idle instruction C5535

Joachim O.

Hello,

I have the c5535 and want to use the idle2 mode.

In the description (SPRUH87C page 83) stands: executing the "IDLE instruction".

What does this mean.

Have someone an example in c++?

best regards

You'll need to write an assembly language function containing the IDLE instruction, and then you can call it from C++:

        .global _enter_idle
_enter_idle:
        IDLE
        RET

and then you can call it from C++:

extern "C" void enter_idle(void);
if (its_time_to_idle) enter_idle();

Or this works as well.

if (its_time_to_idle)  asm("     IDLE  ");

Hyun

Hi Joachim,
Did you get the example code?
Including defining the IDLE mode configuration?
Thanks in advance,
