Abstract
An integrated circuit includes first and second pads that are electrically connected to a circuit inside the integrated circuit. The circuit performs multiple functions which may be selected. A function identification circuit, inside the integrated circuit, is electrically connected to the first and second pads. The function identification circuit operates in multiple modes, wherein each operating mode corresponds to a function performed by the circuit. The function of the circuit may thereby be identified using fewer pads which may allow a reduction in the cost of the integrated circuit.
