Register Description
Moving Interrupts Between Application and Boot Space, ATmega88A/88PA, ATmega168A/168PA and
ATmega328/328P
When the BOOTRST Fuse is programmed, the Boot section size set to 2K bytes and the IVSEL
bit in the MCUCR Register is set before any interrupts are enabled, the most typical and general
program setup for the Reset and Interrupt Vector Addresses in ATmega328/328P is:
The MCU Control Register controls the placement of the Interrupt Vector table.
MCUCR – MCU Control Register
Note:
• Bit 1 – IVSEL: Interrupt Vector Select
When the IVSEL bit is cleared (zero), the Interrupt Vectors are placed at the start of the Flash
memory. When this bit is set (one), the Interrupt Vectors are moved to the beginning of the Boot
Loader section of the Flash. The actual address of the start of the Boot Flash Section is deter-
mined by the BOOTSZ Fuses. Refer to the section
Self-Programming” on page 279
tables, a special write procedure must be followed to change the IVSEL bit:
