hi.....what this function performs _CONFIG...... is this an intrinsic fuction in keil IDE
How easy do you think it was for people on a Keil forum to guess that you meant something you found in PIC source code compiled by a very much non-Keil compiler?
The _CONFIG() (whatever it internally is to the compiler) informs the linker about configuration fuses for the processor, i.e. if it should use a RC or a crystal oscillator, if the watchdog should be enabled or not, ...
But guess what: A Microchip compiler is probably best documented on a Microchip web page, and questions are probably best asked on a Microchip-oriented forum...
Now I'm about to call Volkswagen and ask them which break fluid I should buy to my Volvo.
