Exception Model and System Interrupt Map

6.2.6.1

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”.
