The PCI Slave Address Registers (PSADDx) contain address information
associated with the mapping of PCI memory space to PPC memory space.
The fields within the PSADDx registers are defined as follows:
START Start Address. This field determines the start address of
a particular memory area on the PCI bus which will be
used to access PPC bus resources. The value of this field
will be compared with the upper 16 bits of the incoming
PCI address.
END End Address. This field determines the end address of a
particular memory area on the PCI bus which will be used
to access PPC bus resources. The value of this field will
be compared with the upper 16 bits of the incoming PCI
address.
