PCH #fuses vs. MPLAB Configuration Bits |

I just used a Microchip ICD2 to program a chip with a program I wrote and compiled in PCW. The C source has a #fuses directive, but I started wondering: does the #fuses directive have any effect on the program at all if I program the device using MPLAB? Or, does MPLAB's "Configuration Bits" dialog take care of that? That is, is the #fuses directive purely a CCS ICD construct?

The compiler puts the settings in #fuses statement into the config word
section of the HEX file, when you compile your source program.
When you use MPLAB to program a PIC, it reads the config bit settings
from the HEX file and loads them into the "Configuration Bits" dialog. |
