6.3 Serial Interface
The device employs a standard I²C-serial bus.
6.3.1 Bus Description
A data transfer must be invoked by a master device (e.g. microcontroller) which defines the access to
the slave device. The master device defines and generates the serial clock (SCL) and the start/stop
conditions.
