System OFF wake up with internal RC RTC

[peter]

Hi All,

I am working in the sleep mode with system off and wake up with internal RC RTC. It function well when connected to EV board...

I see the "Emulated System OFF mode" in reference manual. Any step I need to do to make it work on my PCBA also??

Thanks in advance.

You can do System ON wake up with an internal RTC TIMER But System OFF will not be possible.

In system off mode, all clock sources and peripherals on the chip are turned off, please see this question for more information.

In debug interface mode, System OFF will be emulated to facilitate debugging of the device while in System OFF. In Emulated System OFF mode the power consumption will be high, it is not supposed to be used in normal operation.
