Are you sure that the "the corresponding input pins"
that you are changing are correct??

My best guess is that you are probing the wrong pins
or your code is broken.
Suggestion:
Write a loop [infinite] to read 3 dip switches and
display the results on the three LEDs. Verify by
flipping the swiches.
Then, change the input to 3 McBSP pins. You will know
where to concentrate your debug.

You can get this info from the 6711 DSK help in CCS.
It gives the code for the PAL and much more.
FYI, I have not looked at your code but I have posted
it in case someone else may have the time.
