present.
13
LOSALM
Latched open-sense alarm bit; if low, indicates that an alarm event has
occurred.
12
OSALM
Unlatched open-sense alarm bit; if low, indicates that an alarm event is still
present.
11
LDUTALM
Latched DUTGND Kelvin sense alarm; if low, indicates that an alarm event has
occurred.
10
DUTALM
Unlatched DUTGND Kelvin sense alarm; if low, indicates that an alarm event is still
present.
