Interrupt Controller Modules
10.3.6
Each ICRnx specifies the interrupt level (1-7) and the priority within the level (0-7). All ICRnx registers
can be read, but only ICRn8 to ICRn63 can be written. It is the responsibility of the software to program
the ICRnx registers with unique and non-overlapping level and priority definitions. Failure to program the
ICRnx registers in this manner can result in undefined behavior. If a specific interrupt request is completely
unused, the ICRnx value can remain in its reset (and disabled) state.

Interrupt level. Indicates the interrupt level assigned to each interrupt input.
Interrupt priority. Indicates the interrupt priority for internal modules within the interrupt-level
assignment. 000b represents the lowest priority and 111b represents the highest. For the fixed level
interrupt sources, the priority is fixed at the midpoint for the level, and the IP field will always read as
000b.
