DESCRIPTION
Slot Length (number of bits per slot) in phase 1
0h = 8 bits
1h = 12 bits
2h = 16 bits
3h = 20 bits
4h = 24 bits
5h = 32 bits
6h = Reserved
7h = Reserved
Audio Sample Justification
0 = Left Justified
1 = Right Justified
Sample Length (sample length per slot) in phase 1
0h = 8 bits
1h = 12 bits
2h = 16 bits
3h = 20 bits
4h = 24 bits
5h = 32 bits
6h = Reserved
7h = Reserved
Note that, if the Slot Length > Sample Length, then each Slot will be
Left-Justified or Right-Justified depending on the AIF_FORMAT bit.
