How to connect a peripheral with "waitrequest" signal to the AVALON MM BUS?

[Altera_Forum]

I had a piggyback-board with 16K/16bits SRAM interface and a "waitrequest" signal, normal avalon mm-tri slave port can not support "waitrequest" signal, so how can i interface this board to the NIOS system?? 

Thanks!!:eek:

Is your peripheral shared with other peripherals on the tri-state bus? If not, you can create your own custom interface and create a regular Avalon MM slave rather than using the tri-state slave.

I perfer to share pins with a SRAM, of course, do not share also acceptable, but is there any detail document about how to creat a user avalon-mm slave interfacer to the off-chip peripheral?? Because the avalon-mm slave use separated readdata and writedata, how to connect them to a bi-direction data port in the peripheral? 

thank you!:)
