in
sweep triggered by a single event, or an event re-synchronized conversion to achieve a very
accurate timing for the conversion.

EVSEL
One sweep of all active ADC channels defined by SWEEP on
incoming event channel with the lowest number, defined by
EVSEL. In addition, the conversion will be synchronized on
event to ensure a very accurate timing for the conversion.
