There is one CTPR per processor core on this device as shown in
Software must write the priority of the current processor core task in the CTPR for each core. The PIC uses
this value for comparison with the priority of incoming interrupts. Given several concurrent incoming
interrupts, the highest priority interrupt is asserted to that core if the following apply:
