Figure 6. AT90S4433 Memory Maps

A flexible interrupt module has its control registers in the I/O space with an additional

Global Interrupt Enable bit in the Status Register. All the different interrupts have a sep-

arate Interrupt Vector in the Interrupt Vector table at the beginning of the Program

memory. The different interrupts have priority in accordance with their Interrupt Vector

position. The lower the Interrupt Vector address, the higher the priority.
