10.1.4 Interrupts and Interrupt Vector
• Fixed Vector Tables
The fixed vector tables are allocated to the addresses from 0FFDC
lists the fixed vector tables. In the flash memory version of microcomputer, the vector ad-
dresses (H) of fixed vectors are used by the ID code check function. For details, refer to Sec-
tion 17.3, “Functions to Prevent Flash Memory from Rewriting.”
One interrupt vector consists of 4 bytes. Set the start address of each interrupt routine in the respec-
tive interrupt vectors. When an interrupt request is accepted, the CPU branches to the address set in
the corresponding interrupt vector. Figure 10.2 shows the interrupt vector.
