Notes
1. PCI configuration accesses to CF8 (Configuration Address) and CFC
(Configuration Data) are supported by the MPC105 PCI
bridge/memory controller as specified in the PCI Specification
Revision 2.0.
2. Both Contiguous and Discontiguous mappings are supported by the
MVME1603/1604. Refer to the ISA/PCI I/O Space Mapping table for
more details.
3. This space is used for Direct Mapped PCI Configuration Space
accesses. Refer to the PCI Configuration Space Mapping section for
more details.
4. EPROM/FLASH decoding repeats every 1MB for this entire 16MB
range.
5. The usage of this 14MB address range for EPROM/FLASH is not
recommended, since future PowerPC products will redefine this area.
6. The M48T18 RTC and NVRAM device is mapped in this area. Refer
to the ISA/PCI I/O Space Mapping table for more details.
7. A read of any byte within this 16-byte range (BFFFFFF0 through
BFFFFFFF) causes a PCI IACK cycle. The data read is the IACK
vector.
