Just make your readdata and writedata signals 32 bits. It doesn&#39;t matter if you are only using bits 0-7. You can then ignore the byteenable and avoid the 3 "extra" non-functional read/writes.[/b]

That makes sense on the hardware side, but in the Nios IDE I don&#39;t see how it would work. When I call the IOWR macro for example, doesn&#39;t the input data need to match up to the bit width of the component data bus? How would I use the IOWR/IORD functions to use only the lowest byte of the 4 byte value?
