- 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?
