Audioboard (CS42448) running 24 bit

I am currently working with the audioboard from oshpark and I am wondering how you could set the ADCs sampling resolution as well as the DACs resolution to 20/24-bit. As far as I have been able to see (correct me if I am wrong) on this board, there isn't really any built in way of setting the ADC and DAC resolution.

If anybody knows a way to do this it would be nice! Thank you beforehand.
 
If that's the case, I'd assume it is always 24 Bit , and the audio library just takes the upper 16. So you need your own code.
 
Yes, the sample-width settings are for how the signals are transmitted, rather than the native sampling accuracy.

Paul has set the transmission mode to TDM (24 bits in a 32 bit frame), and the extra 8 low-order bits appear at the TOP of the odd numbered channels in the TDM input object, and can be inserted the same way into the output object - making up a full 24 bit sample with a some 8 bit shifting: channel[n] << 8 & channel[n+1] >> 8.

I hope this helps.
