Several peripheral modules can be configured to emit or respond to signals known as peripheral
events. The exact condition to trigger a peripheral event, or the action taken upon receiving a
peripheral event, is specific to each module. Peripherals that respond to peripheral events are
called peripheral event users and peripherals that emit peripheral events are called peripheral
event generators. A single module can be both a peripheral event generator and user.
The peripheral event generators and users are interconnected by a network known as the
Peripheral Event System. This allows low latency peripheral-to-peripheral signaling without CPU
intervention, and without consuming system resources such as bus or RAM bandwidth. This
offloads the CPU and system resources compared to a traditional interrupt-based software
driven system.
The Peripheral Event System in the AT32UC3L has a fixed mapping of peripheral events
between generators and users, as described in
not need to configure the interconnection between the modules, although each peripheral event
can be enabled or disabled at the generator or user side as described in the peripheral chapter
for each module.
Direct peripheral to peripheral communication system
Allows peripherals to receive, react to, and send peripheral events without CPU intervention
Cycle deterministic event communication
Asynchronous interrupts allow advanced peripheral operation in low power sleep modes
