5.1 Outline of Interrupt
Chapter 5
When an interrupt request is acknowledged, control branches to the interrupt routine that is set to an inter-
rupt vector table. Each interrupt vector table must have had the start address of its corresponding interrupt
routine set. For details about the interrupt vector table, refer to Section 1.10, “Vector Table.”

5.1.1 Types of Interrupts
Figure 5.1.1 lists the types of interrupts. Table 5.1.1 lists the source of interrupts (nonmaskable) and the
fixed vector tables.
*1 Peripheral I/O interrupts are generated by the peripheral functions built into the microcomputer system.
