1.10 Vector Tables
Chapter 1 Overview
Interrupt vector tables are the only vector tables. There are two types of interrupt vector tables: fixed and
variable.
Figure 1.10.1 Fixed Vector Table
1.10.1 Fixed Vector Tables
A fixed vector table is an address-fixed vector table. Part of the interrupt vector table is allocated to
addresses 0FFDC
Interrupt vector tables are composed of four bytes per table. Each vector table must contain the inter-
rupt handler routine’s entry address.
