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. |
