  • Output Stage Circuit Apparatus for a Processor Device and Method Therefor
    Publication number: 20080209169
    Abstract: A drive circuit arrangement for a processor device comprises a non-volatile register for recording the identities of outputs of the processor device at which a same output signal is required. Configuration circuitry employs dual pairs of switching devices to couple register locations associated with a predetermined output of the processor to buffers of outputs identified in the non-volatile register, thereby resulting in a same output signal being provided at the identified outputs as at the predetermined output.
