Evaluating the mcusr register of the Atmel AVR ATmega 328p
Work in progress

The Interrupt Vectors can be moved to the start of the Boot Flash section by setting the IVSEL bit in the MCU Control Register (MCUCR). Refer to ”Interrupts” on page 66 for more information

The Reset Vector can also be moved to the start of the Boot Flash section by programming the BOOTRST Fuse, see ”Boot Loader Support – Read-While-Write Self-Programming” on page 272

ATmega328/328P, the Reset Vector is affected by the BOOTRST fuse, and the Interrupt Vector start address is affected by the IVSEL bit in MCUCR.
