Hi, 

I'm working on STM32F091 MCU fora the first time and I'm trying to test the USART1 on PF0,1. I have just wrote the code and it works well, but now I can't receive the RXNE interrupt.. the tx line works normally.. if I try to set the port as an input I see the correct logic level on pin so the port works, it seems that the shift register of USART NOT WORK. Any idea?

Thanks.

lorenzo.

You maybe use registry view, which clear status registry flag.
