Bug fix so that downward tone sweeps will work.
Fixed problem with tone_hi - tone_lo computation being done
with unsigned arithmetic, and thus always giving a positive result.

don't save r12
indeed..you're right, saving r12 seems to be not necessary.
i did some tests, even with gcc 5, all worked. but i'm still only 99.9% sure .-)
