Description

PCI I/O Base Address

This is the base address value for I/O accesses cycles. It will be compared to

AD[31:7] in the address phase of bus command cycle for the I/O resource access

PCI I/O Range Indication

It indicates that the minimum I/O resource size is 80h

I/O Space Or Memory Space Base Indicator

Determines that the register maps into the I/O space ( = 1 Indicates I/O Base)
