5.11.2 I²C Function
The I²C slave interface operates in 7 bit addressing mode with a maximum frequency of 400 kHz (fast mode). To
synchronize the IC to different operation voltages of the I²C bus the interface has a separate supply voltage input
at pin VDDIO which is responsible for all interface pins. For more details of the addressing modes please refer to
the "I²C - BUS SPECIFICATION VERSION 2.1" from Philips.
