InterruptMitsubishi microcomputersM16C / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTER• Variable vector tablesThe addresses in the variable vector table can be modified, according to the user’s settings. Indicatethe first address using the interrupt table register (INTB). The 256-byte area subsequent to the addressthe INTB indicates becomes the area for the variable vector tables. One vector table comprisesfour bytes. Set the first address of the interrupt routine in each vector table. Table 4.1.2 shows theinterrupts assigned to the variable vector tables and addresses of vector tables.Table 4.1.2.
