be used when tying bi-directional signals to power or
ground. When tying any signal to power or ground, a
resistor will also allow for fully testing the processor
after board assembly.
For unused pins, it is suggested that ~10KΩ resistors
be used for pull-ups (except for PICD[1:0] discussed
above), and ~1KΩ resistors be used as pull-downs.
Never tie a pin directly to a supply other than the

Current may flow through the buffer ESD diodes when VIH > VCCP+1.1V, as in a power supply fault condition or while
power supplies are sequencing. Thermal stress should be minimized by cycling power off if the V

Maximum Ratings
Table 3 contains Pentium Pro processor stress
ratings only. Functional operation at the absolute
maximum
and
minimum
guaranteed. The Pentium Pro processor should not
receive a clock while subjected to these conditions.
Functional operating conditions are given in the AC
and DC tables. Extended exposure to the maximum
ratings may affect device reliability. Furthermore,
although the Pentium Pro processor contains
protective circuitry to resist damage from static
electric
discharge,
precautions to avoid high static voltages or electric
fields.
