CONFIGURATION REGISTER
This 8-bit read/write register stores various configuration modes
for the ADT7310, including shutdown, overtemperature and
undertemperature interrupts, one-shot, continuous conversion,
interrupt pins polarity, and overtemperature fault queues.

Description
[1:0]
00
R/
W
     Fault queue
These two bits set the number of undertemperature/overtemperature faults that can
occur before setting the INT and CT pins. This helps to avoid false triggering due to
temperature noise.
 
 
 
 
00 = 1 fault (default).
 
 
 
 
01 = 2 faults.
 
 
 
 
10 = 3 faults.
 
 
 
 
11 = 4 faults.
2
0
R/W
     CT pin polarity
This bit selects the output polarity of the CT pin.
 
 
 
 
0 = active low.
 
 
 
 
1 = active high.
3
0
R/W
     INT pin polarity     This bit selects the output polarity of the INT pin.
 
 
 
 
0 = active low.
 
 
 
 
1 = active high.
4
0
R/W
     INT/CT mode
This bit selects between comparator mode and interrupt mode.
 
 
 
 
0 = interrupt mode.
 
 
 
 
1 = comparator mode.
[6:5]
00
R/
W
     Operation mode    These two bits set the operational mode for the ADT7310.
 
 
 
 
00 = continuous conversion (default). When one conversion is finished, the ADT7310
starts another.
 
 
 
 
01 = one shot. Conversion time is typically 240 ms.
 
 
 
 
10 = 1 SPS mode. Conversion time is typically 60 ms. This operational mode reduces the
average current consumption.
 
 
 
 
11 = shutdown. All circuitry except interface circuitry is powered down.
7
0
R/W
     Resolution
This bit sets up the resolution of the ADC when converting.
 
 
 
 
0 = 13-bit resolution. Sign bit + 12 bits gives a temperature resolution of 0.0625癈.
 
 
 
 
1 = 16-bit resolution. Sign bit + 15 bits gives a temperature resolution of 0.0078125癈.
