 If event is not handled (or handled but EVENT register not cleared), will it go above 1 or is it binary? 
 In other words, can the value be used to detected missed interrupts (in case a softdevice is running)

&lt;p&gt;Side note: In the nRF52832 Product Specification v1.4&lt;br /&gt;Section 15.8.1 Peripheral Interface, Interrupt clearing&lt;br /&gt;&lt;br /&gt;Explains why a volatile dummy read is required after clearing an interrupt.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;But to the larger question: How do I detect missed events or can they be detected?&lt;/p&gt;
&lt;p&gt;I don&amp;#39;t think you can detect dropped events directly through the EVENT (or TASK) registers.&lt;/p&gt;
&lt;p&gt;You would have to infer the drop due to other register or state context.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
