2.2.3 MSB-Left-Justified, Serial-Interface Format
The normal output mode for the MSB-left-justified, serial-interface format is for 16, 18, 20, or 24 bits.
Figure 2−3 shows the following characteristics of this protocol:
• Left channel is transmitted when LRCLK is high.
• The SDIN data is justified to the leading edge of the LRCLK.
• The MSBs are transmitted at the same time as LRCLK edge and captured at the next rising edge of SCLK.
