2I2C BUS INTERFACE
2.1 Interface Protocol
The interface protocol comprises:
-a start condition (S)
-a chip address byte (the LSB bit determines read / write transmission)
-a subaddress byte
-a sequence of data (N-bytes + acknowledge)
-a stop condition (P)
S = Start
R/W = “0” -> Receive-Mode (Chip could be programmed by P)
“1” -> Transmission-Mode (Data could be received by P)
ACK = Acknowledge
P = Stop
MAX CLOCK SPEED 500kbits/s
2.1.1 Auto increment
If bit I in the subaddress byte is set to “1”, the auto increment of the subaddress is enabled.
2.1.2 TRANSMITTED DATA (send mode)
SM = Soft mute activated
X = Not Used
The transmitted data is automatically updated after each ACK.
Transmission can be repeated without new chip address.
2.1.3 Reset Condition
A Power-On-Reset is invoked if the Supply-Voltage is below than 3.5V. After that, the following data is written
automatically into the registers of all subaddresses:
The programming after POR is marked bold-face / underlined in the programming tables.
With this programming all the outputs are muted to VREF (VOUT= VDD/2).
