Sleep Mode Setup in XC Compilers

The MPLAB^® XC compilers offer macros to invoke Sleep mode. Below is an example for each C compiler showing the sleep macro function for that compiler. Please note that they are case sensitive.

 /*******************************************************************************
  *          Enter Sleep mode
  * This macro issues the SLEEP instruction to shut down the system oscillator
  * and enter low power operating mode.
  ******************************************************************************/

#if defined(__XC8__)
        SLEEP();

#elif defined(__XC16__)
        Sleep();
        /* or */
        __builtin_pwrsav(0);
        Idle();

        /* or */
        __builtin_pwrsav(1);

#elif defined(__XC32__)
        /* Wait instruction */
        _wait();
#endif
