Abstract
Techniques are disclosed relating to oscillator settling time allowance. In one embodiment, an apparatus may include an oscillator and oscillation detection and control circuitry. The oscillation detection and control circuitry may be configured to awaken an oscillator at a predetermined time and detect an edge transition of oscillations. The oscillation detection and control circuitry may further be configured to measure the time from the power-on indication to edge transition detection. In one embodiment, the oscillation detection and control circuitry may be configured to store the measured time and use the measured time instead of the predetermined time for subsequent oscillator awakenings. In some embodiments, the apparatus may further include circuitry configured to compensate for an expected oscillator settling behavior.
