On my very first post i linked the Design guide.

the design guide is different from the datasheet as it gives you vital ISP codes and timing information.

Make sure you are referring to the design guide and not the data sheet.

Unless Nuvaton changed this....

but then again, my project is working... (no offense)

if you are using Picbasic you mind posting some of your code so that some of us may analyze it? I'm sure Jerson can dissect it in his sleep (again no offense)
