Public Attribute Documentation#

enable#

USART_Enable_TypeDef USART_InitAsync_TypeDef::enable

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


refFreq#

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.


baudrate#

uint32_t USART_InitAsync_TypeDef::baudrate

Desired baud rate.


oversampling#

USART_OVS_TypeDef USART_InitAsync_TypeDef::oversampling

Oversampling used.


databits#

USART_Databits_TypeDef USART_InitAsync_TypeDef::databits

Number of data bits in frame.

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


parity#

USART_Parity_TypeDef USART_InitAsync_TypeDef::parity

Parity mode to use.


stopbits#

USART_Stopbits_TypeDef USART_InitAsync_TypeDef::stopbits

Number of stop bits to use.


mvdis#

bool USART_InitAsync_TypeDef::mvdis

Majority Vote Disable for 16x, 8x and 6x oversampling modes.


prsRxEnable#

bool USART_InitAsync_TypeDef::prsRxEnable

Enable USART Rx via PRS.


prsRxCh#

USART_PRS_Channel_t USART_InitAsync_TypeDef::prsRxCh

Select PRS channel for USART Rx.

(Only valid if prsRxEnable is true).


autoCsEnable#

bool USART_InitAsync_TypeDef::autoCsEnable

Auto CS enabling.


csInv#

bool USART_InitAsync_TypeDef::csInv

Enable CS invert.

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