5.5.5
The H8S/2138 Group and H8S/2134 Group are capable of fast word access to on-chip memory,
and high-speed processing can be achieved by providing the program area in on-chip ROM and
the stack area in on-chip RAM.
Table 5.8 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 used in table
5.8 are explained in table 5.9.
