  Make this work a lot better:
          Remove a lot of older cruft not needed.
          Improve ISR support, but it is still unused since polling is faster
          Properly initalize the speed register to get 90kb/s, not 400b/s.
          Try to catch NACK
          Allow 0 length read transfers to generate start/top pairs.
