Set to 0 to use the currently configured reference clock.


Definition at line 439 of file platform/emlib/inc/em_usart.h

baudrate#

uint32_t USART_InitSync_TypeDef::baudrate

Desired baud rate.


Definition at line 442 of file platform/emlib/inc/em_usart.h

databits#

USART_Databits_TypeDef USART_InitSync_TypeDef::databits

Number of data bits in frame.


Definition at line 445 of file platform/emlib/inc/em_usart.h

master#

bool USART_InitSync_TypeDef::master

Select if to operate in master or slave mode.


Definition at line 448 of file platform/emlib/inc/em_usart.h

msbf#

bool USART_InitSync_TypeDef::msbf

Select if to send most or least significant bit first.


Definition at line 451 of file platform/emlib/inc/em_usart.h

clockMode#

USART_ClockMode_TypeDef USART_InitSync_TypeDef::clockMode

Clock polarity/phase mode.


Definition at line 454 of file platform/emlib/inc/em_usart.h

prsRxEnable#

bool USART_InitSync_TypeDef::prsRxEnable

Enable USART Rx via PRS.


Definition at line 458 of file platform/emlib/inc/em_usart.h

prsRxCh#

USART_PRS_Channel_t USART_InitSync_TypeDef::prsRxCh

Select PRS channel for USART Rx.

(Only valid if prsRxEnable is true).


Definition at line 461 of file platform/emlib/inc/em_usart.h

autoTx#

bool USART_InitSync_TypeDef::autoTx

Enable AUTOTX mode.

Transmits as long as RX is not full. Generates underflows if TX is empty.


Definition at line 467 of file platform/emlib/inc/em_usart.h

autoCsEnable#

bool USART_InitSync_TypeDef::autoCsEnable

Auto CS enabling.


Definition at line 471 of file platform/emlib/inc/em_usart.h

csInv#

bool USART_InitSync_TypeDef::csInv

Enable CS invert.

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

autoCsHold#

uint8_t USART_InitSync_TypeDef::autoCsHold

Auto CS hold time in baud cycles.


Definition at line 479 of file platform/emlib/inc/em_usart.h

autoCsSetup#

uint8_t USART_InitSync_TypeDef::autoCsSetup

Auto CS setup time in baud cycles.
