For applications supporting the PMBus power system protocol specification, the SYSMON adds the SMBALERT output as described in the PMBus specification. This optional pin provides an interrupt output and supports alert response address (ARA) functionality as defined by the PMBus specification.

Important: The SMBALERT continues to be asserted while the failing condition exists.
