Can we output the RTC calib on pin PE3 on STM32L0 ?

[STM32L0Fan]

i have a STM32L0VZ (UFBGA100) and I would like to know if I can ouput the RTC Calib on this PIN ?

Thank you very much

What stm32l0 exavctly? I also do not see RTC calib mentioned, do you mean RTC clock? PE3 does not have MCO capability, but TIM22_CH1 capability. Perhaps you can clock TIM22 from RTC and output RTC-CLOCK/2

Hello @STM32L0Fan​ ,

You should check the reference manual for the chip you have. For example, for STM32L0x1, here are the possible output mappings:
