IRL Interrupts

IRL interrupts are input by level at pins IRL3–IRL0. The priority level is the level indicated by
pins IRL3–IRL0. An IRL3–IRL0 value of 0 (0000) indicates the highest-level interrupt request
(interrupt priority level 15). A value of 15 (1111) indicates no interrupt request (interrupt priority
level 0).
