Section 6 Interrupt Controller (INTC)
Note:
6.3.4
Interrupt priority registers are thirteen 16-bit readable/writable registers that set priority levels
from 0 to 15 for interrupts except NMI. For the correspondence between interrupt request sources
and IPR, refer to table 6.3. Each of the corresponding interrupt priority ranks are established by
setting a value from H'0 to H'F in each of the four-bit groups 15 to 12, 11 to 8, 7 to 4 and 3 to 0.
Reserved bits that are not assigned should be set H'0 (B'0000).
