Hi If the device is attaching to a micro controller (as in the original request), feeding it a few bits to get it set up may not add any parts at all. No, that’s not a certainty, but it usually is a pretty good guess. Most micro’s these days will start up on an internal clock source so even the “what to use at time zero” issue is taken care of.
