Use of PROJECT HEADER can help to make your code more
readable, not least because anyone using your projects knows where
to find key information, such as the model of microcontroller and
the oscillator frequency required to execute the software.
The use of a project header can help to make your code more easily
portable, by placing some of the key microcontroller-dependent data
in one place: if you change the processor or the oscillator used then
- in many cases - you will need to make changes only to the Project
Header.
