Digital interfaces
The registers embedded inside the LIS331DLF may be accessed through both the I
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 I
line must be tied high (i.e. connected to Vdd_IO).

I
The LIS331DLF I
content can also be read back.
The relevant I
Table 9.
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. 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.
