Interrupt/exception table
The V850ES/SA2 and V850ES/SA3 speed up the interrupt response time by fixing handler addresses
corresponding to interrupts/exceptions.
A collection of these handler addresses is called an interrupt/exception table, which is mapped to the internal
ROM area. When an interrupt/exception is acknowledged, execution jumps to a handler address and the
program in the area starting from that address is executed. Table 3-3 shows the interrupt/exception sources
and corresponding addresses.
