Reserved, Unused Pins, and TESTHI[10:0]
All RESERVED pins must remain unconnected. Connection of these pins to V

, V
SS
, or to any
other signal (including each other) can result in component malfunction or incompatibility with
future Pentium 4 processors. See Chapter 5.0 for a pin listing of the processor and the location of
all RESERVED pins.
future Pentium 4 processors. See Chapter 5.0 for a pin listing of the processor and the location of
all RESERVED pins.
For reliable operation, always connect unused inputs or bidirectional signals to an appropriate
signal level. In a system level design, on-die termination has been included on the Pentium 4
processor to allow signals to be terminated within the processor silicon. Most unused AGTL+
inputs should be left as no connects, as AGTL+ termination is provided on the processor silicon.
However, see Table 3 for details on AGTL+ signals that do not include on-die termination. Unused
active high inputs should be connected through a resistor to ground (V

left unconnected, however this may interfere with some TAP functions, complicate debug probing,
and prevent boudary scan testing. A resistor must be used when tying bidirectional signals to power
or ground. When tying any signal to power or ground, a resistor will also allow for system
testability. For unused AGTL+ input or I/O signals, use pull-up resistors of the same value for the
on-die termination resistors (R
