uint32_t EUSART_BaudrateGet ( EUSART_TypeDef * eusart )

Gets the current baudrate.

Definition at line 418 of file em_eusart.c .

References CMU_ClockFreqGet() .

void EUSART_BaudrateSet	(	EUSART_TypeDef *	`eusart,`
		uint32_t	`refFreq,`
		uint32_t	`baudrate`
	)

Configures the baudrate (or as close as possible to a specified baudrate).

Note: (1) When the oversampling is disabled, the peripheral clock frequency must be at least three times higher than the chosen baud rate.

void EUSART_IrDAInit	(	EUSART_TypeDef *	`eusart,`
		const EUSART_IrDAInit_TypeDef *	`irdaInit`

void EUSART_Reset ( EUSART_TypeDef * eusart )

Configure the EUSART to its reset state.

uint8_t EUSART_Rx ( EUSART_TypeDef * eusart )

Receives one 8 bit frame, (or part of 9 bit frame).

Definition at line 261 of file em_eusart.c .

void EUSART_RxBlock	(	EUSART_TypeDef *	`eusart,`
		`EUSART_BlockRx_TypeDef`	`enable`
	)

Enable/Disable reception operations until the configured start frame is received.

uint16_t EUSART_RxExt ( EUSART_TypeDef * eusart )

Receives one 8-9 bit frame with extended information.

Definition at line 271 of file em_eusart.c .

void EUSART_Tx	(	EUSART_TypeDef *	`eusart,`
		uint8_t	`data`
	)

Transmits one frame.

void EUSART_TxTristateSet	(	EUSART_TypeDef *	`eusart,`
		`EUSART_TristateTx_TypeDef`	`enable`

void EUSART_UartInitHf	(	EUSART_TypeDef *	`eusart,`
		const EUSART_UartInit_TypeDef *	`init`
	)

Initializes the EUSART when used with the high frequency clock.

void EUSART_UartInitLf	(	EUSART_TypeDef *	`eusart,`
		const EUSART_UartInit_TypeDef *	`init`
	)

Initializes the EUSART when used with the low frequency clock.

Note: (1) When EUSART oversampling is set to eusartOVS0 (Disable), the peripheral clock frequency must be at least three times higher than the chosen baud rate. In LF, max input clock is 32768 (LFXO or LFRCO), thus 32768 / 3 ~ 9600 baudrate.
