Datasheet
SLP#
Input
SLP# (Sleep), when asserted in Stop-Grant state, causes the 
processor to enter the Sleep state. During Sleep state, the 
processor stops providing internal clock signals to all units, leaving 
only the Phase-Locked Loop (PLL) still operating. Processors in this 
state will not recognize snoops or interrupts. The processor will 
recognize only assertion of the RESET# signal, deassertion of SLP#, 
and removal of the BCLK input while in Sleep state. If SLP# is 
deasserted, the processor exits Sleep state and returns to Stop-
Grant state, restarting its internal clock signals to the bus and 
processor core units. If DPSLP# is asserted while in the Sleep state, 
the processor will exit the Sleep state and transition to the Deep 
Sleep state.
SMI#
Input
SMI# (System Management Interrupt) is asserted asynchronously 
by system logic. On accepting a System Management Interrupt, the 
processor saves the current state and enters System Management 
Mode (SMM). An SMI Acknowledge transaction is issued and the 
processor begins program execution from the SMM handler.
If an SMI# is asserted during the deassertion of RESET#, then the 
processor will tristate its outputs.
STPCLK#
Input
STPCLK# (Stop Clock), when asserted, causes the processor to 
enter a low-power stop-grant state. The processor issues a Stop-
Grant Acknowledge transaction, and stops providing internal clock 
signals to all processor core units except the FSB and APIC units. 
The processor continues to snoop bus transactions and service 
interrupts while in Stop-Grant state. When STPCLK# is deasserted, 
the processor restarts its internal clock to all units and resumes 
execution. The assertion of STPCLK# has no effect on the bus 
clock; STPCLK# is an asynchronous input.
TCK
Input
TCK (Test Clock) provides the clock input for the processor Test Bus 
(also known as the Test Access Port). 
TDI
Input
TDI (Test Data In) transfers serial test data into the processor. TDI 
provides the serial input needed for JTAG specification support.
TDO
Output
TDO (Test Data Out) transfers serial test data out of the processor. 
TDO provides the serial output needed for JTAG specification 
support.

Input
TEST1, TEST2, TEST3, TEST4, TEST5, TEST6, and TEST7 have 
termination requirements.
THRMDA
Other
Thermal Diode Anode.
THRMDC
Other
Thermal Diode Cathode.
THERMTRIP#
Output
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 signalled to the 
system by the THERMTRIP# (Thermal Trip) pin.
