Function Documentation

§ __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.

Parameters
[in]PriorityGroupPriority grouping field.

References SCB, SCB_AIRCR_PRIGROUP_Msk, SCB_AIRCR_PRIGROUP_Pos, SCB_AIRCR_VECTKEY_Msk, and SCB_AIRCR_VECTKEY_Pos.

§ __NVIC_GetPriorityGrouping()

__STATIC_INLINE uint32_t __NVIC_GetPriorityGrouping ( void  )

Get Priority Grouping.

Reads the priority grouping field from the NVIC Interrupt Controller.

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

References SCB, SCB_AIRCR_PRIGROUP_Msk, and SCB_AIRCR_PRIGROUP_Pos.

§ __NVIC_EnableIRQ()

__STATIC_INLINE void __NVIC_EnableIRQ ( IRQn_Type  IRQn)

Enable Interrupt.

Enables a device specific interrupt in the NVIC interrupt controller.

Parameters
[in]IRQnDevice specific interrupt number.
Note
IRQn must not be negative.

References __COMPILER_BARRIER, and NVIC.

§ __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.

§ __NVIC_SetPriority()

__STATIC_INLINE void __NVIC_SetPriority ( IRQn_Type  IRQn,
uint32_t  priority

Parameters
[in]IRQnInterrupt number.
[in]priorityPriority to set.
Note

§ __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.

Parameters
[in]IRQnInterrupt number.
Returns
Interrupt Priority. Value is aligned automatically to the implemented priority bits of the microcontroller.

§ 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.

Parameters
[in]PriorityGroupUsed priority group.
[in]PreemptPriorityPreemptive priority value (starting from 0).
[in]SubPrioritySubpriority value (starting from 0).
Returns
Encoded priority. Value can be used in the function NVIC_SetPriority().

§ 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.

Parameters
[in]PriorityPriority value, which can be retrieved with the function NVIC_GetPriority().
[in]PriorityGroupUsed priority group.
[out]pPreemptPriorityPreemptive priority value (starting from 0).
[out]pSubPrioritySubpriority value (starting from 0).

§ __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.

Parameters
[in]IRQnInterrupt number
[in]vectorAddress of interrupt handler function

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. If VTOR is not present address 0 must be mapped to SRAM.

Parameters
[in]IRQnInterrupt number
[in]vectorAddress of interrupt handler function
