Section 6 Interrupt Controller
6.6
The interrupt controller has two modes: interrupt control mode 0 and interrupt control mode 2.
Interrupt operations differ depending on the interrupt control mode. The interrupt control mode is
selected by INTCR. Table 6.3 shows the differences between interrupt control mode 0 and
interrupt control mode 2.

Description
The priorities of interrupt sources are fixed at
the default settings.
Interrupt sources except for NMI is masked by
the I bit.
8 priority levels except for NMI can be set with
IPR.
8-level interrupt mask control is performed by
bits I2 to I0.
