_______
One interrupt vector consists of 4 bytes. Set the start address of each interrupt routine in the respective
interrupt vectors. When an interrupt request is accepted, the CPU branches to the address set in the
corresponding interrupt vector. Figure 9.2.1 shows the interrupt vector.

The fixed vector tables are allocated to the addresses from FFFDC
fixed vector tables. In the flash memory version of microcomputer, the vector addresses (H) of fixed
vectors are used by the ID code check function. For details, refer to the section 17.3 Flash Memory
Rewrite Disabling Function.
