Implement an Assembly Language Application on ATtiny104

This application note is intended to implement an assembly language application on ATtiny104. The steps are:

1. Create a new Atmel Studio or IAR project.
2. The compiler will provide the start-up code.
3. Implement the main function as:

   int main(void)
   {
   	while (1) {
   	}
   }

4. Implement other assembly functions in .s files.
5. Call the assembly functions in the main function.
6. Inline Assembly Language can also be used.
