Hi, there is an evaluation board from Keil and we used the RTC, it seems to work without problems there. Information about the board can be found here: http://www.keil.com/mcb2130/ There is also a link to the schematics somewhere there.

I understand that there is an error in that sch.
The configuration should be
(see in fixed font!):
