Caution:
Concurrent and nested management
The following
first is called concurrent mode and does not allow an interrupt to be interrupted, unlike the
nested mode in
lowest to the highest: MAIN, IT5, IT4, IT3, IT2, IT1, IT0. The software priority is given for
each interrupt.
A stack overflow may occur without notifying the software of the failure.
