NOTES: 1. Left justified, stereo is the default input format.
2. IM[3:0] modes 0110 and 1101 are identical for the input SAP. OM[3:0] modes 0110 and 1101 do produce different results in the output SAP (see Figure 2−7).
3. If a 6 CH input format is selected, the output format must also be set to 6 CH. When in a 6 CH mode, data format selections—I

S and left justified—for the 6 Ch input
SAP can be made independent of the data format selections—I

S and left justified—made for the 6 CH output SAP.
4. IM[3:0] modes 1011 and 1111 are identical for the input SAP. OM[3:0] modes 1011 and 1111 do produce different results in the output SAP (see Figure 2−7).
