    Lawrence,

    Thanks for posting! I might need just a little more help understanding your question, so please let me know if my answer is not complete.

    The flag you're referencing is active when a wake-up occurs. If it is a LWU on the high-voltage input WAKE pin, then nFAULT will be LOW. Otherwise, nFAULT will be HIGH.
