2.7.4 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 2.7.2 shows the interrupt vector.
Fixed Vector Tables
The fixed vector tables are allocated to the addresses from FFFDC16 to FFFFF16. Table 2.7.1 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".
Table 2.7.1. Fixed Vector Tables
If the contents of address
FFFE716 is FF16, program ex-
ecution starts from the address
shown by the vector in the
relocatable vector table.
