    Another dumb question...does a cyclic DMA chain ever generate a flag at the DNR output?

      Hi again folks. In my novice naivete I've led myself to believe that a looping/cyclic chain DMA will issue a "done" flag once it hits the end of the last burst of the last TD. But, this doesn't ever seem to happen...it seems my DMA loops without ever issuing a "done" flag. Is this the correct behavior, or am I missing something? I'd really like to be able to keep tabs on the status of the DMA this way. Thanks all.
