Notes:

1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader

address at reset, see “Memory Programming” on page 342.

2. When the IVSEL bit in MCUCR 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.
