Digital interfaces
The registers embedded in the L3G4200DH may be accessed through both the I
serial interfaces. The latter may be software-configured to operate either in 3-wire or 4-wire
interface mode.
The serial interfaces are mapped onto the same pins. To select/exploit the I
CS line must be tied high (i.e., connected to Vdd_IO).
Table 11.

The L3G4200DH I
content can also be read back.
The relevant I
Table 12.
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 lines must be connected to Vdd_IO through an external pull-up
resistor. When the bus is free both the lines are high.
