1. Do not use these interrupts. They are for use by development tools only.
There are 4 bytes in each vector. Set the starting address of an interrupt routine in each interrupt vector. When
an interrupt request is acknowledged, the CPU branches to the address set in the corresponding interrupt vector.
Figure 12.2 shows an Interrupt Vector.
The fixed vector tables are allocated addresses 0FFDCh to 0FFFFh.
Table 12.1 lists the Fixed Vector Tables. The vector addresses (H) of fixed vectors are used by the ID code
check function. For details, refer to 20.3 Functions to Prevent Rewriting of Flash Memory.
