Abstract
In one embodiment, an integrated circuit includes a pin and a current source for driving current through the pin into an external resistor such as a resistor on a circuit board to generate a pin voltage. The integrated circuit includes an analog-to-digital converter for converting the pin voltage into a digital value, such as an address for the integrated circuit.
