D Left Justified Mode
In left-justified mode, the MSB of right channel is valid on the rising edge of BCLK, following the falling edge on
WCLK. Similarly the MSB of left channel is valid on the rising edge of BCLK following the rising edge of
WCLK.

D I2S Mode
In I2S mode, the MSB of left channel is valid on the second rising edge of BCLK, after the falling edge on
WCLK. Similarly the MSB of right channel is valid on the second rising edge of BCLK, after the rising edge of
WCLK.

D DSP Mode
In DSP mode, the falling edge of WCLK starts the data transfer with the left channel data first and immediately
followed by the right channel data. Each data bit is valid on the falling edge of BCLK.
