AMD Athlon™ XP Processor Model 6 Data Sheet
24309E—March 2002
Preliminary Information
Note:
In response to Halt special cycles, the Northbridge passes the
Halt special cycle to the PCI bus or Southbridge
immediately.
The processor can receive an interrupt after it sends a Halt
special cycle, or STPCLK# deassertion after it sends a Stop
Grant s pecial cy cle to the Nor thbridge but befo re the
disconnect actually occurs. In this case, the processor sends the
Connect spe cia l cycle to the Nor thbridge , rather than
continuing with the disconnect sequence. In response to the
Connect special cycle, the Northbridge cancels the disconnect
request.
The system is required to assert the CONNECT signal before
returning the C-bit for the connect special cycle (assuming
CONNECT has been deasserted).
For more information, see the
AMD Athlon™ and AMD Duron™
System Bus Specification
, order# 21902 for the definition of the
C-bit and the Connect special cycle.
