Processor Power Signals
THERMTRIP#
Thermal Trip: The processor protects itself from catastrophic
overheating by use of an internal thermal sensor. This sensor is set
well above the normal operating temperature to ensure that there are
no false trips. The processor will stop all execution when the junction
temperature exceeds approximately 130 °C. This is signaled to the
system by the THERMTRIP# pin.

The processor requires this input signal to be a clean indication that
the V

, and V
DDQ
, power supplies are stable and
within specifications. This requirement applies, regardless of the S-
state of the processor. 'Clean' implies that the signal will remain low
(capable of sinking leakage current), without glitches, from the time
that the power supplies are turned on until they come within
specification. The signal must then transition monotonically to a high
state. This is connected to the PCH PROCPWRGD signal.

PROC_DETECT#
(BGA)
SKTOCC# (Socket Occupied)/PROC_DETECT (Processor
Detect): Pulled down directly (0 Ohms) on the processor package to
ground. There is no connection to the processor silicon for this signal.
System board designers may use this signal to determine if the
processor is present.
