PCI Bus Interface
16.3.1.1
The PCI configuration header, shown in
method 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.
16.3.1.1.1
The CFG_ADDR register is shown in
Table 16-4
Bus number 0xb00 and device number 0b0_0000 are used to configure the internal PCI configuration
header of the PCI controller itself.
