Set to 0 to use the currently configured reference clock.


Definition at line 296 of file platform/emlib/inc/em_usart.h

baudrate#

uint32_t USART_InitAsync_TypeDef::baudrate

Desired baud rate.


Definition at line 299 of file platform/emlib/inc/em_usart.h

oversampling#

USART_OVS_TypeDef USART_InitAsync_TypeDef::oversampling

Oversampling used.


Definition at line 302 of file platform/emlib/inc/em_usart.h

databits#

USART_Databits_TypeDef USART_InitAsync_TypeDef::databits

parity#

USART_Parity_TypeDef USART_InitAsync_TypeDef::parity

Parity mode to use.


Definition at line 309 of file platform/emlib/inc/em_usart.h

stopbits#

USART_Stopbits_TypeDef USART_InitAsync_TypeDef::stopbits

Number of stop bits to use.


Definition at line 312 of file platform/emlib/inc/em_usart.h

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.


Definition at line 319 of file platform/emlib/inc/em_usart.h

prsRxCh#

USART_PRS_Channel_t USART_InitAsync_TypeDef::prsRxCh

Select PRS channel for USART Rx.

(Only valid if prsRxEnable is true).


Definition at line 322 of file platform/emlib/inc/em_usart.h
