* If two or more interrupts are requested simultaneously, they are handled in order of priority level,
as set in registers IPRA to IPRF. If they have the same priority level because they are requested
from the same on-chip supporting module, they are handled in a fixed priority order within the
module. If they are requested from different modules to which the same priority level is
assigned, they are handled in the order indicated in the right-hand column.
