Figure 2–2. IIS-Compatible Serial Format (for 16-, 20-, and 24-bits)
Note the following characteristics of this protocol.
Left channel data is valid when LRCLK is low.
SDIN is sampled with the rising edge of SCLK.
SDOUT is transmitted on the falling edge of SCLK.
If LRCLK phase changes by more than 10 MCLKs, then the device is automatically reset.

Figure 2–3. MSB Left Justified Serial Interface Format (for 16-bits)
Note the following characteristics of this protocol.
Left channel data is valid when LRCLK is high.
The SDIN data is justified to the leading edge of LRCLK.
The MSBs are valid at the same time as the LRCLK edge for SDOUT, and captured at the very
next rising edge of SCLK for SDIN.
