This register controls access to various Peripherals depending on the privilege setting. By default, all slaves will be assumed as Privileged. To allow non-Privileged access to a slave, the corresponding bit for the slave must be set. Once set, both Privilege and non-Privileged transactions are allowed to the Slave. Note that the privilege filter only checks for transaction Privilege level, transaction Security is left to Firewalls. Firewalls therefore may still block transaction to Peripherals depending on Security configurations.
