6.3.4
Interrupt priority registers are nine 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 6.2 Interrupt Request Sources, Vector Address, and Interrupt Priority Level.
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.)
