1. Do not use the single-step interrupt. For development tools only.
Interrupt Factor
There are 4 bytes in one vector. Set the starting address of interrupt routine in each vector table.
When an interrupt request is acknowledged, the CPU branches to the address set in the
corresponding interrupt vector. Figure 11.2 shows the Interrupt Vector.
The fixed vector tables are allocated addresses 0FFDCh to 0FFFFh. Table 11.1 lists the Fixed Vector
Tables. The vector addresses (H) of fixed vectors are used by the ID code check function. For
details, refer to 18.3 Functions To Prevent Flash Memory from Rewriting.
