Thermal Specifications and Design Considerations

Datasheet

The PROCHOT# signal is asserted when a high temperature situation is detected,

regardless of whether Thermal Monitor or Thermal Monitor 2 is enabled.

It should be noted 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

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.

5.2.4

PROCHOT# Signal

An external signal, PROCHOT# (processor hot), is asserted when the processor core

temperature has reached its maximum operating temperature. If the Thermal Monitor

is enabled (note that the Thermal Monitor must be enabled for the processor to be
