Interface protocol
The interface protocol comprises:
●
●
●
●
●
●
●
Receive mode
S = Start
R/W =
ACK = Acknowledge
P = Stop
TS = Testing mode
AZ = AutoZero remain
AI = Auto increment
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.
Reset condition
A Power on reset is invoked if the supply voltage is below than 3.5 V. After that the following
data is written automatically into the registers of all subaddresses:
2
S 1 0 0 0 1 0
S
C bus specification
MSB
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 500 kbits/s
3.3 V logic compatible
