Avalon Bus Address alignment

Hi, I want to know how to use the Avalon Bus Address alignment feature. Is it automated by the Nios to choose the address alignment or do we have to manually do it ?

Hi,

I tried the above method but when master sends the address as BASE + 00 it corresponds to address "0" of the control register..

and when the master sends the address as BASE + 04 instead of corresponding to the address "1" I'm getting "4". What could be the reason for this.

From what I understand the addresses sent by master are not under my control. It is supposed to understand the address alignment and send the address, but it is not happening. Help needed.
