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.

5.6.1
In interrupt control mode 0, interrupt requests other than NMI and address breaks are masked by
ICR and the I bit of the CCR in the CPU. Figure 5.4 shows a flowchart of the interrupt acceptance
operation.
