Newbie having trouble with IN switches

I have just started using the RABBIT 2000 and I’m stuck with this question.

1). write an assembly language program which makes it possible to control LED DS6 through the switch IN7 and the program should monitor the switch IN7 continuosly. I have looked through the user manuals and their isnt anything about it.

I have looked in the user manual and their is no mention of IN7 switches and I dont know what code would be required to do this. Please help me!!
