◆ enable

USART_Enable_TypeDef USART_InitAsync_TypeDef::enable

Specifies whether TX and/or RX is enabled when initialization is completed.

uint32_t USART_InitAsync_TypeDef::refFreq

USART/UART reference clock assumed when configuring baud rate setup.

Set to 0 to use the currently configured reference clock.

uint32_t USART_InitAsync_TypeDef::baudrate

Desired baud rate.

USART_OVS_TypeDef USART_InitAsync_TypeDef::oversampling

Oversampling used.

USART_Databits_TypeDef USART_InitAsync_TypeDef::databits

Number of data bits in frame.

Notice that UART modules only support 8 or 9 data bits.

USART_Parity_TypeDef USART_InitAsync_TypeDef::parity

Parity mode to use.

USART_Stopbits_TypeDef USART_InitAsync_TypeDef::stopbits

Number of stop bits to use.

bool USART_InitAsync_TypeDef::autoCsEnable

Auto CS enabling.
