Preliminary Information
The AMD Athlon™ XP processor model 6 is designed to provide
functional operation if the voltage and temperature parameters
are within the limits of normal operating ranges.
Figure 12 shows the relationship between key signals in the
system during a power-up sequence. This figure details the
requirements of the processor.
