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 10.2 shows the Interrupt Vector.
10.4.1 Fixed Vector Tables
The fixed vector tables are allocated to the addresses from FFFDCh to FFFFFh. Table 10.1 lists the Fixed
Vector Tables. In the flash memory version of MCU, the vector addresses (H) of fixed vectors are used by
the ID code check function. For details, refer to 21.2 Functions to Prevent Flash Memory from Rewriting.
1. Do not normally use this interrupt because it is provided exclusively for use by development tools.
2. If the contents of address FFFE7h is FFh, program execution starts from the address shown by the
