There is one CTPR on this device, shown in
Software must write the priority of the current processor task in the CTPR. 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 the core if the following apply:
Priority levels from 0 (lowest) to 15 (highest) are supported. Setting the task priority to 15 masks all
interrupts to the processor. Hardware sets the task register to 0x0000_000F during reset or when the Px
field of the processor initialization register is set.

Processor Current Task Priority Register (CTPR)
Reserved
Processor 0. Determines if processor 0 receives the interrupt. (write only).
0 Processor 0 does not receive the interrupt.
1 Directs the interrupt to processor 0.
Reserved
CTPR[TASKP] = 0xF, no interrupts are signaled to the processor.
