sleep mode with RTC only run

[embedholic]

Hi, 

Device should run clock without stopping.

So one of RTC should run.

And device will run NUS peripheral.

In such conditions, i know that i should not use sd_power_system_off. it will stop all the peripherals.

So what is the best way to save power with RTC run and external interrupt wake up the device?

Is it possible to stop all the peripherals except one RTC for clock and external interrupt wake up?

Thanks.
