6.2.6.1 Exception Model and System Interrupt Map
The following table lists the exception model supported by NuMicroï¤ M0518 series. Software can
set four levels of priority on some of these exceptions as well as on all interrupts. The highest
user-configurable priority is denoted as â0â and the lowest priority is denoted as â3â. The default
priority of all the user-configurable interrupts is â0â. Note that priority â0â is treated as the fourth
priority on the system, after three system exceptions âResetâ, âNMIâ and âHard Faultâ.
