Section 5 Interrupt Controller
5.3.1
The IPR registers are thirteen 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'7 to H'0 in the 3-bit groups of bits 2 to 0 and 6 to 4 sets the priority of
the corresponding interrupt.
