13.3.2.2 Interrupt Vector Locations

The table below shows Reset addresses and Interrupt vector placement, dependent on the value of Interrupt Vector Select bit (IVSEL) in the Control A register (CPUINT.CTRLA).

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

Table 13-2. Reset and Interrupt Vector Placement
IVSEL	Reset address	Interrupt vectors start address
0	0x0000	Application start address + Interrupt vector offset address
1	0x0000	Interrupt vector offset address
