Interrupt Controller Modules
13.2.1.6 Interrupt Control Register (ICRnx, (x = 1, 2,..., 63))
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.
