Register 0x6 allows the user to enable or disable any of the alarm flags that are not required. If disabled, that particular alarm no longer
flags on the appropriate open-drain pin; however, the alarm status is still available in both of the alarm status registers (Address 0x43 and
Address 0x44).

Bit Name Function
15 Latched
TMPALM
Set this latched bit high to program the open-drain
TMPALM
alarm pin as a latched output;
leave low for an unlatched alarm pin (default).
14
Disable
TMPALM
Set this bit high to disable the open-drain
TMPALM
alarm pin; leave low to leave enabled (default).
13 Latched
OSALM
Set this latched bit high to program the
OSALM
as a latched alarm on the open-drain
KELALM
pin; leave low for an unlatched alarm pin (default).
12 Disable
OSALM
Set this bit high to disable the
OSALM
alarm function flagging the open-drain
KELALM
pin;
leave low to remain enabled (default). The disable
GRDALM
,
DUTALM
, and
OSALM
alarm
functions share one open-drain
KELALM
alarm pin. These bits allow users to choose if they wish
to have all or selected information flagged to the alarm pin.
11 Latched
DUTALM
Set this latched bit high to program the
DUTALM
as a latched alarm on the open-drain
KELALM
pin; leave low for an unlatched alarm pin (default).
10 Disable
DUTALM
Set this bit high to disable the
DUTALM
alarm function flagging the open-drain
KELALM
pin.
Leave low to leave enabled (default). The disable
GRDALM
,
DUTALM
, and
OSALM
alarm
functions share one open drain
KELALM
alarm pin. These bits allow users to choose if they wish
to have all or any information flagged to the alarm pin. The DUTGND pin has a 50 µA pull-up to
allow for detection of an error in the DUTGND path. Setting this bit high also disables the 50 µA
pull-up.
9 Latched
CLALM
Set this latched bit high to program the open-drain
CLALM
clamp alarm pin as a latched
output; leave low for an unlatched alarm pin (default).
8 Disable
CLALM
Set this bit high to disable the open drain
CLALM
alarm pin; leave low to leave enabled (default).
7 Latched
GRDALM
Set this latched bit high to program the
GRDALM
as a latched alarm on the open-drain
KELALM
pin; leave low for an unlatched alarm pin (default).
6 Disable
GRDALM
Set this bit high to disable the
GRDALM
alarm function flagging the open-drain
KELALM
pin;
leave low to leave enabled (default). The disable
GRDALM
,
DUTALM
and
OSALM
alarm functions
share one open-drain
KELALM
alarm pin. These bits allow users to choose if they wish to have
all or any information flagged to the
KELALM
alarm pin.
