Just out of curiosity, can I use the 627a instead of the 84(a) and keep the programming the same? I am using picBasic pro compiler. Secondly, if I don't use xtal, does the 627a automatically uses it's intrc if i make this selection on epicwin....if not what is the code to tell the 627a to use intrc for both picBasic and picBasic Pro.

Thank you
