Section 5 Interrupt Controller
5.3.1
The IPR registers are eleven 8-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 5.2. Setting a
value in the range from H'0 to H'7 in the 3-bit groups of bits 0 to 2 and 4 to 6 sets the priority of
the corresponding interrupt.
