Hi, I am trying to use STM32F103C8T6 standby mode and wake it up with wake up feature of RTC, but in CubeMX I don't see that this MCU would have wake up feature under RTC settings. How do I wake up this MCU from standby with RTC and wake up pin?

Hello @JBond.1 

According to the RM0008, The microcontroller exits the Standby mode when an external reset (NRST pin), an IWDG reset, a rising edge on the WKUP pin or the rising edge of an RTC alarm occurs. For the RTC alarm, you can find all details on the section 18 of the same reference manual.

Hope this help 007 :smiling_face_with_smiling_eyes:.

Best Regards.
