FAULT MONITORING SYSTEMS AND METHODS

Fault monitoring systems and methods presented herein perform steps comprising, in response to a host device receiving a valid command, if no fault condition is present in a circuit, communicating an acknowledgement response to the host device. Whether a fault condition is present in the circuit may be determined by a monitoring circuit. If a fault condition is found, an error acknowledgement response that is different from the acknowledgement response may be communicated to the host. Contrariwise, if an invalid command is received from the host, no acknowledgement response and no error acknowledgement response are communicated to reduce unnecessary communication.
