__HAL_UART_GET_FLAG macro

specifies the UART Handle. UART Handle selects the USARTx or UARTy peripheral (USART,UART availability and x,y values depending on device).

specifies the flag to check. This parameter can be one of the following values: @arg UART_FLAG_CTS: CTS Change flag (not available for UART4 and UART5) @arg UART_FLAG_LBD: LIN Break detection flag @arg UART_FLAG_TXE: Transmit data register empty flag @arg UART_FLAG_TC: Transmission Complete flag @arg UART_FLAG_RXNE: Receive data register not empty flag @arg UART_FLAG_IDLE: Idle Line detection flag @arg UART_FLAG_ORE: Overrun Error flag @arg UART_FLAG_NE: Noise Error flag @arg UART_FLAG_FE: Framing Error flag @arg UART_FLAG_PE: Parity Error flag
