Principle of Operation

The Peripheral Access Control module allows the user to set a write protection or security attribution on peripheral modules and generate an interrupt in case of a peripheral access violation. The peripheral’s protection can be set, cleared or locked at the user discretion. A set of Interrupt Flag and Status registers informs the user on the status of the violation in the peripherals. In addition, client bus errors can be also reported in the cases where reserved area is accessed by the application.
