A fault sensing circuit for detecting the state of at least one latch controlled by at least one control signal is provided. The circuit comprises an additional latch also controlled by the same control signal and receiving an input of a known value. The output of the additional latch is coupled to an I/O pin where an external circuit may monitor its logic state to determine the occurrence of a fault.
