Hi to all

I'm an Italian Grant Researcher at Università Politecnica delle Marche and i'm trying to use the evaluation board M52223EVB.
I read some pages of the Reference Manual (MCF52223RM) and the board UG (M52223EVB_UG), but this is the first time i'm trying to program a Microcontroller and i've some problem.
Fortunately, i found the software ColdFire Init, but this didn't solve all my problems. I managed to blink some Led and i understand what resgisters are implied.
My objective now is to blink a led when i push one of the two user button (SW1 or SW2), but i didn't understand what registers i would have to use.

Thanks to all in advance.
