33.5.2.4 Event System Channel
An event channel can select one event from a list of event generators. Depending on configuration, the selected event could be synchronized, resynchronized or asynchronously sent to the users. When synchronization or resynchronization is required, the channel includes an internal edge detector, allowing the Event System to generate internal events when rising, falling or both edges are detected on the selected event generator.
An event channel is able to generate internal events for the specific software commands. A channel block diagram is shown in Block Diagram section.
