ACK = Acknowledge
P = Stop
TS = Testing mode
AI = Auto increment
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.
Reset condition
A Power-On-Reset is invoked if the supply voltage is below than 3.5V. After that the registers
are initialized to the default data written in following tables.
