To initiate a PCI cycle from the PPC bus, the PPC address must be greater
than or equal to the START field and less than or equal to the END field.
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 compared with the upper 16 bits
of the incoming PPC address.
