Note:
For ceramic or quartz oscillators, typically the oscillation stabilization wait time of several to some
tens of milliseconds is required until the oscillation is stabilized at the natural oscillation. after it
begins. For this reason, set the wait time value meeting the oscillator used.
For details, see "5.5 Oscillation Stabilization Wait Time".
Oscillation Stabilization Waiting Reset State
The reset operation in response to a reset which occurs during power on reset or in stop or sub clock mode
begins after passing the oscillation stabilization wait time produced by the timebase timer expires. The reset
operation is performed after the external reset is released.
