ALARM-LATCH-DIS

R/W

Alarm latch disable bit.

When cleared to 0 the alarm bits are latched. When an alarm

occurs, the corresponding alarm bit is set to “1”. The alarm bit

remains until the error condition subsides and the alarm register

is read. Before reading, the alarm bit is not cleared even if the

alarm condition disappears. When set to 1 the alarm bits are not

latched. When the alarm condition subsides, the alarm bits are

cleared regardless of whether the alarm bits have been read or

not.

ALRIN-ALR-OUT

R/W

This register selects which alarms can activate the ALARMOUT

pin. The ALARMOUT must be enabled for this function to take

effect.
