1. A configurable interface circuit supporting selectable operational modes, including modes for analog measurement and analog output on a configurable channel, including a configurable drive circuit and a configurable measurement circuit, coupleable to at least one field device that is external to an integrated circuit, the interface circuit comprising:

  • the integrated circuit including;

    the configurable drive circuit including a current mode of operation, wherein a resistor is coupled to the configurable drive circuit and to the at least one field device that is external to the integrated circuit, the resistor to provide a current measurement element and a current control element; and

    the configurable measurement circuit coupled to the resistor and configured to monitor, using the resistor, a current forced through the configurable drive circuit, via the resistor, by the at least one field device.
