Hello All, I would like to know how to generate PCIe INTx interrupt from Legacy PCIe EP in PPC440SPe. Also, please clarify, Page 741 of the user manual (PPC440SPe_UM2014_V1_26.pdf) write Assert_INTx message to INT_ADDR[61:63]. Page 739, table 27-9, mentions, Assert_INTA by writing to Outbound GBIF write channel 9, A[52:59]=0x20. Whether the INT_ADDR is any addresses BAR3 / POM3 address? What is the Assert_INTx value to be written to INT_ADDR[61:63]? How do I correlate with the message code values given in PCI express system architecture? The message codes given in PCI express system architecture is as follows
INTx Messages Message Code Assert_INTA 0010 0000 Assert_INTB 0010 0001 Assert_INTC 0010 0010 Assert_INTD 0010 0011 Deassert_INTA 0010 0100 Deassert_INTB 0010 0101 Deassert_INTC 0010 0110 Deassert_INTD 0010 0111 Regards, Kans.
