PA8/CK_OUT0 alternate function mapping

Hi,

I’d like to map CK_OUT0 to PA8. I configured CKOUT0SEL and PA8 to AF PP mode. But I’m missing other steps to map finally CK_OUT0 function to PA8. I haven’t found this specific CK_OUT0 mapping in MCU User manual. Can you help, please?

Thanks

This is all you need to do.

rcu_periph_clock_enable(RCU_GPIOA);
rcu_ckout0_config(RCU_CKOUT0SRC_CKSYS);
gpio_init(GPIOA, GPIO_MODE_AF_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_8);
