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

Examples:

usart_interrupt.c.

Definition at line 136 of file misc.c.

Here is the caller graph for this function:

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

Definition at line 118 of file misc.c.

Here is the caller graph for this function:

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

Definition at line 180 of file misc.c.

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

Definition at line 199 of file misc.c.

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
