Built the single step circuit and followed these step and checked /IRQ if it was high all the time. Well it wasn't. It went low after step 6 but the SEI instruction had then been executed so an interrupt could not happen...I read CRA (to reset the FLAG) in the beginning of the initialisation of the RTC...it worked.
