UART1_SR_RXNE = 0;This bit is set by hardware when the content of the RDR shift register has been transferred to the
UART_DR register. An interrupt is generated if RIEN=1 in the UART_CR2 register. It is cleared by a
read to the UART_DR register. In UART2 and UART3, it can also be cleared by writing 0.
0: Data is not received
1: Received data is ready to be read.
