详细描述

函数说明

NVIC_Init()

void NVIC_Init

(

NVIC_InitTypeDef *

NVIC_InitStruct

)

Initializes the NVIC peripheral according to the specified parameters in the NVIC_InitStruct.

参数

NVIC_InitStruct

pointer to a NVIC_InitTypeDef structure that contains the configuration information for the specified NVIC peripheral.

返回值

None

NVIC_PriorityGroupConfig()

void NVIC_PriorityGroupConfig

(

uint32_t

NVIC_PriorityGroup

)

Configures the priority grouping: pre-emption priority and subpriority.

参数

NVIC_PriorityGroup

specifies the priority grouping bits length. This parameter can be one of the following values: NVIC_PriorityGroup_0: 0 bits for pre-emption priority 4 bits for subpriority NVIC_PriorityGroup_1: 1 bits for pre-emption priority 3 bits for subpriority NVIC_PriorityGroup_2: 2 bits for pre-emption priority 2 bits for subpriority NVIC_PriorityGroup_3: 3 bits for pre-emption priority 1 bits for subpriority NVIC_PriorityGroup_4: 4 bits for pre-emption priority 0 bits for subpriority

返回值

None

NVIC_SetVectorTable()

void NVIC_SetVectorTable	(	uint32_t	NVIC_VectTab,
		uint32_t	Offset
	)

Sets the vector table location and Offset.

参数

NVIC_VectTab	specifies if the vector table is in RAM or FLASH memory. This parameter can be one of the following values: NVIC_VectTab_RAM NVIC_VectTab_FLASH
Offset	Vector Table base offset field. This value must be a multiple of 0x200.

返回值

None

NVIC_SystemLPConfig()

void NVIC_SystemLPConfig	(	uint8_t	LowPowerMode,
		FunctionalState	NewState
	)

Selects the condition for the system to enter low power mode.

参数

LowPowerMode	Specifies the new mode for the system to enter low power mode. This parameter can be one of the following values: NVIC_LP_SEVONPEND NVIC_LP_SLEEPDEEP NVIC_LP_SLEEPONEXIT
NewState	new state of LP condition. This parameter can be: ENABLE or DISABLE.

返回值

None

SysTick_CLKSourceConfig()

void SysTick_CLKSourceConfig

(

uint32_t

SysTick_CLKSource

)

Configures the SysTick clock source.

参数

SysTick_CLKSource

specifies the SysTick clock source. This parameter can be one of the following values: SysTick_CLKSource_HCLK_Div8: AHB clock divided by 8 selected as SysTick clock source. SysTick_CLKSource_HCLK: AHB clock selected as SysTick clock source.

返回值

None
