Overview
The event system enables direct peripheral-to-peripheral communication and signaling. It allows a change in one
peripheral’s state to automatically trigger actions in other peripherals. It is designed to provide a predictable system for
short and predictable response times between peripherals. It allows for autonomous peripheral control and interaction
without the use of interrupts, and CPU, and is thus a powerful tool for reducing the complexity, size and execution time of
application code. It also allows for synchronized timing of actions in several peripheral modules.
A change in a peripheral’s state is referred to as an event, and usually corresponds to the peripheral’s interrupt
conditions. Events can be directly passed to other peripherals using a dedicated routing network called the event routing
network. How events are routed and used by the peripherals is configured in software.
Figure 8-1 on page 16 shows a basic diagram of all connected peripherals. The event system can directly connect
together analog to digital converter, analog comparators, I/O port pins, the real-time counter, timer/counters, IR
communication module (IRCOM), and USB interface. Events can also be generated from software and the peripheral
clock.

Event system overview and connected peripherals.
The event routing network consists of four software-configurable multiplexers that control how events are routed and
used. These are called event channels, and allow for up to four parallel event routing configurations. The maximum
routing latency is two peripheral clock cycles. The event system works in both active mode and idle sleep mode.
