  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?
