MCF52259 RTC problems

I am still trying to get the RTC of the 52259 CPU running, but still without luck. I can write the time in the registers but the time does not advance.

 

It's not clear to me how the 52259 RTC has to be programmed to make it work. The reference manual doesn't really help here either. I'm sure a particular sequence has to be followed but I don't really understand the explanation in the manual.

 

Any help is appreciated.
