Response
Do nothing.
Continue operation for the time specified by Delay Time 1 (Bits[2:0]). If the fault
persists, retry the number of times specified by the retry setting (Bits[5:3]).
Shut down, disable the output, and retry the number of times specified by the
retry setting (Bits[5:3]).
Disable the output and wait for the fault to clear. After the fault is cleared,
reenable the output.
