• Variable vector tables
The addresses in the variable vector table can be modified, according to the user’s settings. Indi-
cate 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 com-
prises four bytes. Set the first address of the interrupt routine in each vector table. Table 2.7.2
shows the interrupts assigned to the variable vector tables and addresses of vector tables.

Note 1: Address relative to address in interrupt table register (INTB).
Note 2: It is selected by interrupt request cause bit (bit 6, 7 in address 035F16 ).
Note 3: When IIC mode is selected, NACK and ACK interrupts are selected.
