Dear Sir


I would like to confirm the Low power mode.

I refer to the IMX6ULLCEC Rev 1.2.


  1. Entering System IDLE

It is described at P29 Low Power Mode in as following.

"This is a mode that the CPU can automatically enter when there is no thread running."


Is my following understanding correct?

The software does not need to do something explicitly for entering system IDLE mode.



Is it possible to set the condition to enter the system IDLE?


  1. Entering Low Power IDLE


How is it able to enter the Low power IDLE?


  1. Return from IDLE mode


How is it able to return from IDEL mode?



Is it able to return by GPIO port transition?



Is it possible to return from the IDLE mode to the RUN mode by changing the A/D value?

(Is it able to return to RUN mode triggered by A/D?)


Best Regards,
