*: The oscillation time of the oscillator is the time it takes for the amplitude of the oscillations to reach 90%.

For crystal oscillators, this time is between several ms and several tens of ms, for ceramic oscillators the time is between several

hundred

μs and several ms, and for an external clock, the time is 0 ms.
