Thermal Zones
Offset Registers
There are three offset registers:
Offset Register 1 is used for Remote Diode 1 Temp Reading. Offset Register 2 is used for Remote
Diode 2 Temp Reading. Offset Register Ambient is used for internal Temp Reading.
The Offset Registers contain a 2's complement value which is added (or subtracted if the number is
negative) to the corresponding temperature reading. The default value in the offset register is zero, so
initially zero is always added to the temperature reading.
Each temperature measurement input is assigned to a Thermal Zone to control the PWM outputs in
Auto Fan Control mode. These zone assignments are as follows:
Offset Register Ambient (1Dh)
Offset Register 2 (1Eh)
Offset Register 1 (1Fh)
Zone 1 = Remote Diode 1 (Processor)
Zone 2 = Ambient (Internal) Temperature Sensor
Zone 3 = Remote Diode 2
