 I&amp;#39;m working on a legacy program using nRF52833 and nRF5 SDK using SoftDevice S113. 
 My application has two input GPIOs, and both can wake the MCU from System OFF. The app should be able to determine which GPIO (rising edge) woke it (let&amp;#39;s say GPIO</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 02 Dec 2022 06:23:30 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/93885/nrf52833-latch-register-validity-after-wake-from-system-off" /><item><title>RE: [nRF52833] LATCH register validity after wake from System OFF</title><link>https://devzone.nordicsemi.com/thread/398674?ContentTypeID=1</link><pubDate>Fri, 02 Dec 2022 06:23:30 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:2999a2ed-533b-4f30-b768-42f4849853a1</guid><dc:creator>Marco R</dc:creator><description>&lt;p&gt;Thanks for confirming!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: [nRF52833] LATCH register validity after wake from System OFF</title><link>https://devzone.nordicsemi.com/thread/396190?ContentTypeID=1</link><pubDate>Thu, 17 Nov 2022 12:12:22 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:03e1b97a-b50d-4044-877d-180ad5215239</guid><dc:creator>Sigurd</dc:creator><description>&lt;p&gt;Hi Marco,&lt;/p&gt;
[quote user=""]Could you help confirm the LATCH register is still valid after waking from System OFF[/quote]
&lt;p&gt;Yes, LATCH register is still valid after waking up from System OFF.&lt;/p&gt;
[quote user=""]and this is the recommended approach for the App to know if there was GPIO activity on specific pins while waking?[/quote]
&lt;p&gt;Yes, absolutely, this sounds like a good approach for that.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;BR,&lt;/p&gt;
