When the BOOTRST Fuse is programmed and the Boot section size set to 2K bytes, the
most typical and general program setup for the Reset and Interrupt Vector Addresses is:
When the BOOTRST Fuse is programmed, the Boot section size set to 2K bytes and the
IVSEL bit in the GICR Register is set before any interrupts are enabled, the most typical
and general program setup for the Reset and Interrupt Vector Addresses is:
