Abstract: Circuitry, systems, and methods for fault detection and reporting comprise a fault detection circuit configured to detect one or more fault conditions that cause a state change in a fault pin voltage representative of a transceiver failure. Once the state of the fault pin voltage changes, a transceiver input generates a fault detection code. In embodiments, in response to the transceiver input receiving a first signal, the fault detection code is shifted to a transceiver output that may communicate the fault detection code to a controller. Once the transceiver input receives a second signal, the fault pin voltage may be reset to clear the fault detection code before resuming operations, including detecting additional fault conditions as they arise.
