Pin connections

The ISM330DLC offers flexibility to connect the pins in order to have four different mode

connections and functionalities. In detail:



Mode 1: I2C slave interface or SPI (3- and 4-wire) serial interface is available;



Mode 2: I2C slave interface or SPI (3- and 4-wire) serial interface and I2C interface

master for external sensor connections are available;



Mode 3: I2C 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 is

available for an auxiliary host to access the gyroscope ONLY;



Mode 4: I2C 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 is

available for an auxiliary host to access the accelerometer and gyroscope.
