Hi. I'v read the data sheet for the 12F629/675. Is states a 1000 Tosc startup time after a=20 wakeup from sleep. But it also (in a note to fig 9-17) states a *1us* startup time *if* using RC-osc. Now, what is the startup time if using int osc mode ? Does that count as a special case of RC osc mode ?
