uint32_t LL_USART_InitTypeDef::BaudRate
This field defines expected Usart communication baud rate.This feature can be
modified afterwards using unitary function LL_USART_SetBaudRate().
uint32_t LL_USART_InitTypeDef::DataWidth
Specifies the number of data bits transmitted or received in a frame. This parameter
can be a value of USART_LL_EC_DATAWIDTH.This feature can be modified
afterwards using unitary function LL_USART_SetDataWidth().
uint32_t LL_USART_InitTypeDef::StopBits
Specifies the number of stop bits transmitted. This parameter can be a value of
USART_LL_EC_STOPBITS.This feature can be modified afterwards using unitary
function LL_USART_SetStopBitsLength().
uint32_t LL_USART_InitTypeDef::Parity
Specifies the parity mode. This parameter can be a value of
USART_LL_EC_PARITY.This feature can be modified afterwards using unitary
function LL_USART_SetParity().
uint32_t LL_USART_InitTypeDef::TransferDirection
Specifies whether the Receive and/or Transmit mode is enabled or disabled. This
parameter can be a value of USART_LL_EC_DIRECTION.This feature can be
modified afterwards using unitary function LL_USART_SetTransferDirection().
uint32_t LL_USART_InitTypeDef::HardwareFlowControl
Specifies whether the hardware flow control mode is enabled or disabled. This
parameter can be a value of USART_LL_EC_HWCONTROL.This feature can be
modified afterwards using unitary function LL_USART_SetHWFlowCtrl().
uint32_t LL_USART_InitTypeDef::OverSampling
Specifies whether USART oversampling mode is 16 or 8. This parameter can be a
value of USART_LL_EC_OVERSAMPLING.This feature can be modified afterwards
using unitary function LL_USART_SetOverSampling().
