• Fixed vector tables
Interrupt source
The fixed vector table is a table in which addresses are fixed. The vector tables are located in an area
extending from FFFDC
interrupt routine in each vector table. Table 4.1.1 shows the interrupts assigned to the fixed vector
tables and addresses of vector tables.
If an interrupt request is accepted, a program branches to the interrupt routine set in the interrupt
vector table. Set the first address of the interrupt routine in each vector table. Two types of interrupt
vector tables are available — fixed vector table in which addresses are fixed and variable vector
table in which addresses can be varied by the setting.
