FAN_FAULT
/REF
R/W
This bit sets the function for Pin 8. 0 = Default = FAN_FAULT
output (THERM
input
is CMOS). 1 = Reference input for THERM
.

THERM
% Time Window
R/W
These bits set the time window over which THERM
% is calculated.
000 = 0.25 second
001 = 0.5 second
010 = 1 second
011 = 2 seconds
100 = 4 seconds
101 = 8 seconds
110 = 8 seconds
111 = 8 seconds
3
XOR Test
R/W
Set this bit to 1 to enable the XOR connectivity test.
2
Enable Remote 2 THERM
Events
R/W
This bit enables THERM
assertions as an output. Functions when the THERM
timer
is enabled and the Remote 2 temperature exceeeds its THERM
limit.
1
Enable Remote 1 THERM
Events
R/W
This bit enables THERM
assertions as an output. Functions when the THERM
timer
is enabled and the Remote 1 temperature exceeeds its THERM
limit.
0
Enable Local THERM
Events
R/W
This bit enables THERM
assertions as an output. Functions when the THERM
timer
is enabled and the local temperature exceeeds its THERM
limit.

Conversion Rate
R/W
These four bits set the conversion rate of the ADM1034. Changing these bits does
not update the conversion rate until the start of the next round robin.
0000 = 0.0625 conversions/second
0001 = 0.125 conversions/second
0010 = 0.25 conversions/second
0011 = 0.5 conversions/second
0100 = 1 conversion/second
0101 = 2 conversions/second
0110 = 4 conversions/second
0111 = 8 conversions/second = Default
1000 = 16 conversions/second
1001 = 32 conversions/second
1010 = 64 conversions/second

Fault Queue Length
R/W
These four bits set the fault queue (the number of out-of-limit measurements made
before an ALERT
is generated).
000x = 1
001x = 2
01xx = 3
