From UM10360 v3.1: "Once a clock is detected, the Wake-up Timer counts a fixed number of clocks (4,096), then sets the flag (OSCSTAT bit in the SCS register) that indicates that the main oscillator is ready for use." What clocks is that? The main oscillator clocks? Or internal RC clocks? I'm timing the wait-for-OSCSTAT loop. I takes ~570 IRC clocks for my 12MHz crystal.
