PIC16: How does one enter sleep mode using C?

Question

The datasheet of my PIC16 refers to the "SLEEP instruction". I'm programming the PIC16 in C using MPLAB X and the XC8 compiler.

How can I execute a SLEEP instruction on my PIC16 using C?

You should try looking into the user manual of your compiler, next time. Page 276. — abdullah kahraman, Nov 02 '12 at 15:42

You can use this macro:

SLEEP();

This macro is used to put the device into a low-power standby mode.

If you search for the definition of SLEEP() in the header files, you'll find:

#define SLEEP()     asm("sleep")

asm(); is a statement which allows you to inline assembly instructions into your C code.

we should make sure to turn off WDT in that case. – Standard Sandun Nov 02 '12 at 16:30

@sandundhammika True, unless we purposely want the WDT to wake the PIC and resume execution when the time-out occurs – m.Alin Nov 02 '12 at 16:41
