STM32C011F4 - Is it possible to wakeup periodically from Stop mode by RTC AlarmA

[iotengtr]

I am using STM32C011F4 mcu on my project. 

I want to send my device to sleep mode with HAL_PWR_EnterSTOPMode(). 

STM32C011F4 does not have build-in Walke-up option in RTC driver.

So, I'd like to learn if it is still possible to use AlarmA to periodic sleep/wake-up sequence. 

Any help is appreciated. 

Thanks in advance.

Hello @iotengtr according to the table 93 of the RM0490, you can use the ALARM A interrupt can wake-up  only from Sleep and stop mode (if RTC clock source is LSI or LSE).

To understand how to Configure it, you can use the description of the same reference manual.
