Config_Data Register - Motorola MVME5100 Programmer's Reference Manual

CONFIG_DATA Register

The description of the CONFIG_DATA register is also presented in three
perspectives; from the PCI bus, from the PPC Bus in Big Endian mode,
and from the PPC bus in Little Endian mode. Note that the view from the
PCI bus is purely conceptual, since there is no way to access the
CONFIG_DATA register from the PCI bus.Conceptual perspective from
the PCI bus:
