https://devzone.nordicsemi.com/f/nordic-q-a/14023/evten-inten-nrf52-rtcThe documentation for EVTEN in the manual, showing the RTC Tasks and Events system (Figure 45) led me to believe that if EVTEN for an event is disabled the EVENT will never get signalled (ie set to 1 in the register) nor will an IRQ get triggered, theen-USTelligent Community 13Mon, 23 May 2016 13:48:33 GMThttps://devzone.nordicsemi.com/thread/53590?ContentTypeID=1Mon, 23 May 2016 13:48:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1b36bb09-e2d2-49ec-8862-efb88da524aaRK<p>I did misread it - I looked at the switch and thought it was a double-pole, single throw, both poles activated by the EVTEN state. Now I look at it again - and it actually makes sense. Thanks.</p> <p>This makes more sense too, seemed wrong to have to enable events as well as interrupts.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/53588?ContentTypeID=1Mon, 23 May 2016 13:44:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0aa30ac3-d415-42c9-907d-f97b1c744be6Ole Bauck<p>Adding link to diagram: <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.0/rtc.html?cp=2_2_0_23_5#concept_eml_dkj_sr">infocenter.nordicsemi.com/.../rtc.html</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/53589?ContentTypeID=1Mon, 23 May 2016 13:44:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:97e92478-46cd-43b6-a467-d52bef7b6148Ole Bauck<p>I believe you misread the diagram.</p> <ul> <li>If EVTEN is set the event flag will be set and event signal will go to PPI.</li> <li>If INTEN is set the event flag will be set and IRQ signal will go to NVIC.</li> </ul> <p>So an interrupt can be triggered even though EVTEN is disabled.
