Data Structures
struct	UART_WakeUpTypeDef
	UART wake up from stop mode parameters. More...
Defines
#define	UART_WORDLENGTH_7B   USART_CR1_M1
#define	UART_WORDLENGTH_8B   0x00000000U
#define	UART_WORDLENGTH_9B   USART_CR1_M0
#define	UART_ADDRESS_DETECT_4B   0x00000000U
#define	UART_ADDRESS_DETECT_7B   USART_CR2_ADDM7
#define	UART_GETCLOCKSOURCE(__HANDLE__, __CLOCKSOURCE__)
	Report the UART clock source.
#define	UART_MASK_COMPUTATION(__HANDLE__)
	Report the UART mask to apply to retrieve the received data according to the word length and to the parity bits activation.
#define	IS_UART_WORD_LENGTH(__LENGTH__)
	Ensure that UART frame length is valid.
#define	IS_UART_ADDRESSLENGTH_DETECT(__ADDRESS__)
	Ensure that UART wake-up address length is valid.
Functions
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.
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_EnableClockStopMode (UART_HandleTypeDef *huart)
	Keep UART Clock enabled when in Stop Mode.
HAL_StatusTypeDef	HAL_UARTEx_DisableClockStopMode (UART_HandleTypeDef *huart)
	Disable UART Clock when in Stop Mode.
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).
