Thermal Specifications and Design Considerations
The PROCHOT# signal is asserted when a high temperature situation is detected, regardless of
whether or not Thermal Monitor or Thermal Monitor 2 is enabled.
whether or not Thermal Monitor or Thermal Monitor 2 is enabled.
It should be noted that the Thermal Monitor 2 TCC can not be activated via the on demand mode.
The Thermal Monitor TCC, however, can be activated through the use of the on demand mode.
The Thermal Monitor TCC, however, can be activated through the use of the on demand mode.
If a processor has its Thermal Control Circuit activated via a Thermal Monitor 2 event, and an
Enhanced Intel SpeedStep technology transition to a higher target frequency (through the
applicable MSR write) is attempted, this frequency transition will be delayed until the TCC is
deactivated and the TM2 event is complete.
