Use STM32L031F4P as Programmable Voltage Detector?

[Prajnyajit]

I am using STM32L031F4P.

I want to use it Programmable Voltage Detector to detect the voltage of its power supply.

I am not finding any library to use.

I want to have some coding help and its library file.

The closest example I see is https://github.com/STMicroelectronics/STM32CubeL0/tree/master/Projects/NUCLEO-L031K6/Examples/PWR/PWR_PVD.

Read the description of PWR module, PVD section. Write 5 lines of code/simple C instructions: set 2 registers (PWR->CR, EXTI->IMR), wait for PVDO, if needed - enable PVD interrupt in EXTI, then in NVIC. That's all.
