Both sources were enabled, I didn't find a register can identify them.

The PWR peripheral should flag the WUP, and I'd expect the RTC to flag itself as the source via the Alarm, or EXTI17

Thx for your reply. In F10x series RTC_CR and NVIC is not powered in standby mode.

But follow your guide, I can compare RTC_CNT and RTC_ALR.
