All functions are controlled by an I
currently valid data are stored in a latch block. The telegram structure is as follows:
start condition - chip address - any number of bytes - stop condition
The following conditions apply to the data bytes:
Before the actual data byte (with setting information) a subaddress byte must always be
transmitted, which the I
Example: Headphones (HP) volume is to be increased in several steps.

Stop condition
Different subaddresses can be used within a telegram, ie without a new start condition. But the
change between listener and talker must always be made by stop condition - start condition - chip
address. A start condition and a chip address (talk) must always be transmitted before reading. This
loads the data that are to be read out on the I
