10.3.2
The level seven interrupt requests cannot have their levels reassigned. However, any of the remaining
peripheral interrupt requests can be reassigned as the highest priority maskable requests using these two
registers (INTC_PL6P7 and INTC_PL6P6). The vector number associated with the interrupt requests does
not change. Rather, only the interrupt request's level and priority are altered, based on the contents of the
INTC_PL6P{7,6} registers.
