PCI Bus Interface
17.3.1.1
The PCI configuration header, shown in
utilizing a pair of 32-bit memory-mapped access registers. For PCI, CFG_ADDR is at offset 0x000 and
CFG_DATA is at offset 0x004.
17.3.1.1.1
The CFG_ADDR register is shown in
Table 17-4
Bus number 0xb00 and device number 0b0_0000 are used to configure the internal PCI configuration
header of the PCI controller itself.
