Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Read-only, indicates the number of '1' bits in ALARMSTOP register.
The maximum value equals the number of FROs.
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Threshold setting for generating IRQFLAGSTAT.SHUTDOWN_OVF
interrupt. The interrupt is triggered when SHUTDOWN_CNT value
exceeds this bit field.
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Alarm detection threshold for the repeating pattern detectors on each
FRO. An FRO 'alarm event' is declared when a repeating pattern (of
up to four samples length) is detected continuously for the number of
samples defined by this field's value. Reset value 0xFF must keep
the number of 'alarm events' to a manageable level.
