Description
When set to 1 it enables the DAV/ADC_RDY pin output function.
When cleared to 0 the DAV/ADC_RDY pin is in high impedance
mode.
When cleared to 0 and if DAVPIN-EN is equal to 1 the
DAV/ADC_RDY pin operates as a DAV pin.
When set to 1 and if DAVPIN-EN is equal to 1 the
DAV/ADC_RDY pin operates as an ADC_RDY pin.
Reserved for factory use.
False alarm protection for ADC channels. Use the following
configurations for the consecutive samples before the alarm is
set:
000: 1
001: 4
010: 8
011: 16 (default)
100: 32
101: 64
110: 128
111: 256
When set to 1 enables PNP transistor configuration on both
remote temperature sensors.
When PAON_AVSS = 1 an AVSS alarm event automatically
switches the PA_ON pin to the OFF state.
The AVSS alarm must be cleared before the PA_ON pin can be
switch back to the ON state.
When PAON_AVSS = 0 the PA_ON pin is unaffected by an
AVSS alarm event.
False alarm protection for local temperature sensor. Use the
following configurations for the consecutive samples before the
alarm is set:
00: 1
01: 2
10: 4 (default)
11: 8
