PROCHOT#
Processor Hot#: This will go active when the
processor temperature monitoring sensor(s) detects
that the processor has reached its maximum safe
operation temperature
Output: This indicates that the processor Thermal
Control Circuit (TCC) has been activated, if enabled.
Input: This signal can also be driven to the processor to
activate the TCC.

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 125°C.
This is signaled to the system by the THERMTRIP# pin.

VCC_SENSE
VCC_SENSE and VSS_SENSE provide an isolated, low
impedance connection to the processor core voltage
and ground. They can be used to sense or measure
voltage near the silicon.
