There are 4 bytes in each vector. Store the start 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 11.2 shows an Interrupt Vector.
1. Do not use this interrupt. It is provided exclusively for use in development tools.
2. For the voltage monitor 1 or voltage monitor 2 interrupt, non-maskable or maskable can be selected by the
The fixed vector table is allocated at addresses 0FFDCh to 0FFFFh.
Table 11.3 lists the Fixed Vector Table. The vector addresses (H) of the fixed vectors are used by the ID code
check function. Refer to 26.4 Functions to Prevent Flash Memory from being Rewritten for details.
