PCI Configuration Space 2
The following table is a summary of all the PCI configuration space registers. The registers that are block-mates with
the PCI interface (offset 00h - 3Ch) will be detailed following this table. The remainder of the registers will be detailed
with the blocks they control. This register space is for the 16650 UART.
