Power Management
Chapter
The Northbridge contains BIOS programmable registers to enable the system bus disconnect in response to Halt and Stop Grant special cycles. 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 point
