1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader address at
2. When the IVSEL bit in MCUCR is set, Interrupt Vectors will be moved to the start of the Boot
reset, see
Flash Section. The address of each Interrupt Vector will then be the address in this table
added to the start address of the Boot Flash Section.
