(b) Interrupt/exception table
The V850E/IA2 increases the interrupt response speed by assigning handler addresses corresponding to
interrupts/exceptions.
The collection of these handler addresses is called an interrupt/exception table, which is located in the
internal ROM area. When an interrupt/exception request is acknowledged, execution jumps to the
handler address, and the program written at that memory location is executed. Table 3-3 shows the
sources of interrupts/exceptions, and the corresponding addresses.
Remark
When in ROMless mode, in order to resume correct operation after reset, provide a handler
address to the reset routine at address 0 of the external memory.
