+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.
