Valid in 16-bit left justified mode only.
NOTES:
3. Timing relative to 256 fs MCLK.
4. SCLK rising and falling are measured from 20% to 80%.
5. The rising edge of SCLK must not occur at the same time as either edge of LRCLK.

A device must internally provide a hold time of at least 300 ns for the SDA signal to bridge the undefined region of the
falling edge of SCL.
NOTES:
6. tw(low) is measured from the end of tf to the beginning of tr.
7. tw(high) is measured from the end of tr to the beginning of tf.
