Detailed Description

Function Documentation

DDL_USART_ClockInit()

ErrorStatus DDL_USART_ClockInit	(	USART_TypeDef *	USARTx,
		DDL_USART_ClockInitTypeDef *	USART_ClockInitStruct )

Initialize USART Clock related settings according to the specified parameters in the USART_ClockInitStruct.

Note

As some bits in USART configuration registers can only be written when the USART is disabled (USART_CTRL1_UEN bit =0), USART IP should be in disabled state prior calling this function. Otherwise, ERROR result will be returned.

Parameters

USARTx	USART Instance
USART_ClockInitStruct	Pointer to a DDL_USART_ClockInitTypeDef structure that contains the Clock configuration information for the specified USART peripheral.

Return values

An	ErrorStatus enumeration value: SUCCESS: USART registers related to Clock settings are initialized according to USART_ClockInitStruct content ERROR: Problem occurred during USART Registers initialization

DDL_USART_ClockStructInit()

void DDL_USART_ClockStructInit

(

DDL_USART_ClockInitTypeDef *

USART_ClockInitStruct

)

Set each field of a DDL_USART_ClockInitTypeDef type structure to default value.

Parameters

USART_ClockInitStruct

Pointer to a DDL_USART_ClockInitTypeDef structure whose fields will be set to default values.

Return values

None

Definition at line 358 of file g32r4xx_ddl_usart.c.

DDL_USART_DeInit()

ErrorStatus DDL_USART_DeInit

(

USART_TypeDef *

USARTx

)

De-initialize USART registers (Registers restored to their default values).

Parameters

USARTx

USART Instance

Return values

An	ErrorStatus enumeration value: SUCCESS: USART registers are de-initialized ERROR: USART registers are not de-initialized

Definition at line 148 of file g32r4xx_ddl_usart.c.

DDL_USART_Init()

ErrorStatus DDL_USART_Init	(	USART_TypeDef *	USARTx,
		DDL_USART_InitTypeDef *	USART_InitStruct )

Initialize USART registers according to the specified parameters in USART_InitStruct.

Note

As some bits in USART configuration registers can only be written when the USART is disabled (USART_CTRL1_UEN bit =0), USART IP should be in disabled state prior calling this function. Otherwise, ERROR result will be returned.

Baud rate value stored in USART_InitStruct BaudRate field, should be valid (different from 0).

Parameters

USARTx	USART Instance
USART_InitStruct	pointer to a DDL_USART_InitTypeDef structure that contains the configuration information for the specified USART peripheral.

Return values

An	ErrorStatus enumeration value: SUCCESS: USART registers are initialized according to USART_InitStruct content ERROR: Problem occurred during USART Registers initialization

Definition at line 194 of file g32r4xx_ddl_usart.c.

DDL_USART_StructInit()

void DDL_USART_StructInit

(

DDL_USART_InitTypeDef *

USART_InitStruct

)

Set each DDL_USART_InitTypeDef field to default value.

Parameters

USART_InitStruct

Pointer to a DDL_USART_InitTypeDef structure whose fields will be set to default values.

Return values

None
