https://devzone.nordicsemi.com/f/nordic-q-a/38310/rtc1-interrupt-not-triggeringI&#39;m having some trouble getting interrupt from RTC1. I&#39;m initialising as follows. I have an interrupt function as follows. I&#39;m using the gcc_startup-script. We&#39;re not using the SDK. I&#39;m not getting any errors from SoftDevice and everything seemsen-USTelligent Community 13Mon, 10 Sep 2018 12:42:10 GMThttps://devzone.nordicsemi.com/thread/148021?ContentTypeID=1Mon, 10 Sep 2018 12:42:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:51117a50-d78d-4a3d-919d-0bc3db986bd3obbe<p>Thanks for your answer. I&#39;m curious what the reasoning is that you need to both enable the interrupts and set the flags? In other architectures I&#39;ve used you only needed enabling the specific interrupt you were interested in (even if the interrupt routine was the same for multiple sources).</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/147858?ContentTypeID=1Fri, 07 Sep 2018 18:49:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5a244d05-8d9f-41b1-a917-3af9414a8f3bTurbo J<p>INTENSET set which events can trigger the RTC1_IRQ.</p> <p>NVIC_EnableIRQ() determenes wheter the RTC1_IRQ line can interrupt the CPU core at all.</p> <p>There are cases when you don&#39;t want specific interrupts to occur.</p> <p>Remember to use NVIC_SetPriority(), this is required for softdevice - the default priority zero is not available for application.</p><div style="clear:both;"></div>
