In my case, there is an I/O port (let's say for example address 0x200) and I must do: data_reg=0x200, addr_reg=data_reg + 2. Is there a way I can map them too to a memory region? There exist 2 memory i/o regions on the pci board, but I don't know their purpose. Propably one of them is to program an Altera FPGA that lies on the board...
