 Is there a software way to detect if an external 32kHz XTAL is connected to the nRF52 or not ? 
 So it could possible to select the internal RC oscillator instead of the external source by calling nrf_clock_lf_src_set() with the appropriate</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 07 May 2018 12:42:45 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/34057/hardware-external-32khz-xtal-detection" /><item><title>RE: Hardware External 32kHz XTAL detection</title><link>https://devzone.nordicsemi.com/thread/131198?ContentTypeID=1</link><pubDate>Mon, 07 May 2018 12:42:45 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:0160ade0-219c-4b74-9ba3-4c1aecb9cbb7</guid><dc:creator>H&amp;#229;kon Alseth</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;

&lt;p&gt;Unfortunately, there is no option to detect if there&amp;#39;s a 32k xtal present on the XL1/XL2 pins.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
