hi all,   I'm new in the forum and I am experiencing a problem of ISR , which doesn't  happen for TIM12 while, with same ch1 configuration register and same pwm signal input,  set the ISR calling for TIM9, as expected.  I am quite surprised of this behaviour and I have checked the TIM9 and TIM12 register configuration  but I cant found any difference .  I am about to check if there is any errata which may affect the TIM12 functionality: not yet done at the moment.  do you have any suggestion?  I am new to stm32 device and maybe someone can give me some tips on what to check and debug(keil V5)  .
