is it possible to keep the rtc of a mcf5445x alive by powering it from a battery? what is the supply current on pin VDD_RTC? may VDD_RTC be 1.5 Volt when the other supplies are 0V?
Does anyone have any comments on this thread?
From the manual review, I think, RTC in MCF5445x cannot be run by powering it from a battery. Please confirm it.
Same question here.
