15.2 Reset and Interrupt Vector Placement
8266A-MCU Wireless-12/09
Note:
Table 15-2 below
combinations of BOOTRST and IVSEL settings. If the program never enables an
interrupt source, the Interrupt Vectors are not used, and regular program code can be
placed at these locations. This is also the case if the Reset Vector is in the Application
section while the Interrupt Vectors are in the Boot section or vice versa.
Table 15-2. Reset and Interrupt Vectors Placement
Note:
The most typical and general program setup for the Reset and Interrupt Vector
Addresses in ATmega128RFA1 is:

1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader
2. When the IVSEL bit in MCUCR is set, Interrupt Vectors will be moved to the start
3. Not usefull in ATmega128RFA1 due to limited pin count.
