Digital interfaces
The registers embedded inside the LIS331DLF 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.
The serial interfaces are mapped onto the same pads. To select/exploit the I2C interface, CS
line must be tied high (i.e. connected to Vdd_IO).
5.1
I2C serial interface
The LIS331DLF I2C is a bus slave. The I2C is employed to write data into 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. Both the lines are connected to Vdd_IO through a pull-up resistor
embedded inside the LIS331DLF. When the bus is free both the lines are high.
The I2C interface is compliant with fast mode (400 kHz) I2C standards as well as with the
normal mode.
