Thermal Sensor Configuration Register
The configuration register of the thermal sensor controls the operating mode (Auto Convert vs.
Standby) of the device. Since the processor temperature varies dynamically during normal
operation, Auto Convert mode should be used exclusively to monitor processor temperature. Table
30 shows the format of the configuration register. If the RUN/STOP bit is low, then the thermal
sensor enters Auto Convert mode. If the RUN/STOP bit is set high, then the thermal sensor
immediately stops converting and enters the Standby mode. The thermal sensor will still perform
temperature conversions in Standby mode when it receives a one-shot command. However, the
result of a one-shot command during Auto Convert mode is not guaranteed. Intel does not
recommend using the one-shot command to monitor temperature when the processor is active, only
Auto Convert mode should be used. The thermal sensor can be configured in various interface
modes for temperature sampling. Intel recommends interfacing the thermal sensor using Interrupt
mode. For more detailed information regarding interface methods, please see the Intel
Mobile
Module Thermal Diode Temperature Sensor Application Note available through your Intel Field
Representative.
NOTE: All Reserved bits should be written as “0” and read as “don’t care” for programming purposes.

Standby mode control bit. If it is low, then the device enters Auto
Convert mode. If it is high, then the device immediately stops
converting and enters Standby mode where the one-shot command
can be performed.
