Abstract: An integrated circuit comprises first and second interfaces, an internal addressable space comprising a plurality of address ranges, and a control unit. Each of the first and second interfaces is coupled to the internal addressable space via the control unit. The control unit is configurable in a first state in which the control unit is configured to allow or deny the second interface access to a subset of the plurality of address ranges of the internal addressable space.
