563 This FreeRTOS port supports strict priority-based nesting of interrupts.
564 An interrupt may only nest on top of one of strictly lower priority.
565 Equal priority interrupts concurrently pending are handled in an
566 application-defined sequence before any lower priority interrupts
568 interrupt level (PS.INTLEVEL) is used to control the interrupt priority

610     If the cause is a level 1 (low-priority) or medium-priority interrupt,
611     the handler enables all interrupts above that priority level after
628     one, before calling the user handler. This allows a higher priority
629     interrupt to pre-empt the lower priority handler.
633     Medium priority interrupts are those at levels 2 up to XCHAL_EXCM_LEVEL,
636     Interrupt levels above XCHAL_EXCM_LEVEL are of the high-priority class.
637     The Xtensa hardware documentation considers medium priority interrupts
638     to be a special case of high-priority interrupts, but from a software

649     High priority handlers may not directly interact with FreeRTOS at all,
