There are also useful libraries developed on top of these HW peripheral blocks, notably modules provided by Nordic as part of nRF5 SDK (e.g. <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.0.0/lib_timer.html?cp=4_0_0_3_43">popular <code>app_timer</code> module which allows you to run multiple &quot;virtual&quot; timers on top of single RTC instance</a>).</li> </ol><div style="clear:both;"></div>
