The AC has one event user for detecting and acting upon input events. The table below describes the event user and the associated functionality.

Table 30-2. AC Event Users and Available Event Actions
User Name		Description	Input Detection	Async/Sync
Peripheral	Input	Description	Input Detection	Async/Sync

The AC can be configured to sample the inputs on the rising edge of an event signal by selecting the Event Triggered operating mode, which is done by configuring the Operation Select (OPSEL) bitfield in the Control A (ACn.CTRLA) register.

Refer to the EVSYS - Event System section for more information on event types and how to configure the Event System.
