Many 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 events are called users
and peripherals that emit events are called generators. A module may be both a generator and
user.
The peripheral event generators and users are interconnected by a network known as the
Peripheral Event System. The Peripheral Event Controller (PEVC) controls the interconnection
parameters, such as generator-to-user multiplexing and peripheral event enable/disable.
The Peripheral Event System allows low latency peripheral-to-peripheral signalling 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.
