Thanks for the offer, certainly will do. I'll open up that ARM spec and the SA-1110 datasheet again tomorrow and see if I can't apply some of your tips. Charles and Bruce Ellis also responded off-list with tips of their own. I'll see if these tips combined get me any further, otherwise I'll just accept the offers and bug you guys some more ;). --Devon
