Description
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.
Unused. Read back zeros.
This nibble contains the revision number for the ADM1030.
Description
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.
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.
Description
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.
Unused. Normally read back zeros.
These four bits are used to add a two’s complement offset to the Remote
Temperature Reading, allowing 15 C to be added to or subtracted from the
temperature reading.
