CATERR#

Catastrophic Error: This signal indicates that the system has 

experienced a catastrophic error and cannot continue to operate. 

The processor will set this for non-recoverable machine check 

errors or other unrecoverable internal errors. 
On the processor, CATERR# is used for signaling the following 

types of errors:

• Legacy MCERRs – CATERR# is asserted for 16 BCLKs.
• Legacy IERRs – CATERR# remains asserted until warm or 

cold reset.

PECI

PECI (Platform Environment Control Interface): A serial 

sideband interface to the processor, it is used primarily for 

thermal, power, and error management.

PROCHOT#

Processor Hot: PROCHOT# goes active when the processor 

temperature monitoring sensor(s) detects that the processor has 

reached its maximum safe operating temperature. This indicates 

that the processor Thermal Control Circuit (TCC) has been 

activated, if enabled. This signal can also be driven to the 

processor to activate the TCC.

Toggling PROCHOT# more than once in 1.5

 ms 

period 

will result in constant Pn state of the processor.

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# signal.
