(USART_TypeDef * USARTx)
Function description
Indicate if One bit sampling method is enabled.
Parameters
USARTx: USART Instance
Return values
State: of bit (1 or 0).

Function name
__STATIC_INLINE void LL_USART_SetBaudRate
(USART_TypeDef * USARTx, uint32_t PeriphClk, uint32_t
OverSampling, uint32_t BaudRate)
Function description
Configure USART BRR register for achieving expected Baud Rate
value.
Parameters
USARTx: USART Instance
PeriphClk: Peripheral Clock
OverSampling: This parameter can be one of the following
values:
LL_USART_OVERSAMPLING_16
LL_USART_OVERSAMPLING_8
BaudRate: Baud Rate
Return values
None:
Notes
Compute and set USARTDIV value in BRR Register (full BRR
content) according to used Peripheral Clock, Oversampling
mode, and expected Baud Rate values
Peripheral clock and Baud rate values provided as function
parameters should be valid (Baud rate value != 0)
