Abstract
A method of detecting a vibration comprises determining a vibration flag has been set during a running mode of the magnetic field sensor, remaining in the running mode until a predetermined number of vibration flags have been set, and entering a recalibration mode when the predetermined number of vibration flags have been set. A counter can be implemented for each of the plurality of vibration flags to determine if the predetermined number of vibration flags have been set.
