15.1 Overview

The Peripheral Access Controller provides an interface for the locking and unlocking and for managing security attribution of peripheral registers within the device. It reports all violations that could happen when accessing a peripheral: write protected register access, illegal access, enable protected register access, access when clock synchronization or software reset is on-going. These errors are reported in a unique interrupt flag for a peripheral. The PAC module also reports errors occurring at the client bus level, when an access to a non-existing address is detected.
