- As far as I know (I've written an SLM804 driver lately) the CPU
- in an ST was free to do anything while dma transfer was taking place.
- The problem seems to be that drivers often use that freedom to make
- the processor poll the dma interrupt status all the time instead of
- just being interrupted when the dma transfer is complete.
