Register Descriptions

Table 13.2 shows a list of PCIC registers. The addresses and offsets of PCI configuration registers
are the values used when the PCIC is in little endian mode. The access size is the maximum access
size in each register. The registers in the PCI configuration register space can be accessed with
32-, 16-, or 8-bit access sizes.
