Function Documentation

void NVIC_Init

(

NVIC_InitTypeDef *

NVIC_InitStruct

)

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

Note

To configure interrupts priority correctly, the NVIC_PriorityGroupConfig() function should be called before.

Parameters

NVIC_InitStruct,:

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

Return values

None

void NVIC_PriorityGroupConfig

(

uint32_t

NVIC_PriorityGroup

)

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

Parameters

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

Note

When the NVIC_PriorityGroup_0 is selected, IRQ pre-emption is no more possible. The pending IRQ priority will be managed only by the subpriority.

Return values

None

void NVIC_SetVectorTable	(	uint32_t	NVIC_VectTab,
		uint32_t	Offset
	)

Sets the vector table location and Offset.

Parameters

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: Vector Table in internal SRAM. NVIC_VectTab_FLASH: Vector Table in internal FLASH.
Offset,:	Vector Table base offset field. This value must be a multiple of 0x200.

Return values

None

void NVIC_SystemLPConfig	(	uint8_t	LowPowerMode,
		FunctionalState	NewState
	)

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

Parameters

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: Low Power SEV on Pend. NVIC_LP_SLEEPDEEP: Low Power DEEPSLEEP request. NVIC_LP_SLEEPONEXIT: Low Power Sleep on Exit.
NewState,:	new state of LP condition. This parameter can be: ENABLE or DISABLE.

Return values

None

void SysTick_CLKSourceConfig

(

uint32_t

SysTick_CLKSource

)

Configures the SysTick clock source.

Parameters

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.

Return values

None
