6.3.4
Interrupt priority registers are ten 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. 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.)
