An integrated circuit including a single input pin for determining a value associated with a resistor divider. The circuit includes first circuitry for determining a resistor ratio of the resistor divider through the single input pin. A first register stores a first group of bits representing the resistor ratio. The first group of bits comprises the least significant bits of the value. Second circuitry determines an equivalent resistance of the resistor divider through the single input pin. A second register stores a second group of bits representing the equivalent resistance. The second group of bits comprises the most significant bits of the value associated with the resistor divider.
