14.3.2.2 Interrupt Vector Locations

The Interrupt vector placement is dependent on the value of Interrupt Vector Select bit (IVSEL) in the Control A register (CPUINT.CTRLA). 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 regular program code can be placed at these locations.
