  12 description: |
  13   6-axis MotionTracking device that combines a 3-axis gyroscope and a 3-axis
  14   accelerometer.
  15
  16   It has a configurable host interface that supports I3C, I2C and SPI serial
  17   communication, features a 2kB FIFO and 2 programmable interrupts with
  18   ultra-low-power wake-on-motion support to minimize system power consumption.
  19
  20   Other industry-leading features include InvenSense on-chip APEX Motion
  21   Processing engine for gesture recognition, activity classification, and
  22   pedometer, along with programmable digital filters, and an embedded
  23   temperature sensor.
