hello forum ,

I want use only RX of USART1 of my F103
becouse I need TIM1_CH2 function on PA9 in

what happens to PA9 if I enable both USART1 and TIM1 ?
I dont want TX be enabled on PA9 - I want TIM1_CH2 be enabled on PA9
how can I use RX on PA10 and TIM1_CH2 on PA9 ?
does this below code work ?

USART_InitStructure.USART_Mode = USART_Mode_Rx ;
USART_Init(USART1, &USART_InitStructure);

thank you
