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)
