Functions that manage interrupts and exceptions via the NVIC.

函数说明

◆ __NVIC_ClearPendingIRQ()

__STATIC_INLINE void __NVIC_ClearPendingIRQ ( IRQn_Type IRQn )

Clear Pending Interrupt

Clears the pending bit of a device specific interrupt in the NVIC pending register.

参数

[in] IRQn Device specific interrupt number.

注解: IRQn must not be negative.

◆ __NVIC_DisableIRQ()

__STATIC_INLINE void __NVIC_DisableIRQ ( IRQn_Type IRQn )

Disable Interrupt

Disables a device specific interrupt in the NVIC interrupt controller.

参数

[in] IRQn Device specific interrupt number.

注解: IRQn must not be negative.

◆ __NVIC_EnableIRQ()

__STATIC_INLINE void __NVIC_EnableIRQ ( IRQn_Type IRQn )

Enable Interrupt

Enables a device specific interrupt in the NVIC interrupt controller.

参数

[in] IRQn Device specific interrupt number.

注解: IRQn must not be negative.

◆ __NVIC_GetActive()

__STATIC_INLINE uint32_t __NVIC_GetActive ( IRQn_Type IRQn )

Get Active Interrupt

Reads the active register in the NVIC and returns the active bit for the device specific interrupt.

参数

[in] IRQn Device specific interrupt number.

返回: 0 Interrupt status is not active.; 1 Interrupt status is active.

注解: IRQn must not be negative.

◆ __NVIC_GetEnableIRQ()

__STATIC_INLINE uint32_t __NVIC_GetEnableIRQ ( IRQn_Type IRQn )

Get Interrupt Enable status

Returns a device specific interrupt enable status from the NVIC interrupt controller.

参数

[in] IRQn Device specific interrupt number.

返回: 0 Interrupt is not enabled.; 1 Interrupt is enabled.

注解: IRQn must not be negative.

◆ __NVIC_GetPendingIRQ()

__STATIC_INLINE uint32_t __NVIC_GetPendingIRQ ( IRQn_Type IRQn )

Get Pending Interrupt

Reads the NVIC pending register and returns the pending bit for the specified device specific interrupt.

参数

[in] IRQn Device specific interrupt number.

返回: 0 Interrupt status is not pending.; 1 Interrupt status is pending.

注解: IRQn must not be negative.

◆ __NVIC_GetPriority()

__STATIC_INLINE uint32_t __NVIC_GetPriority ( IRQn_Type IRQn )

Get Interrupt Priority

Reads the priority of a device specific interrupt or a processor exception. The interrupt number can be positive to specify a device specific interrupt, or negative to specify a processor exception.

参数

[in] IRQn Interrupt number.

返回: Interrupt Priority. Value is aligned automatically to the implemented priority bits of the microcontroller.

◆ __NVIC_GetPriorityGrouping()

__STATIC_INLINE uint32_t __NVIC_GetPriorityGrouping ( void )

Get Priority Grouping

Reads the priority grouping field from the NVIC Interrupt Controller.

返回: Priority grouping field (SCB->AIRCR [10:8] PRIGROUP field).

◆ __NVIC_GetVector()

__STATIC_INLINE uint32_t __NVIC_GetVector ( IRQn_Type IRQn )

Get Interrupt Vector

Reads an interrupt vector from interrupt vector table. The interrupt number can be positive to specify a device specific interrupt, or negative to specify a processor exception.

参数

[in] IRQn Interrupt number.

返回: Address of interrupt handler function

◆ __NVIC_SetPendingIRQ()

__STATIC_INLINE void __NVIC_SetPendingIRQ ( IRQn_Type IRQn )

Set Pending Interrupt

Sets the pending bit of a device specific interrupt in the NVIC pending register.

参数

[in] IRQn Device specific interrupt number.

注解: IRQn must not be negative.

◆ __NVIC_SetPriority()

__STATIC_INLINE void __NVIC_SetPriority	(	IRQn_Type	IRQn,
		uint32_t	priority
	)

Set Interrupt Priority

Sets the priority of a device specific interrupt or a processor exception. The interrupt number can be positive to specify a device specific interrupt, or negative to specify a processor exception.

参数

[in]	IRQn	Interrupt number.
[in]	priority	Priority to set.

注解: The priority cannot be set for every processor exception.

◆ __NVIC_SetPriorityGrouping()

__STATIC_INLINE void __NVIC_SetPriorityGrouping ( uint32_t PriorityGroup )

Set Priority Grouping

Sets the priority grouping field using the required unlock sequence. The parameter PriorityGroup is assigned to the field SCB->AIRCR [10:8] PRIGROUP field. Only values from 0..7 are used. In case of a conflict between priority grouping and available priority bits (__NVIC_PRIO_BITS), the smallest possible priority group is set.

参数

[in] PriorityGroup Priority grouping field.

◆ __NVIC_SetVector()

__STATIC_INLINE void __NVIC_SetVector	(	IRQn_Type	IRQn,
		uint32_t	vector
	)

Set Interrupt Vector

Sets an interrupt vector in SRAM based interrupt vector table. The interrupt number can be positive to specify a device specific interrupt, or negative to specify a processor exception. VTOR must been relocated to SRAM before.

参数

[in]	IRQn	Interrupt number
[in]	vector	Address of interrupt handler function

◆ __NVIC_SystemReset()

__NO_RETURN __STATIC_INLINE void __NVIC_SystemReset ( void )

System Reset

Initiates a system reset request to reset the MCU.

◆ NVIC_DecodePriority()

__STATIC_INLINE void NVIC_DecodePriority	(	uint32_t	Priority,
		uint32_t	PriorityGroup,
		uint32_t *const	pPreemptPriority,
		uint32_t *const	pSubPriority
	)

Decode Priority

Decodes an interrupt priority value with a given priority group to preemptive priority value and subpriority value. In case of a conflict between priority grouping and available priority bits (__NVIC_PRIO_BITS) the smallest possible priority group is set.

参数

[in]	Priority	Priority value, which can be retrieved with the function NVIC_GetPriority().
[in]	PriorityGroup	Used priority group.
[out]	pPreemptPriority	Preemptive priority value (starting from 0).
[out]	pSubPriority	Subpriority value (starting from 0).

◆ NVIC_EncodePriority()

__STATIC_INLINE uint32_t NVIC_EncodePriority	(	uint32_t	PriorityGroup,
		uint32_t	PreemptPriority,
		uint32_t	SubPriority
	)

Encode Priority

Encodes the priority for an interrupt with the given priority group, preemptive priority value, and subpriority value. In case of a conflict between priority grouping and available priority bits (__NVIC_PRIO_BITS), the smallest possible priority group is set.

参数

[in]	PriorityGroup	Used priority group.
[in]	PreemptPriority	Preemptive priority value (starting from 0).
[in]	SubPriority	Subpriority value (starting from 0).

返回: Encoded priority. Value can be used in the function NVIC_SetPriority().
