6.7 EGU — Event generator unit

The Event generator unit (EGU) provides support for inter-layer signaling. This means support for atomic

triggering of both CPU execution and hardware tasks from both firmware (by CPU) and hardware (by PPI).

This feature can, for instance, be used for triggering CPU execution at a lower priority execution from

a higher priority execution, or to handle a peripheral's ISR execution at a lower priority for some of its

events. However, triggering any priority from any priority is possible.

Listed here are the main EGU features:

• Enables SW triggering of interrupts

• Separate interrupt vectors for every EGU instance

• Up to 16 separate event flags per interrupt for multiplexing

Each instance of The EGU implements a set of tasks which can individually be triggered to generate the

corresponding event, i.e., the corresponding event for TASKS_TRIGGER[n] is EVENTS_TRIGGERED[n].

Refer to Instances on page 113 for a list of the various EGU instances
