timer break interrupt
hi im using stm32g474vet6 mcu , in that i am using tim1 for pwm generation , for protection im enabling all the 7 comparators and exrernal break input pin for pwm shutdown. comparator configuration and dac settings are correctly done.i dont know why the tim_bkin interuppt is not shutdown the pwm by mcu hardware itself.
by software im doing like this comparator output is detected and pwm is shutdown. but by hardware external input and internally comparator hardware is not working
