6. Digital Interfaces
6.1. Interfaces
Beside the standard primary interface (I2C and SPI configurable), where sensor acts as a slave to the
application processor, BMA456 supports an auxiliary interface. See picture below.
If the auxiliary interface is enabled, the BMA456 can be connected to an external sensor (e.g. a
magnetometer) in order to build a 6-DoF solution. Then the BMA456 will act as a master to the external
sensor, reading the sensor data automatically and providing it to the application processor via the
primary interface.
