Functions
void	avr_interrupt_init (avr_t *avr)
	Initializes the interrupt table. More...
void	avr_interrupt_reset (avr_t *avr)
	Reset the interrupt table and the fifo. More...
void	avr_register_vector (avr_t *avr, avr_int_vector_t *vector)
	Register an interrupt vector. It's only needed if you want to use the "r_raised" flags. More...
int	avr_has_pending_interrupts (avr_t *avr)
	Return non-zero if the AVR core has any pending interrupts. More...
int	avr_is_interrupt_pending (avr_t *avr, avr_int_vector_t *vector)
	Return nonzero if a specific interrupt vector is pending. More...
int	avr_is_interrupt_enabled (avr_t *avr, avr_int_vector_t *vector)
int	avr_raise_interrupt (avr_t *avr, avr_int_vector_t *vector)
	Raise an interrupt (if enabled). More...
void	avr_clear_interrupt (avr_t *avr, avr_int_vector_t *vector)
	Clear the "pending" status of an interrupt. More...
int	avr_clear_interrupt_if (avr_t *avr, avr_int_vector_t *vector, uint8_t old)
	Clear the interrupt (inc pending) if "raised" flag is 1. More...
avr_irq_t *	avr_get_interrupt_irq (avr_t *avr, uint8_t v)
	Return the IRQ that is raised when the vector is enabled and called/cleared this allows tracing of pending interrupts. More...
void	avr_service_interrupts (avr_t *avr)
	Called by the core at each cycle to check whether an interrupt is pending. More...
