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 1. 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
