6. INTERRUPTS
6.4
Interrupts and Interrupt Vector
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 6.2 shows the interrupt vector.

Interrupt Vector
Fixed Vector Tables
The fixed vector tables are allocated to the addresses from FFFDC16 to FFFFF16. Table 6.1 lists the 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 "flash memory rewrite disabling function".

Note: Do not normally use this interrupt because it is provided exclusively for use by development sup-
port tools.
If the contents of address
FFFE716 is FF16, program ex-
ecution starts from the address
shown by the vector in the
relocatable vector table.
