The Event System is a set of features for inter peripheral communication. It enables the possibil-
ity for a change of state in one peripheral to automatically trigger actions in other peripherals.
The change of state in a peripheral that will trigger actions in other peripherals is configurable in
software. It is a simple, but powerful system as it allows for autonomous control of peripherals
without any use of interrupt, CPU or DMA resources.
The indication of a change of state in a peripheral is referred to as an event. The events are
passed between peripherals using a dedicated routing network called the Event Routing Net-
work.
Routing Network and the peripherals that are connected.
Inter peripheral communication and signalling
CPU and DMA independent operation
8 Event Channels allows for up to 8 signals to be routed at the same time
100% predictable timing between peripherals
Events can be generated by
