13. PCI Controller (PCIC)
(2)
The PCI I/O address space should be allocated as 256 bytes.
The lower eight bits ([7:0]) are sent to the internal bus without translation.
When bits 31 to 8 of a PCI address match bits 31 to 8 of PCIIBAR, the upper 24 bits are replaced
with H'FE04 01 and a PCI local register is accessed.
