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. |
