STM32F302VCT6 - PC14 -> RTC_OUT_CALIB ?

I would like to set a 1Hz signal on the PC14 (RTC_OUT_CALIB). I have found a manual in document AN3371 (see picture in appendix). The code is also in the appendix. Unfortunately, nothing happens on the PC14 but the RTC works. If anyone has any idea what else to add here, thank you, greetings, SF

You cannot use PC14 as RTC_OUT_CALIB, only PC13.

If that does not work, read out and check/post the RTC registers content.
