Table 20. Reset and Interrupt Vectors Placement
Note:
The most typical and general program setup for the Reset and Interrupt Vector
Addresses in ATmega8535 is:
When the BOOTRST Fuse is unprogrammed, 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:
