44 * @section Introduction
45 *
46 * @subsection xxx Overview
47 * The CPINTC is the interrupt controller which handles the system interrupts
48 * for the host, processes & prioritizes them and then is responsible for
49 * delivering these to the host.
50 *
51 * @subsection References
52 * -# CPINTC Architecture Specification.
53 *
54 * @subsection Assumptions
55 * The abbreviations CPINTC, cpintc have been used throughout this
56 * document to refer to Interrupt Controller.
