The rotate instruction on the LED register will work. You will be able to see
if you did it right by using the simulator in MPLAB.

I covered this in detail during class on Friday. You need to check each
button. If either one is currently pressed then goto a special location,
wait for all buttons to be released, then goto the initialization (startup)
code for the program. If neither was pressed, just return back to the

Start from the button.asm code I posted to the website and adjust the time to
the value required for this lab. The right place to adjust will be easy to
find if you read the comments in the code.
