I used STM32F429ZI
I make this sorce code
GPIOF->MODER |= 0x00002000; //PF6 AF mode
GPIOF->PUPDR |= 0x00002000; //PF6 pull downGPIOF->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 downGPIOF->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
