7.1 PCI Bus 0, Device 0, Function 0 Registers
PCI Bus 0, Device 0, contains configuration registers that are
mostly specific to the AMD-761 system controller and its
processor, DDR SDRAM, AGP, and PCI bus interfaces. The Bus
0, Device 0 space contains two separate functions as follows:
„ Function 0 contains standard PCI configuration space,
timing and arbitration control for each interface, and
memory decode registers.
„ Function 1 contains DDR drive strength control and
calibration control for the programmable delay lines (PDLs)
of the DRAM interface.
