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).

Name

Function

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).

Disable

TMPALM

Set this bit high to disable the open-drain TMPALM alarm pin; leave low to leave enabled (default).

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).

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.

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).

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.

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).

Disable

CLALM

Set this bit high to disable the open drain CLALM alarm pin; leave low to leave enabled (default).

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).

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.
