STM32CubeMX version 6.0.1 defines a wrong AF function for PC8 and TIM3_CH3 for STM32F030C8
STM32CubeMX in version 6.0.1 does generate an invalid alternate function setting for PC8 and TIM3_CH3 for STM32F030C8. The datasheet states that this should be alternate function 0. See https://www.st.com/resource/en/datasheet/stm32f030c8.pdf. A look into the relevant GPIO-STM32F051_gpio_v1_0_Modes.xml file reveals that the signal description for TIM3_CH3 maps to GPIO_AF1_TIM3 instead of GPIO_AF0_TIM3 in case of GPIO pin PC8.
