Table 7
ADAC audio feature registers
The sequence for controlling the ADAC audio feature registers via the L3-bus is given in the figure below.
Data transfer type ‘control registers’
When the data transfer type ‘control registers’ is selected 2 general control registers can be selected depending on bit 7
of the data byte (see Table 7).
The sequence for controlling the ADAC control registers via the L3-bus is given in the figure below.
