5.6.4
Table 5.4 shows interrupt response times – the interval between generation of an interrupt request
and execution of the first instruction in the interrupt handling routine. The symbols for execution
states used in table 5.4 are explained in table 5.5.
This LSI is capable of fast word transfer to on-chip memory, so allocating the program area in on-
chip ROM and the stack area in on-chip RAM enables high-speed processing.

Total (using on-chip memory)
2. In the case of the MULXS or DIVXS instruction
3. Prefetch after interrupt acceptance or for an instruction in the interrupt handling routine.
4. Internal operation after interrupt acceptance or after vector fetch
5. Not available in this LSI.
6. When setting the SP value to 4n, the interrupt response time is S
