Section 5 Interrupt Controller
Figure 5.7 shows a block diagram of the priority decision circuit.
Interrupt Acceptance Control and 3-Level Control: In interrupt control modes 0 and 1,
interrupt acceptance control and 3-level mask control is performed by means of the I and UI bits in
CCR, and ICR (control level).
Table 5.6 shows the interrupts selected in each interrupt control mode.
