I2C bus addresses and data
6.1
Chip address byte
The TDA7439 chip address is 0x88.
6.2
Sub-address byte
The function is selected by the 4-bit sub address as given in Table 7. The three MSBs are
not used and bit D4 selects address incrementing (B = 1) or single data byte (B = 0).
6.3
Data bytes
The function value is changed by the data byte as given in the following tables, Table 8 to
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.
