Hai Support,
I am using AM3354 in my design and I have few questions regarding the RTC functionality. I see that AM335x evaluation board uses RTC crystal connected to the Processor. But when the power is off there is no backup power to the RTC domain and the time and date contents cannot be actively incremented. It will remain at the old place only after power on. But I see that the RC oscillator on the PMIC can be used for the RTC functionality and it even has battery backup connected to it. If I am using RTC from PMIC do I need to connect Crystal to Processor? There is accuracy issue with the RC oscillator which will not provide the accurate time. I am not sure of what will be difference when I use RC oscillator or crystal. If any details can be provided on this then it would be helpful.
Regards,
Erfan
