Shake detection debounce filtering requires n adjacent shake
detection events in order to trigger a shake event and set the
SHAKED bit in the TILT: Status Register. In addition, if the
SHINTX, SHINTY or SHINTZ bits are set in the INTEN: Interrupt
Enable Register and that event occurs, then an interrupt will be
generated by the device.
