6.2.7.1 Exception Model and System Interrupt Map
The following table lists the exception model supported by NuMicro^™ M058S 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”.
