RTC does not have hardware to start or do any other internal state change upon external triggers.

I want to create similar function to LPTIM One shot mode

that external pulse trigger (very short) cause one output pulse (width of 1 second)

RTC does not have hardware to start or do any other internal state change upon external triggers.

We can't used EXTI to activate RTC down counter?

Yes you can, if you don't care about the latency/jitter this involves. In the interrupt, you can of course set RTC to whatever you want.

I don't know what do you mean by "RTC down counter" - the wakeup facility.
