Two PNP thermal transistors are integrated in Pineview-D processor. It is used as a diode and connects to an external digital thermal sensor EMC2103. CPU receives the data of junction temperature through SMBus. Note that, this is an inaccurate value and the temperature offset must be taken into account by reading MSR of CPU.

When the CPU junction temperature is more than 125C, CPU asserts the THERMTRIP# signal, and then stops all bus activities, and the core power must be shut down in the specified time.
