Reading a configurable setting from external HW into software ?

Hi,

 

I'm building a customized board based on the SHARC 21469 DSP.

 

Is it possible to hook the DAI up to an external pull up resistor with a switch and read the setting of that switch (0 or 1) from the software?

If so, I would like to know how exactly it should be done.

 

If there's an easier or better way of accomplishing the above (i.e. reading a configurable setting from external hardware), I would like to know more about that as well.

 

Thank you.
