I remember struggling with this chip a year ago and this page really helped me. Peter is a good teacher....he includes nice explanations and student projects with shortcomings and improvements explained. My first app with it drove me nuts! After figuring out this chip the first time it becomes almost a no-brainer. BTW, the extra memory on the 1302 comes in handy with small PICs, too.
