Abstract
A method of detecting a vibration comprises determining a vibration flag has been set during a running mode, entering a vibration mode, providing direction information for a target object during the vibration mode of the magnetic field sensor, holding onto positive peak values and negative peak values of the magnetic field signal during the vibration mode of the magnetic field sensor, and returning to the running mode after receiving at least two clock cycles of the magnetic field signal with no further vibration flags set.
