Currently redesign a rather old MPC8240 design to convert that processor from the agent mode to host mode. How does this host recognize PCI addresses on the bus, since the datasheet claims the LMBAR is not functional for the host mode. Thanks

As a target, but performing as a host, how does the MPC8240 recognize a PCI data packet from another PCI master is destined for that host ?  Just the range of the SDRAM set in the SDRAM configuration registers ?   Thanks

Thanks very much for the clarification

There is no address translation when the MPC8240 is configured as PCI Host and is accessed by a PCI agent.

This means that the processor's memory map shown in the MPC8240 Integrated Processor User’s Manual, Table 3-2. Address Map B—PCI Memory Master View in Host Mode is directly accessible from PCI.
