128 KB of memory, addresses 00000H to 1FFFFH, is provided as physical internal ROM (flash
memory).
Also, in the remaining area (20000H to FFFFFH), the image of 00000H to 1FFFFH can be seen.

Interrupt/exception table
(b) Interrupt/exception table
The V850E/MS1 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 granted, execution jumps to the handler
address, and the program written at that memory is executed. Table 3-3 shows the sources of
interrupts/exceptions, and the corresponding addresses.
Remark
When in ROM-less modes 0 and 1, or in the case of the
µ
PD703100 or 703100A, the internal
ROM area becomes an external memory area. In order to restore correct operation after reset,
provide a handler address to the reset routine in address 0 of the external memory.
