/* Interrupt Matrix
 *
 * The Interrupt Matrix embedded in the ESP32C3 independently allocates
 * peripheral interrupt sources to the CPUs’ peripheral interrupts.
 * This configuration is highly flexible in order to meet many different
 * needs.
 *
 * Features
 * - Accepts 62 peripheral interrupt sources as input.
 * - Generate 31 peripheral interrupts to CPU as output.
 * - Queries current interrupt status of peripheral interrupt sources.
