description: |

  6-axis MotionTracking device that combines a 3-axis gyroscope and a 3-axis

  accelerometer.



  It has a configurable host interface that supports I3C, I2C and SPI serial

  communication, features a 2kB FIFO and 2 programmable interrupts with

  ultra-low-power wake-on-motion support to minimize system power consumption.



  Other industry-leading features include InvenSense on-chip APEX Motion

  Processing engine for gesture recognition, activity classification, and

  pedometer, along with programmable digital filters, and an embedded

  temperature sensor.
