DIGITAL INPUT & OUTPUT
One I²S (Digital Audio) Port is provided which supports the
following formats: I²S, Left Justified, Right Justified, and PCM
mode.
I²S, Left Justified, and Right Justified Modes
I²S, Left Justified and Right Justified modes are stereo
interface formats. The I2S_SCLK frequency, I2S_SCLK
polarity, I2S_DIN/DOUT data length, and I2S_LRCLK
polarity can all be changed through the CHIP_I2S_CTRL
register. For I2S, Left Justified and Right Justified formats,
