Digital interfaces
The registers embedded inside the LIS3LV02DL 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).

Table 10.
There are two signals associated with the I
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 LIS3LV02DL. When the bus is free both the lines are high.
