These registers can be accessed in the following way: * - PCI config registers are always accessible through PCI config space * - Full 512K space mapped into memory using PCI memory mapped access * - 256-byte I/O space mapped through PCI I/O access * - Full 512K space mapped through indirect I/O using PCI I/O access * It's possible to use either memory mapped mode or I/O mode to access * the registers, but memory mapped is usually the easiest.
