Thermal Specifications and Design Considerations
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. Refer to Figure 5-3 for an illustration of this ordering.
The PROCHOT# signal is asserted when a high temperature situation is detected, regardless of
whether Thermal Monitor or Thermal Monitor 2 is enabled.
Note that the Thermal Monitor 2 TCC cannot be activated via the on demand mode. The Thermal
Monitor TCC, however, can be activated through the use of the on demand mode.
5.2.3
On-Demand Mode
The processor provides an auxiliary mechanism that allows system software to force the processor
to reduce its power consumption. This mechanism is referred to as “On-Demand” mode and is
distinct from the Thermal Monitor feature. On-Demand mode is intended as a means to reduce
system level power consumption. Systems using the Pentium 4 processor must not rely on software
usage of this mechanism to limit the processor temperature.
If bit 4 of the ACPI P_CNT Control Register (located in the processor IA32_THERM_CONTROL
MSR) is written to a '1', the processor will immediately reduce its power consumption via
modulation (starting and stopping) of the internal core clock, independent of the processor
temperature. When using On-Demand mode, the duty cycle of the clock modulation is
programmable via bits 3:1 of the same ACPI P_CNT Control Register. In On-Demand mode, the
duty cycle can be programmed from 12.5% on/87.5% off, to 87.5% on/12.5% off in 12.5%
increments. On-Demand mode may be used in conjunction with the Thermal Monitor. If the system
tries to enable On-Demand mode at the same time the TCC is engaged, the factory configured duty
cycle of the TCC will override the duty cycle selected by the On-Demand mode.
