/* Interrupt Matrix
 *
 * The Interrupt Matrix embedded in the ESP32 independently allocates
 * peripheral interrupt sources to the two CPUs’ peripheral interrupts.
 * This configuration is highly flexible in order to meet many different
 * needs.
 *
 * Features
 * - Accepts 71 peripheral interrupt sources as input.
 * - Generates 26 peripheral interrupt sources per CPU as output (52 total).
 * - CPU NMI Interrupt Mask.
 * - Queries current interrupt status of peripheral interrupt sources.
 *
 * Peripheral Interrupt Source
 *
 * ESP32 has 71 peripheral interrupt sources in total. 67 of 71 ESP32
 * peripheral interrupt sources can be allocated to either CPU.  The four
 * remaining peripheral interrupt sources are CPU-specific, two per CPU.
 *
 * - GPIO_INTERRUPT_PRO and GPIO_INTERRUPT_PRO_NMI can only be allocated to
 *   PRO_CPU.
 * - GPIO_INTERRUPT_APP and GPIO_INTERRUPT_APP_NMI can only be allocated to
 *   APP_CPU.
 *
 * As a result, PRO_CPU and APP_CPU each have 69 peripheral interrupt
 * sources.
