&lt;p&gt;When waking up on RTC timer there is a «pre tick» event that occurs some time before the actual tick, so that you have time to start the 16MHz clock before the actual tick occurs.
While waiting for the tick, after the pre tick happens, you can enter standby mode to reduce power consumption.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
