24.2 Overview

The Event System (EVSYS) enables autonomous, low-latency, and configurable communication between peripherals.

Several peripherals can be configured to generate and/or respond to signals known as events. The exact condition for generating an event, or the action taken upon receiving an event, is specific to each peripheral. Peripherals that respond to events are called event users, while peripherals that generate events are called event generators. A peripheral can have one or more event generators and one or more event users.

Communication is performed without CPU intervention and without consuming system resources such as bus or SRAM bandwidth. This reduces the load on the CPU and other system resources compared to a traditional interrupt-based system.
