Hi cdixon,

Try the following post if you still haven't been able to solve your problem.

Beware that you can only use one of the two buttons SCU WKUPSEL register does not allow you to select more than one. For documentation, check out

http://www.st.com/mcu/devicedocs-STR912FW44-101.html

. The first three pdfs are your most valuable information source.

However, I am also facing some side effects problems, but you can get a starting idea of how to make use of your push buttons.
