Section 6 Interrupt Controller
6.3.2
IPR are fourteen 16-bit readable/writable registers that set priorities (levels 7 to 0) for interrupts
other than NMI. The correspondence between interrupt sources and IPR settings is shown in table
6.2 (Interrupt Sources, Vector Addresses, and Interrupt Priorities). Setting a value in the range
from H'0 to H'7 in the 3-bit groups of bits 14 to 12, 10 to 8, 6 to 4, and 2 to 0 sets the priority of
the corresponding interrupt. IPR should be read in word size.
