void INTC_register_interrupt ( __int_handler  handler,
unsigned int  irq,
unsigned int  int_level 
)

Registers an interrupt handler.

Parameters
handlerInterrupt handler to register.
irqIRQ of the interrupt handler to register.
int_levelInterrupt 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.
