Note: 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.

Field Description
7–6 Reserved, should be cleared.
5–3
IL
Interrupt level. Indicates the interrupt level assigned to each interrupt input.
2–0
IP
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 always reads as 000b.
