◆ enable

USART_Enable_TypeDef USART_InitSync_TypeDef::enable

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

uint32_t USART_InitSync_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_InitSync_TypeDef::baudrate

Desired baud rate.

USART_Databits_TypeDef USART_InitSync_TypeDef::databits

Number of data bits in frame.

bool USART_InitSync_TypeDef::master

Select if to operate in master or slave mode.

bool USART_InitSync_TypeDef::msbf

Select if to send most or least significant bit first.

USART_ClockMode_TypeDef USART_InitSync_TypeDef::clockMode

Clock polarity/phase mode.

bool USART_InitSync_TypeDef::autoCsEnable

Auto CS enabling.

bool USART_InitSync_TypeDef::csInv

Enable CS invert.

By default, chip select is active low. Set to true to make chip select active high.
