12description: |
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.
