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.
