Even when using MPLAB, specifying the CONFIG fuses directly in your source
code provides a few advantages to letting MPLAB set them for you.


Not in any particular order:

1. Your selections are used, not MPLAB's defaults. You're guaranteed to get
what you expect.

2. For some of your programs you may want to use different options than for
other programs. By specifying the fuses in the source code, you don't have
to remember to change the default MPLAB settings before programming. (It's
just too easy to forget to do that.)

3. Your selections provide documentation right in the code as to how *you*
want the CONFIG fuses to control processor operation. (All of the fuse
options are defined in the standard Microchip include files so they're
fairly easy to interpret.)
