[. . . ] A processor enabled for TM2 includes two operating points, each consisting of a specific operating frequency and voltage. The first operating point represents the normal operating condition for the processor. The second operating point consists of both a lower operating frequency and voltage. When the TCC is activated, the processor automatically transitions to the new frequency. During the frequency transition, the processor is unable to service any bus requests, all bus traffic is blocked. Edge-triggered interrupts will be latched and kept pending until the processor resumes operation at the new frequency. Once the new operating frequency is engaged, the processor will transition to the new core operating voltage by issuing a new VID code to the voltage regulator. The voltage regulator must support VID transitions in order to support TM2. During the voltage change, it will be necessary to transition through multiple VID codes to reach the target operating voltage. The processor continues to execute instructions during the voltage transition. Operation at the lower voltage reduces the power consumption of the processor, providing a temperature reduction. Thermal and Mechanical Design Guidelines 33 Thermal Management Logic and Thermal Monitor Feature Once the processor has sufficiently cooled, and a minimum activation time has expired, the operating frequency and voltage transition back to the normal system operating point. Transition of the VID code will occur first, in order to insure proper operation once the processor reaches its normal operating frequency. Thermal Monitor 2 Frequency and Voltage Ordering TTM2 Temperature PROCHOT# fMAX fTM2 VID VIDTM2 Time Refer to the datasheet for further information on TM2. Frequency VID 4. 2. 4 Operation and Configuration Thermal Monitor must be enabled to ensure proper processor operation. The Thermal Control Circuit feature can be configured and monitored in a number of ways. OEMs are required to enable the Thermal Control Circuit while using various registers and outputs to monitor the processor thermal status. The Thermal Control Circuit is enabled by the BIOS setting a bit in an MSR (model specific register). Enabling the Thermal Control Circuit allows the processor to attempt to maintain a safe operating temperature without the need for special software drivers or interrupt handling routines. When the Thermal Control Circuit has been enabled, processor power consumption will be reduced after the thermal sensor detects a high temperature (that is, PROCHOT# assertion). The Thermal Control Circuit and PROCHOT# transitions to inactive once the temperature has been reduced below the thermal trip point, although a small time-based hysteresis has been included to prevent multiple PROCHOT# transitions around the trip point. External hardware can monitor PROCHOT# and generate an interrupt whenever there is a transition from active-to-inactive or inactive-to-active. PROCHOT# can also be configured to generate an internal interrupt which would initiate an OEM supplied interrupt service routine. 34 Thermal and Mechanical Design Guidelines Thermal Management Logic and Thermal Monitor Feature Regardless of the configuration selected, PROCHOT# will always indicate the thermal status of the processor. The power reduction mechanism of thermal monitor can also be activated manually using an "on-demand" mode.
