Abstract

An addressable circuit configured to control a definition of an addressable range for the circuit. The circuit may comprise at least one register, at east one flag, an input and control logic. The register may be configured to define a range used for determining an addressable range for the circuit. The flag may be configured to define whether a predetermined range is to be inverted for determining the addressable range for the circuit. The input may be configured to receive an address for an access to the circuit. The control logic may be configured to process the received address to determine whether the received address is within the addressable range for the circuit, the control logic being responsive to the register and to the flag for determining the addressable range therefrom.
