Pin 33 is an input pin used to alert the firmware that it should switch to analogue signal instead of digital. You can take it directly to ground or if it makes you feel better use a res. If you do choose to use a res, make it a low value less than 1K to ensure the pin 33 has been taken low enough to be seen as a "logic zero" by the control cir's.
