Figure 21.

I2C bus data

5.2.1

Receive mode

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

TS = Testing mode

AI = Auto increment

5.2.2

Transmission mode

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.
