Description
15:8
RFU
reserved; always 0
7
DisableTimeout   Disable SMBus time-out.
0  SMBus time-out is enabled (default)
1  SMBus time-out is disabled
When either of the Critical Trip or Alarm Window lock bits is set, this bit
cannot be altered until unlocked.
6
RFU
reserved; always 0
5
EnableSDTO
SMBus time-out during Shutdown (CONFIG[8]).
0  disable SMBus time-out
1  enable SMBus time-out (default)
Remark: DisableTimeout bit must be a logic 0 to enable this feature.
When either Critical Trip or Alarm Window lock bits are set, this bit
cannot be altered until unlocked.
4
EventSleep
State
[1]
State of EVENT
 output when SHMD bit is set.
0  EVENT
 pin state is frozen
1  EVENT
 pin is de-asserted, state based on Polarity bit (default)
When either Critical Trip or Alarm Window lock bits are set, this bit
cannot be altered until unlocked.
3
IntrClear
Mode
[2]
Interrupt Flop Clearing Mode.
0  allow clearing interrupt flop while in comparator mode (default)
1  disable clearing interrupt flow while in comparator mode
When either Critical Trip or Alarm Window lock bits are set, this bit
cannot be altered until unlocked.
2
FlagUpdate
Mode
Update AAW, BAW and ACT flags after each new temperature
conversion.
0  update AAW, BAW and ACT flags continuously (default)
1  update flags with new temperature conversion
When either Critical Trip or Alarm Window lock bits are set, this bit
cannot be altered until unlocked.
