daughter card input and out ports

Hi,
I am just pojecting one daughter card for DSK6416, and I have one question.
Does anybody now what are input and output ranges of GPIO ports, McBSP0 &
McBSP2. I mean should I consider 3V or 5V. I want to connect SD card and I
have now idea which resistors to choose.

Thanks for consider
