Does anybody know how to change address alignment in SOPC? I am trying to connect a non-memory chip to avalon bus. I need to change the address alighment to NATIVE. Otherwise, there is trouble when read the chip internal register.

thanks

    Without byte enable the slave port uses native address alignment and following formula is used to calculate the address:

    master address = slave base address + (slave word offset * master data width in bytes)
