This field is mandatory: it is the main program file (Eg: the project's root source file), the first that will be compiled.
Additional files to link:
By default PMP links all files that are compiled and assembled, but if some assembler or object files have to be added, they may be listed here.
A .asm file will be assembled if needed, an object file will be passed directly to the linker.
This feature may be used to track the project version.
The values may be linked to the processor's IDLOC features, if needed.
The values define PROJECT_VERSION_xxxx system pseudo-constants.
Free memo to note some useful information about the project.
