2.3.2 Data synchronization
The sensor data from accelerometer and gyroscope are strictly synchronized on hardware level,
i.e. they run on exactly the same sampling rate.
BMI160 supports various level of data synchronization:
 Internal hardware synchronization of accelerometer, gyroscope and external sensor
data.
 High precision synchronization of external data with sensor data through hardware
timestamps. The hardware timestamp resolution is 39 µs.
 Hardware synchronization of the data of accelerometer, gyro and external sensor
through a unique DRDY interrupt signal.
 FIFO entries of the accelerometer, gyro and external sensor are already synchronized
by hardware. The according time stamp can be provided with each full FIFO read.
 Synchronization of external data (e.g. magnetometer data) with FIFO data at data
sampling granularity through hardware signaling
