I have a general question about a PCI-to-PCI bridge. If the device has a positive decoder and receives an address in the range of the addresses it should respond. Then it claims the address and forwards it to the secondary interface. Now suppose no target on the secondary interface claims the transaction and master-abort happens for the second interface. What will happen to the primary interface then? Why PCI specifications do not explain the connection between the state machines of the primary and secondary interfaces?
