void _unhandled_interrupt

(

void

)

Default interrupt handler.

Note

Taken and adapted from Newlib.

void INTC_register_interrupt	(	__int_handler	handler,
		unsigned int	irq,
		unsigned int	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, what can be done thanks to pure assembly, inline assembly or the `__attribute__((interrupt))' C function attribute.

If several interrupt handlers of a same group are registered, all interrupts of this group will fetch the last interrupt handler registered for this group with the last registered interrupt priority level.
