4.3 Interrupt Vector Table
Table 4-3
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 5.6.11
In some configurations, 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.
Note: PWM, CAN and Quadrature Decoder are NOT available on the 56F8122 device.
