__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.

Parameters

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

Note

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.

Parameters

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

Parameters
