Appendix A. Library Functions

The functions and preprocessor macros within the standard compiler library are alpha-

betically listed in this chapter.

The synopsis indicates the header file in which a declaration or definition for function

or macro is found. It also shows the function prototype for functions, or the equivalent

prototype for macros.

__CONFIG (BASELINE & MID-RANGE DEVICES)

Synopsis

#include <xc.h>

__CONFIG(data)

Description

This macro is used to program the configuration fuses that set the device’s operating

modes.

The macro assumes the argument is a16-bit value, which will be used to program the

configuration bits.

16-bit masks have been defined to describe each programmable attribute available on

each device. These masks can be found in the chip-specific header files included via

<xc.h>.

Multiple attributes can be selected by ANDing them together.

Example

#include <xc.h>

__CONFIG(RC & UNPROTECT)

void

main (void)

{

}
