4.2 Interrupt Vector Table
Table 4-2 provides the 56F8013/56F8011’s 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. As indicated, the priority of an interrupt can be assigned to different levels, 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.
The location of the vector table is determined by the Vector Base Address (VBA). Please see Section
5.5.11 for the reset value of the VBA.
By default, VBA = 0, and the reset address and COP reset address will correspond to vector 0 and 1 of the
interrupt vector table. In these instances, the first two locations in the vector table must contain branch or
JMP instructions. All other entries must contain JSR instructions.
