Using TIM9 for PWM input

Which IRQ do I need to use ? I don't see any IRQ related to TIM9 at stm32f4xx_it.h.

TIM8 can also do PWM input - which IRQ do I need to use there ?

void TIM8_BRK_TIM12_IRQHandler(void); /* TIM8 Break and TIM12 */

void TIM8_UP_TIM13_IRQHandler(void); /* TIM8 Update and TIM13 */

void TIM8_TRG_COM_TIM14_IRQHandler(void); /* TIM8 Trigger and Commutation and TIM14 */

void TIM8_CC_IRQHandler(void); /* TIM8 Capture Compare */

Thanks in advance

I looked in the vector table and it seems as of TIM9 cannot generate interrupts. Is this correct? I would expect that TIM8 would handle PWM input in its CC interrupt, but that does not work. Any ideas?
