Notes:
1. Applies only to Atmel ATmega1284P.
When the BOOTRST Fuse is unprogrammed, 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 typical and
general program setup for the Reset and Interrupt Vector Addresses is:
Address
