    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?
