STM32L475 RTC interrupt for every 1s

I want to configure the RTC interrupt for every 1s in L475. Since all RTC interrupt are routed through EXTI, is it possible to generate the interrupt periodically without depending on external signal?

Something like second interrupt (SECIE) in STM32F103.

Hello @PBala.2​,

You can refer to the firmware example "RTC Alarm" under this path :

\STM32Cube\Repository\STM32Cube_FW_L4_V1.17.0\Projects\NUCLEO-L476RG\Examples\RTC

Thanks @Mohamed Aymen HZAMI​  Will look into it :-)
