6.2.6.1 Exception Model and System Interrupt Map
Table 6-2 lists the exception model supported by the NuMicro^® M0519 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 “0” and the lowest priority is denoted as “3”. The default priority
of all the user-configurable interrupts is “0”. Note that priority “0” is treated as the fourth priority on
the system, after three system exceptions “Reset”, “NMI” and “Hard Fault”.
