void UART3_ClearFlag ( UART3_Flag_TypeDef UART3_FLAG )

UART3_FLAG_RXNE: Receive data register not empty flag.

Note:

PE (Parity error), FE (Framing error), NF (Noise error), OR (OverRun error) and IDLE (Idle line detected) flags are cleared by software sequence: a read operation to UART3_SR register (UART3_GetFlagStatus())followed by a read operation to UART3_DR register(UART3_ReceiveData8() or UART3_ReceiveData9()).

RXNE flag can be also cleared by a read to the UART3_DR register (UART3_ReceiveData8()or UART3_ReceiveData9()).

TC flag can be also cleared by software sequence: a read operation to UART3_SR register (UART3_GetFlagStatus()) followed by a write operation to UART3_DR register (UART3_SendData8() or UART3_SendData9()).
