Preliminary Information AMD Athlon™ XP Processor Model 6 Data Sheet 24309E-March 2002 10.2 Pin List Table 20 cross-references Socket A pin location to signal name. The "L" (Level) column shows the electrical specification for this pin. "P" indicates a push-pull mode driven by a single source. "O" indicates open-drain mode that allows devices to share the pin. Note: The AMD Athlon processor supports push-pull drivers. For more information, see "Push-Pull (PP) Drivers" on page 6. The "P" (Port) column indicates if this signal is an input (I), output (O), or bidirectional (B) signal. The "R" (Reference) column indicates if this signal should be referenced to VSS (G) or VCC_CORE (P) planes for the purpose of signal routing with respect to the current return paths. Table 20.
