Abstract: An integrated circuit (IC) includes a pin, a first passive component determination circuit, and a first switch having a first switch control input. The first switch is coupled between the first passive component determination circuit and the pin. The IC further includes a second passive component determination circuit and a second switch having a second switch control input. The second switch is coupled between the second passive component determination circuit and the pin. A logic circuit is coupled to first switch control input and to the second switch control input. The logic circuit is configured to close the first switch and open the second switch and then open the first switch and close the second switch.
