Abstract
In one aspect, an electronic device includes a switching circuit connected to a resistance circuit and ground, the resistance circuit connected to a port and the port configured to be connected in series to an external resistor and a supply voltage. A voltage at the port is a first voltage that is less than the supply voltage if the switching circuit is enabled to be a closed circuit and the voltage at the port is a second voltage that is equal to the supply voltage if the switching circuit is enabled to be an open circuit.
