Yes, I know. I explicitly removed this code because of two reasons:

a) My basic testing platform was the esd mecp5123 board.

b) I did some quick tests on the MCP5121ADS with this code (without
   this ADS specific chip-select handling) and didn't see any error.

So I suggest to add the code as is for now. Such board specific routines can 
be added later on when really needed.

Best regards,
Stefan
