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.
