0012 description: |
0013 6-axis MotionTracking device that combines a 3-axis gyroscope and a 3-axis
0014 accelerometer.
0015
0016 It has a configurable host interface that supports I3C, I2C and SPI serial
0017 communication, features a 2kB FIFO and 2 programmable interrupts with
0018 ultra-low-power wake-on-motion support to minimize system power consumption.
0019
0020 Other industry-leading features include InvenSense on-chip APEX Motion
0021 Processing engine for gesture recognition, activity classification, and
0022 pedometer, along with programmable digital filters, and an embedded
0023 temperature sensor.
