The interrupt is normally raised by the recieving device, rather than
the DMA controller itself, eg. when playing sounds on an SB, it is up
to the SB to tell you when the transfer is complete. Obviously methods
for doing this will depend on what device you are accessing.

I don't know if the DMA controller itself has any mechanism for doing
this, sorry. If it does, I've never come across that.
