Digital interfaces
The registers embedded inside the LSM330DL may be accessed through both the I2C and
SPI serial interfaces. The latter may be SW configured to operate either in 3-wire or 4-wire
interface mode.
To select/exploit the I2C interface, the CS line must be tied high (i.e. connected to Vdd_IO).
5.1
I2C serial interface
The LSM330DL I2C is a bus slave. The I2C is employed to write data into the registers
whose content can also be read back.
The relevant I2C terminology is given in the table below.
There are two signals associated with the I2C bus: the serial clock line (SCL) and the serial
data line (SDA). The latter is a bidirectional line used for sending and receiving the data
to/from the interface.
