Description
Reserved for factory use
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.
This register selects which alarms can activate the ALARMOUT
pin. The ALARMOUT must be enabled for this function to take
effect.
