Function name
__STATIC_INLINE uint32_t LL_USART_IsEnabledLIN
(USART_TypeDef * USARTx)
Function description
Indicate if LIN mode is enabled.
Parameters
USARTx: USART Instance
Return values
State: of bit (1 or 0).
Notes
Macro IS_UART_LIN_INSTANCE(USARTx) can be used to
check whether or not LIN feature is supported by the USARTx
instance.

LL_USART_ConfigAsyncMode
Function name
__STATIC_INLINE void LL_USART_ConfigAsyncMode
(USART_TypeDef * USARTx)
Function description
Perform basic configuration of USART for enabling use in
Asynchronous Mode (UART)
Parameters
USARTx: USART Instance
Return values
None:
Notes
In UART mode, the following bits must be kept cleared:
LINEN bit in the USART_CR2 register,CLKEN bit in the
USART_CR2 register,SCEN bit in the USART_CR3
register,IREN bit in the USART_CR3 register,HDSEL bit in
the USART_CR3 register.
Call of this function is equivalent to following function call
sequence : Clear LINEN in CR2 using
LL_USART_DisableLIN() functionClear CLKEN in CR2 using
LL_USART_DisableSCLKOutput() functionClear SCEN in
CR3 using LL_USART_DisableSmartcard() functionClear
IREN in CR3 using LL_USART_DisableIrda() functionClear
HDSEL in CR3 using LL_USART_DisableHalfDuplex()
function
Other remaining configurations items related to Asynchronous
Mode (as Baud Rate, Word length, Parity, ...) should be set
using dedicated functions
