5.4.5
The H8S/2357 Group is capable of fast word transfer instruction to on-chip memory, and the program area is provided in
on-chip ROM and the stack area in on-chip RAM, enabling high-speed processing.
Table 5-9 shows interrupt response times - the interval between generation of an interrupt request and execution of the
first instruction in the interrupt handling routine. The execution status symbols used in table 5-9 are explained in table 5-
10.
Table 5-9
Notes: 1. Two states in case of internal interrupt.

2. Refers to MULXS and DIVXS instructions.
3. Prefetch after interrupt acceptance and interrupt handling routine prefetch.
4. Internal processing after interrupt acceptance and internal processing after vector fetch.
