In any case, the Top Level Interrupt uses the third fixed vector at addresses 4 and 5 in program memory. As the name im- plies, it has a fixed priority that is higher than any other interrupt request. Though it does not clear the IEN bit when acknowledged, unlike all other interrupt requests, its service routine cannot be interrupted by any cause, including the Top Level Interrupt itself. The simplified block diagram is the following: Figure 21 .
