6.3.3
IRL interrupts are input by level at pins IRL3 to IRL0. The priority level is the higher of those
indicated by pins IRL3 to IRL0. An IRL3 to 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). Figure 6.2 shows an examples of an IRL interrupt connection. Table
6.2 shows IRL pins and interrupt levels.
