Interrupt controller
L6460 contains one programmable interrupt controller that can be used to advice the
firmware, through the serial interface, when a certain event happens inside the IC. The
output of the interrupt circuit can be also redirected on a GPIO pin therefore the event can
be signaled directly to the external circuits.
