Digital interfaces
The registers embedded inside the LSM303DLH are accessible through two separate I
serial interfaces: one for the accelerometer core and the other for the magnetometer core.
The two interfaces can be connected together on the PCB.

There are two signals associated with the I
data line (SDA). The latter is a bidirectional line used for sending and receiving the data
to/from the interface.
