    Keeping RTC running during power down


       Is there a Bat pin that can be used to supply power just to keep the RTC running when main power to the application is removed?


      I notice a VBAT used with the Boost circuit but not sure if this is relevant.


      I would assume there must be provision for this because it would seem wasteful to use an external RTC when one is on board.


      I have lookied through some forums and will do some searches in the meantime.
