Base Address 0
This is the PCI I/O address space base address for the Operation registers.
Bit 0: I/O Space Indicator
This bit always reads back a ‘1’, indicating that this base address register defines a PCI I/O space.
Bit 1: Reserved
This bit always reads back a ‘1’, indicating that this base address register defines a PCI I/O space.
Bits 31-2: I/O Base Address
This bit is a read-only ‘0’ in accordance with the PCI specification for I/O base address
configuration registers.
