11.2 Pin List
Table 24 on page 64 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.
