Also im Datenblatt vom Mega32 steht folgendes:
The list also determines the priority levels of the different interrupts. The lower the address the higher is the
priority level. RESET has the highest priority, and next is INT0 – the External Interrupt Request0. The Interrupt Vectors can be moved to the start of the Boot Flash section by setting the IVSEL bit in the General Interrupt Control Register (GICR).

Das bedeutet denk ich mal soviel wie Prio 1. RESET Prio 2. Int0 Prio 3. Int1 Prio 4 Int2
Ich denke sowas meintest du oder?
