START
Start Address. This field determines the start address of
a particular memory area on the PPC bus which will be
used to access PCI bus resources. The value of this field
will be compared with the upper 16 bits of the incoming
PPC address.

END
End Address. This field determines the end address of a
particular memory area on the PPC bus which will be used
to access PCI bus resources. The value of this field will be
