10.1.4 Interrupts and Interrupt Vector
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.
• Fixed Vector Tables
Jan 27, 2006
The fixed vector tables are allocated to the addresses from 0FFDC
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 Section 17.3, “Functions to
Prevent Flash Memory from Rewriting.”
