Chapter 1 Overview
Figure 1.10.2 Variable Vector Table
1.10.2 Variable Vector Tables
A variable vector table is an address-variable vector table. Specifically, this type of vector table is a 256-
byte interrupt vector table that uses the value indicated by the interrupt table register (INTB) as the entry
address (IntBase). Figure 1.10.2 shows a variable vector table.
Variable vector tables are composed of four bytes per table. Each vector table must contain the inter-
rupt handler routine’s entry address.
Each vector table has software interrupt numbers (0 to 63), which are used by the INT instruction.
Interrupts for the on-chip peripheral functions of each M16C model are allocated to software interrupt
numbers 0 through 31.
