That was all I was asking for and it was extremely informative. I didn't know that if you used the internal clock you automatically got those GPIO ports freed and got one freed with an external clock. There were good definitions of why when when to use the different clocking options and what those delays are for. It answered all my questions. Thanks again.
Telecommando, thank you too. I didn't really grasp the difference between full swing and low power crystals and now I am going to do some more research on that topic.
