Note 1. When setting up the sub-clock oscillator, ask the oscillator manufacturer for an oscillation evaluation and use the results as the

recommended oscillation stabilization time.

After changing the setting in the SOSCCR.SOSTP bit to start sub-clock operation, only start using the sub-clock oscillator after the

sub-clock oscillation stabilization time elapses with an adequate margin. A value that is two times the value shown is recommended.
