TIM10 compare output is PF6, But I want to use PF7

  I used STM32F429ZI

I make this sorce code

GPIOF->MODER |= 0x00002000; //PF6 AF mode

GPIOF->PUPDR |= 0x00002000; //PF6 pull down

GPIOF->AFR[0]|= 0x03000000; //PF6 AF3(TIM8..11)

It is good work. ( PORTF6 IDR is good working)

But I want to use PF7, so change sorce code

GPIOF->MODER |= 0x00008000; //PF7 AF mode

GPIOF->PUPDR |= 0x00008000; //PF7 pull down

GPIOF->AFR[0]|= 0x30000000; //PF7 AF3(TIM8..11)

But it is not work (PF7 IDR is not working)  why?

PF6 -> PF7 can not?

Just only use PF6?

Only few of pins can be used for a certain function (or maybe only one). Press CTRL and click on the pin which is selected by default (PF6 in your case). All other possibilities will be coloured in blue.

PF7 would need to use TIM11, no relationship to TIM10 available
