Interrupts and Interrupt 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. Figure 1.12.2 shows format for
specifying interrupt vector addresses.
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.
Fixed vector tables
The fixed vector table is a table in which addresses are fixed. The vector tables are located in an area
extending from FFFDC
16
to FFFFF
16
. One vector table comprises four bytes. Set the first address of
interrupt routine in each vector table. Table 1.12.1 shows the interrupts assigned to the fixed vector
tables and addresses of vector tables.
