Abstract:
1. A method for determining a setting specified from a plurality of the settings for a function provided in an integrated circuit, wherein the setting is specified by connecting an external measurement resistor to a measurement terminal of the integrated circuit, the method comprising: applying a direct current to the measurement terminal of the integrated circuit, thereby producing a measurement voltage at the measurement terminal; applying the direct current to a reference terminal of the integrated circuit, wherein the reference terminal has an external reference resistor connected thereto, thereby producing a reference voltage at the reference terminal; quantizing a voltage level of a difference voltage representing a voltage difference between the reference voltage and the measurement voltage, thereby producing a quantized voltage; and providing control signals to a functional module within the integrated circuit, the control signals representing the one of the settings corresponding to the quantized voltage, wherein each of the settings is represented by a different quantized voltage; wherein the functional module implements the one of the settings represented by the control signals.
