Hello,
is it legal to issue a NACK to the master in the middle of the incremental burst cycle?
In my case the SDRAM controller is setting ACK_O low when its internal buffer is full. I don't see a right way on how to recover from this situation.

Thanks,

I'm sorry, I forgot to mention that it an incremental burst on wishbone bus.

Yes, it's not mandatory to ACK on every cycle in the burst modes.
