Each generated peripheral event is connected to one or more users. If a peripheral event is con-
nected to multiple users, the peripheral event can trigger actions in multiple modules.
A peripheral event user can likewise be connected to one or more peripheral event generators. If
a peripheral event user is connected to multiple generators, the peripheral events are OR’ed
together to a single peripheral event. This means that peripheral events from either one of the
generators will result in a peripheral event to the user.
To configure a peripheral event, the peripheral event must be enabled at both the generator and
user side. Even if a generator is connected to multiple users, only the users with the peripheral
event enabled will trigger on the peripheral event.
As the peripheral events do not require CPU intervention, they are available in Idle mode. They
are also available in deeper sleep modes if both the generator and user remain clocked in that
mode.
Certain events are known as asynchronous peripheral events, as identified in
Table
user peripherals. The clock will be restarted for this module only, without waking the system from
sleep mode. The clock remains active only as long as required by the triggered function, before
being switched off again, and the system remains in the original sleep mode. The CPU and sys-
