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.

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.

O

GTL

PECI

Platform Environment Control Interface: A serial

sideband interface to the processor, it is used primarily for

thermal, power, and error management.

I/O

Asynchronous

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.

GTL Input

Open-Drain Output

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.

O

Asynchronous OD

Asynchronous CMOS

SM_DRAMPWROK

SM_DRAMPWROK Processor Input: This signal

connects to the PCH DRAMPWROK.

I

Asynchronous CMOS

PWRGOOD

The processor requires this input signal to be a clean

indication that the V

CC

 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 the

supplies come within specification. The signal must

then transition monotonically to a high state.

I

Asynchronous CMOS

SKTOCC#

(Processor Detect): This signal is 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.
