You use different address values to access your module. For example: address 0 => input 0, address 1 => input 1, address 2 => output. Your code needs to look at the address lines to decide what is being accessed. Read the material I mentioned on Qsys. It's explained there.

For PIO connected to Lightweight AXI, for example, if you want to read or write an address with the same offset ,the adress you need to pass to the function is the same, the only change is the function (read or write)
