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
