86 / 204 page  4−10 4.15 PCI Bus Number Register The PCI bus number register is programmed by the host system to indicate the bus number of the PCI bus to which the PCI6x21/PCI6x11 controller is connected. The PCI6x21/PCI6x11 controller uses this register in conjunction with the CardBus bus number and subordinate bus number registers to determine when to forward PCI configuration cycles to its secondary buses. Bit 7 6 5 4 3 2 1 0 Name PCI bus number Type RW RW RW RW RW RW RW RW Default 0 0 0 0 0 0 0 0 Register: PCI bus number Offset: 18h (Functions 0, 1) Type: Read/Write Default: 00h 4.16 CardBus Bus Number Register The CardBus bus number register is programmed by the host system to indicate the bus number of the CardBus bus to which the PCI6x21/PCI6x11 controller is connected. The PCI6x21/PCI6x11 controller uses this register in conjunction with the PCI bus number and subordinate bus number registers to determine when to forward PCI configuration cycles to its secondary buses. This register is separate for each PCI6x21/PCI6x11 controller function. Bit 7 6 5 4 3 2 1 0 Name CardBus bus number Type RW RW RW RW RW RW RW RW Default 0 0 0 0 0 0 0 0 Register: CardBus bus number Offset: 19h Type: Read/Write Default: 00h 4.17 Subordinate Bus Number Register The subordinate bus number register is programmed by the host system to indicate the highest numbered bus below the CardBus bus. The PCI6x21/PCI6x11 controller uses this register in conjunction with the PCI bus number and CardBus bus number registers to determine when to forward PCI configuration cycles to its secondary buses. This register is separate for each CardBus controller function. Bit 7 6 5 4 3 2 1 0 Name Subordinate bus number Type RW RW RW RW RW RW RW RW Default 0 0 0 0 0 0 0 0 Register: Subordinate bus number Offset: 1Ah Type: Read/Write Default: 00h |
