[sdiy] Tri-core oscillator sync

[Mattias Rickardsson]

I'd rather define it like:

"Hard sync" syncs the slave every time,

"soft sync" syncs the slave sometimes, i.e., when it has completed enough
of its cycle.

Then the actual sync type in both these above sync methods can be either
"reset sync" or "reversing sync".
