1. A method for tuning an oscillator of an event-sensitive device, comprising:

  • setting a threshold value corresponding to an acceptable frequency variation range;

    determining an error count corresponding to a difference between a measured frequency value and a desired frequency value;

    determining if the error count exceeds the threshold value; and

    tuning the oscillator to a frequency that is closer to the desired frequency value if the error count exceeds the threshold value.
