Table XXIV. Register 0x3F Therm Behavior/Revision Power-On Default = 80H
Bit
Name
R/W
Description
<7>
Therm-to-Fan Enable 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.) Note that this bit has
no effect whenever THERM is pulled low as an input.

Table XXV. Register 0x0D Local Temp Offset Power-On Default = 00H
Bit
Name
R/W
Description
<7>
Sign
Read/Write
When this bit is 0, the local offset will be added to the Local Temperature Reading.
When this bit is set to 1, the local temperature offset will be subtracted from the
Local Temperature Reading.

Local Offset
Read/Write
Read/Write
Unused. Normally read back zeros.
These four bits are used to add a two’s complement offset to the Local Temperature
Reading, allowing 15∞C to be added to or subtracted from the temperature reading.
Table XXVI. Register 0x0E Remote Temp Offset Power-On Default = 00H
Bit
Name
R/W
Description
<7>
Sign
Read/Write
When this bit is 0, the remote offset will be added to the Remote Temperature
Reading. When this bit is set to 1, the remote temperature offset will be subtracted
from the Remote Temperature Reading.
