Interrupts
• Variable vector tables
The addresses in the variable vector table can be modified, according to the user's setting. Indicate the
first address using the interrupt table register (INTB). The 256-byte area subsequent to the address the
INTB indicates becomes the area for the variable vector tables. One vector table comprises four bytes.
Set the first address of the interrupt routine in each vector table. Table 6-2 shows the interrupts assigned
to the variable vector tables and addresses of vector tables.
