Nonmaskable interrupt input pin NMI
Interrupt request input pins
Interrupt request output pin
5.1.4
The interrupt controller has six registers as listed in table 5.2. These registers are used for setting
interrupt priority levels and controlling the detection of external interrupt input signals.

Name
Interrupt priority register A
Interrupt priority register B
Interrupt priority register C
Interrupt priority register D
Interrupt priority register E
Interrupt control register
Notes: 1. H'8000 when pin NMI is high, H'0000 when pin NMI is low.
2. Only the values of bits A27–A24 and A8–A0 are valid; bits A23–A9 are ignored. For
