Abstract
Access permissions are set for different requesting circuits on a control bus. The access permissions can be set by the level 1 manager and the level 2 manager, allowing two layers of security to be added. The level 1 manager has priority, allowing it to add access permissions that cannot be removed by the level 2 manager.
