What is "one shot function"?

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)

[waclawek.jan]

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?

[waclawek.jan]

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.
