Field Documentation
◆ enable
| USART_Enable_TypeDef USART_InitSync_TypeDef::enable |
Specifies whether TX and/or RX shall be enabled when initialization is completed.
◆ refFreq
| 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.
◆ baudrate
| uint32_t USART_InitSync_TypeDef::baudrate |
Desired baud rate.
◆ databits
| USART_Databits_TypeDef USART_InitSync_TypeDef::databits |
Number of data bits in frame.
◆ master
| bool USART_InitSync_TypeDef::master |
Select if to operate in master or slave mode.
◆ msbf
| bool USART_InitSync_TypeDef::msbf |
Select if to send most or least significant bit first.
◆ clockMode
| USART_ClockMode_TypeDef USART_InitSync_TypeDef::clockMode |
Clock polarity/phase mode.
◆ prsRxEnable
| bool USART_InitSync_TypeDef::prsRxEnable |
Enable USART Rx via PRS.
◆ prsRxCh
| USART_PRS_Channel_t USART_InitSync_TypeDef::prsRxCh |
Select PRS channel for USART Rx.
(Only valid if prsRxEnable is true).
◆ autoTx
| bool USART_InitSync_TypeDef::autoTx |
Enable AUTOTX mode.
Transmits as long as RX is not full. Generates underflows if TX is empty.
◆ autoCsEnable
| bool USART_InitSync_TypeDef::autoCsEnable |
Auto CS enabling.
◆ autoCsHold
| uint8_t USART_InitSync_TypeDef::autoCsHold |
Auto CS hold time in baud cycles.
◆ autoCsSetup
| uint8_t USART_InitSync_TypeDef::autoCsSetup |
Auto CS setup time in baud cycles.
