AMD Athlon™ XP Processor Model 8 Data Sheet

11.2Pin List

Table 25 on page 66 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.

When the Northbridge receives the Halt or Stop Grant special cycle from the processor and, if there are no outstanding probes or data movements, the Northbridge deasserts CONNECT a minimum of eight SYSCLK periods after the last command sent to the processor. The processor detects the deassertion of CONNECT on a rising edge of SYSCLK and deasserts PROCRDY to the Northbridge. In return, the Northbridge asserts CLKFWDRST in anticipation of reestablishing a connection at some later pointPreliminary Information ChapterPower Management AMD Athlon XP Processor Model 8 Data SheetPreliminary Information 4.
