Detailed Description

Introduction

The event fabric consists of two event modules. One in the MCU power domain (MCU event fabric) and the other in the AON power domain (AON event fabric). The MCU event fabric is one of the subscribers to the AON event fabric. For more information on MCU event fabric, see MCU event API.

The AON event fabric is a configurable combinatorial router between AON event sources and event subscribers in both AON and MCU domains. The API to control the AON event fabric configuration can be grouped based on the event subscriber to configure:
