13. PCI Controller (PCIC)
(13) PCI I/O Base Address Register (PCIIBAR)
This register is the I/O space base address register of the PCI configuration register space header
that is defined in PCI local bus specification. This register specifies the base address in the I/O
space of the PCIC.
See section 13.4.4 (2), Accessing PCIC I/O Space.

Description
I/O Space Base Address (upper 24 bits)
These bits specify the upper 24 bits of the base
address for the I/O space of the PCIC (PCIC control
register space).
I/O Space Base Address (lower 6 bits)
These bits are fixed to B'000000 by hardware.
Reserved
This bit is always read as 0. The write value should
always be 0.
Address Space Indicator
Indicates whether the base address indicated by this
register is in the I/O space or memory space.
0: Memory space
1: I/O space
