I am designing my board with TPS65910A3 on AM335X system. My design reference to the Starter Kit Board of AM335x.
I need RTC go on when system powered off.
1.If I want to use AM335x RTC ,what should I do?
2.And If I want to use TPS65910A3 , just put a back battery on TPS65910A3 27th pin. right?
3.The internal 32K RC of TPS65910A3 ,how accurate is the RC?
And which is better between RC oscillator and crystal oscillator?
Thank you .
Best Regards.
