5.6
The interrupt controller has two modes: interrupt control mode 0 and interrupt control mode 1.
Interrupt operations differ depending on the interrupt control mode. NMI and address break
interrupts are always accepted except for in the reset state. The interrupt control mode is selected
by SYSCR. Table 5.7 shows the interrupt control modes.
Table 5.7
Figure 5.6 shows a block diagram of the priority determination circuit.

Description
Interrupt mask control is performed by
the I bit. Priority levels can be set with
ICR.
3-level interrupt mask control is
performed by the I and UI bits. Priority
levels can be set with ICR.
