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.

Configuration Register
The Configuration Register controls the operating mode (stand-by vs. auto-convert) of the SMBus
thermal sensor. Table 47 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
Table 47. SMBus Thermal Sensor Configuration Register

MASK
0
Mask SM_ALERT# bit. Clear the bit to allow interrupts via
SM_ALERT# and allow the thermal sensor to respond to the ARA
commandwhenanalarm is active. Set the bittodisable interrupt
mode. The bit is not used to clear the state of the SM_ALERT# output.
An ARA command may not be recognized if the mask is enabled.
6
RUN/STOP
0
Stand-by mode control bit. If set, the device immediately stops
converting, and enters stand-by mode. If cleared, the device converts
in either one-shot mode or automatically updates on a timed basis.
