C bus addresses and data
I
Chip address byte
The TDA7439DS chip address is 0x88.
Sub-address byte
The function is selected by the 4-bit sub address as given in
not used and bit D4 selects address incrementing (B = 1) or single data byte (B = 0).
Table 7.
Data bytes
The function value is changed by the data byte as given in the following tables,
Table
In the tables of input gain, volume and attenuation, not all values are shown. A desired
intermediate value is obtained by setting the three LSBs to the appropriate value.
