Is it possible to have both complex DMA and DSPMSG protocol operating at
the smae time? This is probably not possible, because you request a DMA
transfer by sending a certain word to the host. Therefore, in DMA mode, the
host would be looking for such a command, and would not know what to do with
it.
However, if this is the case, is there documentation on all of the messages
used in Complex DMA mode? Perhaps you can prefix a standard DSP reply with a
certain header?
