PDR_ON effects to VBat?

Datasheet says Yes, but as we tested, RTC still runs (hold data after disconnected power), no matter what state of the pin is.

Thanks for any suggesstion!

Have you measured the current consumption from VBAT under all conditions?

IMO it's not VBAT as such which is affected by PDR_ON, but the VBAT-VDD switch.
