4.4.1.1
For I²S, data is received most significant bit first, one DAI_SCLK delay after the transition of DAI_LRCK,
and is valid on the rising edge of DAI_SCLK. For the I²S format, the left channel data is presented when
DAI_LRCK is low; the right channel data is presented when DAI_LRCK is high.
4.4.1.2
For left-justified format, data is received most significant bit first on the first DAI_SCLK after a DAI_LRCK
transition and is valid on the rising edge of DAI_SCLK. For the left-justified format, the left channel data
is presented when DAI_LRCK is high and the right channel data is presented when DAI_LRCK is low.
