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)
