ADS8168: SPI debug pattern

Part Number: ADS8168


I'm trying to test the SPI communication with the ADS8168 by enabling the debug mode for SDO capture. According to the documentation, if the DATA_VAL bit in the DATA_CNTL register is set the ADS8168 should output the fixed binary pattern 1010 0110, however, in my tests it seems that the output binary pattern is 1010 0101 instead. This result seems to be consistent, and considering that other operations such as writing and reading other registers seem to be working fine, my question is whether I am missing something or if the SPI communication is actually working as it should, and the unexpected debug pattern is just an error in the documentation. Any comments are appreciated.
