Set Address of the USART node.

Note: This is used in multiprocessor communication during Mute mode or Stop mode, for wake up with address mark detection.

Parameters

USARTx	USART Instance
NodeAddress	4 bit Address of the USART node.

Return values

None

◆ DDL_USART_SetOverSampling()

__STATIC_INLINE void DDL_USART_SetOverSampling	(	USART_TypeDef *	USARTx,
		uint32_t	OverSampling )

Set Oversampling to 8-bit or 16-bit mode.

Parameters

USARTx	USART Instance
OverSampling	This parameter can be one of the following values: DDL_USART_OVERSAMPLING_16 DDL_USART_OVERSAMPLING_8

Return values

None

Definition at line 628 of file g32r4xx_ddl_usart.h.

◆ DDL_USART_SetParity()

__STATIC_INLINE void DDL_USART_SetParity	(	USART_TypeDef *	USARTx,
		uint32_t	Parity )

Configure Parity (enabled/disabled and parity mode if enabled).

Note: This function selects if hardware parity control (generation and detection) is enabled or disabled. When the parity control is enabled (Odd or Even), computed parity bit is inserted at the MSB position (9th or 8th bit depending on data width) and parity is checked on the received data.

Parameters

USARTx	USART Instance
Parity	This parameter can be one of the following values: DDL_USART_PARITY_NONE DDL_USART_PARITY_EVEN DDL_USART_PARITY_ODD

Return values

None

Definition at line 552 of file g32r4xx_ddl_usart.h.

◆ DDL_USART_SetSampleMethod()

__STATIC_INLINE void DDL_USART_SetSampleMethod	(	USART_TypeDef *	USARTx,
		uint32_t	Sample )

Configure sampling method.

Parameters

USARTx	USART Instance
Sample	Peripheral Clock DDL_USART_SAMPLING_SINGLE DDL_USART_SAMPLING_TRIPLE

Return values

None

Definition at line 1128 of file g32r4xx_ddl_usart.h.

◆ DDL_USART_SetStopBitsLength()

__STATIC_INLINE void DDL_USART_SetStopBitsLength	(	USART_TypeDef *	USARTx,
		uint32_t	StopBits )

Set the length of the stop bits.

Parameters

USARTx	USART Instance
StopBits	This parameter can be one of the following values: DDL_USART_STOPBITS_0_5 DDL_USART_STOPBITS_1 DDL_USART_STOPBITS_1_5 DDL_USART_STOPBITS_2

Return values

None

Definition at line 804 of file g32r4xx_ddl_usart.h.

◆ DDL_USART_SetTransferDirection()

__STATIC_INLINE void DDL_USART_SetTransferDirection	(	USART_TypeDef *	USARTx,
		uint32_t	TransferDirection )

Configure simultaneously enabled/disabled states of Transmitter and Receiver.

Parameters

USARTx	USART Instance
TransferDirection	This parameter can be one of the following values: DDL_USART_DIRECTION_NONE DDL_USART_DIRECTION_RX DDL_USART_DIRECTION_TX DDL_USART_DIRECTION_TX_RX

Return values

None

Definition at line 521 of file g32r4xx_ddl_usart.h.

◆ DDL_USART_SetWakeUpMethod()

__STATIC_INLINE void DDL_USART_SetWakeUpMethod	(	USART_TypeDef *	USARTx,
		uint32_t	Method )

Set Receiver Wake Up method from Mute mode.

Parameters

USARTx	USART Instance
Method	This parameter can be one of the following values: DDL_USART_WAKEUP_IDLELINE DDL_USART_WAKEUP_ADDRESSMARK

Return values

None

Definition at line 578 of file g32r4xx_ddl_usart.h.
