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.

In order to address a specific device, the master device must generate a START condition by pulling

the data line (SDA) from a logic high level to a logic low lev-el while the serial clock signal (SCL) is

kept at high level.
