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
