 I need to find the RF Tx power setting of the nRF52840 by reading from the register. I understand this is possible through Jlink and the following command: 
 --memrd &amp;lt;addr&amp;gt; [--w &amp;lt;width&amp;gt;] [--n &amp;lt;n&amp;gt;] 
 I know the addr is 0xABCDEF but what values</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 21 Oct 2019 08:41:50 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/53341/reading-rf-tx-power-with-from-register" /><item><title>RE: Reading RF TX Power with from register</title><link>https://devzone.nordicsemi.com/thread/215845?ContentTypeID=1</link><pubDate>Mon, 21 Oct 2019 08:41:50 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:1876aaab-df66-41bd-abcd-e22b09d36346</guid><dc:creator>Jared</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;Tx power is reset to 0 between each time the radio is active.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;What you are saying surprises me. My understanding is that the RF Tx power is set based on the value of this register.&lt;/p&gt;
&lt;p&gt;Regardless of whether RF is enabled or not, we should be able to read the register value, right?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Reading RF TX Power with from register</title><link>https://devzone.nordicsemi.com/thread/215781?ContentTypeID=1</link><pubDate>Sat, 19 Oct 2019 18:00:16 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:0d072d28-4b84-4688-8aaf-687fe41878f3</guid><dc:creator>Dmitry</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;the radio is active for short periods of time, so you will get zeroes most of the time. You can try to catch the values directly with jlink.exe, by typing command &amp;quot;mem32 0x4000150c,5&amp;quot; until you get non-zero result&amp;nbsp; (nrfjprog halts core when connecting, giving you only one attempt)&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Reading RF TX Power with from register</title><link>https://devzone.nordicsemi.com/thread/215765?ContentTypeID=1</link><pubDate>Sat, 19 Oct 2019 00:55:34 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:5d9c357a-711f-41a4-80c6-e99709d2e7e5</guid><dc:creator>Houman</dc:creator><description>&lt;p&gt;Hi Jared&lt;/p&gt;
&lt;p&gt;All I am getting is zeros!!&lt;/p&gt;

&lt;p&gt;You don&amp;#39;t need to provide the number of bytes to read or the width. You can read the TX power of the nRF52840 by using the nrfjprog memrd:&lt;/p&gt;
&lt;p&gt;&lt;pre class="ui-code" data-mode="text"&gt;nrfjprog --memrd 0x4000150C&lt;/pre&gt;&lt;/p&gt;
&lt;p&gt;best regards&lt;/p&gt;
&lt;p&gt;Jared&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
