Also note, that registers a0, a1, d0, d1 always are scratch registers,
so you usually should only *pass* parameters there, but make a copy
directly after entering the function. To avoid problems of kind
"implementation defined behaviour", you should make a copy of A6 too,
when it is actually used.
In this example case, scratch register saving would not have been necessary
(since there are no other function calls inbetween), but we did it nevertheless.
