Preliminary Information
8 Electrical Data
This chapter describes the electrical characteristics that apply
to all desktop AMD Athlon™ XP processors model 10.
8.1 Conventions
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.
8.2 Interface Signal Groupings
The electrical data in this chapter is presented separately for
each signal group.
Table 9 defines each group and the signals contained in each
group.
