2.2 Controlpart
All functions are controlled via an I²C Bus interface. All data are stored into a latch circuit.
The telegram structure is built as follows:
Startcondition – chipaddress – any number of databytes – stopcondition.
For the databytes the following conditions must be fulfilled:
Before transmitting a databyte a subaddress byte must first be placed in the data
telegram.
