Section 5 Interrupt Controller

• Interrupt priority register K (IPRK)
• Interrupt priority register L (IPRL)
• Interrupt priority register O (IPRO)
5.3.1
The IPR registers are thirteen 8-bit readable/writable registers that set priorities (levels 7 to 0) for
interrupt sources 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.
