Abstract
An integrated circuit has a single input pin for determining a value associated with a resistor divider. First circuitry determines 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 represents 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.
