Overview

The Vectored Interrupt Controller (VIC) module reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the CPU. This module includes the following major features:

The VIC module assembles all of the interrupt request signals and resolves the interrupts based on both a fixed natural order priority (i.e., determined by the IVT), and a user-assigned priority (i.e., determined by the IPRx registers), thereby eliminating scanning of interrupt sources.
