C BUS SPECIFICATION
6.1
The interface protocol comprises:
Interface Protocol
– 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
6.1.1 Receive Mode
S = Start
R/W = "0" -> Receive Mode (Chip can be programmed by
μ
P)
"1" -> Transmission Mode (Data could be received by
μ
P)
ACK = Acknowledge
P = Stop
TS = Testing mode
AZ = Auto zero remain
AI = Auto increment
6.1.2 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.
6.1.3 Reset Condition
A Power-On-Reset is invoked if the Supply-Voltage is below than 3.5V. After that the following data is writ-
ten automatically into the registers of all subaddresses:
