I2S Mode
Right-Justified (RJ) Mode
In I2S mode, the data is left-justified, MSB first, with the MSB
placed in the second BCLK period following the transition of
the LRCLK. A high-to-low transition of the LRCLK signifies the
beginning of the left channel data transfer, and a low-to-high
transition on the LRCLK signifies the beginning of the right
channel data transfer (see Figure 27).
In RJ mode, the data is right-justified, LSB last, with the LSB
placed in the last BCLK period preceding the transition of LRCLK.
A high-to-low transition of the LRCLK signifies the beginning
of the right-channel data transfer, and a low-to-high transition
on the LRCLK signifies the beginning of the left-channel data
transfer (see Figure 29).
Left-Justified (LJ) Mode
In LJ mode, the data is left-justified, MSB first, with the MSB
placed in the first BCLK period following the transition of the
LRCLK. A high-to-low transition of the LRCLK signifies the
beginning of the right-channel data transfer, and a low-to-high
transition on the LRCLK signifies the beginning of the left-
channel data transfer (see Figure 28).
