 Does this mean that if I install and active a timer interrupt, where the interrupt routine places the system into this sleep state at the end each time, that I get 2.6 uA in between interrupts</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 26 Jun 2014 09:49:43 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/2920/current-draw-in-system-on-mode-idle-with-timer-interrupt" /><item><title>RE: Current draw in System On Mode (Idle) with timer interrupt?</title><link>https://devzone.nordicsemi.com/thread/11107?ContentTypeID=1</link><pubDate>Thu, 26 Jun 2014 09:49:43 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:c3c21522-7696-475a-8eec-c2b276739d0b</guid><dc:creator>H&amp;#229;kon Alseth</dc:creator><description>&lt;p&gt;If you use any of the high-speed timers, such as TIMER0/1/2, these will require the 16M clocktree running, which will add 470 uA to your sleep current, as stated in chapter 8 in the PS (8.3 and 8.1)&lt;/p&gt;
&lt;p&gt;Using the RTC (via the app_timer module for instance) instead will give you a power consumption close to the number that you&amp;#39;ve stated, as this only requires the 32.768 kHz clock source.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
