30 Memory
Access
Control
(M)
This bit controls the PCI controller’s response to Memory Space accesses. A value of 0
disables the response. A value of 1 allows the controller to recognize a Memory access.
This bit is programmable (read/write from both the IP bus and PCI bus Configuration
cycles).
31 IO access
Control
(IO)
Fixed to 0. This bit is not implemented because there is no MPC5200B IO type space
accessible from the PCI bus. The PCI base address registers are Memory address ranges
only. Initialization software should write a 0 to this bit location.
