Interrupt routine not calling in LPTIMER of STM32H735VGH

[Pavani]

In LPLTIM_IER register, the ARRMIE bit is SET by software and LPTIM_ISR register the bit ARRM bit is SET by hardware but this LPTIM4_IRQHandler() function is not calling.

what might be the reason of not calling this function LPTIM4_IRQHandler() ?

Hello @Pavani ,

you probably forgot to configure the interrupt in the NVIC.

Look at timers examples to help you.
