Functions
static void	UARTEx_Wakeup_AddressConfig (UART_HandleTypeDef *huart, UART_WakeUpTypeDef WakeUpSelection)
	Initialize the UART wake-up from stop mode parameters when triggered by address detection.
static void	UARTEx_SetNbDataToProcess (UART_HandleTypeDef *huart)
	Calculate the number of data to process in RX/TX ISR.
HAL_StatusTypeDef	HAL_RS485Ex_Init (UART_HandleTypeDef *huart, uint32_t Polarity, uint32_t AssertionTime, uint32_t DeassertionTime)
	Initialize the RS485 Driver enable feature according to the specified parameters in the UART_InitTypeDef and creates the associated handle.
__weak void	HAL_UARTEx_WakeupCallback (UART_HandleTypeDef *huart)
	UART wakeup from Stop mode callback.
__weak void	HAL_UARTEx_RxFifoFullCallback (UART_HandleTypeDef *huart)
	UART RX Fifo full callback.
__weak void	HAL_UARTEx_TxFifoEmptyCallback (UART_HandleTypeDef *huart)
	UART TX Fifo empty callback.
HAL_StatusTypeDef	HAL_MultiProcessorEx_AddressLength_Set (UART_HandleTypeDef *huart, uint32_t AddressLength)
	By default in multiprocessor mode, when the wake up method is set to address mark, the UART handles only 4-bit long addresses detection; this API allows to enable longer addresses detection (6-, 7- or 8-bit long).
HAL_StatusTypeDef	HAL_UARTEx_StopModeWakeUpSourceConfig (UART_HandleTypeDef *huart, UART_WakeUpTypeDef WakeUpSelection)
	Set Wakeup from Stop mode interrupt flag selection.
HAL_StatusTypeDef	HAL_UARTEx_EnableStopMode (UART_HandleTypeDef *huart)
	Enable UART Stop Mode.
HAL_StatusTypeDef	HAL_UARTEx_DisableStopMode (UART_HandleTypeDef *huart)
	Disable UART Stop Mode.
HAL_StatusTypeDef	HAL_UARTEx_EnableFifoMode (UART_HandleTypeDef *huart)
	Enable the FIFO mode.
HAL_StatusTypeDef	HAL_UARTEx_DisableFifoMode (UART_HandleTypeDef *huart)
	Disable the FIFO mode.
HAL_StatusTypeDef	HAL_UARTEx_SetTxFifoThreshold (UART_HandleTypeDef *huart, uint32_t Threshold)
	Set the TXFIFO threshold.
HAL_StatusTypeDef	HAL_UARTEx_SetRxFifoThreshold (UART_HandleTypeDef *huart, uint32_t Threshold)
	Set the RXFIFO threshold.
HAL_StatusTypeDef	HAL_UARTEx_ReceiveToIdle (UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size, uint16_t *RxLen, uint32_t Timeout)
	Receive an amount of data in blocking mode till either the expected number of data is received or an IDLE event occurs.
HAL_StatusTypeDef	HAL_UARTEx_ReceiveToIdle_IT (UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size)
	Receive an amount of data in interrupt mode till either the expected number of data is received or an IDLE event occurs.
HAL_StatusTypeDef	HAL_UARTEx_ReceiveToIdle_DMA (UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size)
	Receive an amount of data in DMA mode till either the expected number of data is received or an IDLE event occurs.

    (#) Declare a UART_HandleTypeDef handle structure.

    (#) For the UART RS485 Driver Enable mode, initialize the UART registers
        by calling the HAL_RS485Ex_Init() API.

    (#) FIFO mode enabling/disabling and RX/TX FIFO threshold programming.

        -@- When UART operates in FIFO mode, FIFO mode must be enabled prior
            starting RX/TX transfers. Also RX/TX FIFO thresholds must be
            configured prior starting RX/TX transfers.
