As long as the main power supply is available, the real time clock will run. Thisconfiguration may be suitable for battery powered systems with a non-removable main battery, or forsystems without the requirement for a real time clock.Toradex AG l Altsagenstrasse 5 l 6048 Horw l Switzerland l +41 41 500 48 00 l www.toradex.com l info@toradex.com Page | 28

Please refer section 6.5.1 for more information to the bootmodes.Important: The 12V_Main voltage needs to ramp up continuously if the boost converter is enabled.Otherwise, the boost converter may be damaged during voltage drops.Toradex AG l Altsagenstrasse 5 l 6048 Horw l Switzerland l +41 41 500 48 00 l www.toradex.com l info@toradex.com Page | 29
