I've been informed by Dave Seah that its more like 7 cycles/byte moved,
which in this case is 1792 cycles.  I'm sorry if I mislead anyone,
but as I don't have my chip yet, I can't test it out myself
yet.
 
Even so, use of this chip's new functions make the block move over twice
as fast:  3841/1792 = 2.14...
