Event Channels

The Peripheral Event Controller module in the SAM4L device consists of several channels, which can be freely linked to an Event Generator (i.e. a peripheral within the device that is capable of generating events). Each channel can be individually configured to select the generator peripheral, signal path, Event Shaper (EVS), and Input Glitch Filter (IGF) applied to the input event signal, before being passed to any event user(s).

Event Channels can support multiple users within the device in a standardized manner; when an Event User is linked to an Event Channel, the channel will automatically handshake with all attached users to ensure that all modules correctly receive and acknowledge the event.
