Multichannel audio coder-decoder
8.11 Audio digital interface
The following audio formats can be selected via the microcontroller interface:
I
2
S-bus format with data word length of up to 24 bits
MSB-justified format with data word length of up to 24 bits
LSB-justified format with data word length of 16 bits, 20 bits or 24 bits
Multichannel formats with data word length of 20 bits or 24 bits. The used data lines
are DATAAD1 and DATADA1 and the sampling frequency must be below 50 kHz
The formats are illustrated in
