It works by its author having read the applicable documents (a C
textbook, and the particular compiler's documentation) and learning from
them. I suggest you try that, too.

There's nothing magical about it. See the C textbook on what (unsigned
char *) would mean, and the compiler documentation on the meaning of
'xdata'. See the rest of the source code to understand where
Scratch_Flash_Addr might be coming from.

By reading the C textbook.
