7.3.3
IPR sets priory (levels 7 to 0) for interrupts other than NMI.
Setting a value in the range from B'000 to B'111 in the 3-bit groups of bits 14 to 12, 10 to 8, 6 to 4,
and 2 to 0 assigns a priority level to the corresponding interrupt. For the correspondence between
the interrupt sources and the IPR settings, see table 7.2.
