__STATIC_INLINE void LL_LPUART_ConfigNodeAddress	(	USART_TypeDef *	LPUARTx,
		uint32_t	AddressLen,
		uint32_t	NodeAddress
	)

Set Address of the LPUART node.

Note:: This is used in multiprocessor communication during Mute mode or Stop mode, for wake up with address mark detection.; 4bits address node is used when 4-bit Address Detection is selected in ADDM7. (b7-b4 should be set to 0) 8bits address node is used when 7-bit Address Detection is selected in ADDM7. (This is used in multiprocessor communication during Mute mode or Stop mode, for wake up with 7-bit address mark detection. The MSB of the character sent by the transmitter should be equal to 1. It may also be used for character detection during normal reception, Mute mode inactive (for example, end of block detection in ModBus protocol). In this case, the whole received character (8-bit) is compared to the ADD[7:0] value and CMF flag is set on match)

__STATIC_INLINE void LL_LPUART_Disable ( USART_TypeDef * LPUARTx )

LPUART Disable.

Note:: When LPUART is disabled, LPUART prescalers and outputs are stopped immediately, and current operations are discarded. The configuration of the LPUART is kept, but all the status flags, in the LPUARTx_ISR are set to their default values.; In order to go into low-power mode without generating errors on the line, the TE bit must be reset before and the software must wait for the TC bit in the LPUART_ISR to be set before resetting the UE bit. The DMA requests are also reset when UE = 0 so the DMA channel must be disabled before resetting the UE bit.

__STATIC_INLINE void LL_LPUART_SetBaudRate	(	USART_TypeDef *	LPUARTx,
		uint32_t	PeriphClk,
		uint32_t	BaudRate
	)

Configure LPUART BRR register for achieving expected Baud Rate value.

Note:: Compute and set LPUARTDIV value in BRR Register (full BRR content) according to used Peripheral Clock and expected Baud Rate values; Peripheral clock and Baud Rate values provided as function parameters should be valid (Baud rate value != 0).; Provided that LPUARTx_BRR must be > = 0x300 and LPUART_BRR is 20-bit, a care should be taken when generating high baud rates using high PeriphClk values. PeriphClk must be in the range [3 x BaudRate, 4096 x BaudRate].
