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.
