LL_USART_ConfigSyncMode
Function name
__STATIC_INLINE void LL_USART_ConfigSyncMode
(USART_TypeDef * USARTx)
Function description
Perform basic configuration of USART for enabling use in
Synchronous Mode.
Parameters
USARTx: USART Instance
Return values
None:
Notes
In Synchronous mode, the following bits must be kept
cleared: LINEN 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. This function
also sets the USART in Synchronous mode.
Macro IS_USART_INSTANCE(USARTx) can be used to
check whether or not Synchronous mode is supported by the
USARTx instance.
Call of this function is equivalent to following function call
sequence : Clear LINEN in CR2 using
LL_USART_DisableLIN() functionClear IREN in CR3 using
LL_USART_DisableIrda() functionClear SCEN in CR3 using
LL_USART_DisableSmartcard() functionClear HDSEL in CR3
using LL_USART_DisableHalfDuplex() functionSet CLKEN in
CR2 using LL_USART_EnableSCLKOutput() function
Other remaining configurations items related to Synchronous
Mode (as Baud Rate, Word length, Parity, Clock Polarity, ...)
should be set using dedicated functions

Function name
__STATIC_INLINE void LL_USART_ConfigLINMode
(USART_TypeDef * USARTx)
Function description
Perform basic configuration of USART for enabling use in LIN
Mode.
Parameters
USARTx: USART Instance
Return values
None:
Notes
In LIN mode, the following bits must be kept cleared: STOP
and CLKEN bits 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. This function
also set the UART/USART in LIN mode.
Macro IS_UART_LIN_INSTANCE(USARTx) can be used to
check whether or not LIN feature is supported by the USARTx
instance.
Call of this function is equivalent to following function call
sequence : Clear CLKEN in CR2 using
