Re: [PIC] PIC18F24Q10 header #define

It defines a macro symbol called NVMADRH

And happens to replace it with the text that is identical to the name.

In other words, next to nothing.

It permits the symbol to be checked for by other preprocessor directives.
And allows the name to be changed, I suppose.

I always found the microchip headers to be a bit cryptic.
