Resolved! Interrupt routine not calling in LPTIMER of STM32H735VGH
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() ?
