Is there a Bat pin that can be sued 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.
Thanks

No need to ask twice answer stays the same.
RTC does not run at power down and cannot be buffered. Use external RTC.

You can use RTC as wakeup in sleep mode -
