 I have been developing an application for some time and everything has been running smoothly, until recently testing it and finding out some inaccuracies. 
 In the application, among others, I use a high priority (IRQ = 3) 16MHz timer to</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 21 May 2024 12:42:16 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/111291/timer-does-not-count-time-accurately" /><item><title>RE: Timer does not count time accurately</title><link>https://devzone.nordicsemi.com/thread/485121?ContentTypeID=1</link><pubDate>Tue, 21 May 2024 12:42:16 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:202772b6-1262-4e4a-8605-5720d659f45f</guid><dc:creator>Vidar Berg</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;If you have done so already, please try to&amp;nbsp;enable the&amp;nbsp;&lt;a title="64 MHz crystal oscillator (HFXO)" href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/clock.html?cp=5_0_0_4_3_0_0#concept_rmw_c5y_2q"&gt;crystal oscillator (HFXO)&lt;/a&gt;&amp;nbsp;and see if that helps. Otherwise, the TIMER will run off the internal RC oscillator (HFINT) which has a worst case tolerance of -+ 8 %.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
