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
Labels Code
Comments
0x00000
RESET: ldi
r16,high(RAMEND); Main program start
0x00001
