Interrupts
  • Data-ready (e. g. for processor synchronization)
  • Any-motion (slope) detection (e. g. for wake-up)
  • Tap sensing (e. g. for tap-sensitive UI control)
  • Orientation change recognition (e. g. for portrait/landscape switching)
  • Flat detection (e. g. for position sensitive switching)
  • Low-g / high-g detection (e. g. for shock and free-fall detection)
  • No-motion (e.g. for power saving)
