I2C serial interface
The LSM9DS0 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 lines must be connected to Vdd_IO through external pull-up
resistors. When the bus is free, both lines are high.
The I2C interface is compliant with fast mode (400 kHz) I2C standards as well as with
normal mode.
