Table 12 Audio Data Input Format
Note:
1.
In all modes, the data is signed 2's complement. The digital filters always input 24-bit data. If
the DAC is programmed to receive 16 or 20 bit data, the WM8718 pads the unused LSBs
with ZEROS. If the DAC is programmed into 32-bit mode, the 8 LSBs are treated as zero.
