Interface Protocol
The interface protocol comprises:
a start condition (S)
a chip address byte (the LSB determines read/write transmission)
a subaddress byte
a sequence of data (N-bytes + acknowledge)
a stop condition (P)
the max. clock speed is 500kbits/s
3.3V logic compatible

5.1.1
Receive Mode
S = Start
R/W = "0" -> Receive Mode (Chip can be programmed by P)
"1" -> Transmission Mode (Data could be received by P)
ACK = Acknowledge
P = Stop
TS = Testing mode
AZ = Auto zero remain
AI = Auto increment
5.1.2
Transmission Mode
SM = Soft mute activated for main channel
X = Not Used
The transmitted data is automatic updated after each ACK. Transmission can be repeated
without new chip address.
5.1.3
Reset Condition
A Power-On-Reset is invoked if the Supply-Voltage is below than 3.5V. After that the
following data is written automatically into the registers of all subaddresses:
