ATmega16M1/32M1/64M1
Moving Interrupts Between Application and Boot Space
When the BOOTRST Fuse is programmed and the Boot section size set to 2 Kbytes, the most
typical and general program setup for the Reset and Interrupt Vector Addresses in
ATmega16M1/32M1/64M1 is:
When the BOOTRST Fuse is programmed, the Boot section size set to 2 Kbytes 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 ATmega16M1/32M1/64M1 is:
The MCU Control Register controls the placement of the Interrupt Vector table.
