There are four bytes in each interrupt vector. Set the starting address of an interrupt routine in each interrupt vector.
When an interrupt request is acknowledged, an interrupt routine is executed from the address set in its interrupt
vector. Figure 11.3 shows an interrupt vector.
The fixed vector table is allocated in addresses FFFFDCh to FFFFFFh. Table 11.1 lists the fixed vector table.
The ID code which is used for the ID code check function of the flash memory is stored to the part of the fixed
vector table. Refer to 26.2.2 ID Code Check Function for details.
The relocatable vector table occupies 256 bytes beginning from the address set in the INTB register. Tables 11.2
and 11.3 list the relocatable vector table.
Set an even address to the starting address of the vector set in the INTB register to increase the interrupt
sequence execution rate.
