Status Register
The Status Register shown in Table 53 indicates which (if any) thermal value thresholds for the
processor core thermal diode have been exceeded. It also indicates if a conversion is in progress or
if an open circuit has been detected in the processor core thermal diode connection. Once set, alarm
bits stay set until they are cleared by a Status Register read. A successful read to the Status Register
will clear any alarm bits that may have been set, unless the alarm condition persists. If the
SM_ALERT# signal is enabled via the Thermal Sensor Configuration Register and a thermal diode
threshold is exceeded, an alert will be sent to the platform via the SM_ALERT# signal.
This register is read by accessing the RS Command Register.

7.4.6.4
Configuration Register
The Configuration Register controls the operating mode (stand-by vs. auto-convert) of the SMBus
thermal sensor. Table 54 shows the format of the Configuration Register. If the RUN/STOP bit is
set (high) then the thermal sensor immediately stops converting and enters stand-by mode. The
thermal sensor will still perform analog to digital conversions in stand-by mode when it receives a
one-shot command. If the RUN/STOP bit is clear (low) then the thermal sensor enters auto-
conversion mode.
This register is accessed by using the thermal sensor Command Register: The RC command
register is used for read commands and the WC command register is used for write commands. See
