https://devzone.nordicsemi.com/f/nordic-q-a/39284/pwm-during-sleep-modeHello, I am using the module nRF52840 and nRF SDK 15.2.0. I would like to start a PWM, going to sleep mode and still having the pwm running. I tried combining the pwr_mgmt example and pwm_library example but when i enter in shutdown mode, the PWMen-USTelligent Community 13Tue, 09 Oct 2018 10:50:36 GMThttps://devzone.nordicsemi.com/thread/152189?ContentTypeID=1Tue, 09 Oct 2018 10:50:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7db40e72-ce8e-4bf9-89b4-07a5b9814ec8Vidar Berg<p>Hello,</p> <p>1. It&#39;s not possible to run the PWM in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/power.html?cp=2_0_0_4_2_2#unique_712808887">System OFF</a> mode. All clock sources are powered down in this mode. However, the CPU will automatically enter System ON idle mode as long as you call the __WFE (or&nbsp;sd_app_evt_wait() if softdevice is enabled) from your main loop. This will result in the lowest possible current consumption with PWM enabled.&nbsp;</p> <p>2. Yes, System ON mode</p> <p>3. Around 500-1000 uA depending on frequency and load</p> <p>4. Significantly lower current consumption, but with&nbsp;lower accuracy and max. frequency.</p><div style="clear:both;"></div>
