Abstract
An integrated circuit, such as for example an application specific integrated circuit, as well as a method of testing such a circuit, are disclosed herein. In one example embodiment, the integrated circuit includes a plurality of pins including a power pin, a ground pin, and a first communication pin, a test mode circuit, and a communication circuit. The integrated circuit additionally includes a first switch connected to the first communication pin, where the first switch is configured to couple the first communication pin to either the test mode circuit or the communication circuit. The integrated circuit further includes a control circuit coupled to the first switch and configured to control whether the first switch is operated to couple the first communication pin to the test mode circuit or to the communication circuit based upon or in response to an operating mode.
