Abstract: Techniques for implementing a self-test procedure of an integrated circuit are provided, where the self-test procedure comprises testing for an electrical connection between first and second input-output pads of the integrated circuit. A control device is capable of adapting a functional configuration of usage of the first and second input-output pads in dependence on presence of the electrical connection. A corresponding integrated circuit, printed circuit and method are also provided. These techniques allow the integrated circuit to be used in a variety of contexts, without requiring physical customisation of the integrated circuit to adapt it to its usage context, in particular where connections from the context to the pads of the integrated circuit may be made to individual pads in some contexts or may span more than one pad in other contexts.

Abstract: An electronic device 50 has at least one harvesting unit 52 for harvesting power from ambient energy. At least one circuit 54, including processing circuitry 56, is supplied with power from the harvesting unit 52. Control circuitry 60 is provided to adjust at least one property of the processing circuitry 56 or the at least one harvesting unit 52 to reduce impedance mismatch between an output impedance of the harvesting unit 52 and an input impedance of the at least one circuit 54.
