Figure 13. Signal Relationship Requirements During Power-Up Sequence
Notes: 1. Figure 13 represents several signals generically by using names not necessarily consistent
with any pin lists or schematics.
2. Requirements 1–8 in Figure 13 are described in "Power-Up Timing Requirements" on page 46.

Preliminary Information
The AMD Athlon™ XP processor model 8 is designed to provide
functional operation if the voltage and temperature parameters
are within the limits of normal operating ranges.
Figure 13 shows the relationship between key signals in the
system during a power-up sequence. This figure details the
requirements of the processor.
