https://devzone.nordicsemi.com/f/nordic-q-a/58378/power-management-clarificationHi, I want to test the power managment on the nRF52840. I plan to make a simple test application that enter in sleep/systemoff mode every, let&#39;s say, 1 minute. After wake up it&#39;ll performs some simple tasks and then enter again in sleep/systemoff modeen-USTelligent Community 13Thu, 27 Feb 2020 13:33:37 GMThttps://devzone.nordicsemi.com/thread/236874?ContentTypeID=1Thu, 27 Feb 2020 13:33:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fedd4641-f49d-4d8e-b45a-3f90d13a80e9Jose Forno<p>Thanks for your answer.

Correct.</span></p> <p><span>2. Yes,&nbsp;nrf_pwr_mgmt_run puts the MCU into SystemON Idle, a sleep-state where all peripherals are available and the CPU sleeps until woken by any interrupt.&nbsp;</span></p> <p><span>3.&nbsp; No, there are only three power states; SystemON, SystemON Idle, and SystemOFF.&nbsp;&nbsp;There is also a sub-state in SystemON Idle called Constant Latency where the HFCLK is kept running in order to speed up the wake-up time of the CPU and peripherals, but this feature is seldom used as it consumes a lot of power.
