can timer interrupt wakeup STM32 from stop/Sleep mode ?

hello I am using STM32F030F4 microcontroller, question is regarding low power mode. For that i want to wake from stop mode using RTC. As RTC programmable mode is not there in STM32F030F4, So what is the best way to awake from stop mode.

Or any other way in STM32F030F4 microcontroller, to awake from low power mode. and I am using timer in my application.

In my application, I need to awake up with in 2 seconds regular intervals when it goes in stop mode. can you share sample code for RTC's calender and using its internal Alarm A for waking up?

I am using STM32F030F4P6I am just looking for an example code where RTC gives a periodic alarm every 1 second (or any other time period)
