We use AM3354 (ZCZ package) and like to change the RTC power from internal to external power, either battery or power supply.
So we can have RTC running when the system was shunt-down.
I understand that RTC_KALDO_ENn pin shall be pull HIGH (1.8V).
I like to confirm about CAP_VDD_RTC pin.
Did it requires to supply with 1.1V too for RTC using external power? Thank you.
