Datasheet
All of the commands in Table 51 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.
Note:
Writing to a read-command register or reading from a write-command register will produce invalid
results.
The default command after reset is to a reserved value (00h). After reset, “Receive Byte” SMBus
packets will return invalid data until another command is sent to the thermal sensor.

SMBus Thermal Sensor Registers
7.4.6.1
Thermal Reference Registers
Once the SMBus thermal sensor reads the processor thermal diode, it performs an analog to digital
conversion and stores the result in the Thermal Reference Register (TRR). The supported range is
+127 to 0 decimal and is expressed as an eight-bit number representing temperature in degrees
Celsius. This eight-bit value consists of seven data bits and a sign bit (MSB) as shown in Table 52.
The values shown are also used to program the Thermal Limit Registers.
The values of these registers should be treated as saturating values. Values above 127 are
represented as 127 decimal, while values of zero and below may be represented as 0 to -127
decimal. If the thermal sensor returns a value with the sign bit set (1) and the data is 000_0000
through 111_1110, the temperature should be interpreted as 0 C.
7.4.6.2
Thermal Limit Registers
The SMBus thermal sensor has four Thermal Limit Registers: RRHL is used to read the high limit;
RRLL is read for the low limit; WRHL is used to write the high limit; and the WRLL to write the
low limit. These registers allow the user to define high and low limits for the processor core
thermal diode reading. The encoding for these registers is the same as for the Thermal Reference
Register shown in Table 52. If the processor thermal diode reading equals or exceeds one of these
limits, then the alarm bit (RHIGH or RLOW) in the Thermal Sensor Status Register is triggered.
