Abstract
A circuit configuration and a method for priority selection of interrupts for a microprocessor in an integrated circuit which includes a central processing unit, a central interrupt node connected to the central processing unit, N interrupt sources for presenting interrupt requests to the central processing unit, peripheral interrupt nodes each being connected to a respective one of the N interrupt sources. A common interrupt bus is connected to the peripheral interrupt nodes and to the central interrupt node. The method for priority selection includes activating the interrupt bus in a prioritizing round in accordance with a priority value with a peripheral interrupt node assigned to an interrupt source in the presence of an interrupt request of the interrupt source.
