hi, i have a pci core up and running with my max-ii dev board. it has BAR0 - 1Mbyte and BAR1 256 bytes. IO read/write is fine but with offset 0h only, i'm wondering on how address (containing the offset) is coded in some ways, i know that selected DWORD is encoded in AD[7:0] i am able to read on offset:0h -- Sent from the OpenCores - PCI forum at Nabble.com: http://www.nabble.com/offset-t626438.html#a1669049 -------------- next part -------------- An HTML attachment was scrubbed...

The selected "DWORD" is encoded in AD[7:2]; the byte-enables select the bytes out of the word.
