Abstract

An integrated circuit chip is provided. The integrated circuit chip includes a pad, a first resistor, a second resistor, a first switch, a second switch and a controller. The first resistor and the first switch are serially connected between the pad and a first reference voltage terminal. The second resistor and the second switch are serially connected between the pad and a second reference voltage terminal. The controller selectively turns on and off the first and second switches according to an error determining mechanism. The error determining mechanism determines whether an error condition associated with the pad is present.
