If the main oscillator is configured for HS mode with
PLL active, an oscillator start-up time (T
additional PLL time-out (T
out is typically 2 ms and allows the PLL to lock to the
main oscillator frequency. A timing diagram, indicating
the transition from the Timer1 oscillator to the main
oscillator for HS-PLL mode, is shown in Figure 2-10.
