1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader address at
reset, see
“Boot Loader Support – Read-While-Write Self-Programming” on page
2. When the IVSEL bit in GICR is set, interrupt vectors will be moved to the start of the Boot
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.
