Preliminary
4.3 Interrupt Vector Table
Table 4-5 provides the reset and interrupt priority structure, including on-chip peripherals. The table is
organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. The
priority of an interrupt can be assigned to different levels, as indicated, allowing some control over
interrupt priorities. All level 3 interrupts will be serviced before level 2, and so on. For a selected priority
level, the lowest vector number has the highest priority.
