On the STM32F103C8 chip I can use the PA9 default alternate function to use either USART1_TX or TIM1_CH2 on that pin depending upon which peripheral is enabled.
If both peripherals are enabled and I am using PA9 as USART1_TX, does this preclude me from using TIM_CH1, TIM_CH3, or TIM_CH4? This assumes that TIM_CH2 is disabled:
TIM1 MOE =1
OSSR = x
CC2E = 0
CC2NE = 0
I pretty sure the answer is "Yes", but would like confirmation.
