Table 29. Register 0×26 Remote 2 Temp TMIN/TRANGE Power-On Default = 61H
Bit
Name
R/W
Description
<7:3>
Remote 2
Temp TMIN
Read/Write
Contains the minimum temperature value for automatic fan speed control based on Remote 2
Temperature Readings. TMIN can be programmed to positive values only in 4°C increments.
Default is 32°C.
00000 = 0°C
00001 = 4°C
00010 = 8°C
00011 = 12°C
|
01100 = 48°C (Default)
|
11110 = 120°C
11111 = 124°C
<2:0>
Remote 2
Temp TRANGE
Read/Write
This nibble contains the temperature range value for automatic fan speed control based on the
Remote 2 Temp Readings.
000 = 5°C
001 = 10°C (Default)
010 = 20°C
011 = 40°C
100 = 80°C
Table 30. Register 0×3F Therm Behavior/Revision Power-On Default = 80H
Bit
Name
R/W
Description
<7>
Therm-to-
Fan En
Read/Write
Setting this bit to 1, enables the fan to run full-speed when THERM is asserted low. This allows the
system to be run in performance mode. Clearing this bit to 0 disables the fan from running full-speed
whenever THERM is asserted low. This allows the system to run in silent mode. (Power-On Default = 1).
<3:0>
Revision
Read Only
This nibble contains the revision number for the ADM1031.
Table 31. Register 0×0D Local Temperature Offset Power-On Default = 00H
Bit
Name
R/W
Description
<7>
Sign
Read/Write
When this bit is 0, the local offset is added to the Local Temperature Reading. When this bit is set to 1,
the local offset is subtracted from the Local Temperature Reading.
<3:0>
Local
Offset
Read Only
These four bits are used to add an offset to the Local Temperature Reading. These bits allow an offset
value of up to ±15°C to be added to or subtracted from the temperature reading.
Table 32. Register 0×0E Remote 1 Temperature Offset Power-On Default = 00H
Bit
Name
R/W
Description
<7>
Sign
Read/Write
When this bit is 0, the remote offset is added to the Remote 1 Temperature Reading. When this bit is
set to 1, the remote offset is subtracted from the Remote 1 Temperature Reading.
<6.4>
Unused
Read/Write
Unused. Read back 0.
<3:0>
Remote 1
Offset
Read/Write
These four bits are used to add an offset to the Remote 1 Temperature Reading. These bits allow an
offset value of up to ±15°C to be added to or subtracted from the temperature reading, depending on
the sign bit.
Table 33. Register 0×0F Remote 2 Temperature Offset Power-On Default = 00H
Bit
Name
R/W
Description
<7>
Sign
Read/Write
When this bit is 0, the remote offset is added to the Remote 2 Temperature Reading. When this bit is
set to 1, the remote offset is subtracted from the Remote 2 Temperature Reading.
<6.4>
Unused
Read/Write
Unused. Read back 0.
<3:0>
Remote 2
Offset
Read/Write
These four bits are used to add an offset to the Remote 2 Temperature Reading. These bits allow an
offset value of up to ±15°C to be added to or subtracted from the temperature reading, depending on
the sign bit.
