Table 25. Alarm Status and Clear Alarm Status Register
Address Register Default Data Bits, MSB first
0x43 Alarm status 0x0000 This register is a read-only register providing information on the status of the alarm functions and
the comparator outputs.
Bit Name Function
15
LTMPALM
Latched temperature alarm bit; if low, this bit indicates that an alarm event has
occurred.
14
TMPALM
Unlatched alarm bit; if low, these bit indicates that an alarm event is still
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.
9
LCLALM
Latched clamp alarm; if low, indicates that an alarm event has occurred.
8
CLALM
Unlatched clamp alarm; if low, indicates that an alarm event is still present.
7
LGRDALM
Latched guard alarm; if low, indicates that an alarm event has occurred.
6
GRDALM
Unlatched guard alarm; if low, indicates that an alarm event is still present.
5 CPOL Comparator output low condition as per the comparator output pin.
4 CPOH Comparator output high condition as per the comparator output pin.
3:0 Unused Must be zeros.
0x44 Alarm status
and clear alarm
0x0000 This register is a read-only register providing information on the status of the alarm functions and
the comparator outputs. Reading this register also automatically clears any latched alarm pins or bits.
