5.26 __sleep Intrinsic Function

The IAR __sleep intrinsic function inserts a sleep instruction.

Suggested Replacement

There is no equivalent MPLAB XC8 built-in function, but a sleep instruction can be inserted using in-line assembly.

Use asm("sleep");to insert the sleep instruction into the generated code.

Caveats

None

Examples

Consider migrating IAR code such as:

void waitForService(void)
{
    __enable_interrupt();
    __sleep();
}

to MPLAB XC8 code similar to:

void waitForService(void)
{
    ei();
    asm("sleep");
}

Further Information

See the In-line Assembly section in the MPLAB XC8 C Compiler User's Guide for AVR MCUs for more information on in-line assembly and this built-in function.
