When the BOOTRST Fuse is programmed and the Boot section size set to 8K 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 8K bytes and the
IVSEL bit in the MCUCR Register is set before any interrupts are enabled, the most typ-
ical and general program setup for the Reset and Interrupt Vector Addresses is:
The General Interrupt Control Register controls the placement of the Interrupt Vector
table.
