Figure 4. The AT90S8515 AVR RISC Architecture
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 sepa-
rate 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.
