Significant power savings of the AMD Athlon processor
only occur if the processor is disconnected from the system
bus by the Northbridge while in the Halt or Stop Grant state.
The Northbridge can optionally initiate a bus disconnect
upon the receipt of a Halt or Stop Grant special cycle.
The option of disconnecting is controlled by an enable bits
in the Northbridge.
Program key features:
Enables bus disconnect bit in the Northbridge.
Full control under Clock Control (CLK_CTL) MSR
that determine the internal clock divisor when
Athlon system (S2k) bus is disconnected
