32.768KHz has a nice property that it oscillates 2^15 times per second

A little trickier dividing 32768 down to 60hz though.
Anybody got a simple way to do that in a micro?
Going to have short and long cycles, that's okay as long as they
eventually add up to 60hz.
Sure, you can do that. The 60 pulses won't all be the same length, but
they'll all be there. The counter in the target clock doesn't need a
pure 60 Hz tone, it just needs 60 rising edges per second.
