LSM6DSOTR Motion Sensor: Datasheet, Application Note, Pinout

The LSM6DSOST  is a system-in-package featuring a high-performance 3-axis digital accelerometer and 3-axis digital gyroscope.
The LSM6DSOST  delivers best-in-class motion sensing that can detect orientation and gestures in order to empower application developers and consumers with features and capabilities that are more sophisticated than orienting their devices to portrait and landscape mode. The event-detection interrupts enable efficient and reliable motion tracking and contextual awareness, implementing hardware recognition of free-fall events, 6  D orientation, click and double-click sensing, activity or inactivity, stationary/motion detection and wakeup events.
The LSM6DSOST  supports main OS requirements, offering real, virtual and batch mode sensors. In addition, the LSM6DSOST can efficiently run the sensor-related features specified in  Android, saving power and enabling faster reaction time. In particular, the LSM6DSOST  has been designed to implement hardware features such as significant motion detection, stationary/motion detection.  tilt, pedometer functions, timestamping and to support the data acquisition of an external magnetometer.
The LSM6DSOST  offers hardware flexibility to connect the pins with different mode connections to external sensors
to expand functionalities such as adding a sensor hub, auxiliary SPI, etc.

Pin connections
The LSM6DSO  offers flexibility to connect the pins  in order to have four different mode connections and
functionalities. In detail:
• Mode 1: I²C / MIPI I3CSM slave interface or SPI  (3- and 4-wire) serial interface is available;
• Mode 2: I²C / MIPI I3CSM slave interface or SPI  (3- and 4-wire) serial interface and I²C interface master for
external sensor connections are available;
• Mode 3: I²C / MIPI I3CSM slave interface or SPI  (3- and 4-wire) serial interface is available for the application
processor interface while an auxiliary SPI  (3- and 4-wire) serial interface for external sensor connections is
available for the gyroscope  ONLY;
• Mode 4: I²C / MIPI I3CSM slave interface or SPI  (3- and 4-wire) serial interface is available for the application
processor interface while an auxiliary SPI  (3- and 4-wire) serial interface for external sensor connections is
available for the accelerometer and gyroscope.

In the LSM6DSOTR, the accelerometer  and the gyroscope  can be turned on/off independently of each other and are
allowed to have different ODRs and power modes.
The LSM6DSOTR  has three  operating modes available:
• only accelerometer  active and gyroscope  in power-down
• only gyroscope  active and accelerometer  in power-down
• both accelerometer  and gyroscope  sensors active with independent ODR
The accelerometer is activated from power-down by writing ODR_XL  [3:0] in CTRL1_XL (10h) while the gyroscope 
is activated from power-down by writing ODR_G  [3:0] in CTRL2_G  (11h). For combo mode, the ODRs  are totally
independent
