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 interrupts and address
break interrupts are always accepted except for in reset state or in hardware standby mode. The
interrupt control mode is selected by SYSCR. Table 5.4 shows the interrupt control modes.
Table 5.4
Figure 5.3 shows a block diagram of the priority decision 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 bit. Priority levels
can be set with ICR.
