Notes

Right Justified mode does not support 32-bit data. If word length xAIFxxWL=11b in Right

Justified mode, the word length is forced to 24 bits.

In all modes, the data is signed 2's complement. The digital filters internal signal paths process

24-bit data. If the device is programmed to receive 16 or 20 bit data, the device pads the unused

LSBs with zeros. If the device is programmed into 32 bit mode, the 8 LSBs are ignored.

In 24 bit I

2S mode, any data width of 24 bits or less is supported provided that LRCLK is high for

a minimum of 24 BCLK cycles and low for a minimum of 24 BCLK cycles. If exactly 32 bit clocks

occur in one full left/right clock period the interface will auto detect and configure a 16 bit data

word length.
