In order to keep time between given events, I would recommend using the RTC as a time-keeper.</p> </li> <li> <p>The RTC will keep running until it hits it&#39;s set value in RTC2CMPx if field CompareMode in register RTC2CON is set to &#39;11&#39;. If this field is set to &#39;10&#39;, the timer will not clear.</p> </li> </ol> <p>This is regardless of wakeup-source from &quot;Standby Mode&quot;.</p> <p>If you look at the nRFgo SDK, there&#39;s a HAL layer written for the RTC located here:</p> <pre><code>\nRFgo SDK 2.3.0.10040\source_code\hal\nrf24le1 </code></pre> <p>Cheers, Håkon</p><div style="clear:both;"></div>
