NOTE: This is an 8-bit field. The device which sent the alert will respond to the ARA Packet with its address in
the seven most significant bits. The least significant bit is undefined and may return as a ‘1’ or ‘0’. See
Section 6.4.8 for details on the Thermal Sensor Device addressing.
All of the commands in Table 48 are for reading or writing registers in the SMBus thermal sensor,
except the one-shot command (OSHT) register. The one-shot command forces the immediate start
of a new conversion cycle. If a conversion is in progress when the one-shot command is received,
then the command is ignored. If the thermal sensor is in stand-by mode when the one-shot
command is received, a conversion is performed and the sensor returns to stand-by mode. The one-
shot command is not supported when the thermal sensor is in auto-convert mode.
