requirements and implementation details.
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.

TMS
Input
TMS (Test Mode Select) is a JTAG specification support signal used
by debug tools.
by debug tools.
TRDY#
Input
TRDY# (Target Ready) is asserted by the target to indicate that it
is ready to receive a write or implicit writeback data transfer.
TRDY# must connect the appropriate pins of both FSB agents.

TRDY# must connect the appropriate pins of both FSB agents.
TRST#
Input
TRST# (Test Reset) resets the Test Access Port (TAP) logic. TRST#
must be driven low during power on Reset.
VCC
Input
Processor core power supply.
VCCA
Input
VCCA provides isolated power for the internal processor core PLLs
.
VCCP
Input
Processor I/O Power Supply.
VCCSENSE
Output
VCCSENSE together with VSSSENSE are voltage feedback signals
that control the 2.1 mΩ loadline at the processor die. It should be
used to sense voltage near the silicon with little noise.

used to sense voltage near the silicon with little noise.
VID[6:0]
Output
VID[6:0] (Voltage ID) pins are used to support automatic selection
of power supply voltages (V
of power supply voltages (V
CC
). Unlike some previous generations
of processors, these are CMOS signals that are driven by the
processor. The voltage supply for these pins must be valid before
the VR can supply V

must be disabled until the voltage supply for the VID pins becomes
valid. The VID pins are needed to support the processor voltage
specification variations. See

VSS
Input
