Figure 21. I²C bus data
I²C bus specification
5.2.1 Receive mode
S 1 0 0 0 1 0 0 R/W ACK TS X AI A4 A3 A2 A1 A0 ACK DATA ACK P
S = Start
R/W = "0" -> Receive Mode (Chip can be programmed by µP)
"1" -> Transmission Mode (Data could be received by µP)
ACK = Acknowledge
P = Stop
5.2.2
TS = Testing mode
AI = Auto increment
Transmission mode
S 1 0 0 0 1 0 0 R/W ACK X X X X X X BZ SM ACK P
SM = Soft mute activated for main channel
BZ = Softstep Busy (‘0’ = Busy)
X = Not used
The transmitted data is automatic updated after each ACK. Transmission can be repeated
without new chip address.
5.2.3
Reset condition
A Power-On-Reset is invoked if the supply voltage is below than 3.5 V. After that the
registers are initialized to the default data written in following tables.
