15.1 Overview

The Peripheral Access Controller (PAC) provides an interface for the locking and unlocking of peripheral registers within the device. It reports all violations which occur due to an improper access of a peripheral: write protected access, illegal access, enable protected access, or access when clock synchronization or software reset is on-going. These errors are reported with a unique interrupt flag for each peripheral. The PAC module also reports errors occurring at the client bus level, when an access to a non-existing address is detected.
