Features
6.4.6.5
Conversion Rate Registers
The contents of the Conversion Rate Registers determine the nominal rate at which analog to
digital conversions happen when the SMBus thermal sensor is in auto-convert mode. There are two
Conversion Rate Registers, RCR for reading the conversion rate value and WCR for writing the
value. Table 47 shows the mapping between Conversion Rate Register values and the conversion
rate. As indicated in Table 43, the Conversion Rate Register is set to its default state of 02h
(0.25 Hz nominally) when the thermal sensor is powered up. There is a ±30% error tolerance
between the conversion rate indicated in the conversion rate register and the actual conversion rate.
6.4.7
SMBus Thermal Sensor Alert Interrupt
The SMBus thermal sensor located on the processor includes the ability to interrupt the SMBus
when a fault condition exists. The fault conditions consist of: 1) a processor thermal diode value
measurement that exceeds a user-defined high or low threshold programmed into the Command
Register or 2) disconnection of the processor thermal diode from the thermal sensor. The interrupt
can be enabled and disabled via the thermal sensor Configuration Register and is delivered to the
baseboard via the SM_ALERT# open drain output. Once latched, the SM_ALERT# should only be
cleared by reading the Alert Response byte from the Alert Response Address of the thermal sensor.
The Alert Response Address is a special slave address shown in Table 42. The SM_ALERT# will
be cleared once the SMBus master device first reads the status register then reads the slave ARA
unless the fault condition persists. Reading the Status Register alone or setting the mask bit within
the Configuration Register does not clear the interrupt.
6.4.8
SMBus Device Addressing
Of the addresses broadcast across the SMBus, the memory component claims those of the form
“1010XXXZb”. The “XXX” bits are defined by pullups and pulldowns on the system baseboard.
These address pins are pulled down weakly (10 k
) on the processor substrate to ensure that the
memory components are in a known state in systems which do not support the SMBus, or only
support a partial implementation. The “Z” bit is the read/write bit for the serial bus transaction.
The thermal sensor internally decodes one of three upper address patterns from the bus of the form
“0011XXXZb”, “1001XXXZb”, or “0101XXXZb”. The device’s addressing, as implemented, uses
the SM_TS_A[1:0] pins in either the HI, LO, or Hi-Z state. Therefore, the thermal sensor supports
nine unique addresses. To set either pin for the Hi-Z state, the pin must be left floating. As before,
the “Z” bit is the read/write bit for the serial transaction.
