/*
 * The C64X+ core has 16 IRQ vectors. One each is used by Reset and NMI. Two
 * are reserved. The remaining 12 vectors are used to route SoC interrupts.
 * These interrupt vectors are prioritized with IRQ 4 having the highest
 * priority and IRQ 15 having the lowest.
 *
 * The C64x+ megamodule provides a PIC which combines SoC IRQ sources into a
 * single core IRQ vector. There are four combined sources, each of which
 * feed into one of the 12 general interrupt vectors. The remaining 8 vectors
 * can each route a single SoC interrupt directly.
