Preliminary Information
This chapter describes the electrical characteristics that apply
to all desktop AMD Athlon™ XP processors model 8.
The conventions used in this chapter are as follows:
Current specified as being sourced by the processor is
negative.
Current specified as being sunk by the processor is positive.
The electrical data in this chapter is presented separately for
each signal group.
Table 8 defines each group and the signals contained in each
group.
