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) register. Please see
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: PWMA, FlexCAN, Quadrature Decoder 1, and Quad Timers B and D are NOT available on the
56F8135 device.
