5.4.5
The chip 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.
