13.3.2.2 Interrupt Vector Locations

The interrupt vector placement is dependent on the value of the Interrupt Vector Select (IVSEL) bit in the Control A (CPUINT.CTRLA) register. Refer to the IVSEL description in CPUINT.CTRLA for the possible locations.

If the program never enables an interrupt source, the interrupt vectors are not used, and the regular program code can be placed at these locations.
