#define AVR32_INTC_MAX_NUM_IRQS_PER_GRP   32

Maximal number of interrupt request lines per group.

Referenced by INTC_register_interrupt().

#define AVR32_INTC_NUM_INT_LEVELS   (1 << AVR32_INTC_IPR_INTLEVEL_SIZE)

Number of interrupt priority levels.

void INTC_init_interrupts

(

void

)

Initializes the hardware interrupt controller driver.

void INTC_register_interrupt	(	__int_handler	handler,
		uint32_t	irq,
		uint32_t	int_level
	)

Registers an interrupt handler.

Parameters

handler	Interrupt handler to register.
irq	IRQ of the interrupt handler to register.
int_level	Interrupt priority level to assign to the group of this IRQ.

Warning

The interrupt handler must manage the `rete' instruction, which can be done using pure assembly, inline assembly or the `__attribute__((interrupt))' C function attribute.

If several interrupt handlers of a same group are registered with different priority levels, only the latest priority level set will be effective.
