Function Documentation

intc_enable_irq()

__STATIC_INLINE void intc_enable_irq

(

IRQn_Type

IRQn

)

Enable Interrupt.

Enables a device specific interrupt in the NVIC interrupt controller.

Parameters

[in]

IRQn

Device specific interrupt number.

Note

IRQn must not be negative.

intc_is_irq_enabled()

__STATIC_INLINE bool intc_is_irq_enabled

(

IRQn_Type

IRQn

)

Get Interrupt Enable status.

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

Parameters

[in]

IRQn

Device specific interrupt number.

Returns

0 Interrupt is not enabled.

1 Interrupt is enabled.

Note

IRQn must not be negative.

intc_disable_irq()

__arm void intc_disable_irq ( IRQn_Type  IRQn )

extern

Disable Interrupt.

Disables a device specific interrupt in the NVIC interrupt controller.

Parameters

[in]

IRQn

Device specific interrupt number.

Note

IRQn must not be negative.

intc_is_irq_pending()

__STATIC_INLINE bool intc_is_irq_pending

(

IRQn_Type

IRQn

)

Get Pending Interrupt.

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

Parameters

[in]

IRQn

Device specific interrupt number.

Returns

0 Interrupt status is not pending.

1 Interrupt status is pending.

Note

IRQn must not be negative.

intc_pending_set()

__STATIC_INLINE void intc_pending_set

(

IRQn_Type

IRQn

)

Set Pending Interrupt.

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

Parameters

[in]

IRQn

Device specific interrupt number.

Note

IRQn must not be negative.

intc_pending_clear()

__STATIC_INLINE void intc_pending_clear

(

IRQn_Type

IRQn

)

Clear Pending Interrupt.

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

Parameters

[in]

IRQn

Device specific interrupt number.

Note

IRQn must not be negative.

intc_get_active_irq()

__STATIC_INLINE uint32_t intc_get_active_irq

(

void

)

intc_priority_set()

__STATIC_INLINE void intc_priority_set	(	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.

intc_priority_get()

__STATIC_INLINE uint32_t intc_priority_get

(

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]

IRQn

Interrupt number.

Returns

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

intc_init()

void intc_init ( void  )

extern

set vector table

enable all interrupt source

disable all interrupt

clear all pending bit

Mask interrupts with lower or the same priority
