 I would like to wake the nRF52840 SoC from sleep via a GPIO High Pulse input. 
 What is the minimum allowable pulse period do I need for it to successfully wake up the nRF52840?? 
 
 Thanks and regards.</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 15 Oct 2020 12:49:19 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/67222/nrf52840-wake-on-gpio-timing-requirements" /><item><title>RE: nRF52840 Wake on GPIO timing requirements</title><link>https://devzone.nordicsemi.com/thread/275093?ContentTypeID=1</link><pubDate>Thu, 15 Oct 2020 12:49:19 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:6c37d843-1a20-41f2-91c3-d2aed8de5c42</guid><dc:creator>Simonr</dc:creator><description>&lt;p&gt;Hi&lt;/p&gt;
&lt;p&gt;You can check out the Device startup times section in the product specification &lt;a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fpower.html&amp;amp;anchor=unique_1094698514"&gt;found here in the Infocenter&lt;/a&gt;. For reference, the minimum pulse between events is one clock pulse of 16MHz (0.0625µs).&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Simon&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
