While you are at it you could also make a remark near
the explanation of the f000 motor control register,
and make it clear that this is a hardware function.
When I started to use this extra memory in leJOS I missed
the remark at the very end and assumed that it was some kind
of interrupt that copied this register to some hardware output port,
so I could use the rest of the memory freely. Not so ...
